UNILAX LS grade

L-LDPE film for laminating

Idemitsu's special L-LDPE ensures both good sealability and tough film strength. This product is applicable for a wide range of applications from low-temperature heating to semi-retort thanks to distinctive multilayer technology. Furthermore, all grades are designed to be applicable to non-powder laminating and bag making.
