Abstract

The invention discloses a modified plastic stretch canvas and a preparation method thereof. The modified plastic stretch canvas includes a modified plastic layer, one side of the modified plastic layer is provided with a canvas layer, and the other side of the modified plastic layer is provided with a LDPE foaming material layer. The modified plastic stretch canvas has the advantages of being light in weight, waterproof, and good in toughness, tensile strength and tear resistance, and can disperse external impact force to achieve the effect of buffering and damping.

Description

technical field [0001] The invention relates to the field of cushioning and environment-friendly packaging materials, in particular to a modified plastic casting canvas and a preparation method thereof. Background technique [0002] At present, the foam material EPS (Expanded Polystyrene) on the market has the disadvantages of fragility, deformation, and poor recovery when used. It cannot be recycled after use, causing environmental pollution and is not environmentally friendly. The market will become smaller and smaller; It has the advantages of environmental protection, easy cutting, low cost, and wide application range. However, due to its hard surface, it will cause wear and scratches on the surface of some products, and it is difficult to form three-dimensional processed products, and it has high humidity, water absorption, and poor overload recovery. , so it is slightly inferior in cushioning packaging materials. Especially in fruit, fragile and easily scratched produ...
