HAOMEI Aluminum manufactures durable aluminum ROPP caps designed for spirits, wines, and beverages, with customizable options for colors, liners, and branding to suit a wide range of applications.
ROPP Closures and Specifications
ROPP (Roll-On Pilfer-Proof) closures are aluminum caps known for their tamper-evidence and excellent sealing properties. These closures are applied using capping machines, which roll the threads onto the bottle neck to ensure a tight fit, preventing leakage and contamination.
Material: Made of aluminum, offering durability, lightweight properties, and full recyclability.
Tamper-evident: Designed to show visible signs once the seal has been broken.
Customization: Available in a wide range of colors, sizes, and branding options to enhance aesthetics and brand identity.
Applications: Commonly used for sealing wine, spirits, water, and carbonated beverages.
Thread design: Engineered to perfectly match bottle threads, ensuring safe and consistent sealing.
Sustainability of Aluminum ROPP Caps
The sustainability advantages of aluminum ROPP closures include:
Recyclability: Aluminum is 100% recyclable, with relatively low re-melting costs and high reuse value, aligning with sustainable development goals.
Lightweight: Typical aluminum caps weigh only around 4 grams, helping reduce carbon emissions during transportation.
Durability and Protection: With strong sealing (leak-proof and tamper-evident), aluminum caps effectively protect the contents, minimizing waste from product spoilage or leakage.
Extended Shelf Life: Excellent barrier properties (against oxygen and moisture) help prolong product shelf life, indirectly reducing food and beverage waste.
Common Aluminum ROPP Cap Sizes
Wine: Most common sizes include 28x18mm and 30x60mm, specifically designed to fit standard wine bottles for perfect sealing.
Spirits: Popular sizes include 28x38mm, 30x35mm, and 33x47mm, tailored to different bottle capacities and neck designs.
