PLASTICS - TYPES
Plastic Applications
High density
polyethylene
HDPE Relatively rigid with high glossy finish
Uses include crates, drums, bottles and oil containers
May be used for frozen foods 30oC, also milk
Low density
polyethylene
LDPE Flexible plastic used for thin films – plastic bags, shrink wrap and food
protection
Most common form of plastic packaging
May be used for frozen foods 30oC
Polypropylene PP Can be stretched as a clear film or injection mounded for containers
Can be filled at high temperature120oC
May be used for frozen foods 30oC, biscuits / crisp wrappers, sauce bottles
Polyvinylchloride PVC Widely used (juices and mineral water). Flexible, heat resistant,
impermeable to gas and water and resistant to chemicals and acids.
Food safety concerns re use of plasticisers.
Polystyrene Typically used for cushioning and protection
Excellent heat insulation properties (containers for frozen food)
Polyethylene
Terephthalate
PET Similar to PP. Ideal for food and drink applications and possesses some of
the barrier and clarity properties of glass. High processing melting point –
makes it ideal for microwave applications.
Polyurethane Mainly used for packaging, cushioning and protection

Relatively cheap
Extremely versatile & readily available
Different processing methods permit a huge range of forms
Highly competitive against other materials
Extremely lightweight
1 litre glass bottle 700g vs. plastic 70g
Readily coloured for branding purposes
Excellent for protection of food
