Abstract
The film structure has a first exterior layer having a high-density polyethylene and an inorganic particle, a second exterior layer having a polyethylene-based material for sealing, and an interior layer having a high-density polyethylene, a nucleating agent and a hydrocarbon resin. The film may be use as a heat-sealable lid component for packaging and offers high moisture barrier, good heat resistance, and push-through and/or child-resistance performance while maintaining an overall composition acceptable for recycling.
Claims17
A lid packaging component comprising:
- a first exterior layer comprising a high-density polyethylene and an inorganic particle,
- a first interior layer comprising a high-density polyethylene, a nucleating agent and a hydrocarbon resin, and
- a second exterior layer comprising at least one of a polyethylene plastomer or an ethylene vinyl acetate copolymer wherein the lid packaging component has a heat seal initiation temperature of less than 130*C when the lid packaging component is sealed to high-density polyethylene under conditions of 0.5 seconds and 30 psi.
A lid packaging component comprising:
- a first exterior layer comprising a high-density polyethylene and an inorganic particle,
- a first interior layer comprising a high-density polyethylene and a hydrocarbon resin, and
- a second exterior layer, and
- wherein the first interior layer has a volume that is from 50% to 90% of the total volume of the lid packaging component, and
- wherein the lid packaging component has a heat seal initiation temperature of less than 130° C. when heat sealed to high-density polyethylene under conditions of 0.5 seconds and 30 psi.
A lid packaging component comprising:
- a first exterior layer comprising a high-density polyethylene and an inorganic particle,
- a first interior layer comprising a high-density polyethylene, a nucleating agent and a hydrocarbon resin, and
- a second exterior layer comprising a polyethylene-based material,
- wherein the lid packaging component has a heat seal initiation temperature of less than 130° C. when the lid packaging component is sealed to high-density polyethylene under conditions of 0.5 seconds and 30 psi.
