22mm Large-Diameter Straw Tube Cap for Milk Tea - China Suppliers & Factory Plastic Straw Screw Cap
Durability: Industrial-Grade Standards for All-Scenario Protection
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.
It can withstand an internal air pressure of 60kPa without leakage, with a sealing strength 30% higher than that of similar tear-off caps.
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
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 to ensure compliance with drug storage environmental standards. In the chemical raw materials industry, in response to the needs of containers for corrosive solvents and coatings, special sealing rings and conductive coatings are equipped to effectively cope with the corrosion risks of chemicals.
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, providing a reliable guarantee for scenarios that require long-term storage and repeated use.
The cap is designed to industrial-grade standards, passing a 1.5-meter drop test without any cracks at the joints or shifts in the sealing ring, ensuring safety during transit.
Yes, they can withstand internal air pressure of up to 60kPa without leakage, offering 30% higher sealing strength than standard tear-off caps.
Absolutely. The caps are made of PP-H copolymer material which is resistant to acids, alkalis, and chemicals like acetone and sodium hydroxide without deforming.
Yes, we offer customization with food-grade silicone sealing rings specifically for the food processing industry, including sauce and oil storage.
Our caps are made of 100% recyclable PE/PP materials and use 25% less plastic than traditional tear-off caps, significantly reducing environmental impact.
No, the standardized screw-on structure allows for tool-free installation, which helps reduce labor costs and maintains a low defective rate below 0.3%.
