Frequently Asked Questions

Products

I’m really confused about the different type of materials and their applications.

Sorry for the confusion.

Essentially we produce 4 types of mineral based materials, RP, RB, SP and ST. The recycled versions of each of those types are coming up in the future.

  • RP is the equivalent to paper type.
  • RB is the equivalent to board type.
  • SP stands for Safe Performance (food grade), ideal for food wrapping such as burger wraps
  • ST stands for Strict Thermal, good for moldable applications such as disposable dishes or food containers.

For SP you have to consider Corona treatment if you want to have them printable. If you just want to use them as a replacement layer for OPP material applications, then you don’t need this type of treatment.
SP products are delivered in roll format and you can find variety of applications to be made as plastic alternative material.

Are Stone Paper® products cost-competitive compared to recycled paper?

Stone Paper® products are very cost-competitive compared to recycled papers.
Recycled paper on its own has a lot of advantages, but unfortunately some companies stretch too far by adding only 5% recycled material to pulp paper and claim being socially responsible.

There are hundreds of different grades of recycled papers in the market. In general we compete with most recycled options.

How is Yupo synthetic papers compared with Stone Paper® products in terms of cost, durability and environmental friendliness. Is Stone Paper® a suitable alternative product?

All materials, being virgin or recycled paper, plastic or any other synthetic material have their own suitable benefits for select applications. We’re sure great products such as Yupo synthetic paper is of no exception.
Most restaurant menus, plant tag labels, portable signage/displays, high end trail maps, aviation materials, airline safety instructions, PVC made labels and many other applications require special ink and special treatment.

Stone Paper® renewable mineral based products use conventional ink and no special treatment. they are a great complement to applications where plastic film or synthetic papers might not be suitable. Stone Paper® products offer customers the characteristics of a premium paper combined with compatibility of plastic at a fraction of the cost and at a far less environmental footprint.

Are Stone Paper® products produced in clean vacuum room?

Our food grade material is produced in clean vacuum room. Other type of materials can be produced in clean vacuum room as per client’s request.

What is the price comparison for cost of production of mineral based material against traditional or recycled products made with nonrenewable resources?

When comparing volume to volume, our mineral based material production is much more cost efficient compared to traditional products using nonrenewable resources. Its cost efficiency is attributed by its dry process technology, raw material sourcing and non-existent factors such as whitening, acid, bleach or water.

Who are the competitors globally manufacturing this type of material?

To the best of our knowledge we cannot think of any other manufacturer producing our Stone Paper® renewable substrate with the same quality and sustainability factors, at the same volume.

Would you say Stone Paper® products are ultimately a substitute for paper or plastic?

Stone Paper® products combine all the positive characteristics and capabilities of paper as well as all the competencies of plastic in one.
Our intention is not to replace or substitute any products. Stone Paper® products are an alternative mineral based material suited for applications where the advantages of paper and plastic are desired at the same time.

Applications

What applications are Stone Paper® products best suited for?

Even though there are endless applications suited for our Stone Paper® products, we still recommend the mineral material to be used as an alternative option to paper treated products such as paper treated with PE or Wax.
With benefits such as waterproof, tear resistant, fire retardant, and grease repellent, to name a few, Stone Paper® applications are only limited by your imagination. The sky is the limit. Everybody in their own field of expertise is welcome to try it out and see if it benefits them in any way.

Please refer to https://www.stonepapertech.com/products/ for most commercial and industrial applications.

Is there a specific temperature that any mineral material starts to crumble?

Our Stone Paper® products are sensitive to anything over 105 degrees Celsius during printing.
Eventhough our Stone Paper® products are not suitable for coffee cups, but they are perfectly fine for cold beverages.

Are Stone Paper® products suitable for IML (In Mould Labelling)? Would it print by normal offset or does it need special printing method and special ink?

Technically when using our Stone Paper® products for IML (In mould labelling), our roll of SP50 micron category would be most suitable. Many converters don’t disclose their technical knowhow for some of the applications, but we had great success with some of the tests we carried out with yogurt containers. The test showed our material’s great performance when fused onto the container. No special ink is required as our Stone Paper® products are very fast drying materials. As with any material being paper or plastic, we also have easy to follow instructions for printing which is normally provided to printers and converters for efficient and seamless service.

Are Stone Paper® products suitable for hot beverage cups such as tea or coffee?

Our Stone Paper® products tolerate temperature variances from -65 to +70 degrees Celsius. According to our tests till now, if water is boiled constantly for long period of time (tested up to 30 min) in a mineral material cup, the resin used as bonding agent starts to soften. Therefore for liability purposes we will not ensure the compatibility of the product for hot beverages. For cold beverage such as juices, the product is perfectly fine.

Are any of the Stone Paper® products suitable for heat sealing applications?

Currently the heat sealing time can only be performed at 70 hits per min, which means that only 70 units can be heat sealed per minute. This is well below the standard requirement of 165 per min for slow machines and 600 per min for ultra fast machines. Heat sealing is when a hot blade hits the 2 layers and blends / fuses them together. Traditionally with pulp paper, it is done by adding or laminating another layer of polymer onto the paper to give the heat sealing effect.

The issue we have faced which is now being worked on at the product development stage is that when the hot blade hits the mineral based material, the heat is transferred and absorbed by the minerals. The natural properties and characteristics of the minerals (also applicable for most minerals) is to absorb the heat without immediate releasing factor. This could be understood as our mineral is the same composition as eggshell, pure Calcium Carbonate. It is usually experienced with boiled egg as the eggshell doesn’t release the heat when taken off the stove. Therefore currently when the hot blade hits the paper, the heat is absorbed by the minerals without immediate release, resulting in direct affect onto the resin and shrinkage of the paper.

At the moment we’re experimenting a solution by adjusting the raw material absorbancy rate using nano technology. This involves treating the original rich mineral component at the molecular or atomic level, hence decreasing the heat absorbency ratio of the minerals with the hope that the treated mineral portion behaves according to our specifications.

This aspect of the finished product is undergoing further development and testing.

Printing

What type of printing methods is suitable for Stone Paper® products?

Stone Paper® products are suited for the following printing methods:

  • Web/Sheet Offset Lithographic
  • UV Web/Sheet Offset Lithographic
  • Flexographic
  • Gravure
  • Digital (Latex/ solid ink) low heat machines

Are Stone Paper® products suitable for digital printing machines?

Stone Paper® products are only suitable on select digital machines. Most digital machines are set to create high degree of heat (up to 400 degrees Celsius) to fuse the ink into the traditional paper. This creates a softening effect of the resin and therefore our Stone Paper® products start to soften. As a result the mineral based material could get wrinkled or jammed in the machine. Sometimes it could even show the preliminary shrinkage signs as it comes out of the machine which could fail the product in the quality control division of the finishing plant.

To be clear, not all digital machines create heat. There are some digital machines such as HP Indigo and Xerox 700-800 which do not. Because we don’t want to damage the market, we would rather not advertise digital capabilities until such time when we could bring the capability on board 100%. For the time being Stone Paper® products have only shown compatibility with HP Indigo and Xerox 700-800 machines.

Are Stone Paper® products suitable for office laser printers, photocopiers or toner printers?

No. Stone Paper® products are still not suitable for heatset laser printers or photocopiers because our mineral based material is photo-degradable, meaning its ability to degrade with the intensity of UV light. When it is used in laser printers and UV is exposed onto the material, it reacts to the UV light and starts the degrading mechanism. Therefore laser printers are a NO GO at this point in time.

Stone Paper® products are still under development for toner printers.

Do Stone Paper® products require special ink or treatment for print applications? Does it accommodate most post press applications?

Stone Paper® products can be printed using conventional ink without any special treatment. It can accommodate both water and soy-based inks.
Depending on the application, Stone Paper® products can also be gusseted, heat sealed, sewn, mounted with grommets, and outfitted with hemp, nylon, rope, or even economical TR cotton, etc…

Environmental Impact

Are Stone Paper® products recyclable and degradable?

The short answer is Yes, but under certain conditions. Our Stone Paper® products are recyclable, meaning the same product can be made from its own waste to produce renewable mineral based material. Our Stone Paper® products are also photo-degradable. Which means it degrades according to the intensity of natural UV light it is exposed to in the natural environment in different regions of the world. For instance, in very simple terms if our paper is used in Vancouver, Canada, it might take about a year and half to degrade. If in Saudi Arabia, it might take about 6 months. But that’s direct natural UV exposure without any barrier. That is not the case for printed materials exposed to sun by an office window. The photo-degradability for recycling purposes is only in the natural environment where there is direct UV exposure and interaction with other natural substances which play a degrading factor. When the non-toxic resin degrades, the molecules of the resin break down which gives it the effect of a very thin layer of brittle material such as dried paint or very fragile / brittle eggshell effect. Essentially when the resin’s molecule is broken down, the chemical properties of the matter changes and the rest of the materials are the same rich minerals which are abundant elements in nature.

Just need to touch a bit more with respect to recycling factors. Even though a recycling identification (no.2) has been assigned to this product, since the global volume of our Stone Paper® products are very low compared to the pulp paper, at its current low volume, Stone Paper® products can actually be put in any recycling stream such as paper, plastic, glass, etc.. without negatively having an adverse effect or damaging the existing recycling streams. Reason being is because some degree of mineral is used essentially in most products as a natural element. With the increase in volume of Stone Paper® products, the product will eventually find its own stream side by side with other recycling items.

The same applies with Plastic recycling stream.
There are a lot of greenwashing about our mineral based materials and its recycling aspects in the market. Below is a summary in a nutshell.

  • At present low volume Stone Paper® products are not recyclable in traditional recycling facilities. The reason is due to its low polymer and high calcium carbonate content, the recycling companies can’t justify the economics.
  • At present low volume Stone Paper® products can be discarded in virtually any waste stream.
  • At larger volumes Stone Paper® products have the capability to be recycled from its own waste to produce other renewable mineral based material with a 93% recycling results.

 

Should anyone be concerned with respect to the resin component and any toxicity in a landfill?

As previously mentioned, our mineral based materials are photodegradable, not biodegradable, not compostable.

Our resin is not naturally biodegradable since its molecular structure breaks down with the intensity of natural UV light.
When the resin’s molecular structure breaks down, it loses its elasticity and crumbles into pieces like a dried elastic band under pressure. By virtue of oxidation, the chemical properties of the resin are altered, hence the effectiveness of the resin is destroyed.

The entire degradability of the product is valid in certain natural environments consisting of constant UV exposure, natural interaction with other substances and chemical reactions present in the surrounding environment, etc….
To the best of our knowledge, with our Cradle to Cradle or regenerative design certification, which is the biometric approach to the design of products and system, there is hardly any concern with respect to the non-toxic resin component. Our certification models human industry on nature’s processes viewing materials as nutrients circulating in healthy, safe metabolisms. If there are still questions or concerns about our product’s resin component, please consult with a scientist for an independent advice.

How long does the non-toxic resin component take to degrade?

At its molecular level, our non-toxic resin takes about 6-18 months to start breaking down.

Can Stone Paper® products get recycled with paper? Can it be recycled with Plastic? Would the resin content contaminate any of the streams?

At the current low market volume for Stone Paper® products, compared to more than 400 million metric ton of traditional pulp paper in the recycling stream, we believe that our Stone Paper® products can be put into any recycling bin without having a negative adverse effect on the recycling stream. Eventhough our product will not be recycled with paper itself, this will eventually change when our volume reaches a level where a dedicated stream is created. Relatively speaking our Stone Paper® products volume are currently not even 1/10 of one percent of the global paper market. We’re currently introducing an innovative collection and repurposing program to our industrial clients as part of our waste management strategy. Please note this repurposing program is still at an experimental and development phase.
At higher volumes, meaning when our mineral based material gains momentum and captures larger market share, it is recommended to dispose our mineral based material in dedicated recycling bins as dedicated waste management companies will collect them for repurposing projects.

We believe at the current low volume, when our Stone Paper® material is disposed of with regular paper, the non-toxic resin portion will not have a negative adverse effect on the stream due to the extreme low percentage of non-toxic resin characteristic relative to the whole paper in recycling stream.
In the current paper recycling bins there are lots of plastic films on top of most prints (magazine covers, catalogues, brochures, business cards, boxes, packaging, store bags, etc…). Those plastic films made with polypropylene or even LDPE are normally applied as protective layer on top of most printed items to protect and lock / settle the ink. Those protective plastic films are more toxic than the low level non-toxic resin content in our Stone Paper® products.

The same applies with Plastic recycling stream.
There are a lot of greenwashing about our mineral based materials and its recycling aspects in the market. Below is a summary in a nutshell.

  • At present low volume Stone Paper® products are not recyclable in traditional recycling facilities. The reason is due to its low polymer and high calcium carbonate content, the recycling companies can’t justify the economics.
  • At present low volume Stone Paper® products can be discarded in virtually any waste stream.
  • At larger volumes Stone Paper® products have the capability to be recycled from its own waste to produce other renewable mineral based material with a 93% recycling results.

 

How could Stone Paper® products be useful in landfills?

In some countries such as New Zealand and Australia, some of the waste management companies use minerals as an expediting agent for processing waste. Our renewable material with high level of rich mineral content contributes to a significant level of savings for waste management companies in their waste processing system.

Can you elaborate on the photo-degradability of Stone Paper® products?

As previously mentioned, our mineral based material is photodegradable, not biodegradable, not compostable.
Under the notion of biodegradability, organic substances can take up-to 20 years to decompose by bacteria or other living organisms. Our mineral based material is inorganic, therefore it doesn’t decompose by bacteria or any other living organisms.
In the eyes of the Federal Trade Commission, FTC, if something is biodegradable it must breakdown to elements of nature in one year using customary disposal methods. In the US, customary disposal of solid materials means a landfill, an incinerator, or a recycling facility. Not a composting facility. Not your backyard garden.

The notion of biodegradability doesn’t apply to our product since the main element of the substance is minerals. This substance is already a natural element of earth which in plain language could be considered as already “decomposed”. Therefore the only content of Stone Paper® product which needs to be broken down is the low level non-toxic resin.
All in all, as a renewable material, our Stone Paper® product would in reality qualify more to be a “biodegradable” material in the eyes of the FTC than any other product, Even though its structure and composition do not even apply to the term.

As it was indicated previously, our resin, with inorganic properties is not naturally biodegradable, therefore its molecular structure needs to breakdown with the intensity of natural UV light. Since natural UV light (with or without sunlight) is always present it automatically penetrates and breaks down the molecular structure of the resin component, effectively oxidizing and enabling it to lose its molecular effectiveness. As a scientist once put it using paper as an analogy, if it is burnt or has an oxidation effect, meaning the molecules have broken down, it’s not called paper anymore.

For instance, Stone Paper® products sitting on an office desk by the window doesn’t decompose since the natural environmental factors aren’t present.

By Stone Paper® products being photo-degradable, does that mean if we produce books or boxes from Stone Paper® products and leave them in the sun which includes UV, the paper will disintegrate?

No, The entire degradability of the product is valid when in presence of certain feasible natural environmental conditions consisting of factors such as UV exposure, natural interaction with other external elements, natural substances, as well as chemical reactions present in the surrounding environment, etc….

What are the effects of mineral based products on animals such as cows and dogs on consumption?

Even though some of our Stone Paper® products are dedicated FDA compliant, our consumption recommendations and notice standards are the same as any other non-food materials for live beings.

Can the material be made biodegradable?

Photo-degradability is another aspect of our Stone Paper® products. Compared to other products made with nonrenewable resources, we have the capability to customize the technology to match biodegradability standards. In fact in the very near future we can customize any of our mineral based materials to the point of assigning length of time for its slow or rapid degradation. Our current Stone Paper® products degrade within 6-18 months under natural conditions. Please refer to the rest of the FAQ segments for more clarifications.

Certifications

Does FSC or PEFC certifications apply to Stone Paper® products?

We’re in full support of all parties contributing in their own way to the rainforest protection either through forest management initiatives or other environmental programs. Due to the revolutionary manufacturing process for mineral based material, the environmental and sustainability certifications for Stone Paper® products are different to wood fibre paper. No forest management certification, such as FSC, or PEFC is required for Stone Paper® products as no cellulose fibre is present.

Are Stone Paper® products FDA certified?

There is one type of our Stone Paper® product which is FDA compliant. What needs to be noted for FDA compliance is that even though a product might be FDA approved, those approvals are only general and for each food application specific approvals must be obtained.

Reason: Different foods have different chemical properties and therefore we must be absolutely certain that the food application being used in connection with our mineral based material doesn’t create any adverse chemical reaction to negatively affect the integrity of the food or characteristics of the material. For example to use Stone Paper® products for wrapping bread is fine, but to use it for wrapping lemon might not be. It’s not the lemon or the material itself that is the issue. If the paper is not properly converted into a food wrapping paper, the lemon’s acidity touching the edge of the material horizontally, without the edge being protected by protective coating, might create a chemical reaction when in contact with the non-hazardous mineral and therefore might not be compliant with FDA regulations. This is currently being resolved with wax or an additional layer of PE in the pulp paper industry. We can resolve this issue by double folding the edge of the material so that the horizontal edge do not come in contact with food. Other innovative solutions are currently being experimented for development.

FDA Compliance Certificate for the code of Federal Regulations with respect to soluble and extractable matter as an environmental material and food grade suitability. http://www.sgs.com/laboratories?catId=10655&lobId=5548&type=service

Many FDA and other related tests have been carried out on Stone Paper® products and copies of these tests are available upon request should a particular use of our Stone Paper® material demand such test results and certifications.

What does REACH, and ROHS certifications mean?

Stone Paper® products have achieved ROHS & REACH Testing (SGS) www.rohs-international.com. No chemicals, heavy metals or minerals (heavy metals) known to be dangerous to humans or the environment are detected. http://echa.europa.eu/regulations/reach

These certifications mostly apply for applications where our products are a good alternative to plastic related applications.

What is CRADLE TO CRADLE certification?

Our Stone Paper® products have been certified for its material content, recyclability, and manufacturing characteristics. http://www.c2ccertified.org/(licensed by C2CPII)

The Certification is a multi-attribute eco-label that assesses a product’s safety to humans and the environment and design for future life cycles. The program provides guidelines to help businesses implement the Cradle to Cradle framework, which focuses on using safe materials that can be disassembled and recycled as technical nutrients or composted as biological nutrients. Unlike single-attribute eco-labels, MBDC’s certification program takes a comprehensive approach to evaluating the design of a product and the practices employed in manufacturing the product. The materials and manufacturing practices of each product are assessed in five categories: Material Health, Material Reutilization, Renewable Energy Use, Water Stewardship, and Social Responsibility.

Is the technology patented with your company? If not who has the patent?

Intellectual properties for this revolutionary product are protected globally in major and emrging markets including Australia, Brazil, Canada, China, Europe, Taiwan, and USA.
Our Stone Paper® products are manufactured and supplied through a group of partners who have formed a confederation with sharing interest in the renewable mineral substrate technology.
Due to complex legal and taxation ramifications, a Taiwanese entity has been incorporated in the early 1990′s with heads consisting of the confederated member countries (Canada, Australia, Taiwan) to manage the modern technology, hold and maintain some of the relevant patents as well as oversee all production and manufacturing facilities.
