What are the roles of PVC heat shrinkable films in daily applications? PVC heat shrinkable film is used in industries such as food, beverage, daily necessities, toys, and other industries. The appearance of packaging varies. PVC heat shrinkable film improves the quality of product packaging, and also has a certain protective and dustproof effect. It is a type of heat shrinkable film that many enterprises are relatively satisfied with. Let's take a look at the role of PVC heat shrinkable film in daily applications with Bondle!
PVC heat shrinkable films can be divided into soft PVC heat shrinkable films and hard PVC heat shrinkable films. Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for floors, ceilings, and the surface layer of leather. However, due to the presence of softeners in soft PVC (which is also the difference between soft PVC and hard PVC), it is easy to become brittle and difficult to store, so its scope of use is limited. Rigid PVC does not contain softeners, so it has good flexibility, is easy to form, is not fragile, and has a long storage time, so it has great development and application value. Hereinafter referred to as PVC. The essence of PVC is a vacuum plastic absorbing film, which is used for the surface packaging of various types of panels, so it is also known as decorative film, adhesive film, and is used in many industries such as building materials, packaging, medicine, and so on. The building materials industry accounts for a large proportion of 60%, followed by the packaging industry, as well as several other industries with small-scale applications.
Printing grade PVC shrink film, as the name implies, is used for printing and can be processed into printed labels. Most beverages on the market use PVC labels, such as those used outside black tea, green tea, and mineral water bottles.
PVC heat shrinkable film is widely used in our lives. PVC heat shrinkable film is made by mixing vinyl PVC resin with more than ten kinds of auxiliary materials and then expanding it twice. Its use method is to calculate the circumference based on the size of the coating, convert it to the folded diameter (folded diameter=1/2 of the circumference), and then appropriately enlarge the folded diameter. PVC heat shrinkable film shall be selected according to the product specifications of our factory, and suitable PVC heat shrinkable sleeve film shall be selected. Install the casing film on the packaging, and at a temperature of 100 ℃ - 160 ℃, it can take 6-10 seconds (the actual temperature of the casing film is 86 ℃, and the temperature of the left glaze winter packaging is less than 10 ℃).
1. The shrink film has good wear resistance and high strength, ensuring acceptance of the weight of the content.
2. The heat shrinkable film has a high transparency, so the label has a bright color and good luster.
3. Heat shrinkable packaging can package special-shaped products that are difficult to package by ordinary methods.
4. After shrinkage, the heat shrinkable film tightly adheres to the product, making the packaging compact and revealing the appearance of the product. The packaged product is beautiful.
5. Heat shrinkable packaging has good sealing, moisture-proof, antifouling, and rust preventive effects, which can extend the storage period of food, facilitate storage, and facilitate outdoor stacking.
6. Heat shrinkable film can provide 360 degree decoration for packaging containers, and can print product information such as product descriptions on labels, enabling consumers to understand the performance of products without opening the packaging.
It should be noted that the selection of the sleeve film should not be too large to avoid causing improper crimping or shrinkage. The shrinkage temperature should not be too high or too low to avoid cracking or poor shrinkage. Storage and transportation should be protected from heavy pressure, impact, rain, and sunlight. The main products should be stored in a dry warehouse with an ambient temperature not exceeding 30 ℃. It is strictly prohibited to place them around heat sources to avoid cracking or shrinkage deformation damage. The storage period is 15 months.
To sum up, the editor explained to you the role of PVC heat shrinkable film in daily applications, the use of 2022 PVC heat shrinkable film, and the proportion of heat shrinkable film in the packaging industry is very large. Enterprises can choose a suitable heat shrinkable film and contact the packaging manufacturer for customization.
