1. About product launch

The movement of plastic-free society is accelerating not only in Japan but also in the world. After enforcing the "The Plastic Resource Circulation Act" in April, 2022, all stakeholders are required to promote resource recycling in all processes of plastic products, from designing products to disposing plastic waste.
The concept of “3R+Renewable” is getting popular and the reducing plastic usage has become an urgent matter. But fresh seafood, meat products and processed products are often transported in frozen environments, and there’s a pinhole accident happened during transportation process, that makes it difficult to reduce the amount of plastic usage by making the packaging film thinner.
Currently, non-oriented coextruded nylon blown film is widely used in food processing industry to protect the contents. But it has been required film thickness of 70 µm or over to maintain strength under refrigerated transport.
Gunze has newly developed "PUREWRAP FS35N & FS40N" with thicknesses of 35µm and 39µm and total weight of plastic usage in packaging can be reduced by approximately 50% compared to a conventional coextruded blown film thickness of 70µm. In addition, it has excellent pinhole resistance can be maintained at more than 2 to 3 times higher compared to a conventional coextruded blown film thickness of 70µm.

2. Recommended Applications

The company recommends the use of the product for all food products that need to be transported in a frozen environment.
