Product Advantages & Customer Benefits
- Tamper-Evident Security: Once shrunk, the ring forms a tight seal that breaks upon opening, providing clear visual evidence of tampering. This enhances consumer trust and product integrity.
- High Heat Resistance: Withstands temperatures up to 120°C, ensuring the ring remains stable during hot filling processes, pasteurization, or when exposed to warm environments.
- Perfect Fit for Standard Bottles: The 28mm ID and 40mm length are designed to fit standard wine bottle necks snugly, reducing the risk of slipping or misalignment.
- Easy Application: Simply slide the ring over the bottle neck and apply heat (hot air gun, shrink tunnel, or steam). The ring shrinks uniformly, covering the cap and neck area.
- Customizable Appearance: Available in transparent or various colors. You can also print logos, barcodes, or product information on the ring for branding purposes.
- Cost-Effective Packaging: Lightweight and low material usage compared to other sealing methods, reducing shipping costs and environmental footprint.
- Consistent Quality: Manufactured under strict quality control by a factory with over 25 years of experience. Each batch is checked for dimensional accuracy and shrinkage performance.
Technical Highlights
Our PVC shrink rings are made from high-grade PVC resin, free from harmful plasticizers where possible. The material exhibits excellent flexibility, allowing it to conform to the bottle neck shape without cracking. The shrinkage process is reversible only by heating, ensuring the seal remains intact under normal conditions. The 120°C heat resistance means the ring can withstand typical hot-fill temperatures (up to 85°C) and additional thermal processes without deforming or losing its seal.
Applications
- Wine bottles (still and sparkling)
- Champagne and sparkling wine bottles
- Olive oil and vinegar bottles
- Spirits and liquor bottles
- Juice and beverage bottles
- Cosmetic and pharmaceutical containers (where tamper evidence is required)
