Japan Unisaki developed a nylon film for high barrier food packaging

Japan Unisaki Card Co., Ltd. has developed a transparent nylon film for food packaging that combines high gas barrier properties, bending resistance, and scratch resistance. At present, the film has a market share of 10% in the field of cooking food packaging.

In the field of food packaging, due to the growing demand for steamed foods, the demand for transparent film packaging materials with high gas barrier properties has also increased. In addition, the transparent film used in liquid packaging and shopping malls for food packaging is made of a nylon material that is resistant to permeation. However, after this film material has been retort-sterilized, it has a problem of reduced gas barrier properties, which limits the scope of use of the material. . Therefore, there is a need for a nylon film packaging material that does not degrade the gas barrier properties after heating and sterilizing treatment and can store food for a longer period of time.

The film developed this time adopts a proprietary coating technology, achieving high gas barrier performance under high humidity (high oxygen barrier performance) 2 high gas barrier property after retorting treatment 3 bending resistance and scratch resistance 4 High transparency 5 Excellent printability.
