Abstract

See full text

A composite container is provided for holding products (e.g., stacked chips). The container includes a tubular body and a peelable membrane. The tubular body is made of at least one paperboard body ply having an inner surface and a metallized Oriented Polypropylene (mOPP) liner ply adhered to the inner surface of the paperboard body ply. A liner sealant is disposed on the inner surface of the mOPP liner ply, and the paperboard body ply and the mOPP liner ply are rolled outwardly to form a rim. The membrane, which has a membrane sealant on its inner surface, is sealed to the liner sealant in the area of the rim to close the container. When the membrane is peeled away, the membrane sealant and the liner sealant remain sealed to each other and cause separation within the mOPP liner ply, avoiding tearing and exposure of the paperboard in the rim.
