Heat shrinkable film can be used for personal decoration of packaging containers

The heat-shrinkable sleeve label mainly adopts the gravure printing method. The printed graphics have bright colors and good saturation. Because it can decorate the packaging container, highlight the appearance of the product, improve the appearance of the product, and produce a good shelf effect. 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 goods and greatly reduce the production cost. It adopts the printing method to protect the graphics and text, and enhance 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, corrosion-resistant, impact-resistant, tear-resistant, odorless and non-toxic, and can play an anti-counterfeiting role. Heat-shrinkable sleeves can also protect consumers from accidental injuries caused by damaged or ruptured containers. It is stable at normal temperature, shrinks when heated (above the glass transition temperature), and heat shrinks more than 70% in one direction. The advantages of heat shrinkable polyester film packaging are: ①The skin is transparent and reflects the image of the product. ②Tightly tighten the packaging, good anti-scattering. ③Prevent rain, moisture, and mildew. ④ No recovery, with a certain anti-counterfeiting function. Heat-shrinkable polyester film is often used in the convenience food, beverage market, electronic appliances, and metal products. In particular, shrink labels are the most important application areas. Because with the rapid development of PET beverage bottles, beverage bottles such as cola, sprite, and various juices require PET heat shrinkable film to be matched with heat seal labels. They belong to the polyester category and are environmentally friendly materials that are easy to recycle. use. PVC heat shrinkable film has the characteristic of being heat-shrinkable, and the pvc heat shrinkable film will shrink when heated, so as to tightly cover the surface of the packaged article. At the same time, it also has the characteristics of high strength, good transparency, waterproof, moisture-proof, anti-pollution ability, and excellent electrical insulation performance. PVC heat shrinkable film can be used for insulation packaging of electrical appliances and electronic components (such as the outer packaging of dry batteries); packaging of general items and packaging in contact with food. Using it as a packaging material can not only simplify the packaging process and reduce the packaging volume, but also because the shrinking transparent film tightly wraps the packaged item, it can clearly show the color and shape of the item, so pvc heat shrinkable film is widely used in commodity packaging on. With the development of science and technology and the progress of human society, we are more and more advocating energy saving and environmental protection. PVC heat shrinkable film is mainly made of plastic and paper. This undoubtedly pushes the development of the paper industry to a peak and makes the packaging market costly. Expansion, the price increased significantly, thus promoting the industrial development of PVC heat shrinkable film. This has provided convenience for human life and promoted the harmonious development of society. At the same time, food packaging is the most widely used field of film, which improves commercial value and achieves a win-win situation of mutual encouragement and mutual encouragement. Following the pace of the times, the continuous development of PVC heat shrinkable film technology and the adjustment of the industrial model will play a more important role in promoting the plastic and packaging industry to the high-end.
