Gunze introduces Purewrap thin film for frozen food packaging

Gunze, a manufacturer of plastic films and engineering plastics, has announced the launch of two new grades of its ultra-thin and robust Purewrap blown film.

The new additions include FS35NB and FS40NB, both of which are said to be suitable for boiling applications.

The new films are still ultra-thin yet robust and feature the properties of the Purewrap series. They are ideal for use in commercial kitchens and food processing plants.

FS35NB and FS40NB also improve sustainability by reducing plastic consumption by 50%.

This is in line with global efforts towards environmental sustainability and compliance with Japan’s Plastic Resource Circulation Act, which requires all stakeholders to reduce plastic consumption and improve resource recycling throughout the life cycle of plastic products.

Gunze has focused on perishable seafood, livestock and other products that are often transported in icy conditions.

The company launched Purewrap FS35N and FS40N in January 2022.

These films are said to be more than twice as puncture-resistant as conventional films while containing only half the plastic content.

With the introduction of the cookable variant, the company expanded the applicability of Purewrap to a wider range of foods processed in commercial kitchens and restaurants.

The Purewrap series, known for its co-extruded blown film with simultaneous biaxial orientation, offers unmatched puncture and impact resistance.

Gunze’s proprietary raw material blending, multi-layer construction and orientation technologies have resulted in a nylon-polyethylene film that is not only highly flexible but also extremely puncture resistant, making it well suited for refrigerated transport.

Gunze is headquartered in Osaka, Japan, has a presence in over 20 countries, and operates three manufacturing facilities in Japan and subsidiaries in the United States, China and Vietnam.
