Oxygen and flavor barrier laminate for liquid packaging

摘要

A heat-sealable paperboard laminate for liquid packaging which does not transmit nor absorb oxygen or flavor and odor ingredients comprises paperboard sandwiched between two layers of heat-sealable low density polyethylene polymer (LDPE) and including a three-component product-contact barrier layer coextruded onto the inner layer of LDPE. The barrier layer comprises ethylene vinyl alcohol copolymer (EVOH)/a tie layer (Plexar 177 or 175)/ low density polyethylene polymer (LDPE).
