Description

Technical Field

[0001] The utility model relates to the technical field of paper-plastic bag processing, in particular to a paper-plastic bag easy-tear edge processing device. Background Art

[0002] Medical paper-plastic bags are a kind of packaging material commonly used in the medical field. It combines the characteristics of paper and plastic and plays an important role. Its main features include: Paper part: It uses medical dialysis paper with good air permeability, which allows the sterilizer to penetrate smoothly and achieve effective sterilization. The paper surface is flat and the printing is clear, which is convenient for marking and recording relevant medical product information. Plastic part: It is usually a transparent plastic film, which provides good visibility and is convenient for viewing the internal items. It has excellent barrier properties and can effectively prevent the invasion of moisture, microorganisms, etc.;

[0003] When processing paper-plastic bags, an easy-tear notch is opened. This is designed to make it easier for consumers or users to tear open the bag when opening the package. The design of the easy-tear notch not only facilitates the use of users, but also takes into account the safety and aesthetics of the packaging;

[0004] The existing easy-tear processing device generally processes the paper-plastic bag by punching, but such a cutting and pressing method will cause the paper-plastic belt to pause during the feeding period, and the pause will provide an operation gap, resulting in insufficient continuity of the device during operation; at the same time, after the easy-tear processing, a small amount of waste will be generated, which will adhere to the punching tool or the cutting surface, and continuous operation will cause the cutting effect of the tool to decrease, and the waste generated by the easy-tear is relatively light, which makes it inconvenient for personnel to clean it;

[0005] Therefore, the present application proposes a paper-plastic bag easy-tear edge processing device. Utility Model Content
