This document summarizes common packaging materials including tin-plated containers, tin-free steel cans, aluminum containers, glass containers, rigid plastic containers, flexible plastic packaging, and paper and cardboard. Tin-plated containers are made of low carbon steel covered with tin on both sides and are lightweight, rigid, strong, and corrosion resistant. They are used for packaging foods like spices, soups, and soft drinks. Tin-free steel cans are electroplated with chrome and used for packaging foods and beverages. Aluminum containers are an alternative to tin-plated cans and are also lightweight and used for packaging beverages and fish. Glass containers are chemically inert and used for packaging foods due to their

with chrome.
Eg: Can super, Hi-top, Mira
seam..etc.
For soft drinks, fruit juices, milk
powders, beers..etc.
Canning of fruits & vegetables.

5. Tin-free steel
cansAdvantages;
• Presence of chromium helps to prevent the rusting and
corrosion.

6. Aluminium
containers
•
•
•
•
•
Alternative for tin-plate cans.
Light weighted.
Contains 99.5% aluminium and small
amount of silicon, iron, zinc, titanium,
copper..etc.
Also used as bottle tops or closures.
Use to packing of beverages, fishes..etc.

7. Aluminium
Foils•

lamination purposes.
Also used for sealing fried fish and
meat products.
•
•
•
•
•
Uses of foils;
Tubes - condensed
milk Trays- frozen
foods
Product seals - sour cream, butter
& yoghurt
Wrappers – Covering of chocolate
block

8. Aluminium containers &
foilsAdvantages;
•
•
•
•
• Basic materials are available in abundant.
Easily fabricate, less chance of leakage.

1stplastic container was made by
cellulose acetate.
In the shape of bottles, cans, jars,
cups, tubes..etc.
Used for Pasteurized milk, non
carbonated mineral water, wine,
vinegar..etc.
Carbonated non-alcoholic
beverages are packed in PET made
containers.

12. Rigid Plastic
ContainersAdvantages;
•
•
•
•
Both transparent and non-transparent.
Very cheaper than others.
Good rigidity.
Recyclable.
Disadvantages;
•
•
•
Low heat stability than glass.
Manufacturing and wastage makes pollution.
May react with high acidic foods.

13. Rigid Plastic Containers

14. Flexible Plastic
PackagingRetortable pouches
•
•
•
•
•
Have a thickness up to 0.375mm.
Made by extrusion.
Alternative to metal cans and
glass containers.
Suitable for canning.
Used for thermally processed-
fruit, vegetable, meat & fish
products.
