Inner diameter 20mm

We are a professional producer of pharmaceutical packing materials. My main products are aluminum caps, aluminum-plastic caps, flip off caps, polyprorylene caps for plastic infusion containers & nozzles for plastic bags.

Description: After pulling the plastic cap, when disinfecting with cotton swab, the threads of cotton won't remain attached to the aluminium cap.

We can put customer's logo on our caps, and any color, you can choose.

We have a lab and can make any color according to customer's requirements.
