Frequently Asked Questions
Inquiries about features of YUPO
How does synthetic paper differ from conventional paper (general paper)?
Whereas conventional paper (general paper) is made primarily from wood pulp, most synthetic paper is manufactured from oil-based synthetic resins (plastics). As a result, synthetic paper possesses characteristics resembling those of plastic film, but looks almost indistinguishable from regular paper. Synthetic paper outperforms regular paper in terms of moisture resistance (almost no structural deterioration or deformation when wet) and durability (resistance to tearing). In addition, it is resistant to chemicals and oils, and has an exceptionally smooth surface finish.
What is YUPO?
"YUPO" is a registered trademark of YUPO CORPORATION, and is a brand name covering the entire line of synthetic paper products manufactured by our company.
The idea for the name "YUPO" came from using the "P" from "paper" to connect the "YU" from our parent company Mitsubishi Yuka (present Mitsubishi Chemical Corporation) and the "O" from our parent company Oji Paper Company (present Oji Holdings Corporation).
- *When using the YUPO name, please refer to our trademark usage guidelines.
What is the YUPO "smell"?
YUPO is synthetic paper with almost no smell. YUPO printed matter made with oil-based offset printing and YUPO ink has a pungent odor, which comes from the vegetable oil-derived YUPO ink. For applications in which smell is an issue, use PP or PET lamination on the printing surface.
Is YUPO hygienic for food use?
YUPO and ALPHAYUPO QJJ grade conform with the containers and packaging for foods (alcohol, fats and other general foods), excluding acidic foods with a pH of 5 and below, as described in the Japanese Ministry of Health and Welfare Announcement No. 370 (1959).
- The safety of applications for foods has not been verified for YUPO processed goods or ALPHAYUPO, so avoid uses in which they come into direct contact with food.
However, as our company's manufacturing process itself is not in conformance with the hygiene standards stipulated in FSSC 22000, enact sanitation measures at the printing and processing stages when using YUPO for food utensils, containers, and packaging.
How do I dispose of YUPO?
While YUPO does not release toxic substances when incinerated, please follow your local municipality's guidelines for plastic categories when disposing of it as household waste. For commercial disposal, YUPO must be treated as industrial waste. Also, see information here.
About YUPO's bitterness
Some persons may experience bitterness if tasting YUPO or ALPHAYUPO. This bitterness results from the chemical agents used in YUPO surface treatment, and, as noted above, is safe and harmless to humans. To avoid effects of bitterness in food packaging, etc., use film lamination.
As YUPO is not a food, do not eat or lick the products.
Is YUPO recyclable?
Yes. YUPO is mainly made from polypropylene (PP), a material with outstanding recyclability, and can be recycled in a variety of ways. As it is made from the same polyolefin resin used for shampoo bottles and the like, YUPO labels can be recycled without having to be peeled off the bottle. Once melted down and molded, the material can be reused in recycled products such as plastic flower pots and pegs.
Can YUPO be used with photocopiers in offices or convenience stores?
No. Exposure to the high temperatures generated by conventional copy machines or laser printers can result in deformation of YUPO and unexpected problems. However, there are laser printer models for production that can be used with YUPO. Please inquire for details.
