[0001] The invention relates to the technical field of packaging, in particular to a production device for a perforated stretch film for packaging. Background Art

[0002] In today's logistics and packaging field, how to effectively maintain the freshness and vitality of vegetables, fruits, and flowers has become a topic that cannot be ignored. Traditional packaging materials often have problems such as poor air permeability and improper humidity management, which leads to the degradation of the quality of the packaged objects during transportation. In order to solve this problem, a new type of perforated breathable wrapping film production device came into being. It not only optimizes the performance of packaging materials, but also greatly improves packaging efficiency and environmental protection, injecting new vitality into the sustainable development of modern agriculture and flower industry.

[0003] With consumers' increasing demands for food freshness and the rapid development of e-commerce and cold chain logistics, the requirements for packaging materials are becoming more stringent. Although traditional plastic wrapping films have good fixing and protection effects, their sealing is too strong, which can easily lead to water vapor accumulation inside the packaging, accelerating the decay of fruits and vegetables and the withering of flowers and plants. Therefore, the development of a wrapping film that can maintain packaging stability and achieve ventilation has become an urgent need in the industry.

[0004] After the existing perforated stretch film production device completes the punching process of the stretch film each time, since the stretch film is relatively thin, the punched waste is easy to adhere to the punching block, which will affect the next punching operation and it is difficult to collect the punched waste in a centralized manner. In view of the above problems, the existing equipment needs to be improved. Summary of the invention

On the punching block, the perforated breathable wrapping film has a wide range of applications, especially for the packaging of fruits, vegetables, flowers and green plants for long-distance transportation. Its unique breathable design effectively prolongs the shelf life of the packaged goods, reduces losses and increases the value of the goods. At the same time, it is also of great significance to reduce packaging waste and promote the development of circular economy. The presence of air holes keeps the oxygen and carbon dioxide concentrations in the package in a dynamic balance, slows down the respiration of fruits and vegetables, and prolongs the storage period. For flowers and plants that are easily damaged, moderate air permeability effectively reduces the extrusion damage during transportation and keeps the plants fresh. The use of degradable materials reduces the generation of plastic waste, which is in line with the global pursuit of sustainable development. The perforated wrapping film production device for packaging can achieve the purpose of centralized collection and cleaning of waste materials through the coordinated use of the rotating plate, the annular water tank, the lifting rod and the filter cartridge. Water is stored in the annular water tank. After the waste materials are blown down, they will fall into the water and float on the water surface. The annular water tank can rotate slowly together with the rotating plate to facilitate the transportation of the waste materials to the filter cartridge for centralized collection and treatment. After the lifting rod and the filter cartridge are lifted, the waste materials in the filter cartridge can be centrally cleaned out. BRIEF DESCRIPTION OF THE DRAWINGS
