Plastic is the most common material used for the manufacture of bottles, cups and other containers. This type of bottle can be made of three major types of plastic; polyethylene (PE), polypropylene (PP) and polystyrene (PS). Many plastic bottles are made with a combination of these three plastic types, referred to as 'cross-bend plastics'. The best quality bottles are those that use polypropylene as their main plastic ingredient.
It was in the 1960's when the first Polypropylene Bottle was introduced. Since then, the demand for such plastic has increased tremendously. Plastic manufacturers have introduced varieties of plastic bottles ranging from food to medical ones. With a huge demand for plastic bottles, many manufacturers have also ventured into the production of wholesale plastic bottles.
Wholesale plastic bottles are available at a wholesale rate along with various other products. In general, the plastic bottle manufacturer offers different products in several categories like water, soup, oil, soaps, detergents, lubricants, paints, paper etc. There are some manufacturers who offer plastic bottles to suit every purpose. Their products include food, chemical, medical, baby, decorative, home, personal, bakery and spa plastic bottles.
Manufacturers use a series of techniques to manufacture plastic bottles. Some of them employ direct injection molding, which uses plastic pellets in high pressure to create the desired shape of the bottle. These plastic pellets are heated until they fuse to the plastic extrusion manufacturers. After cooling down, these pellets are manually removed from the mold, washed and re-cycled. Other techniques used by manufacturers include injection molding and tumbl printing.
In terms of sizes, there are various plastic bottles available in the market. Small, medium and large plastic bottles are manufactured for domestic and commercial purposes respectively. The most popular types of plastic bottles are water bottles, plastic food containers, soft drink bottles, gas cylinders, plastic ice cream and water bottles. Water bottles are manufactured using high pressure polyethylene and they are available in various colors such as blue, clear, dark blue, dark green, pink, yellow, orange, red, white and violet. Water bottles which have low emission allow the environment to retain the essential oxygen in the air.
It is very important for manufacturers to take care while manufacturing these plastic bottles and Plastic Injection. Since the bottle is used daily to drink, it is extremely important to manufacture water bottles that do not contain any harmful chemicals. These bottles should not contain bisphenol A (BPA), phthalates and formaldehyde. Other harmful chemicals in the bottle include benzene, atrazine, ethylenediamine, halogenated vegetable oil, methylene chloride and trihalomethane (THM). Manufacturers must therefore avoid using these chemicals in their products to ensure safe consumption of the products.
