Beautifully wrapped and gently protecting
Rengo offers a lineup of flexible packaging—including film packaging, cellophane, and molded packaging—which beautifully wraps products and gently protects products.
Film packaging
We are always searching for new applications to fulfill the basic functions of flexible packaging, and also provide proposals with enhancing product value in mind. We have a rich lineup—including flat bags, gusset bags, pillow bags, standing pouches, and pouches with zip fasteners—meeting product requirements.
Labels
Rengo offers shrink-on labels, roll labels, and roll-on shrink labels for bottles such as PET bottles and glass bottles.
Cellophane
This is a film with attractive gloss and high level of transparency. It is made by chemically processing wood pulp (cellulose) into a solution known as viscose which is then coagulated and regenerated. There are two types of cellophane: normal cellophane (PT) and white cellophane (PCW).
Rengo's cellophane is a biomass-derived transparent film made from wood pulp and has been certified as 95 percent biomass content and is eligible to display the biomass mark of the Japan Organics Recycling Association. It exhibits excellent biodegradability not just in soil, but in the ocean as well. The extremely high biodegradability of Rengo cellphone was confirmed by Organic Waste Systems (OWS), a Belgium-based measurement agency, through biodegradability testing in ocean water.
LossLess freshness preserving packaging
“LossLess” is a bag/film developed by Rengo that preserves the freshness of fruits and vegetables. It reduces the loss of freshness that is likely to occur during transportation and storage. It can be printed in the same way as regular film and delivered as both rolls and bags.

This is a film that uses biomass naphtha refined from biomass waste oil as part of its raw materials. It has the same physical benefits as our conventional products, and can be used while maintaining structure and performance.
ISCC PLUS Certification
International Sustainability & Carbon Certification (ISCC) is an international certification which conforms to EU guidelines for renewable energy. The certification is based on a mass balance approach, and Rengo is developing biomass polypropylene (PP) film that partially uses certified biomass materials.REBIOS Plastic Alternative Packaging
“REBIOS” is a series of packaging materials made from plant-derived, biodegradable cellophane and paper. It uses biodegradable biomass-derived materials in place of petroleum-derived plastic and has functions such as heat seal ability and moisture-proof property and acts as an oxygen barrier. The key features of REBIOS are high biomass content and biodegradability, and it can greatly reduce the amount of plastic used in packaging. It is suitable for packages used in a wide range of applications including foods, daily necessities, apparel, and sanitary materials.
Cellophane Based Packaging
Rengo offers an optimal material combination tailored to the products inside by leveraging transparency and printability of cellophane, and by widening the range of its heat sealing strength and barrier performance.
