Abstract

The invention discloses a degradable composite tourist commodity packaging film, which comprises the following components in parts by weight: 12 to 16 parts of phenylhydrazine hydrochloride, 5 to 8 parts of 2-amino-5-chloropyrazine, 4 to 8 parts of S-benzylthiourea hydrochloride, 3 to 6 parts of 3-cyano-5-fluoro-borophenylic acid, 4 to 6 parts of 2-bromo-3-nitrotoluene, 11 to 15 parts of 3-amino-2, 2-dimethyl acrylamide, 10 to 16 parts of acetylated konjac glucomannan, 7 to 10 parts of p-cresyl benzyl acetate, 2 to 5 parts of tetraethyl orthosilicate and 6 to 10 parts of diphenyl phosphate. The invention also discloses a preparation method of the degradable composite tourist commodity packaging film. According to the invention, the defects of the prior art can be solved and the degradation speed of the film is increased.

Description

technical field [0001] The invention relates to a degradable film production process, in particular to a degradable composite film for tourism commodity packaging and a preparation method thereof. Background technique [0002] All kinds of tourist souvenirs sold now are generally packaged with plastic film. If ordinary plastic film is not recycled professionally, it will form white pollution. Therefore, more and more packaging films are now made of degradable materials. Chinese invention patent CN 1138820C discloses a method for preparing a degradable enhanced packaging film, using konjac fine powder to make a degradable film. According to the experiment of the inventor, the degradation speed of this degradable film is relatively slow. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a degradable composite film for tourism commodity packaging, which can solve the deficiencies of the prior art and improve the de...
