Package, particularly for aseptically packageable products

Abstract

A package ( 10 ), particularly for aseptic packaging, is made up of two opposite facing walls ( 12 ) heat sealed one to the other along a peripheral line (S). The walls ( 12 ) include at least one layer in metallized heat-sealable plastic material ( 13 ) or with barrier effect and at least one layer ( 16 ) in heat-sealable plastic material. The peripheral heat sealing line (S) is provided at the cutting edge of the walls ( 12 ) so as to form an encapsulation (I) of the coupled layers ( 13, 16 ) at the cutting edge, due to overflow of the plastic material.
