LAMINATE MATERIAL FOR PAPER CONTAINERS AND PAPER CONTAINERS FOR LIQUIDS

摘要

A laminate material for paper containers and paper containers for liquids which are mainly employed in storing retort-packed liquid foods. In the laminate material (10) for paper containers, a cushioning layer (12), a barrier layer (13) and a sealant layer (14) are successively laminated on one face of a hot waterproof paper (11). In the case of folding the laminate material (10) in the process of forming a paper container (20) for liquids by molding, the cushioning layer serves as a cushioning and thus pinholing can be prevented.
