摘要:
Disclosed herein is a container featuring at least one hole, and process for making the same. The container is prepared from a sheet-like composite having (i) a polymer outer layer facing the surroundings; (ii) a carrier layer following the polymer outer layer in the direction of the container interior; (iii) a barrier layer following the carrier layer in the direction of the container interior; (iv) an adhesive layer following the barrier layer in the direction of the container interior; and (v) a polymer inner layer following the adhesive layer in the direction of the container interior. The sheet-like composite is prepared by laminating the individual layers, wherein at least the polymer inner layer or the adhesive layer are stretched during application.
