Description

Technical Field

[0001] The utility model relates to the technical field of packaging film processing, in particular to a packaging film punching device. Background Technique

[0002] When using a heat shrink packaging machine for full packaging, the packaging film needs to be punched with some small holes. This is because during the heat shrink packaging process, the gas inside the film needs to be discharged through these small holes to prevent the film from bulging due to the expansion of the internal gas, which affects the aesthetics and tightness of the packaging. Especially when the product needs to be fully packaged and has high requirements for the packaging appearance, punching is particularly important. For some packaging products that require breathability, such as fresh vegetables and fruits, the small holes on the packaging film help to maintain the freshness of the products. Through the small holes, the gas inside the packaging can exchange with the outside to a certain extent, adjusting the oxygen and carbon dioxide concentrations inside the packaging, thereby extending the shelf life of the products.

[0003] The existing punching device uses a punching roller to punch the packaging film. The spacing between the punches is relatively single and not suitable for the punching positions of packaging films of different sizes. Moreover, when the punching roller rotates, it is easy to deform the packaging film, affecting the production quality and production efficiency. In view of the above problems, a packaging film punching device is proposed. Content of the Utility Model
