= **Packaging of Food and Beverage** =

Various types of packaging are used to house our products, whether it is a can of soft drink to a container of left overs from last nights dinner. We put our food and drink into various housing but do you know what they put into that?

ALUMINIUM



Advantages: Offers a high level of corrosion resistance Optimal protection properties by offering a impermeable metal barrier to light, ultra violet rays, water vapour, oils and fats oxygen and microorganisms Hygienic, non toxic, non tainting & retains product flavour Keeps contents fresh (protections from external influences) The lightest complete barrier packaging material

Disadvantages: With acidic food, the acid reacts with the metal to cause an aluminium taste. Can’t see contents.

POLYETHYLENE TEREPHTHALATE



Advantages: Easily mouldable which allows individual bottle shapes Stable and lightweight Inexpensive &versatile Minimal substance transfers Recyclability – easily broken into monomers In terms of biopolymer productions, PET ranks last on environmental impact.

Disadvantages: Becomes brittle and opaque at increasing crystallisation levels When extremely crystallised, the bottle turns white Absorbs flavour components of beverage – the polymers molecules are tangles within each other like a sponge. Shorter shelf life

GLASS



Advantages: Chemically inactive (inert) Impermeable (doesn’t allowed fluid to pass through) Does not produce odour. Versatile (shape & colour) Reusable Suitable for use in microwave Excellent clarity

Disadvantages: Weakness – effects transportation Expensive Allows light & ultra violet rays through which effect products. Higher weight then alternative
