Plastic Screw Caps And Plugs

The integrity of a packaging system is only as good as its closure. Our plastic screw caps and plugs are engineered for high-torque applications, maintaining a perfect seal at 0.5 to 1.5 N·m of force. We use a variety of high-performance resins, including PP, PE, and LDPE, depending on the chemical resistance and flexibility required for your specific application. Our caps feature a tamper-evident ring that breaks on first opening, providing essential security and peace of mind for both the manufacturer and the end consumer.

Precision is our hallmark. With 16 years of injection molding experience, we maintain extremely tight tolerances to ensure that our plastic screw caps and plugs fit perfectly onto your bottles every time, preventing cross-threading and leaks. We conduct 100% visual checks for "short shots" or cosmetic defects and functional tests to ensure the tamper-evident band performs correctly. Backed by a 2-year warranty and a monthly production capacity of over 5 million injection-molded parts, we are your reliable partner for high-volume closure solutions.

Widely used for cosmetic bottles, pharmaceutical containers, household cleaning products, and industrial chemical jugs.

We offer a vast library of standard sizes (18/410, 24/410, 28/400, etc.) and can develop custom molds for unique cap designs in 15-25 days. Our factory features 13 high-speed injection molding machines and automated assembly for integrated plugs and caps.

Caps are bulk-packed in PE bags inside heavy-duty cartons to ensure cleanliness. We support FOB, EXW, and DDP terms.
