20mm Plastic Screw Cap for Water Bag and Juice Pouch - Reliable China Suppliers & Factory Solutions
Key product advantages include
This twist cap innovatively integrates the single-clamp and screw-thread designs. During use, the cap is first quickly positioned and clamped to the bottle mouth through the single-clamp structure. Then, by rotating the twist cap, the fine threads tightly engage with the bottle mouth, ensuring the sealing effect with a dual guarantee. This design has significant advantages in complex environments. During food transportation, it can prevent leakage of sauces and cooking oil even when facing bumps and vibrations.
In pharmaceutical storage scenarios, it can effectively isolate air, avoiding moisture and deterioration of drugs. When containing corrosive liquids in the chemical industry, it can also rely on its high-strength sealing structure to completely eliminate the risk of leakage. According to professional pressure tests, even under an external pressure of over 50kPa, the built-in thickened silicone sealing ring and the screw-thread structure work in tandem to remain completely leak-proof, comprehensively safeguarding the safety of the contents.
