EDGE FACE STRUCTURE OF LAMINATED FILM, METHOD OF PROCESSING EDGE FACE, LIQUID EJECTION NOZZLE WITH PROCESSED EDGE FACE, AND PROCESS FOR PRODUCING THE SAME

摘要

The invention is to provide an end face treating structure completely preventing exposure of adhesive layer, anchor coating layer, ink layer and the like at an end face of a laminate film of two or more layers comprising at least uniaxially or biaxially oriented base film layer and a sealant layer laminated on one-side face or sandwiching the base film layer and a process for treating an end face as well as a liquid pouring nozzle capable of preventing contact of a packing material in a soft package bag with the above adhesive layer and the like and a method of producing the same. The construction lies in a point that in the end face of the laminate film comprising the base film layer and sealant layers laminated sandwiching it, the sealant layers are protruded from the edge of the base film layer to cover the end face of the base film layer.
