Types of the raw material used by manufacturing plastic bottles


Plastic Bottle Packaging Australia is widely used for packaging for beverages, detergents, and other consumer items. Packaging is a new science and engineering area that contributes significantly to the pharmaceutical sector. Polyethylene terephthalate is used to make plastic bottles for filtered water and other beverages since the fabric is both strong and light.

Polyethylene is available in two densities such as high-density for small plastic bottles like detergent bottles and low-density for squeezing bottles. Tablet bottles are made of polypropylene, while refillable water bottles and other transposable containers are made of polycarbonate. For a better knowledge of the production process, it is beneficial to observe the material compositions.

High-density polyethylene:

The high-density polyethylene resin identification code can be challenges that plastic bottle packaging suppliers. It is the most often used material for plastic bottles because it is affordable and produces a well-organized moisture barrier. It is made of petroleum, a naturally occurring liquid found deep beneath the Earth’s surface in geological formations. Pipes, lumber, fireworks, and plastic bags are all made from it. Many solvents are resistant to HDPE, and it has a high density-to-strength ratio, making them ideal for reusable and recyclable bottles.

Polyethylene Terephthalate:

PET, PETE, or polyester is a strong and light plastic commonly used in carbonated beverages, water, and food products. PET, like other plastics, is manufactured from petroleum hydrocarbons, which are generated when ethylene glycol, a white viscous, hygroscopic liquid, reacts with Terephthalic acid, an organic chemical. PET polymerizes during the manufacturing process, resulting in lengthy molecular chains, and the Plastic bottle packaging suppliers supply it. The resin identification is found on a polyethylene Terephthalate plastic bottle.


Polypropylene can withstand high temperatures and is autoclavable, allowing for steam sterilization. It is noted for its versatility and suppleness, and it can be customized for a variety of uses. Polypropylene is chemically resistant and has a rough surface. It is also manufactured with good moisture barriers, and it comes in a variety of colours for easy identification.

Low-density polyethylene:

Low-density polyethylene is similar to HDPE in appearance, but it is less transparent, chemically resistant, and firm. The monomer ethylene is used to manufacture LDPE, which has resin identification. Plastic bottle packaging Australia is most typically used to make plastic bags. However, it can also be found in detergent, dispensing, and squeezable bottles for delicacies like honey and mustard.


The artificial aromatic polymer polystyrene is created from the monomer styrene, and the manufacturing bottle can be taken to the plastic bottle packaging Australia. It can be made of solid or foamed plastic that is rigid and has a good moisture barrier and low thermal conductivity. Polystyrene is frequently used to create bottles for dry goods like vitamins and aspirin. Some milk and yoghurt drinks come in PS bottles that can’t be used as solvent containers. As a result, using plastic bottles or bags is completely safe.

Polyvinyl Chloride:

When utilized in plastic bottles, this basic material is usually clear. Water, alcohols, alkalis, and many strong acids are all resistant to polyvinyl chloride, with predictable and long-term stability. It is ideal for solid tablet vials, tablet strips, and blister packs.
