22mm Large-Diameter Plastic Straw Cap for Milk Tea Jelly Drinks - China Suppliers and Factory Direct Quality
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.
Product Advantages
① Application Scenarios and Customization Options
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.
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, providing a reliable guarantee for scenarios that require long-term storage and repeated use.
