Abstract

The invention discloses a packaging bag with a rough surface. The packaging bag is prepared from the following raw materials in parts by weight: 80-100 parts of plastic and 50-70 parts of composite coating, wherein the plastic forms the packaging bag main body, the composite coating is coated on the outer layer of the packaging bag, the composite coating is of a multi-layer structure, the composite coating comprises a bonding layer, a scratch-resistant layer, a waterproof layer and an attapulgite pasty waterproof putty composite layer from inside to outside, the attapulgite pasty waterproof putty composite layer is a composite layer composed of matt varnish, a coagulator and frosted particles, the attapulgite pasty waterproof putty composite layer comprises modified nano titanium dioxide accounting for more than 30% of the total content of the layer and oyster shell powder accounting for 10% of the total content of the layer, the modified nano titanium dioxide can be surface-modified nano titanium dioxide, silver ions accounting for 1.5%-4.5% of the total weight of the surface-modified nano titanium dioxide are added when the surface-modified nano titanium dioxide is prepared, anda silane coupling agent or a titanate coupling agent is adopted. The packaging bag has good material performance and antibacterial effect.

Description

technical field [0001] The invention relates to the technical field of packaging bags, in particular to a packaging bag with a rough surface, especially a packaging bag with a rough surface and a preparation method thereof. Background technique [0002] Plastic bags are bags made of plastic (commonly used plastics include polyethylene, polypropylene, polyester, nylon, etc.) as the main raw material. They are indispensable items in people's daily life and are often used to hold other items. thing. It is widely used because of its cheap, extremely light weight, large capacity, and easy storage. China's annual output of plastics is 30 million tons, and its consumption is more than 6 million tons. Packaging bags are used to pack various supplies, and generally belong to a kind of plastic bags, which make the goods convenient to transport and store during the production and circulation process, and are widely used in daily life and industrial production. Classified by raw mate...
