The 33*47 mm aluminum-plastic anti-theft ROPP cap is a common bottle cap specification, mainly used for sealing products such as alcoholic beverages, carbonated and non-carbonated drinks, as well as pharmaceutical and healthcare products. It is made of aluminum-plastic composite material and features an anti-theft ring and sealing structure, effectively preventing tampering and counterfeiting to ensure product quality and safety.
In practical applications, the specifications and dimensions of the aluminum-plastic anti-theft cap can be customized according to the specific requirements of customers, such as surface decoration, hot stamping, or printing. This type of cap is suitable for mid-to-high-end alcoholic packaging, offering excellent anti-counterfeit performance and aesthetic appeal.
Structure of Aluminum-Plastic Anti-Theft ROPP Cap
1. Aluminum Alloy Shell
The aluminum alloy shell is made of high-quality aluminum alloys, such as 8011-H14 and 3003-H16. It is the critical part of the aluminum-plastic cap, determining the overall height and inner diameter, ensuring a tight fit with the bottle to prevent loosening.
Functions:
a. Provides structural strength and protects the internal sealing layer.
b. Can be printed with logos, offering corrosion resistance and recyclability.
Processing Requirements:
High-precision rolling is necessary to ensure a smooth surface without roll marks or scratches, suitable for automated production lines.
2. Plastic Liner (PVC-Free Liner)
This is the upper component of the composite cap, made of PE (Polyethylene) or PP (Polypropylene), which is non-toxic and has good elasticity.
Functions:
Forms a sidewall seal with the bottle mouth to prevent liquid leakage.
Resistant to high-temperature sterilization, suitable for the special process requirements of pharmaceuticals or beverages.
3. Anti-Theft Ring
Connected to the cap body by 16 small connection points (width: 0.7 mm, thickness: 0.5 mm). It breaks or deforms upon the first opening, ensuring the integrity and safety of the packaging.
