Abstract

The invention relates to a preparation method of a self-adhesive and degradable disposable tablecloth. The self-adhesive and degradable disposable tablecloth comprises an adhesive layer, an inner layer and an outer layer and is composed of components including C6LLDPE (carbon 6 linear low-density polyethylene), mLLDPE (metallocene linear low-density polyethylene), PIB (polyisobutylene), starch, polylactic acid, glycerinum, bulking agent, soy protein, C8LLDPE, LDPE (low-density polyethylene), cycloolefin, anti-blocking agent and calcium carbonate. The self-adhesive and degradable disposable tablecloth prepared through the preparation method has the advantages of being non-toxic, environmentally friendly, pollution-free, light in weight, low in water absorption, high in breaking elongation,biologically degradable and free from recycling.

Description

technical field [0001] The invention relates to a disposable tablecloth, in particular to a method for preparing a self-adhesive and degradable disposable tablecloth. Background technique [0002] Disposable tablecloths are commonly used daily necessities, especially disposable tablecloths. Disposable tablecloths have won the trust of many consumers because of their convenience and speed. Disposable tablecloths need to sprinkle some water on the tabletop when using them, and tie the four corners of the disposable tablecloth tightly, which will affect the appearance. Because the quality of dining tables is getting higher and higher now, many families generally do not use tablecloths. When visitors come, they simply spread a layer of disposable paper tablecloths and throw them away after use. Although simple, it has brought huge environmental pollution. It is a problem to be solved by those skilled in the art to develop a kind of windproof, comfortable and disposable tablecl...
