A plastic bottle is a bottle constructed from high-density or low density plastic. Plastic bottles are typically used to store liquids such as water, soft drinks, motor oil, cooking oil, medicine, shampoo, milk, and ink.
The size ranges from very small bottles to large carboys. Consumer blow moulded containers often have integral handles or are shaped to facilitate grasping.
Plastic was invented in the 19th century and was originally used to replace common materials such as ivory, rubber, and shellac Plastic bottles were first used commercially in 1947, but remained relatively expensive until the early 1950s when high-density polyethylene was introduced.
They quickly became popular with both manufacturers and customers because compared to glass bottles, plastic bottles are lighter, cheaper and easier to transport. However, the biggest advantage plastic bottles have over their glass counterparts is their superior resistance to breakage, in both production and transportation.
Except for wine and beer, the food industry has largely replaced glass bottles with plastic bottles.
The materials used in the manufacture of plastic bottles vary by application.
Petrochemical resins
High-density polyethylene (HDPE)
HDPE is the most widely used resin for plastic bottles. This material is economical, impact resistant, and provides a good moisture barrier. HDPE is compatible with a wide range of products including acids and caustics but is not compatible with solvents. It is supplied in FDA-approved food grade. HDPE is naturally translucent and flexible. The addition of color will make HDPE opaque, but not glossy. HDPE lends itself to silk screen decoration. While HDPE provides good protection at below freezing temperatures, it cannot be used with products filled above 190 °F (88 °C) or products requiring a hermetic (vacuum) seal.
Fluorine-treated HDPE
These bottles are exposed to fluorine gas in a secondary operation, are similar in appearance to HDPE, and serve as a barrier to hydrocarbons and aromatic solvents.
Fluorine-treated bottles may contain insecticides, pesticides, herbicides, photographic chemicals, agricultural chemicals, household and industrial cleaners, electronic chemicals, medical cleaners and solvents, citrus products, d-limonene, flavors, fragrances, essential oils, surfactants, polishes, additives, graffiti cleaning products, pre-emergents, stone and tile care products, waxes, paint thinner, gasoline, biodiesel, xylene, acetone, kerosene and more.
Low-density polyethylene (LDPE)
LDPE is similar in composition to HDPE. It is less rigid and generally less chemically resistant than HDPE, but is more translucent. LDPE is used primarily for squeeze applications. LDPE is significantly more expensive than HDPE.
Polyethylene terephthalate (PET, PETE) / Polyester
This resin is commonly used for carbonated beverages, water bottles, and food packaging. PET provides very good alcohol and essential oil barrier properties, generally good chemical resistance (although acetones and ketones will attack PET), and a high degree of impact resistance and tensile strength.
The orienting process serves to improve gas and moisture barrier properties and impact strength. This material is not resistant at high temperature. Its maximum temperature is 200 °F (93 °C).
Plastic bottles are typically used to store liquids such as water, soft drinks, motor oil, cooking oil, medicine, shampoo, milk, and ink. The size ranges from very small bottles to large carboys.
