MATERIAL
CHARACTERISTICS
PAPER :
Kraft paper
 Brown, unbleachedpaper.
 Good strengthandresistant to
Bursting
 Economical
 Environmental-friendly
 Moisture-proof, water-proof, anti-oil
Immersion
 Easy to handle
 Recyclable
 Provides protectionagainst physical
Damage
 Holds the contents and keeps them
Secure till used
PAPER:
Grease-proof
paper
 High-density paper,
 Very smooth surface
 Has air permeability allowing the
food to breathe ,thus preventing a
rapid loss of flavor and visual appeal
 Impermeable tooil or grease
 Machine friendly for printing
 Highstrengthand stability
 Can be usedin ovenand freezer
 Easy to handle
 Holds the contents and keeps them
Secure till used
 Cost-effective
 Eco-friendly
PAPER-
BOARD
 Highthickness
 Suitable for printing
 Highstrength
 Light-weight
 Higher weight per unit area
 Can be easily cut and molded
 Resists impact, abrasionand
Compressiondamage
 Made from multiple layers
 Larger corrugation provides
Cushioning

3. GLASS
PACKAGING
 They are impervious tomoisture
Gases, odors, and microorganisms.
 They are inert and do not react
withor migrate intofood products.
 They are suitable for heat processing
When sealed.
 They are transparent tomicrowaves.
 They are reusable and recyclable.
 They are resealable
 They are transparent and display
 The contents.
 They can be moldedinto a variety
of shapes and colors.
Metal
container
packaging
 They have a high strengthto weight
ratio.
 They can be heat processed.
 They have excellent barrier and
protective properties.
 They produce shelf-stable productsth
at ambient temperature.
 They are tamperproof.
 When sealedwitha double-seam
they provide total protectionof the
contents,
 Ease of fabrication.
ALUMINIUM
FOIL
PACKAGING
 Good appearance
 Excellent dead-folding properties
 Ability toreflect radiant energy
 Excellent barrier tomoisture, gases,
and odors
 Nonabsorbent andnontoxic
 Highlevel of corrosionresistance
 Guarantees longer shelf life
 Light-weight
 Low transport costs
 100% recyclable
 Flexible, i.e. Canbe moulded into
Infinite number of shapes

4. PLASTIC:
POLYESTERS
(Polyethylene
Terephthalate)
PET BOTTLE
 Good barrier togases like O2 and Co2
 Longer shelf life
 Good resistance toheat,mineral oils,
solvents, andacids
 Retentionof carbonation
 Light weight
 Absorbs very littlewater
 Hard, stiff and dimensionally stable
 Easy to transport
 Recyclable and transport tomicrowave
Radiation
 Broad range of use temperature from
-60 C to 130 C
PLASTIC:
Polyolefins
Polypropylene
 Harder, denser
 Translucent
 Good resistance tochemicals
 Effective at barring water vapour
 Highmelting temp. makes it suitable
for applications where thermal
resistance is required
 Good fatigue resistance
 Highly resistance tochemical corrosion
 Resistant tomould, bacteria
 Waterproof
 Highinsulationproperties sousedin
Electrical goods and cables
PLASTIC:
POLYSTYRENE
 Clear, hard and brittle
 Low melting point
 Keeps food freshlonger
 Excellent thermal insulation
 Lightweight
 Easy to handle
 Colorless polymer usedfor lowcost
Applications
 Can be moulded or foamed to form
A range of products
 Provides protective barriertophysical
 Damage

5. PLASTIC:
LOW DENSITY
POLYETHYLENE
(LDPE)
 Transparent inthin filmforum
 Very low water absorption
 Excellent coldresistance upto -70 C
and so is used infrozenfood package
 Good resistance toalcohols, alkalis
 And acids
 Susceptible tostress cracking
 Low cost polymer
 Excellent electrical insulating property
 Moisture resistance
 Highly flammable
