Main characteristics of PVC heat shrink bottle caps
Main features
1. Excellent shrinkage: PVC material has a high shrinkage rate (up to 50% or more) after heating, and can tightly fit various shapes of bottle mouths, including irregular shapes.
2. Good sealing: After shrinking, it tightly adheres to the bottle body, effectively preventing dust and moisture from entering, and providing a certain degree of sealing protection for the contents, preventing moisture and leakage.
3. Powerful anti-counterfeiting function: This is one of its most core applications. Once the packaging is shrunk, in order to open the bottle cap, it must be destroyed (torn apart). The characteristic of one-time destruction makes it an effective anti-counterfeiting measure, and consumers can easily identify whether the product has been opened.
4. Decoration and identification: High quality color printing can be carried out to enhance the appearance grade of the product, while also carrying important information such as brand information, product name, production date, anti-counterfeiting query QR code, etc.
5. Strong adaptability: Suitable for bottle bodies made of various materials such as glass, plastic (PET, HDPE, etc.), ceramics, etc.
6. High cost-effectiveness: Compared to other complex anti-counterfeiting packaging technologies, PVC heat shrink bottle caps have lower production costs and higher cost-effectiveness.
