YUPO manufacturing method

Proprietary manufacturing method
that has acquired many related patents in Japan and overseas

YUPO is a strong and flexible "film synthetic paper" developed by a proprietary manufacturing method.

YUPO was developed as a "dream paper alternative to general paper" for the purpose of "protecting forest resources".

The primary raw materials of YUPO are synthetic resin "polypropylene *" and natural mineral "inorganic filler". Wood pulp is not used as a raw material.

YUPO is manufactured from the above-mentioned primary raw materials with a small amount of additives, and as it is formed, micro-voids (tiny holes) are generated through a biaxial orienting film method.

Through this process, YUPO has the same characteristics of "water resistance and durability" as plastic films derived from the primary raw materials, but also has the suppleness, printability and suitability for handwriting of paper, thanks to the micro-voids.

This manufacturing method is based on our proprietary technology, and various patents related to YUPO have been issued in countries such as Japan, China, the United States, and Europe.

  • * Polypropylene is a general-purpose synthetic resin (plastic) consisting of hydrogen and carbon. It is a clean material that can be recycled in various ways and emits no harmful substances when burned.

Realization of strength
in the base layer and characteristics in the surface layer


Realization of strength
in the base layer and characteristics in the surface layer

YUPO is a three-layer synthetic paper
with a base layer laminated with a surface layer.

Light is irregularly reflected by countless micro-voids (tiny holes) generated in the surface layer during the stretching process, realizing high whiteness, printability, suitability for handwriting, and light weight, while strength is ensured by the base layer.

YUPO's various characteristics are obtained by combining this three-layer structure and technology (core technology), and there are hundreds of product variations including sheets with different thicknesses.

Tougher than paper, more expressive than film

YUPO is known for its water resistance, but this is not the only benefit.
It has many features not found in other synthetic paper, and its versatility is YUPO's greatest attraction.

Much more than paper...

Water resistant
Even if YUPO gets wet, there is virtually no reduction in its strength or deformation, providing it with excellent water resistance.
Tear resistant
YUPO is resistant to pulling, bending, and impact, and is far more tear resistant than paper. Laminated products with enhanced strength are also available.
Oil and chemical resistant
There is almost no deterioration in quality even when YUPO comes into contact with oils, acids, alkalis, or organic solvents.
Clean (low dust)
Dust generation is about 1/100 of high quality paper. There is almost no dust even when the sheet is bent or rubbed.
Light (cushioned)
Due to the special structure including micro-voids (tiny holes), the weight is about 2/3 of that of coated paper of the same thickness. YUPO is light enough to float in water.
The surface is smooth
Because the surface is very smooth, processes such as lamination result in a beautiful finish.

Much more than film...

Prints beautifully
You can print on YUPO in vibrant colors like paper and a wide range of printing methods are supported.
Suitable for handwriting
YUPO is not only compatible with oil-based pens, but also with pencils for some products. Smooth writing without catching or slippage.
Extensive product lineup
YUPO CORPORATION offers unique products such as adhesive products, translucent types, and metallic tones. There is also an extensive range of thickness variations.


synthetic paper that protects forests, water and air

Developed with the aim of replacing paper made of wood (pulp) with a new generation of paper,
YUPO contributes to environmental conservation and reduction of environmental impact in various ways.

Response to environment and safety

  1. YUPO and ALPHAYUPO do not use toxic substances or environmentally-harmful substances, such as heavy metals, asbestos, CFCs, halons, PCBs, PCTs, PBBs, phenols, formaldehyde, bromine flame retardants or plasticizers (phthalates), in the manufacturing process. In addition, the following substances, which are prohibited for manufacturing and import by Japanese law, are not used.
    Chemical Substances Control Law (Class 1 Specified Chemicals), Occupational Health and Safety Law (Substances Prohibited for Manufacturing), and Poisonous and Deleterious Substances Control Law (Specified Toxins).
  2. The above toxic substances and environmentally damaging substances are not used for YUPO manufacturing grade products, except for a portion of products.

YUPO is manufactured in factories that have acquired ISO14001 certification.

ISO14001 is an international standard for "Environmental Management Systems" that continuously improve the environmental impact caused by corporate activities.
Our KASHIMA FACTORY and research and development laboratory acquired this certification in March 2000. Based on our environmental policy, we work to save energy, recycle, reduce waste, and prevent pollution and accidents to contribute to the local community and the global environment.

Disposal of YUPO

If you have a large quantity of YUPO to dispose of ...
Once you have collected a certain quantity of YUPO to be discarded, such as used pamphlets, they can be reused as resources. Currently, YUPO is mainly used as recycled solid fuel (RDF and RPF) for reuse as heat energy, but recycling as plastic is also possible.
How to reuse collected YUPO
Non-contaminated YUPO, such as scraps cut at our factory, is melted down and used again as a raw material for YUPO. Wastes such as printed waste paper can be used as a raw material for recycled products such as flowerpots, nursery boxes, and piles.
How much thermal energy is generated during incineration?
YUPO can be processed in an incinerator and effectively used as heat energy. Its main uses are as an energy saving measure for heat sources in factory boilers, power generation, district heating and cooling, and heated water pools that use the generated heat.
Why can YUPO be incinerated as waste?
Plastics are said to have a high calorific value, which accelerates the damage of incinerators. YUPO has a blend of inorganic minerals as a filler, and has a calorific value of about 7,200 kcal/kg due to the micro-voids, about 2/3 that of ordinary plastics.
Moreover, the primary raw material of YUPO is a polyolefin made of carbon and hydrogen. When properly incinerated in a public incinerator, no harmful substances such as chlorine-based gas, unpleasant odor, or soot are generated.
How should I dispose of YUPO as garbage?
When disposing of YUPO as general household waste, please use your local government's plastic classification.
When disposing of YUPO as garbage at a business site, please dispose of it as industrial waste.
