Composite containers are made from more than one material like paper, boards, and metal or plastic ends. This enhances properties and minimizes weaknesses. There are different types of composite containers manufactured using convolute, spiral, or linear draw methods. Composite containers have advantages like being lighter, stronger, and more impact resistant than metal alternatives. They also have better environmental properties. Composite containers are widely used for food, pharmaceutical, and industrial products.

 Introduction to composite
containers
 materials used in it
 Diff types of composite cans
 Advantages
 Applications
 Environmental Responsibilities

3. Brief background
Global Economic Transformation: Agricultural and
Industrial.
a) Rigid and Costlier packaging are replaced by better,
convenient and cheaper ones.
b) Fortification by inexpensive materials.
c) Delicate components of multilayers can be buried
between other sturdy materials.
d) Today there are more than 100 plants making 7.6
billion composite cans

4. composite..
A composite container is a canister or
a container made from more than one constituent material
in order to enhances the maximize useful properties and
minimize their weaknesses , generally consisting of paper,
boards and Kraft papers with metal of plastic ends. It is also
called a ‘combican’.

5. .
Eg: One of the oldest and best-known
composites, glass-fibre reinforced plastic,
combines glass fibres (which are strong but brittle)
with plastic (which is flexible) to make a composite
material that is tough but not brittle.

7. There are basically some types of composite
materials which are used ..
• Fibre
• Flake
• Unbleached Kraft paper

8. Laminated Composite Container
1. These composite Container made from Kraft
papers and boards,
2. Laminated with polyethylene or aluminum
3. And heat sealed with the membrane and for
100% leak proof.
4. Unique properties: Aroma retention capacity
increases, permeability of moisture vapor
decreases.

9. Basic Structure of Composite Containers
Normally a composite container is made of five
components.
• The Liner
• The Body wall
• The Label
• The Bottom end
• The Top end

10. Different types of manufacturing
composite container
There are three types,
• Convolute method,
• Spiral method,
• Linear draw.

11. 1. In this method the web of papers of width of a can body is fed over
adhesive applicator and then on rotating mandrel.
2. A no of wraps from a tube.
3. Can produce square, oblong and oval shapes.
4. Can body is cut from master roll body, And tube is taken for labeling.
5. Widely used, cheaper, faster and economical.
Convolute Method

14. Spiral Winding Method
1. Layers of different qualities of papers are pulled over glue
rollers and on to a stationery mandrel at an angle and carried
around it by a moving belt to form a continuous tube.
2. It can produce only cylindrical shape.

16. Diff types of composite cans
• Peelable Foil Ends Container Easy Open End Container
Deep Lid Container

17. Quality Grades
Grade-I(Packaging Can): Tight enough for Lumpy
products, granules and
powder.
Grade-II(Instant Can): Tight enough for hydroscopic
products.
To prevent clog or caking.
Internal liner is heat sealed.

18. ADVANTAGES
The right mix of constituent materials often
results in composites which are corrosion
resistant. They can resists damage from
weather and harsh chemicals
composites are lighter in weight, compared
to most woods and metals. The lightness of
composites is important in automobiles and
aircraft, because less weight means better
fuel efficiency.
composites can be designed to be far
stronger than aluminium or steel.

19. o composites can be made to absorb
impacts like sudden force of a bullet or
blast from an explosion. Because of this
property, they are used in bulletproof
vests and panels and also to shield
airplanes, buildings from explosions.
o Combi cans can replace tin containers
since the latter are heavier, costlier,
corrosive and involve a foreign exchange
burden on the public exchequer.
o Composite containers are eco-friendly to
the environment because of its disposal
property as it can incinerate or crushed
for biological removal.

20. Cont…
• The stability of the can for a volume up to
1litre is as good are even better than tin or
glass container.
• 20% cheaper compared to tin.
• composites are durable and needs little
maintenance.

21. Minor problems..
• The joining of end closures with the sidewall
has problems.
• When the metal after curling, grips the joint
and wicking may be tightly around the seam,
biting into soft body ends may separate from
bodies during shipping. This happens during
stacking
• Wicking, skiving, tapering or cutting chances

23. Some other fields were composite materials are
used:
• Food products like Custard Powder, Masala
Powder, etc.
• Detergents, Detergent Powders.
• Pharmaceutical Products like Tablets, etc.
• Pesticides, etc.
• Laminated composite cans have replaced tin &
plastic containers for Motor oil, Grease, Inks,
Processed foods, Milk and Milk products

24. Cont..
• Jams/Jellies, etc.
• Fruit Pulps
• Fruit Beverages
• Preservatives
• Frozen Vegetables
• Canned bottled vegetables
• Milk Powder, Baby foods
• Lube oils, Motor Oil, etc.
• Tooth powder, Talcum powder, etc.
