BEUTEL FÜR NAHRUNGSMITTEL, VERFAHREN ZUM VERPACKEN UND VERWENDUNG EINES MEHRSCHICHTFILMS FÜR BEUTEL

摘要

The present invention provides a bag for packaging food products whose materials can be easily recycled. A bag for packaging food products is formed of a laminated film having a structure of polyester-type sealant layer with a low melting point / barrier layer (vapor-deposited layer of ceramic or metal)/ polyester-type heat resistant layer with a high melting point. The bag is formed by heat sealing the film such that the polyester-type low melting point sealant layer forms an inner side.
