Abstract

The invention relates to a biodegradable adhesive sticker label. The biodegradable adhesive sticker label comprises a surface material layer, an adhesive layer and backing paper, wherein the adhesive layer is positioned between the surface material layer and the backing paper, the backing paper adopts silicone oil-coated glassine paper, and the surface material layer comprises the following compositions in part by weight: 30-70 parts of PHA, 0-150 parts of polylactic acid, 0-50 parts of starch, 1-15 parts of plasticizer, 0.3-1 part of nucleating agent, and 1-10 parts of lubricating agent; the adhesive layer comprises the following compositions in part by weight: 20-60 parts of starch, 90-110 parts of water, 5-50 parts of PHA, 0.5-20 parts of alkaline matters, 0.5-10 parts of water-proofing agent, 0.1-5 parts of crosslinking agent, and 0.1-5 parts of bacteriostatic agent. Complete biodegradation can be realized without compost treatment; the adhesive sticker label has better mechanical property according to weight part proportion of all compositions, and the viscosity, the water resistance and the binding strength of oxidized starch can be effectively regulated and improved. In addition, the label has the characteristics of being simple in structure, simple and convenient in preparation process, and low in cost.

Description

technical field

[0001] The invention relates to a self-adhesive label, in particular to a biodegradable self-adhesive label. Background technique

[0002] Self-adhesive labels are mostly made of paper, film or special materials as the fabric, coated with adhesive on the back, and a composite material coated with silicon-coated backing paper as the protective paper. At present, the self-adhesive label industry has maintained rapid growth for many years, but the non-degradable and difficult to recycle of these materials have caused enormous pressure on the environment.

[0003] Publication number CN101602921A, a patent application published on December 16, 2009, discloses an environmentally friendly hot-melt self-adhesive material and its preparation method. This environmentally friendly hot-melt self-adhesive material uses glassine paper as the base paper , treated with a solvent-free solution, coated with glue on the surface of the surface material, the glue is 100% solid c...
