Water bottles are usually made of different materials, but the more common one is aluminum. The production of aluminum drinking water bottles starts with an extruder (single movement), through which cylinders can be made from aluminum discs.
Although aluminum is undoubtedly one of the more well-known water bottle materials, there are several others. Other materials used in water bottles are usually high-density polyethylene, low-density polyethylene, stainless steel, polypropylene, and copolyester. Compared with other containers, the use of aluminum bottles has many advantages. One obvious advantage of aluminum is its deodorization. In water bottles made of low-density and high-density polyethylene and polypropylene, the odor traces will remain longer and stronger than water bottles made of aluminum. Some other reasons people like aluminum bottles are that they are considered shock and deformation resistant, they protect water from light, and they are quite light. The coating inside the water bottle is also very flexible and is unlikely to crack or break due to impact. In addition, water and other beverages can be kept fresh and safe due to the safety helmet and inner coating.
In the 21st century, due to the vigorous promotion of environmental protection organizations, more and more people tend to reusable products. As we all know, aluminum drinking water bottles are harmless to the environment and ecology, which also makes them reusable. Almost 60 billion tons of plastic waste are generated every year. Through the use of aluminum bottles, these figures will reduce and avoid waste in plastic containers. Because many of these plastic containers will eventually enter the ocean and cause serious damage to marine life, aluminum bottles are also used. Besides, it also protects the ecological environment.
Aluminum bottles are widely used in shampoo and conditioner brands. Aluminum shampoo bottles are 100% recyclable, recyclable indefinitely, and are usually made of 68% post-consumer recycled (PCR) materials. High PCR content is important because the production of recycled aluminum bottles requires only 8% of the energy, just like the production of new aluminum, leaving much less waste. Although aluminum bottles are more expensive than plastic or glass, aluminum is lighter and less fragile, which is more suitable in a humid bathroom environment.
