Title:
COMPOSITION CONTAINING CARBON-REDUCTION TYPE BIOMASS POLYETHYLENE FOR STRETCH FILM AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2019/107626
Kind Code:
A1
Abstract:
The present invention relates to a composition for a carbon-reduction type biomass stretch film having high strength and high stretchability, and to a method for preparation the same and, more specifically, to a carbon-reduction type biomass stretch film, which has excellent tensile strength, leading to reductions in packaging weight and volume, thereby reducing logistic costs; is environmentally friendly due to a carbon dioxide reduction effect; and has improved tensile strength and stretching rates so as to be used for packaging by stretch films, by resolving the problems of conventional biomass-containing films, that is, the disadvantages that films are difficult to distribute for a long period of time due to weakness to heat and too fast biodegradation thereof, through a bio polyethylene resin containing biomass derived from a natural material, such as sugarcane, a linear low-density polyethylene resin obtained by polymerization under a Ziegler-Natta catalyst, and a linear low-density polyethylene resin obtained by polymerization under a metallocene catalyst, and the polymer matrix design.
