The water, as a product, comes in many different containers. One of the most common is a plastic bottle. If created from recycled plastics or ex-garrafas documents and materials, plastic water bottles are cheap and efficient.
The plastic used to create water bottles is commonly made from oil. The oil is refined into usable plastic in the form of pellets. Bioplastics, made from plants, provide a greener solution to petroleum-based plastics, but at the cost of shelf life. Many bioplastics degrade much faster.
Melt the plastic pellets technicians to form similar objects the test tubes called preforms. Each pré-molde is placed in a mould and a tube inserted into the opening. Using a mix of infrared and thermal heat, the pré-moldes are heated to the melting point. Once hot enough, the air is pumped through the tube, the expansion of the preform to fit the mold of plastic bottle. Once it is cooled, the bottle is released from the mold.
Green options for plastic bottles of water include reuse and recycling, according to aceinland. Sterilised jars can be reloaded and resold without the cost of manufacture. Recycling of plastic water bottles involves the destruction of old plastic bottles and sterilising the chips shredded.
