What Material

PE - Polyethylene

These generally consist of HDPE (high density polyethylene) which will produce components with high stiffness, good resistance to water vapour and excellent resistance to alcohol, acids and alkali's.

PP - Polypropylene

Bottles blown using polypropylene will give excellent stress crack resistance, and excellent resistance to alkalis and acids. Typically used to create a more squeezable bottle.

PETG / PCTG - Polyethylene Terephthalate Glycol
» Read more about 'PETG/PCTG'

Bottles blown using PETG will give excellent stress crack resistance. PETG is used where very high clarity is required (comparable to a glass bottle).

PVC - Polyvinyl Chloride

PVC bottles will give very good resistance to alcohols, acids and alkalis. PVC is used where clear bottles are required.

PET - Polyethylene Terephthalate

Good barrier characteristics against carbon dioxide and oxygen, excellent clarity nearing that of glass and suitable for recycling.

PP - Polypropylene

Commonly used for the moulding of closures. Can offer good clarity and high impact resistance.

BDS - Butadiene Styrene Block Copolymer

This resin can be used where excellent clarity is required

LDPE - Low Density Polyethylene
» Read more about 'LDPE'

Primarily used in moulding reducer plugs as they require being flexible and when being used in conjunction with closures and bottles of a dissimilar plastic.

HDPE - High Density Polyethylene
» Read more about 'HDPE'

This material is used when additional moulded components are required ie base cups, as this will improve the recycling of the container as the component may be the same material as the container.
