Laminate sheeting for pouches

摘要

A pouch or other container for forming an envelope protectively packaging a product such as a flowable or solid food substance. The pouch is fabricated from a laminate sheeting whose plies have different properties that depend on package requirements, at least one ply in the laminate being an oriented, synthetic plastic film of high tensile strength. The plies are adhesively interlaminated at ambient temperature with a water-based adhesive whereby the orientation of the film is unaffected by the laminating process, in the course of which no environmentally objectionable fumes are discharged into the atmosphere. The laminate may also be made into a water-resistant envelope or package for mailing various materials.
