Outlet connection for a container

摘要

A sterile seal, especially for a food product container has a double layer plastic film fitted over the outlet port (3) and with the two layers (9, 11) bonded together and with the outer layer (9) scored (13). The seal ruptures along the score lines under pressure causing the inner seal to tear along the same score lines and without any risk of pieces of foil breaking off. The outer layer can be PET or PETP while the inner layer can be PE, LLDPE or PP. The score lines can be in a simple cross or as an open loop tag.
