Abstract

The invention discloses a glue-coated medical device packaging material that can be peeled off stably and cleanly. The main resin of the resin layer and the glue layer is a water-based adhesive. The invention also discloses its preparation method; the invention is suitable for pressure steam and ethylene oxide sterilization methods, and the sterilized items have a long shelf life, which ensures product quality and safety for clinical application; excellent barrier performance, reduces metal The incidence of rust and other losses of similar items can be reduced, and the service life of the items can be extended; the stable and easy-peel sealing effect after sterilization reduces the labor intensity of the nursing staff.

Description

technical field [0001] The invention relates to a glue-coated medical device packaging material and a preparation method that can be stably and cleanly peeled off, and is suitable for light-weight medical device packaging, such as gloves, syringes, catheters, gauze and the like. Background technique [0002] The quality of medical device sterilization is directly related to the quality of medical care and the recovery of patients. In the past, medical devices were sterilized by double-layer plain cotton cloth, unsealed hard containers or film packaging. This kind of packaging has a short shelf life and high cost of sterilized items. Insufficient, and its sealing strength is high, and it is not easy to peel off; the patent with the authorized announcement number of CN104260990B: a medical device packaging film and its manufacturing method, after the yam is crushed, the clarified liquid is removed, and the paste left is dried After pulverization, yam powder is obtained, yam po...
