Problems solved by technology

The existing plastic packaging materials have a short service life. On the one hand, due to their poor strength and easy damage, on the other hand, after a long service life, bacteria often grow on the surface, and the barrier property is poor, so that the bacteria on the surface can penetrate into the packaged items inside, resulting in mildew and deterioration of the packaged items

Abstract

The invention provides a mold-proof plastic packaging bag and a preparation method thereof. The mold-proof plastic packaging bag is prepared from the following raw materials in parts by weight: 30-65 parts of polyethylene resin, 10-25 parts of nano-silver grains, 10-25 parts of nano-titania grains, 5-15 parts of coupling agent, 3-8 parts of plasticizer, 5-8 parts of antistatic agent, 2-8 parts of stabilizer and 8-20 parts of filler. The nanometer anti-microbial grains are added, the blending ratio of polyethylene resin, nanometer anti-microbial grains and processing additives is optimized and the components and rate of the processing additives are optimized, so that the acquired mold-proof plastic packaging material has excellent anti-microbial mold-proof effect, high strength and long service life.

Description

technical field [0001] The invention belongs to the technical field of plastic products, and in particular relates to a mildew-resistant plastic packaging bag and a preparation method thereof. Background technique [0002] Plastic is widely used in daily life, various industries and high-tech fields because of its light weight, easy processing, beautiful and practical, and low price. The existing plastic packaging materials have a short service life. On the one hand, due to their poor strength and easy damage, on the other hand, after a long service life, bacteria often grow on the surface, and the barrier property is poor, so that the surface bacteria can penetrate into the packaged items inside, resulting in mildew and deterioration of the packaged items. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a mildew-resistant plastic packaging bag and a preparation method thereof, and the specific tec...
