Abstract
The present invention relates to a tubular film intended to form a stretch hood. The tubular film has a core layer and at least one skin layer. The core layer comprises, by weight of the core layer: 30-80% of recycled polyethylene; 10-35% of a polymer booster selected from a thermoplastic elastomer and a polyolefin plastomer; and 0-40% of virgin ethylene polymer and/or virgin ethylene based copolymer.
Claims16
A tubular film adapted to form a stretch hood, the tubular film having a core layer and at least one skin layer, wherein the core layer consists of, by weight of the core layer:
- 30-80% or recycled polyethylene, wherein the recycled polyethylene has a density of less than 0.930 g/cm3;
- 10-35% of a polymer booster that is a thermoplastic elastomer, wherein the thermoplastic elastomer has a density of less than 0.900 g/cm3;
- 0-40% of virgin polymer and/or virgin ethylene based copolymer, and wherein the virgin ethylene polymer and/or virgin ethylene based copolymer are selected from the group consisting of low density polyethylene (LDPE), very low density polyethylene, linear low density polyethylene, styrene butadiene copolymer, ethylene-vinyl acetate copolymers (EVA), and ethylene butyl acrylate copolymers (EBA), and
- the at least one skin layer has a lower flexibility than the core layer.
