About product launch

The movement toward a plastic-free society is gaining momentum not only in Japan, but around the world. With the implementation of the “Plastic Resource Circulation Act” in Japan in April 2022, all stakeholders are now required to reduce plastic use and promote resource recycling throughout the entire lifecycle of plastic products, from design to waste disposal.

In particular, perishable seafood, livestock products, and their processed forms are often transported in freezing environments, where reducing plastic use is challenging due to concerns about strength loss from volume reduction. In January 2022, Gunze introduced Purewrap FS35N and FS40N, which offer more than twice the puncture strength of conventional non-oriented nylon-polyethylene 70 µm films while reducing plastic use by approximately 50%. This film type has been widely adopted by customers. It has now been renewed as a boilable type, expanding its applicability to a wider range of foods processed in central kitchens for commercial prepared foods and restaurants.

[Recommended Applications]

The company recommends the product for food applications that require transportation in frozen environments and processing in central kitchens.
