30x60mm Aluminum ROPP Cap FAQs

How is the sealing performance of the 30x60mm ROPP aluminum cap?

HC Aluminum’s 30x60mm ROPP aluminum caps use specially designed liners and precisely machined threads to provide excellent sealing performance. Tests show no leakage within a pressure range of -0.08MPa to +0.3MPa, ensuring sealing integrity during normal storage and transportation. The choice of liner material also affects sealing performance. We offer a variety of liner materials, including PE, EPE, Tin-Saran, and Saranex, to meet different sealing requirements.

Is the opening torque of the aluminum cap moderate, ensuring both tamper resistance and ease of opening?

Yes. Our 30x60mm ROPP aluminum caps feature a specially designed tamper-evident ring structure, with an opening torque (breakaway torque) controlled between 1.5-4.0N·m. This ensures good tamper resistance while remaining easy for consumers to open. The connection points of the tamper-evident ring are reasonably designed to produce a noticeable breaking sound and visual indicator when opened. The aluminum cap can also be re-tightened after opening.

Can the aluminum cap withstand high-temperature sterilization processes?

Yes. Our 30x60mm ROPP aluminum caps can withstand conventional high-temperature sterilization processes, including moist heat sterilization (121℃ for 30 minutes) and dry heat sterilization (180℃ for 1 hour). After high-temperature sterilization, the aluminum cap shows no significant deformation or damage, and the sealing performance remains good. For applications requiring high-temperature sterilization, it is recommended to select high-temperature-resistant liner materials, such as Teflon or specially treated PE materials.

What types of bottle necks are suitable for the 30x60mm ROPP aluminum cap?

Our 30x60mm ROPP aluminum caps are mainly suitable for standard threaded bottle necks with a 30mm outer diameter, including both glass and plastic bottles. The applicable bottle neck types include: standard 30mm threaded necks, flat and slightly tapered neck designs. Tests show that our 30x60mm ROPP aluminum caps are compatible with over 95% of standard 30mm bottle necks on the market. For specially designed bottle necks, it is recommended to provide samples for compatibility testing.

Comparison: Screw Caps vs Corks

Oxidation Control: Screw caps outperform natural corks; reduce risk of cork taint.
Resealability: Easier to reseal than cork, more convenient for consumers.
