Heat shrinkable film can also be customized

The heat shrinkable film can also be customized! The production process of heat shrink sleeve label is not complicated. First of all, the film material is printed in a back printing method, and a layer of white ink is printed thereafter to improve scratch resistance and safe shrinkage performance, and protect the container from fading caused by UV light. Then, the printed web material is processed into a tube, and is automatically or manually placed on the container to be labeled. Finally, let the container with the label set through the hot air or infrared channel, and use the heat to shrink the sleeve label and stick to the surface of the container. From the above production process, the heat shrinkable sleeve label has many advantages. First, the heat-shrinkable sleeve label mainly adopts the gravure printing method, and the printed graphics are bright in color and good saturation. Because it can decorate the packaging container personally, highlight the appearance of the product, improve the appearance of the product, and produce a good shelf. Effect; the second is that in the labeling process, the label and the container can be integrated without the use of adhesives, which can realize the large-scale connection operation of the product and greatly reduce the production cost; the third is that it uses the back printing method, which can be used In order to protect the image and text, it enhances the wear resistance of the heat shrinkable sleeve label in the transportation and sales links. From the perspective of functional requirements, heat shrinkable sleeve labels have the characteristics of moisture-proof, anti-corrosion, impact-resistant, tear-resistant, odorless and non-toxic; they can play an anti-counterfeiting role; protect consumers from damage or rupture of containers accidental damage. The most important thing is that this label can be recycled, which has significant advantages in saving costs and protecting the environment. However, there are also many difficulties in the design of heat shrinkable sleeve labels. When producing heat shrinkable sleeve labels, the most widely used film material on the market is PVC heat shrinkable film. This kind of film has many advantages such as water resistance, fire resistance, high transparency, high gloss, high shrinkage rate, etc., but the material easily generates toxic gas when burned, which is not conducive to environmental protection. As a new material, OPS heat shrinkable film is a kind of skin packaging material that meets environmental protection requirements. It has many advantages such as high strength, high rigidity, good gloss, high shrinkage, and compliance with food hygiene standards. However, due to the current market There are not many companies that produce this film in Shanghai, and they cannot fully meet the market demand for this film. As for the ink, the quality of the ink directly affects the printing effect of the heat shrinkable sleeve label. Practice has proved that UV flexo printing ink is a very good choice, and its biggest advantage is that it can achieve higher color strength through curing and drying, which also brings great challenges to traditional gravure inks. The heat shrinkable film packaging machine is also called the heat shrinkable packaging machine. Its main function is to wrap the product with a heat shrinkable film and then heat it so that the film shrinks and wraps the product tightly. The shrink film is used to wrap the product or package outside, and after heating, the shrink film shrinks and wraps the product or package, fully showing the appearance of the item, improving the product's displayability, and increasing the beauty and sense of value. The items packaged by the heat shrinking machine can be sealed, moisture-proof and pollution-proof, and protect the product from external impact. It has a certain cushioning property, especially when packaging fragile products, it can prevent the utensils from scattering when broken. Heat shrinking machine is widely used in food, beverage, medicine, daily chemical, hardware, wood products, stationery and other industries.
