Complete- degradable plastic film

Abstract

The invention discloses a totally degradable plastic film. The raw materials of the plastic film comprise high-density polyethylene or low-density polyethylene, middle-density polyethylene particles and fillers, adding with TDPATM additives which are produced by EPT company, Canada, and recovery connatural waste recycled plastic particles. The raw material and the weight ratio of the plastic film are 40 to 70 percent of the polyethylene particles, 2 to 30 percent of the TDPATM additives, 2 to 30 percent of the additives and 2 to 30 percent of the waste recycled plastic particles. 1 to 8 percent colored polyethylene particles are added in the raw materials to be made into colored film. The raw materials are mixed in proportion according to the production requirements, are added in an inflation film manufacturing machine to be heated up to the prescribed temperature and then the totally degradable plastic film is produced. The totally degradable plastic film has simple prescription, easy fabrication, few process steps, short flow and few used equipment with only the inflation film manufacturing machine. The thickness of the totally degradable plastic film can reach as thin as 0.02, with the middle; wherein, 0.025 thickness film has 33 MPa of longitudinal tension degree and 25 MPa of transverse tension degree of the mechanical properties, 260 percent of longitudinal tensile stretch and 620 percent of transverse tensile stretch and 3 months to 2 years of adjustable degradation time.

Description

technical field [0001] The invention relates to a plastic product, in particular to a completely degradable plastic film. Background technique [0002] As a material with a wide range of uses, plastic has greatly facilitated people's lives, but its non-decomposable characteristics have also caused serious environmental problems. Therefore, the research and production of degradable plastic products have attracted great attention internationally. People began to use starch and vegetable protein to produce a lot of research and development of degradable plastics, such as: Chinese patent application number: 200410065649.8, name: a high-starch degradable plastic film, made great achievements, but because of Production technology, production cost, product thickness and tensile strength and other reasons have not been promoted, and its application has also been greatly limited. Contents of the invention [0003] The technical problem to be solved by the present invention is to ...
