2022 Latest Design Aluminum For Caps - red and black color neck PVC heat shrink capsules for wine bottle – Wonderfly

The production principle of the material:

The stable state of the polymer chain tends to be a coiled state. When the polymer is heated and melted in a highly elastic state, the polymer chain is stretched and oriented under the action of external force, and after the rapid cooling reaches the glass transition temperature, the orientation state of the polymer chain is frozen. When the temperature rises again, the polymer chain tends to be in a stable state, coiling occurs, and macroscopically, it appears as shrinkage.
1. The surface of the PVC heat shrinkable film is smooth, uniform in thickness and thickness, no significant spots, no oil stains, impurities, or folding, which can improve the quality of product packaging.
2. After the packaging is shrunk, it is stored under the natural environment standard of 30 degrees, and there will be no color change such as fading and fading.
3. The PVC shrink film can be tightly packed, firm, waterproof, moisture-proof, dust-proof and beautiful.
PVC heat shrinkable film has the characteristics of good transparency, easy shrinkage, high strength, and the shrinkage rate can be adjusted at will according to customer needs. In addition, the application is very simple, only need to use hot air to stick the film to the product.
