Development of a packaging material using non‐bleed‐type antistatic ionomer

Abstract

AbstractGenerally, plastics and plastic films are low in moisture absorption and high in electric insulation. They are inherently vulnerable to static charge build‐up, which can result in a variety of problems. We have developed a functional packaging material to solve these static problems, by using a potassium salt of ethylene ionomer, which is a non‐bleed‐type antistatic agent. Good antistatic performance was shown by evaluating a variety of electric characteristics (e.g. the static decay time, ash test and saturated electrostatic charge and half‐life) and surface resistivity. In addition, antistatic performance was achieved on the mLLDPE (non‐treated) side in a multilayer structure. This means that the use of potassium ionomer on any layers in a multilayer structure provides antistatic performance, leading to the expectation of developing a wide variety and diversity of packaging materials.
