30x44 mm Roll on Pilfer Proof Aluminum Plastic Cap Design & Function
- Tamper-Evident Mechanism: During the capping process, the cap is initially sealed through a crimping action, forming a breakable bridge (or perforation). When the bottle cap is opened for the first time, the bridge breaks, providing clear, irreversible tamper evidence.
- Resealability: After the first opening, a secondary thread is formed. This allows consumers to reseal the bottle, combining the security of a tamper-evident seal with the convenience of a screw cap.
ROPP Mechanism:
- Applied using a capping machine, which rolls the aluminum skirt onto the bottle threads to form a seal.
- Tamper-Evident Feature: The breakable aluminum band separates upon the first opening, leaving a visible "tamper-proof" ring on the bottle neck.
30x44 mm ROPP Aluminum Plastic Cap Features
| Features | Description |
| Security | The 30x44 mm ROPP Aluminum Plastic Cap is equipped with a tamper-evident band, ensuring that the cap leaves a visible mark after the first opening, preventing unauthorized refilling or tampering. This design is crucial for protecting product integrity. For high-end spirits brands, it provides an added layer of security, helping consumers identify whether the product has been tampered with, thus enhancing brand trust. |
| Seal Integrity | The 30x44 mm ROPP Aluminum Plastic Cap is typically fitted with a PE or EPE liner to create a strong sealing structure. This seal effectively prevents alcohol evaporation, ensuring the liquid inside retains its original flavor and quality. Additionally, the sealing performance prevents external air from entering the bottle, reducing oxidation and extending the product’s shelf life. Maintaining the original flavor is critical for premium spirits. |
| Durability | The 30x44 mm ROPP Aluminum Plastic Cap is made of corrosion-resistant 8011 aluminum, providing excellent resistance to alcohol corrosion. It can withstand prolonged exposure to high alcohol concentrations without degradation. Additionally, the plastic components enhance the cap's toughness and offer a smoother opening and closing experience, improving product longevity and user convenience. |
| Customization Capability | The 30x44 mm ROPP Aluminum Plastic Cap supports various personalized customization options, including embossed details, lithographic printing, UV printing, and hot stamping on the aluminum surface. Additionally, the plastic components’ color can be tailored to match brand requirements, achieving a high degree of color and brand image coordination. This customization capability enhances product visual appeal and further strengthens brand recognition in the market. |
