For greater stretchability and shrinkability: New grade of gas barrier resin from Kuraray

With today’s material manufacturers being called upon to develop products with stronger emphasis on eco-friendliness, gas barrier packaging materials are garnering rising public interest as a means of addressing issues arising from plastic waste as well as food loss problems. In response, Kuraray developed EVAL SC series, building on the success of EVAL, which enjoys widespread use in food packaging materials thanks to its superior gas barrier property, a property that contributes to the long-term preservation of food and thus reduces food loss. Through the marketing of EVAL SC boasting new features supporting the design of innovative food packaging materials, Kuraray will contribute to further reduction in the volume of packaging materials and thereby help curb the environmental burden arising from such materials.

Features of EVAL SC

・While it maintains gas barrier property comparable, or even superior, to that of conventional EVOH products, EVAL SC boasts greater stretchability and shrinkability.

・Used in combination with polyethylene and other olefin-based materials to form a multilayer structure, EVAL SC provides better support for biaxially oriented multilayer films for food packaging use, including shrink bags and skin packaging materials.

・The release of EVAL SC is therefore expected to accelerate Kuraray’s development of applications and markets for its gas barrier packaging materials. For example, Kuraray intends to propose its use as an alternative meat packing material to replace polyvinylidene chloride (PVDC).

Potential Applications

Shrink bags, skin packaging materials and other food packaging materials
