Heat-sealable Paperboard

Heat-sealable paperboard containers comprised of various laminate structures are widely used in the container industry. A growing concern regarding the solid waste disposal of containers coated on two sides with non-degradable pol5mciers has arisen, and a solution to the non-readily biodegradable container has been widely sought (16). [Pg.203]

A low temperature extrusion coatable grade heat-sealable biodegradable pol5mrer resin is thermoplastic poly(vinyl alcohol) resin or starch-based low density poly(ethylene) pol5mer resin. [Pg.203]

The structure from exterior layer to interior food contact layer is as follows (16)  [Pg.203]

A heat-sealable gloss layer of a degradable polymeric resin, preferably a starch-based poly(ethylene) (PE) resin or a PYA alcohol resin [Pg.203]

An interior adhesive tie layer, preferably an ethylene based copolymer with grafted functional groups [Pg.204]

Poly(vinyl acetate) emulsions and resins have been used as the binder in coatings for paper and paperboard since 1955. The coatings may be clear, colored, or pigmented, and are glossy, odorless, tasteless, grease-proof, nonyellowing, and heat-sealable. Conventional paper-coating equipment is used... [Pg.1678]
