The characteristic of the heat shrinkable film is the phenomenon of shrinkage recovery.
With the continuous improvement of China's economic level, people's lifestyles have become more complex and diverse, and the use of plastic packaging has become more diversified. In particular, people are increasingly demanding food packaging. The packaging bag market is also expanding with the demand. The big advantage of the packaging bag is that the market space is broad, because our life is inseparable from it, especially the food packaging industry, which not only can extend the shelf life of food, but also solve the food hygiene problem. It has become a dependent product in the food industry. In addition to food, it can be used in a wide range of industries such as medicine and food. Therefore, plastic packaging has a wide application space and the market prospect is very good.
Heat shrink film is also the protector of construction and transportation materials. It is suitable for packaging of multiple products and packaging with trays. It is convenient for transportation and easy to sell. It is easy to mechanize, save labor and material resources, and can partially replace carton and wooden box packaging. The heat shrinkable film is used to replace the tying rope package with bottled beer to prevent bottled beer from blasting and injuring people. It has been widely used in fast food, ceramic products, tea sets, machinery parts and other fields. It is used for various PET bottled beer and beverage labels, which can reduce the process of removing labels and is easy to recycle. In military machinery, hardware tools, the combination of heat shrink film and gas phase anti-rust technology to replace the anti-rust oil method, enhance the anti-rust ability, significant.
In addition, the heat shrinkable film protrudes from the phenomenon of shrinkage recovery. That is, when the heat shrinkable film is created, the heating well is stretched in the corresponding direction in advance, and then quenched to arrange the chain molecules in the stretching direction. When the film is reheated to the scent of stretching, the chain molecules recover to the original disordered state, and the thinness is also restored to the size before stretching, that is, the phenomenon of shrinking X original. The heat shrinkable sleeve label mainly adopts the gravure printing method, and the printed graphic has bright color and good saturation. Because it can decorate the packaging container, it can highlight the appearance of the product and improve the appearance and decoration of the product, which can produce a good shelf effect. In the sleeve labeling process, the label and the container can be integrated into one without using an adhesive, and the large-scale connection operation of the commodity can be realized, and the production cost is greatly reduced.
The heat shrinkable film is widely used in the whole assembly packaging of aluminum profile packaging, doors and windows, wine, cans, mineral water, various beverages, cloth and other products. PVC shrink film, with added ingredients to enhance its heat resistance, toughness, ductility and so on. The upper layer of the surface film is lacquer, the main component in the middle is polyvinyl chloride, and the lower layer is a back-coated adhesive. It is a well-loved, popular and widely used synthetic material in the world today. Among the materials that can produce three-dimensional surface films, PVC is a more suitable material. It is widely used in the building materials industry and packaging industry due to its special properties (rain, fire, static, easy to form) and PVC low input and high output.
The heat shrinkable film machine can assemble the parts into a whole and is suitable for single-piece packaging. Secondly, the PVC heat shrinkable film is close to the surface of the package, so that people have the feeling of sticking the adhesive, making the product more beautiful, crisp and shiny, which is a wise choice for improving the competitiveness of the product. The important point is that PVC has low input and high output, which is why many merchants choose it. The high-coverage product provides a surface shield that forms a very light, sheltered surface around the product to achieve dust, oil, moisture, water, and theft. It is especially important that the compressed film package allows the packaged articles to be subjected to an average force to prevent damage caused by uneven force, which is not possible with traditional packaging methods (bundling, packaging, tape, etc.).
