Description

Technical Field

[0001] This utility model relates to the field of medical sterilization bag technology, specifically a high-strength medical sterilization bag. Background Technology

[0002] Medical sterilization paper-plastic bags have a structure consisting of one side of paper and one side of plastic composite film. They are used for packaging medical devices to be sterilized and belong to the initial inner packaging of the product. They are also known as sterilization packaging bags, disinfection packaging bags, and medical packaging bags.

[0003] The existing announcement number CN211711486U discloses a medical sterilization paper-plastic bag, including a bag body. A second sealing strip is provided at the top inner side of the front surface of the bag body, and a first sealing strip is provided at the top inner side of the rear surface of the bag body. The first sealing strip is located on one side of the second sealing strip. An adhesive layer is provided at both ends of the first sealing strip. One side of the adhesive layer is located on one side of the connecting strip, and a stretch layer is provided on the other side of the adhesive layer. Connecting strips are provided on both sides of the top of the bag body. By adding an adhesive layer and a stretch layer at both ends of the connection between the first and second sealing strips, respectively, and the stretch layer is made of high molecular weight polyethylene material, which has good tensile strength, the bag body at both ends of the connection between the first and second sealing strips is effectively prevented from tearing when the staff opens the paper-plastic bag with a little force. This makes it easier for staff to open the medical sterilization paper-plastic bag and reduces the loss of the medical sterilization paper-plastic bag.

[0004] While existing technologies have enhanced the strength of sterilization bags to some extent, their antibacterial effect is limited, and the tear points are prone to tearing the bag. Therefore, we propose a high-strength medical sterilization bag. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength medical sterilization bag to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength medical sterilization bag, comprising a bag body, wherein an opening sealing strip is provided at the open end of the bag body, an end sealing layer is provided on one side of the opening sealing strip, a tear strip is provided at the end sealing layer of the bag body, and tear openings are provided at both ends of the tear strip of the bag body; the bag body is composed of an outer membrane, a puncture-resistant layer, an inner membrane, and an antibacterial coating, wherein a puncture-resistant layer is provided on the inner side of the outer membrane, an inner membrane is provided on the inner side of the puncture-resistant layer, and an antibacterial coating is sprayed on the inner side of the inner membrane.

[0007] Preferably, an inner reinforcing film is attached to the bottom sealing layer of the bag body.

[0008] Preferably, the inner reinforcing membrane is also composed of an outer membrane, a puncture-resistant layer, an inner membrane, and an antibacterial coating.

[0009] Preferably, both the outer and inner membranes are made of polyethylene film.

[0010] Preferably, the puncture-resistant layer is made of PA film.

[0011] Preferably, the antibacterial coating is a nano-silver coating.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The bag body has tear openings at both ends of the tear strip. The tear strip is composed of multiple dot-shaped through holes. Triangular notches are opened at both ends of the dot-shaped through holes along the direction of the tear strip, which makes it easy to tear the bag body from the opening and tear along the tear line, thus avoiding tearing the bag body.

[0014] 2. An inner reinforcing membrane is affixed to the bottom sealing layer of the bag body. The inner reinforcing membrane increases the strength of the bottom of the bag body and prevents instruments from puncturing the bottom of the bag body. The outer membrane, puncture-resistant layer and inner membrane improve the strength and puncture resistance of the bag body. Attached Figure Description
