Abstract

The invention discloses a stably and cleanly stripped glued medical instrument packaging material comprising a gloss paint protective layer, an ink-printed paper sheet layer, a barrier layer and a glue layer arranged from top to bottom; a resin layer is extruded and compounded from each of two sides of the barrier layer; and main resin of the glue layer is a water-based adhesive. The invention further discloses a preparation method of the stably and cleanly stripped glued medical instrument packaging material; the stably and cleanly stripped glued medical instrument packaging material is suitable for a pressure steam and ethylene oxide sterilization way, the storage period of a sterilized product is long, and the product quality and clinic application safety are guaranteed; the stably andcleanly stripped glued medical instrument packaging material is excellent in barrier property and capable of reducing the occurrence rate of loss such as rustiness of metal goods and prolonging the service life of the goods; and the stably and cleanly stripped glued medical instrument packaging material has stable and easy stripping and sealing effects after being sterilized, so that the labor intensity of nursing staffs is relieved.

Description

Technical field [0001] The invention relates to a packaging material for glue-coated medical devices that can be stably and cleanly peeled off and a preparation method, which are suitable for packaging of light-weight medical devices, such as gloves, syringes, catheters, gauze, and the like. Background technique [0002] The quality of sterilization of medical devices is directly related to the quality of medical treatment and the rehabilitation of patients. In the past, medical devices were sterilized by double-layer plain cotton cloth, unsealed rigid containers or film packaging. This kind of packaging has short shelf life and high cost of sterilized items. Its sealing strength is relatively high, and it is not easy to peel off; the patent authorized announcement number is CN104260990B: a medical device packaging film and its manufacturing method, by crushing the yam to clear liquid, and leaving the paste to dry After crushing, the yam powder is obtained. The yam powder, carbox...
