Abstract

PURPOSE: To prepare the captioned film for buffer packaging useful for protecting the contents from shock by conducting a specific treatment to the foamed resin layer of the film having a foamed resin layer and a non-foamed resin layer.
CONSTITUTION: On the foamed and non-foamed resin layers, foams of the foamed resin layer of an extruding inflation film are flattened by stretching orientation and part or all of these foams are burst to form a network structure. Fine crinkles are produced all over the laminated film and the apparent bulk of the film is swollen by reheating and shrinking the laminated film.
