20mm Non-Tear Twist Cap: A Durable Choice for Industrial-Grade Sealing

In the field of container packaging that requires long-lasting sealing and repeated opening, the 20mm non-tear twist cap has become the preferred solution for industries such as food, pharmaceuticals, and chemicals with its innovative design that abandons the traditional tear-off structure. With a standard diameter of 20mm, it is suitable for large-capacity containers like metal drums, plastic cans, and glass reagent bottles. The pure screw-on structure enables tool-free installation. Compared with tear-off caps, it is more suitable for scenarios that require frequent opening and closing or long-term storage, significantly reducing the packaging damage rate.

Durability: Industrial-Grade Standards for All-Scenario Protection

Impact Resistance Test: During a 1.5-meter drop test, there are no cracks at the joint between the cap and the container, and the sealing ring does not shift.
Pressure Resistance: It can withstand an internal air pressure of 60kPa without leakage, with a sealing strength 30% higher than that of similar tear-off caps.
Chemical Resistance: Made of acid- and alkali-resistant PP-H copolymer material, it does not swell or deform when in contact with chemicals such as acetone and sodium hydroxide.
