Composite material for medical device packaging box, and easy‑peel sealing process for cover material

Abstract

A composite material for a medical device packaging box, and an easy‑peel sealing process for a cover material. The composite material for a medical device packaging box comprises a packaging box plastic sheet material (1); the top of the packaging box plastic sheet material (1) is provided with an easy-peel film (3); a cover material (4) is mounted at the top of the packaging box plastic sheet material (1); the easy-peel film (3) is attached to the surface of the inner wall of the cover material (4). The packaging box plastic sheet material (1) can be made of PVC, APET, PETG, PP, PS, PP, and PC, and the cover material (4) is made of a non-adhesive-coated HDPE cover material, thereby preventing adhesive leakage and adhesive shedding; in addition, due to compositing with an HDPE easy-peel film, the thickness of the sheet material is relatively uniform, so that the packaging box plastic sheet material (1) and the HDPE cover material can be perfectly adaptively bonded, thereby improving the easy-peel effect between the packaging box plastic sheet material (1) and the cover material.

Description

Medical instrument packaging box composite material and cover material sealing easy-to-uncover process TECHNICAL FIELD

[0001] The present application relates to the technical field of medical instrument packaging box composite materials, in particular to a medical instrument packaging box composite material and cover material sealing easy-to-uncover process. BACKGROUND

[0002] A medical instrument packaging material known to the inventor uses American DuPont Tyvek material. The DuPont Tyvek material is coated by a coating device to have a layer of hot-sensitive adhesive. The Tyvek material with the adhesive layer is heat-sealed with various sheet materials to achieve an easy-to-uncover effect for the medical instrument, which is convenient for doctors to uncover and ensures that the medical instrument is not contaminated.

[0003] However, the Tyvek material coating technology also has problems. Specifically, the Tyvek material itself has uneven thickness, and the coating layer may have the risk of missing glue or too much glue. The missing glue risk refers to the contamination of the Tyvek material and the packaging box medical instrument, which has the risk of not being heat-sealed firmly and being easy to open the glue. The too much glue problem refers to the fact that the coating layer is very thick in thin places. Ethylene oxide gas enters the sterilization through the surface of the Tyvek material, and the entering speed is very slow. The medical instrument needs more than 20 days in the analysis process, and the medical instrument has ethylene oxide residue. The medical instrument residue exceeds the standard, which poses a great risk to the patient. Moreover, the Tyvek material coating layer is in surface contact with the medical instrument, which is easy to fall off the glue. The medical instrument absorbs the particles of the fallen glue of the Tyvek material, which is contaminated and can also cause medical instrument accidents. SUMMARY

[0004] The purpose of the present application is to provide a medical instrument packaging box composite material and cover material sealing easy-to-uncover process to solve the problems raised in the background.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions.

[0018] 1. By setting the material of the plastic sheet of the packaging box as an easy-to-peel sheet, and setting the material of the first adhesive layer water-based adhesive as water-based adhesive, the glue leakage and glue dropping can be prevented, the plastic sheet of the packaging box and the cover can be perfectly matched and bonded, and the first adhesive layer water-based adhesive and the plastic sheet of the packaging box are relatively uniform, thereby facilitating the peeling of the medical instrument packaging box, reducing the product failure rate, and thus reducing the production cost.

[0019] 2. By using various composite easy-to-peel sheets, HDPE easy-to-peel films, water-based adhesives, and formed sheets as raw materials, and by extruding the raw materials through glue rollers and heating rollers, and adding glue during extrusion through the glue rollers, an HDPE easy-to-peel composite sheet is formed, thereby improving the easy-to-peel property of the cover and the easy-to-peel effect between the plastic sheet of the packaging box and the cover.
