5 Gallon Water Jug Cap

The five gallon bottle cap, as the core sealing component of bottled water packaging, focuses on high reliability sealing, adaptability, and safety. It is designed specifically for the storage, transportation, and end use scenarios of 18.9L (5-gallon) bottled water, as follows:

High pressure sealing and leakage prevention: Adopting a multi-layer sealing structure (such as inner plug+threaded double seal), it fits tightly and can withstand the stacking pressure and transportation vibration of bottled water, effectively blocking the invasion of air, dust, and microorganisms, ensuring fresh water quality.

High toughness and impact resistance: Made of food grade HDPE raw material, the material is tough and resistant to impact and compression during transportation, avoiding bottle cap damage that may cause water leakage or pollution, and reducing supply chain losses.

Compatible with general equipment: adopting standardized thread design, it is compatible with mainstream five gallon barrel mouth (such as 55mm caliber) and automatic capping equipment in the industry, and can be quickly put into operation without the need to modify the production line, improving filling efficiency.

Convenient terminal use: Some styles have built-in one-way exhaust valves or are compatible with drinking water dispenser tube structures, which not only facilitate user installation and use, but also prevent secondary pollution, making them suitable for commercial drinking water scenarios such as homes and offices.

Food grade material certification: Made of 100% new food grade HDPE raw materials, free of harmful substances such as BPA and plasticizers, certified by authoritative authorities such as SGS and FDA, it can directly come into contact with drinking water and meets food packaging safety standards.

Hygiene protection design: Some products come with dust covers or disposable tear off seals, and undergo aseptic treatment before leaving the factory to avoid contamination during transportation and storage, ensuring hygiene and safety before opening.
