Plastic Options

PP: Polypropylene

The ‘workhorse’ of the plastics industry, polypropylene is one of the high-volume “commodity” thermoplastics. It has low density, is fairly rigid, has a high heat distortion temperature of up to 95°C (making it suitable for “hot-fill” packaging applications), and excellent chemical resistance and electrical properties.

COPP: Co-polymer Polypropylene

This is a specially modified highly transparent polypropylene random copolymer with medium melt flow, intended for injection moulding and injection stretch blow moulding. In addition to these properties, COPP is the best material for active hinges.

PE: Polyethylene

A thermoplastic material composed of polymers of ethylene. Polyethylene is the most widely produced polymer available in various densities.

HDPE: High Density Polyethylene

Its comparatively high density gives HDPE high stiffness, good temperature resistance and very good water vapour barrier properties.

LDPE: Low Density Polyethylene

Commonly used for reducer plugs in packaging, or can be blended with HDPE to adjust overall density.

LLDPE: Linear Low Density Polyethylene

Typically used for tubes, LLDPE is a material that is slightly stiffer and more stable than LDPE. It is also less prone to warpage and distortion on thin section mouldings.

PET: Polyethylene Terephthalate

PET plastics are clear in appearance and are available in a range of colours. Although lightweight, PET is tough and a good defence to gases and liquids. It is also highly resistant to dilute acids, oils and alcohols.

PETG: Glycol – Modified Polyethylene Terephthalate

This is a durable material with an excellent gloss, clarity and sparkle that makes for very clear bottles. PETG can be processed via conventional extrusion blow-moulding methods, generally on machines designed to process PVC. It is popularly used for shampoos, soaps, and detergents. The chemical resistance of PETG is fair, but compatibility testing is recommended, especially with products that contain alcohol.

PCTG: Poly – Cyclohexylenedimethylene Terephthalate Glycol

This co-polyester material is similar to PETG and can be processed in the same manner. It has better chemical resistance and is generally easier to process than PETG. It can also create larger capacity and heavier weight containers through extrusion blow moulding processes than with PETG.

PVC: Polyvinyl Chloride

A thermoplastic material composed of polymers of vinyl chloride, PVC is a colourless solid with outstanding resistance to water, alcohols, and concentrated acids and alkalis. It is used in unplasticised form for the production of containers such as liquid hand soaps, shampoos and bubble baths.

BDS: Butadiene – Styrene Block Copolymer

Has the clarity of SAN, but with the addition of an impact modifier. This allows moulding to flex without fractures.

SAN: Styrene – Acrylonitrile Resins

The SAN copolymer generally contains 70 to 80% styrene and 20 to 30% acrylonitrile. This combination provides higher strength, rigidity, and chemical resistance than polystyrene, but it is not quite as clear as crystal polystyrene and its appearance tends to yellow more quickly.

PS: Polystyrene

Protects against moisture and maintains its strength and shape even after long periods of time. Offers high clarity and rigidity.

PCR: Post Consumer Recycled Material

With the increased awareness of protecting the environment and consumer awareness for the need to recycle, we’re able to offer Post-Consumer Recycled material, which is re-used, broken down plastic bottles and containers. PCR can be offered between 25 -100% in PET and HDPE, These can be used for blow moulding and extrusion processing requirements. Where PCR cannot be used for technical reasons PIR (Post Industrial Regrind) is available.

Please note: There are many grades of each material and these are to be used as a guide only. We strongly recommend you carry out your own tests to approve material compatibility.

The Plastics ID Code identifies the type of plastic resin from which a product is made. The Society of the Plastics Industry introduced the system in 1988 in response to demands for easier recycling of post consumer plastics. The code was therefore developed to help recyclers by providing manufacturers with a uniform system. Since 1988 a wide range of plastics has been developed which are not covered by an individual number – these plastics are identified within the “7 other” classification. Berry Distribution adopt this system as it is the only globally recognised system available.
