HAOMEI Aluminum produces high-quality 28mm tamper-evident ROPP aluminum closures with PE liners, designed for bottled beverages. These closures are resealable and available in various heights such as 15.4mm, 15.9mm, and 16mm. We offer liner options including PE and TPE, resistant to temperatures up to 80°C, suitable for hot-filling, cold-filling, and pasteurization processes.
The Hidden Power of the PE Liner: More Than Just a Seal
PE (Polyethylene) is a common, cost-effective plastic material known for its flexibility and chemical resistance. In closures, it comes into direct contact with the bottle mouth, playing a crucial role in sealing the contents and preventing leakage or air ingress.
Key Advantages of PE Liners
High Seal Integrity: Soft and adaptable, PE liners fit tightly to the bottle’s rim, effectively preventing leaks and vapor escape.
Food-Grade Safety: Compliant with FDA and EU standards, odorless, non-reactive, and migration-free—ideal for beverages, pharmaceuticals, and sensitive liquids.
Chemical Resistance: PE resists alcohol, acids, and alkaline substances, ensuring compatibility with various liquid contents.
Cost-Effective: A highly economical liner solution without compromising performance.
