PEVA film for laundry basket and preparation method for PEVA film

Abstract

The invention relates to the technical field of film materials, in particular to a PEVA film for a laundry basket and a preparation method for the PEVA film. The PEVA film comprises the following components in parts by weight: 20-50 parts of EVA resin, 10-40 parts of PE resin, 20-50 parts of MPE resin, 0-10 parts of EVA color master batch, 1.0-2.0 parts of a fluoropolymer additive and 0-5 parts of other additive. The MPE resin is metallocene-linear polyethylene. The other additive is an ultraviolet stabilizer or an antioxidant. The preparation method comprises the following steps of: 1) weighing the raw materials at the weight part ratio of the components of the PEVA film for the laundry basket, pouring the EVA resin, the PE resin, the MPE resin, the EVA color master batch, the fluoropolymer additive and the other additive into a high-speed mixer for stirring and mixing uniformly, then performing blending melting and extrusion through a casting machine, and performing tape-casting through a flat die head to obtain a semi-finished PEVA film; and 2) performing embossing cooling forming on the semi-finished PEVA film in a molten state in the step 1) to obtain the finished PEVA film. The finished PEVA film for the laundry basket is 0.10-0.50 mm in thickness.

There are many types of laundry baskets, including plastic ones, metal tubes and canvas ones, bamboo weaving ones, rattan weaving ones, wooden ones, etc. These laundry baskets are mostly independent individuals, which generally have problems such as large size and inconvenient storage; and Laundry baskets made of metal tubes and canvas are not easy to recycle, the canvas needs to be dyed by a dyeing factory, and it is not environmentally friendly.

[0003] Polyethylene-vinyl acetate, referred to as PEVA, is a blend of PE and EVA. It has good softness and a little elasticity. It is one of the commonly used materials for making films. Although the PEVA film made of this material has Good toughness, but insufficient tensile strength, the product is prone to scratches
