Description
Aluminum Screw Cap 28mm Resealable with Food-Grade Plastic Liner for Beverage
Premium aluminum screw caps engineered for standard screw-thread glass beverage bottles and mineral water bottles. Crafted from high-grade, lightweight aluminum, these closures offer outstanding rust prevention and superior corrosion resistance. Inside, the cap is fitted with a specialized food-grade plastic liner (PE/Saranex) that provides an airtight, leak-proof barrier, preserving the freshness, flavor, and carbonation of the beverage.
Featuring a precision-threaded design, this cap allows consumers to effortlessly open and reseal their drinks, making it an eco-friendly and premium alternative to traditional plastic caps.

Precautions
Capping Machine Torque Control:
Because aluminum is a relatively soft metal, ensure your automated capping heads are calibrated with correct torque settings (typically 1.2 to 1.8 N*m for a 28mm cap). Excessive torque can strip the internal threads or deform the aluminum shell, while insufficient torque will compromise the seal and cause liquid or gas leakage.
Pasteurization & Hot-Filling Temperature Limits:
Our standard aluminum caps and food-grade plastic liners are suitable for hot-filling up to 85°C (185°F) and standard beverage pasteurization. If your production line utilizes high-temperature sterilization/autoclaving above 100°C (212°F), please notify our engineers in advance so we can apply high-temperature-tolerant lacquers and specialized liners.
Strict Storage Environment Guidelines:
Store bulk stock of aluminum caps in a dry, well-ventilated warehouse with relative humidity kept below 60% and away from acidic or alkaline chemical vapors. Direct exposure to rain, extreme humidity, or damp warehouse floors can cause surface oxidation (white spotting) on unlacquered aluminum edges.
Glass Bottle Thread Compatibility:
Our aluminum caps are manufactured to strict international specifications (such as GPI/GCMI standards). Please ensure your glass bottles match these exact thread profiles. We highly recommend sending your glass bottle neck drawings to our technical team to perform a physical seal test before initiating mass production.
