22mm Large-Diameter Straw Tube Cap for Milk Tea - China Suppliers and Factory for Durable Plastic Solutions

20mm Non-Tear Twist Cap: The Ultimate Durable Solution for Industrial Sealing

The 20mm non-tear twist cap is revolutionizing container packaging in industries such as food, pharmaceuticals, and chemicals. As a leading choice among suppliers in China, this innovative cap design moves away from traditional tear-off structures, making it ideal for applications requiring reliable and long-lasting sealing. With a standard diameter of 20mm, it is perfectly suited for large-capacity containers, including metal drums, plastic cans, and glass reagent bottles. The pure screw-on mechanism allows for easy, tool-free installation, making it a hassle-free option for factories. Unlike conventional tear-off caps, this twist cap is built for scenarios demanding frequent access and long-term storage while significantly minimizing packaging damage rates.

Product Details

Durability: Industrial-Grade Standards

🛡️ 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.

Product Advantages

📍 ① Application Scenarios and Customization

In the food processing industry, this twist cap is suitable for containers used in sauce and cooking oil storage. Food-grade silicone sealing rings can be customized to ensure the safety of food storage. In the pharmaceutical storage field, for powder raw materials and reagents, versions with sterile certification and anti-static treatment are provided. In the chemical raw materials industry, special sealing rings and conductive coatings are equipped to effectively cope with the corrosion risks of chemicals.

🌿 ② Environmental Protection and Cost Advantages

Made of 100% recyclable PE/PP materials, it reduces plastic consumption by 25% compared with tear-off caps. The tool-free installation saves labor costs on the production line, and the standardized design of the screw-on structure keeps the defective rate below 0.3%. From materials to performance, it fully meets the requirements of industrial-grade sealing for long-term storage and repeated use.
