Osaka, Japan-headquartered Gunze Limited has debuted Purewrap, an ultra-thin and tough blown film specifically designed for food products requiring transportation in frozen environments. Two types have been introduced, FS35NB and FS40NB, each of which is compatible for boiling applications. Both retain the ultra-thin and tough characteristics that have defined the series to date, making them more convenient for use in industrial food processing facilities and central kitchens. They also contribute to environmental sustainability by cutting the use of plastic by approximately 50%.
Pinhole resistance can be maintained more than 2-3 times compared to conventional 70µm coextruded blown film thickness. Thickness is 35 micron and 39 micron, and there is compatibility
for boiling applications such as heat sterilization and hot water thawing of processed foods in food processing facilities.
The movement toward plastic reduction is gaining momentum 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, commercially prepared seafood such as filleted fish, red meat and other processed foods are often transported in frozen environments, where reducing plastic use is challenging due to concerns about strength loss from volume reduction. In Already 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 cutting plastic use by approximately 50%. This film type has been widely adopted by customers.
