3. Tin-plate containers
• Low carbon steel covered with
tin on both side.
• Light weight.
• Rigid & strong.
• Corrosion resistant.
• Used for packing spices, soups,
soft drinks..etc.

4. Tin-plate containers
Advantages;
• More shelf life than normal metal containers.
• Easy to fabrication.
• Low weight, easy to handle.
• Easily handling on high speed sealing machineries.
Disadvantage;
• Limitations for packing acidic products.
• Not flexible in can shape.

5. Tin-free steel cans
• Electro plating of steel plate
with chrome.
• Eg: Can super, Hi-top, Mira
seam..etc.
• For soft drinks, fruit juices, milk
powders, beers..etc.
• Canning of fruits & vegetables.

6. Tin-free steel cans
Advantages;
• Presence of chromium helps to prevent the rusting and
corrosion.
• Suitable for attractive printing.
• High internal pressure resistance capacity.
• Suitable for low acid food products.
Disadvantages;
• Not suitable for soldering & Problems in welding.
• Can’t recycle or reuse.

7. 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.

8. Aluminium Foils
• Aluminium foils are used for
lamination purposes.
• Also used for sealing fried fish and
meat products.
• Uses of foils;Uses of foils;
• Tubes - condensed milkTubes - condensed milk
• Trays- frozen foodsTrays- frozen foods
• Product seals - sour cream, butter &Product seals - sour cream, butter &

• Wrappers – Covering of chocolate blockWrappers – Covering of chocolate block

9. Aluminium containers & foils
Advantages;
• Basic materials are available in abundant.
• Easily fabricate, less chance of leakage.
• Corrosion doesn't make any colour.
• Non toxic, not have a metallic taste.
Disadvantages;
• Require high energy to production.
• Cannot be welded or soldered.
• Tendency to bleach with some pigmented foods.
• Empty cans have transportation risk.

10. Glass Containers
• Chemically inert.
• Made by fusing of silicates &
oxides of sodium, calcium..etc
• Transparent.
• Great strength & heat stability.
• Long-term storage & extended
shelf-life.
• Used for milk products, fruit
products, pickles, sauces, marine
foods..etc.

11. Glass Containers
Advantages;
• Safe from contamination & health hazards.
• Easy to open and close.
• Transparent, It can reuse/recycle.
• Ideal for microwave.
• Varied shapes and colours.
Disadvantages;
• Heavy weight, have tendency to broken down.
• Disposal issues.
• Costly than Plastic containers.

12. Rigid Plastic Containers
• Made by PVC, HDPE, LDPE..etc
• 1st
plastic 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.

13. Rigid Plastic Containers
Advantages;
• 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.

15. Flexible Plastic Packaging
Retortable pouchesRetortable 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.

16. Flexible Plastic Packaging
Layers of retortable pouches

17. Plastic pouches
• Made by plastic films.
• HDPE used as cereal
bags.
• LDPE used as Kraft singles
wrappers.
• Polypropylene for chips,
biscuits, 2 minute noodle
wrappers..etc.
Flexible Plastic Packaging

18. Flexible Plastic Packaging
Advantages;
• Good shelf life.
• Easy to open pouch.
• Requires less storage space.
• Light weight.
• No metallic contamination.
• Easy to dispose.
Disadvantages;
• Consumes much packaging time.
• Affect overhead pressure.

19. Flexible Plastic Packaging

20. Paper & Cardboard
• Suitable for small-scale & bulk
packaging.
• About all kind of foods can be
packed using paper & its
products.
• Dry products like; cereals, breads,
biscuits.
• Powders like; coffee, tea, sugars.
• Liquid foods like; Juice, milk, soft
drinks.
• Fresh foods like; meat, fish, egg..etc
• Frozen foods like; butter, ice cream,
and other chilled products

21. Paper & Cardboard
Advantages;
• It can be used as bags, pouches,
wrappings, boxes, folding
cartons, drums, moulds, tetra
packs..etc.
• Presence of cellulose fibers give
good rigidity.
• Flexible and easily molded.
• Light weighted.
• Less expensive & widely
available.
• Cardboard cartons have high
shock resistive capacity.

22. Disadvantages;
• Non-laminated paper
packages may cause
damage due to moisture
contact.
• May cause damage on
transportation with out
external barriers.
• Most of paper packs
aren’t reusable.
