PRIMARY PACKAGING:Contains food productSECONDARY PACKAGING:Holds several products togetherTRANSIT PACKAGING:Use for transportation of the product.

GLASSAdvantages:Cheap to produceConsumers can see the productcan withstand being filled with hot productrigidcan be recycledDisadvantages:Fragileheavy

METALAdvantages:Aluminium foil can be used to laminate and protect productcan be easily openedcan be recycledcan be used to preserve foodgood for reheatingfoil can be made in different thicknessDisadvantages:Can react with food and some cans need lining

PAPER AND CARDAdvantages: easily printed onBe produced in different thickness'Cheap to produceBiodegradableIf corrugated can protect and insulatecan be recycledeasily made into different shapes and sizesDisadvantages:Cant be squashedNot water resistant

PLASTICS:*lightweight*Cheap to produce*Cushion and protect food*easily printed on*Flexible or rigid*resistant to chemicals*Can be heat resistant*water resistant

THERMOPLASTIC PACKAGINGbecome soft when heated and can be shaped.

PP (polypropylene) (clingfilm)Can be flexible- prevents food drying outcan be rigid and withstand high temperatures

PVC (polyvinlchloride) (Mousse pot)Resistant to acidsCan withstand high temperaturesResistant to chemicalsFlexible

PS (Expanded polystyrene) (Take away pot)Protects food with cushioning effectGood heat insulation

PET (polyester) (ready meal lid)Can be used as filmideal for drinkshigh melting point so suitable for microwaves
