Embodiment 1

[0013] A high-strength environmentally friendly plastic bag for packaging, comprising the following components in parts by weight: 15 parts of low-density polyethylene, 10 parts of acrylic resin, 10 parts of plant starch, 20 parts of plant straw, 10 parts of calcium carbonate whiskers, 10 parts of filler, 5 parts of polypropylene compatibilizer, 3 parts of silane coupling agent, and 0.1 part of photosensitizer. Wherein, the plant starch is a mixture of corn starch, potato starch and tapioca starch in a mass ratio of 3:2:1; the plant straw is a mixture of corn straw and rice straw in a mass ratio of 1:3; the The filler is a mixture of wood flour, pottery clay and montmorillonite in a mass ratio of 2:1:1.

Embodiment 2

[0015] A high-strength environmentally friendly plastic bag for packaging, comprising the following components in parts by weight: 20 parts of low-density polyethylene, 15 parts of acrylic resin, 20 parts of plant starch, 30 parts of plant straw, 20 parts of calcium carbonate whiskers, 20 parts of filler, 8 parts of polypropylene compatibilizer, 5 parts of silane coupling agent, and 0.5 parts of photosensitizer. Wherein, the plant starch is a mixture of corn starch, potato starch and tapioca starch in a mass ratio of 5:3:1; the plant stalk is a mixture of corn stalk and rice straw in a mass ratio of 2:5; the The filler is a mixture of wood flour, pottery clay and montmorillonite in a mass ratio of 3:2:1.

[0016] The tensile strength of the above-mentioned plastic bags is 5-8 MPa, and the elongation at break is 10-20%. In addition, due to the use of calcium carbonate whiskers, the plastic bags are also endowed with excellent shockproof performance. The packaging bag of the pr...

Abstract

The invention discloses a high-strength green plastic bag used for packaging. The plastic bag comprises: by weight, 15-20 parts of low density polyethylene, 10-15 parts of acrylic resin, 10-20 parts of plant starch, 20-30 parts of plant straw, 10-20 parts of calcium carbonate whisker, 10-20 parts of filler, 5-8 parts of polypropylene compatilizer, 3-5 parts of silane coupling agent, and 0.1-0.5 part of photosensitizer. The tensile strength of the plastic bag is 5-8 MPa, the breaking elongation is 10-20%, and the degradation rate is more than 90%. The high-strength green plastic bag used for packaging has good structural strength and shake-proof performance after scientific and reasonable formulation design, protects the packaged material in an all-round manner, has biodegradation and photodegradation performances, reduces the environmental pollution effectively, and is a green packaging plastic bag with good comprehensive performance.

Description

technical field [0001] The invention relates to the field of plastic bags for packaging, in particular to a high-strength environment-friendly plastic bag for packaging. Background technique [0002] Plastic bags are widely used because of their cheapness, light weight, and easy storage, and they have always occupied an important position in people's lives. However, because the traditional plastic bags cannot be degraded, they will seriously pollute the environment after being used and discarded, which greatly limits their use. At present, there are a large number of degradable plastic bags on the market, but most of them have low strength and cannot meet the requirements of use. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a high-strength environment-friendly plastic bag for packaging, which can solve the above-mentioned problems existing in the existing plastic bags. [0004] In order to solve the above t...
