Embodiment 1

[0035] Biodegradable plastics are composed of polymer materials, biodegradable masterbatches with starch as the main component, and auxiliary materials after mixing.

[0036] The polymer material here is one of polyethylene, medium-density polyethylene, high-density polyethylene, polypropylene, and the like.

[0037] Here, the biodegradable masterbatch with starch as the main component adopts graft-modified starch: lipophilic molecules are grafted on the main chain of starch molecules, and are compatible, dispersed, and plasticized with the carrier resin, so that the obtained biodegradable Degradable masterbatch has the characteristics of plastic itself.

[0038] The auxiliary materials here include elastomers, linear low-density polyethylene, etc.

Embodiment 2

[0040] The biodegradable plastic as in Example 1, but the auxiliary materials can also include any one or several of auxiliary agents such as lubricants and plasticizers.

Embodiment 3

[0042] The biodegradable plastics as in Examples 1 and 2, but the biodegradable masterbatch is the biodegradable masterbatch produced by Shanghai Linda Plastic Chemical Co., Ltd. and the brand is S 1212.

Abstract

A biodegradable plastic container is prepared from the biodegradable basic material (high-density polyethene or starch), elastomer, and linear low-density polyethene through proportionally mixing, and blow moulding. Its advantages are environmental protection and high compression strength and impact strength.
