Embodiment 1

[0018] The transparent high-impact polyethylene film of the invention is formed by blowing 60wt% polyethylene and 40wt% metallocene polyethylene through a three-layer co-extrusion blow molding machine.

[0019] Among them, polyethylene is HDPE; the processing conditions of the three-layer co-extrusion blow molding machine are die head temperature 170°C, die neck temperature 165°C, and the temperature of each processing area, processing area and flow channel is 130-145°C.

Embodiment 2

[0021] The transparent high-impact polyethylene film of the invention is formed by blowing 95 wt% polyethylene and 5 wt% metallocene polyethylene through a three-layer co-extrusion blow molding machine.

[0022] Among them, the polyethylene is LLDPE; the processing conditions of the three-layer co-extrusion blow molding machine are the die temperature of 170°C, the die neck temperature of 165°C, and the temperatures of each processing area and the processing area and flow channel are 130-145°C.

Embodiment 3

[0024] The transparent high-impact polyethylene film of the invention is formed by blowing 80 wt% polyethylene and 20 wt% metallocene polyethylene through a three-layer co-extrusion blow molding machine.

[0025] Among them, polyethylene is a mixture of LDPE and LLDPE; the processing conditions of the three-layer co-extrusion blow molding machine are die head temperature 170°C, die neck temperature 165°C, and the temperature of each processing area, processing area and flow channel is 130-145°C.

Abstract

The invention discloses a high-impact transparent polyethylene film. The high-impact transparent polyethylene film is prepared by performing blow molding on 60-95 percent by weight of polyethylene and 40-5 percent by weight of metallocene polyethylene by virtue of a three-layer co-extrusion blow molding machine. The high-impact transparent polyethylene film is high in friction coefficient, high in heat seal strength, high in transparency, high in impact resistance and high in tensile property.

Description

technical field [0001] The invention belongs to the technical field of polymer materials and relates to a transparent high-impact polyethylene film. Background technique [0002] Polyethylene is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of olefins. Polyethylene accounts for 70% of the world's consumption of polyolefins and 44% of the consumption of thermoplastic general-purpose plastics. Polyethylene is basically divided into three categories, namely low density polyethylene (LDPE), high density polyethylene (HDPE) and linear low density polyethylene (LLDPE). [0003] Metallocene polyethylene (m-PE) is a new type of thermoplastic, which is the most important technological progress in the polyolefin industry in the 1990s and an important innovation after the production technology of LLDPE. Metallocene polymers are only 20 years old. In 1991, Exxon synthesized metallocene polyethyle...
