pvc (Polyvinyl chloride) It has non-flammability, high strength, weather resistance and excellent geometric stability, and has strong resistance to oxidant, reductant and strong acid. In addition, due to its good flexibility, shrinkage, good processing and labeling performance, strong chemical corrosion resistance, firmness and durability, it is suitable for long-term outdoor use. PVC has excellent inking performance and can be made into various colors (PVC-4 light blue, PVC-5 White), A wide range of applications. It is suitable for labels with high performance requirements such as water resistance, oil and chemicals. The top is mainly printed with 50u PVC as the bottle label, while the Wahaha bottle label generally uses 40u PVC.

packaging films are mostly made of polyvinyl chloride resin, which is processed and plasticized by adding various additives such as plasticizer and stabilizer. Due to its material characteristics, the safety problem of PVC packaging film in contact with food during use is determined. Besides, PVC packaging film waste will also have serious adverse effects on the ecological environment. Based on this, environmental protection departments in many countries in the world have promulgated relevant laws and regulations to prohibit or restrict the extensive use of PVC. In addition, the degradation of PVC label materials is poor, which has a negative impact on environmental protection.

PVC Heat Shrinkable film is suitable for outer packaging and combination packaging of various products. This product is characterized by good transparency, strong shrinkage and easy operation. The packaged product can be sealed, moisture-proof, insulated, bright, firm and beautiful.

1. Shrink freely-- The shrinkage rate can reach up to 50%, which can be used as a bottle label material to cling to the bottle during processing and molding.

2. Crystal luster-- High transparency can clearly display the appearance of the product and increase the sense of perception.

3. Tight sealing-- Good sealing performance, not easy to open, especially suitable for high-speed automatic packaging.

4. Tough and tear-resistant-- Good toughness, not easy to embrittlement, durable tear strength.

5. Collective packaging--Increase the number of sales and increase customers' desire to buy.

Application: PVC bottle label
