Problems solved by technology

However, the above method of making bags has some disadvantages. 1. The air permeability effect of the gummed paper needs to be improved. 2. The cost of the gummed paper is relatively high. 3. The heat seal strength between the gummed paper and the coated paper is not high. 4. No antibacterial 5. The processing process of the coated paper itself is to apply molten LDPE on the surface of the base paper. The melting temperature of LDPE is 315-340 degrees Celsius, which is close to the decomposition temperature of LDPE. A large amount of smoke is generated during the processing process, causing environmental pollution. Film paper will have an odor

Abstract

The invention provides an antibacterial self-adhesive coated paper. The antibacterial self-adhesive coated paper comprises a base paper layer and a heat seal layer, a bonding layer is arranged betweenthe base paper layer and the heat seal layer, and the heat seal layer comprises, by weight, 1-2 parts of antibacterial master batches, 40-60 parts of MLLDPE, 30-50 parts of EAA and 1-20 parts of DuPont special resin. The coated paper can be directly heat-sealed with the base paper, and has good antibacterial property.

Description

technical field [0001] The invention relates to the field of medical device packaging, in particular to an antibacterial self-adhesive coated paper. Background technique [0002] During the production process of medical packaging bags, the edges of the two layers of raw materials are usually pressed together by heat sealing to form a bag. Coated paper has the characteristics of waterproof, oil-proof and heat-sealing, and is a commonly used raw material for medical packaging bags. For medical packaging bags that need to be sterilized, especially by ethylene oxide, the packaging bag needs to have a certain degree of air permeability to allow ethylene oxide to enter the packaging bag, and the contents of the packaging bag should be sterilized. Sterilization operation. [0003] Coated paper itself has no air permeability or poor air permeability. Therefore, the use of coated paper as a raw material for medical packaging bags needs to be combined with other air-permeable materi...
