Abstract

The invention discloses a low-temperature-resistant outer cover bag multi-layer co-extrusion film comprising an upper film body and a lower film body, the upper film body and the lower film body are each of a two-layer structure, the outer layer of the upper film body is obtained by blending and granulating homo-polypropylene and an ethylene-octene elastomer, and the inner layer of the upper filmbody is formed by blending a PP-modified easy-to-tear material and a slipping agent; the inner layer of the lower film is formed by blending a polypropylene random copolymer layer and a slipping agent, and the outer layer of the lower film is formed by blending homo-polypropylene and an ethylene-octene elastomer for granulation. The outer cover bag multi-layer co-extrusion film meets the sterile requirements of soft bag infusion drugs for operating rooms, ICUs and hospital configuration centers; a bag can be opened to be easy to uncover and tear, and the easy-to-tear effect is that the bag istorn linearly; process is smooth, and operation is convenient.

Description

technical field [0001] The invention belongs to the field of overcoat protective film for infusion products, in particular to a multilayer co-extrusion film for a low-temperature resistant overcoat bag for cooking and sterilization and a preparation method thereof. Background technique [0002] Soft bag infusion medicines used in operating room, ICU and hospital configuration center are required to be aseptic to ensure the safety of medication. Generally, the outer bag protective film of infusion products is only packaged after the infusion bag products are sterilized, which cannot be aseptic. According to the requirements of the invention, the package and the infusion product are steam-water-bath sterilized before steam sterilization after filling, and the product after bagging and sterilization needs to be refrigerated after entering the hospital, so the outer bag must also withstand low temperature and not be brittle split requirements. Specific requirements are as follo...
