DUST-FREE PACKAGING BAG EXCELLENT IN AUTOMATIC PACKAGING SUITABILITY

摘要

PROBLEM TO BE SOLVED: To provide a dust-free packaging bag for packaging electronic material parts or the like that requires high cleanness, while improving suitability for automatic packaging using an automatic packaging machine.SOLUTION: In a dust-free packaging bag for packaging electronic parts or the like, having at least a sealant layer 2 as an innermost layer, uses a polyester film with a gloss value of 40-130% as an outermost layer film 4, and forms a primer layer or an adhesive layer including an antistatic agent in a substrate layer 3 or on the innermost face. A peak value of an initial charged voltage in a friction voltage pressure test of the surface of the outermost layer film 4 is ≤2.0 kV by absolute value.
