Abstract

The invention discloses a plant fiber foaming packaging material. According to the packaging material, a density is 0.23-0.28g / cm<3> and a yield limit is within 850-1000N / cm<2>. The packaging material comprises the following components in parts by weight: 100 parts of plant fiber, 35-37 parts of corn starch, 2-4 parts of sodium carboxymethylcellulose, 1-2 parts of polyoxyethylene, 6-8 parts of wollastonite in powder, 12-14 parts of talcum powder, 6-8 parts of plant fiber modifier, 2-4 parts of organic silicon release agent and 1-2 parts of polyamide polyurea.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a plant fiber foam packaging material. Background technique [0002] EPS foam products are one of the main sources of environmental pollution. According to the "Circular Economy Promotion Law of the People's Republic of China", this product is facing elimination. However, EPS foam plastics are light in weight and flexible, and as a cushioning packaging material, there is no ideal substitute so far. [0003] At present, the main substitute is pulp molding cushioning packaging material, which uses pulp as raw material, which is formed by pulping, vacuum adsorption molding, and drying. Products are used in small electronic instruments, household appliances and other industries. However, the product is too dense, the impact resistance is poor, and the cushioning property is lower than that of EPS foamed plastic. Pulp with lots of wood. The pulping process pollutes wat...
