Abstract

The invention discloses medical paper bag gum and a production method thereof. According to parts by weight, 25 parts of B04 medical sealant particles are put in a stirring kettle; then 37.5 parts of 120# solvent oil and 37.5 parts of methylbenzene are put in the stirring kettle after being mixed; and finally, 0.2 part of CB-901 tackifier is put in the stirring kettle and is stirred for 6-12 hours at the temperature of 25-35 DEG C to obtain the medical paper bag gum. The invention product takes fluidic glue water and is directly coated by a coating roller, so that convenient use is achieved; and the gum has the characteristics of easy sizing, even coating and high stripping strength, can guarantee the safety of medical products in packaging bags, has good sealing and damping performance, and is suitable for any normal leakage tests.

Description

technical field [0001] The invention relates to an adhesive and a production method thereof, in particular to a medical paper bag glue and a production method thereof. Background technique [0002] Medical paper bag is a product that meets the requirements of modern medical packaging. It is generally made of paper, coated paper or lacquered paper. It has the characteristics of reliable sealing, heat sealing and easy tearing. This product can be used for the packaging of medical gloves, gauze, masks, disinfection towels and small medical instruments. Generally, the adhesive layer of the raw material is bonded to the coating layer through the high temperature and high pressure of the bag making machine, so that it can achieve a good airtightness, and the interface required to be peeled off for the medical packaging paper bag is absolutely clean during use. In view of these characteristics of medical paper bags, it is necessary to select a special hot-melt sealing adhesive...
