Abstract:
A processed edge face structure of a laminated film composed of two or more layers
comprising a uniaxially or biaxially stretched base film layer and a sealant
layer superposed on one side or each side of the base film layer, the structure
including one or more layers, e.g., an adhesive layer, an anchor coat layer, and
an ink layer, which have been completely prevented from being exposed. Also
provided are: a method of edge face processing for producing the structure; a
liquid ejection nozzle capable of preventing a filling to be packaged into a flexible
packaging bag from coming into contact with the adhesive layer, etc.; and a process
for producing the nozzle. The edge face of the laminated film comprising a base
film layer and sealant layers superposed thereon so that the base film layer is
sandwiched therebetween is characterized in that the edge face of the base film
layer has been covered with the sealant layers by disposing the sealant layers
so as to protrude from the edge of the base film layer.
