- TYPES OF FOOD PACKAGING MATERIALS
- Foil – 0015 –
- Coasted sheets
i Foil – 0015
ii Laminates of one or more of the above materials
iii Coasted sheets
iv Films M.S.A.P (moisture resistant sealable anchors well to product, transparent)
v Metals such as tin plate, tinfree steel and aluminum
vi Plastics which including a variety of homogeneous films, coasted films, laminates with other plastics, papers or metals (eg aluminum)
vii Papers, paperboardsm fiber boards
viii Traditional. This cannot withstand rough handling but have no advertising potential and are not suitable in protecting the product in long distance distribution.
ix Industrial: This is where material is used for packaging of food widely by including cartons, cups boxes etc.
SELECTION OF PACKAGING MATERIALS
This depend intrinsically on natures and other properties of product and on the other consideration indicted above

- Moldable and pliable at low temperature
- Flavorless and tasteless
- Kesistant to scuffing and tearing
- High …. Strength
