Abstract
Disclosed herein are compositions and methods related to a packaging laminate comprising: a first polymeric layer comprising a polypropylene copolymer or a high density polyethylene (HDPE) resin; and a second polymeric layer comprising a high density polyethylene (HDPE) resin or linear low density polyethylene (LLDPE) resin with a coextruded ethyl vinyl alcohol (EVOH) compatibilizer. Also disclosed herein are packaging containers formed of the packaging laminates.
Claims20
A packaging container, comprising:
- a container body formed of a packaging laminate, wherein the packaging laminate comprises:
- a first layer formed from a first composition comprising a high density polyethylene (HDPE) resin and constituting an outer layer of the packaging laminate;
- and
- a second layer formed from a second composition comprising a linear low density polyethylene (LLDPE) resin, low density polyethylene (LDPE), ethyl vinyl alcohol (EVOH), and a EVOH compatibilizer and constituting an inner layer of the packaging laminate;
- and
- a one-way degassing valve removably attached to the container body, wherein the one-way degassing valve comprises a filter for releasing volatile gases present within the container body and is formed of a polymeric material comprising HDPE, LDPE, medium density polyethylene (MDPE), and combinations thereof.
