MULTI-LAYER STRUCTURE WITH POTASSIUM IONOMER

摘要

The present invention relates to a multi-layer structure constructed of two or more layers including a potassium ionomer layer (X) having a low surface resistivity and a layer (Y) comprising a polymer material having a high surface resistivity like LLDPE as a surface layer, where the static charge decay characteristics of the layer (Y) is improved. This type of two layer or three layer structure having the layer (X) as its intermediate layer or another surface layer gives good slip characteristics, abrasion resistance, and dust-free characteristics, and hence is useful for packaging materials, such as films, sheets and containers.
