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 recyclable packaging container formed of a packaging laminate, the packaging laminate comprising:
- a first layer, constituting an outer layer of the packaging laminate, formed from a first composition consisting of a high density polyethylene (HDPE) resin;
- a second layer, constituting an inner layer of the packaging laminate, formed from a second composition comprising a linear low density polyethylene (LLDPE) resin, ethyl vinyl alcohol, a compatibilizer, and a catalyst.
A recyclable packaging container, comprising:
- a container body formed of a packaging laminate, wherein the packaging laminate comprises:
- a print layer formed from a first composition and constituting an outer layer of the packaging laminate, wherein the first composition consists of a high density polyethylene (HDPE) resin;
- a core layer formed from a second composition and constituting an intermediate layer of the packaging laminate, wherein the second composition comprises a HDPE resin, a linear low density polyethylene (LLDPE) resin, a low density polyethylene (LDPE) resin, or combinations thereof;
- and
- a sealant layer formed from a third composition and constituting an inner layer of the packaging laminate, wherein the third composition comprises a LLDPE resin, ethyl vinyl alcohol (EVOH), a compatibilizer, and a plastomer, and
- a degassing valve removably attached to a wall of the container body.
A recyclable packaging laminate comprising:
- an outer layer comprising a first composition, wherein the first composition consists of a high density polyethylene (HDPE) resin;
- an intermediate layer comprising a second composition, wherein the second composition comprises a linear low density polyethylene (LLDPE) resin;
- and
- a sealant layer comprising a third composition and constituting an inner layer of the packaging laminate, comprising a LLDPE resin, ethyl vinyl alcohol (EVOH), and a compatibilizer, wherein the compatibilizer and EVOH are present in the third composition in a 1:1 ratio.
