Mineral water bottle cap is a plastic product, which is usually used to seal mineral water bottles or other plastic bottles. The raw materials for making mineral water bottle caps are mainly plastic materials such as polyethylene (PE) or polypropylene (PP), which are light, corrosion-resistant and easy to process, and are very suitable for making bottle caps.
The production process of mineral water bottle cap usually adopts injection molding technology. Injection molding is a molding method in which plastic raw materials are injected into a mold and cooled to obtain the required shape. Firstly, plastic raw materials are added into an injection molding machine and heated to a molten state; Then the molten plastic is injected into the mold, and the shape of the mold determines the shape and size of the bottle cap; Finally, after cooling and curing, the plastic is taken out of the mold to make the bottle cap.
Use of mineral water bottle cap
1, protect the bottle mouth: This is the most basic and direct use of mineral water bottle cap, which can effectively seal the bottle mouth to prevent water evaporation and bacteria from entering, thus keeping the water in the bottle clean and hygienic.
2. Prevent drinking by mistake: Different people have different needs for water, and some people may need to avoid some water sources. By using bottle caps, people can avoid drinking unclean water by mistake.
3, dustproof and moistureproof: mineral water bottle cap can prevent dust and humid air from entering the bottle, thus keeping the water clean and fresh.
4. Reduce evaporation: Due to the sealing function of the bottle cap, the evaporation of water can be reduced, thus reducing the waste of water.
