Modern packaging is expected to meet several requirements: it must protect contents from damage, not contain harmful chemicals, allow for easy identification, handling and disposal or recycling. It serves key functions like containment, information provision, preservation and protection. Common packaging terms include aseptic, breathing, retort and MAP packaging. Popular materials are metals, glass, paper, plastics and laminates. Each material has advantages - metals can preserve contents for long periods, glass allows visibility, paper is versatile, plastics are lightweight and rigid, and laminates combine strengths of different materials.

FUNCTIONS,TERMS, MATERIALS..
BY
MONISHA SELVAN

2. EXPECTATIONS OF MODERN
PACKAGING
 The packages must have
 Sufficient mechanical strength to protect
 Construction material must not contain chemicals.
 Must meet handling & marketing in terms of
weight,size,shape.
 Allow rapid coding of the contents.

3.  Security of the package.
 Should identify its contents.
 Required to aid retail presentation.
 Designed for easy disposal,reuse,recycling.
 cost should be less.

4. FUNCTION
CONTAINMENT:
 packaging needed to contain a product depends on the physical
form of the product and the nature of the product itself.
.
 For example, a corrosive chemical needs to be contained in a pack
that does not allow the chemical to leak, react with its surroundings,
react with its packaging

5. PROVIDING INFORMATION ON A PRODUCT:
 communicating information on a pack to a consumer.
 Helps to identify and market the product,
 legal requirements as to the information a pack must contain.
PRESERVATION:
 Inhibiting chemical and biological changes.
 This extending the shelf life of a food product beyond its natural life.
 Limits must be established so that packaging can be designed to
preserve a product to an acceptable level within these limits.

6. PROTECTION:
 guarding against physical damage.
 This could arise through shock, vibration or compression damage.
 Eg: corrugated cardboard boxes used for distribution packaging .
Sales:
 a pack must be effective in branding the product name using
enticing pack shapes, colours, designs, etc.
 These complementary skills are normally the preserve of the sales
and marketing team

7. PACKAGING TERMS
Aseptic packaging
 shelf-stable container by placing a commercially sterile product into
a container in a sterile environment.
 maintains product sterility until the seal is broken.
Breathing package
 air may enter or leave under varying conditions,
 including temperature changes, with or without a drying agent to
remove moisture from entering the package

8. Retort packaging
 a flexible container formed from aluminum foil and plastic laminants.
 withstand in-package sterilization of the product.
PET ("polyethylene terephthalate")
• a thermoplastic polyester used in beverage bottles and food trays

9. MAP ("modified atmosphere packaging")
 a combination of gases such as oxygen, CO2 and N2 is introduced
into the package at the time of closure.
 to extend shelf life of the product packaged.

10. Metal can
 steel sheet or plate, 27 gauge or less in thickness, or
 a similar container made of aluminum, copper or other metal.
(example: food cans)
Meat wrapping paper
 a specially treated odorless and tasteless paper that resists meat
juices, fat and grease, and
 It is easy to remove from any kind of meat.

11. Shrink wrapping
 plastic film that shrinks when heated, producing a tight, neat fit;
 the most popular form of grocery store ,meat packaging is PVC
wrapping with foam trays.
Ovenable board :
 a paperboard that can be placed in an oven to serve as the cooking
utensil for food;
 typically a solid, bleached sulphate board coated with polyester
terephthalate.

12. Vacuum packaging:
 all air has been removed before sealing.
 Carbon dioxide or nitrogen may be introduced into the container.
 This process prolongs shelf life, preserves the flavors and retards
bacterial growth.

14. Food Packaging Materials
 Metals (steel, tin, and aluminum) -- canned foods
 Glass -- beverages, pickles, condiments
 Paper (usually coated with wax, plastics, or aluminum foil) -- cartons
of milk, crackers
 Plastics -- milk jugs, beverages, deli salads
 Packaging films (cellophane, edible films, and coatings) -- candy
bars, hot dog casings, chips
 Laminates (layering materials into one product) -- drink boxes

15. Packaging Materials
Cans
Advantages:
 Cheap
 Provides good protection
 Easy to handle
 Stack easily on
supermarket shelves
 Store for long periods of
time

16. Glass Containers
Characteristics:
 Chemically inert
 Non porous,Odourless &
hygienic
 Contents can be seen as
glass is transparent
 Great strength
 Variety of shapes & sizes
 Long-term storage &
extended shelf-life
 Sustainable - can be
recycled or re-used

17. Paper & Cardboard
Paper:
 Used for a wide variety of
products
 Versatile & cost effective
 Variety of shapes, textures &
thickness' available
 Greaseproof paper can be
used when packaging
products such as
confectionary & butter.

18. Rigid Plastic Packaging
Advantages:
 Lightweight & strong
 High resistance to
breakage
 Available in a wide
variety of colours,
shapes, sizes & textures.
 Cheap and easy to
produce compared to
other packaging
materials

19. Aluminium Foils
Most foils made from aluminium
Advantages:
 Light,flexible
 Strong,Able to withstand
moderate heat
Examples:
Tubes - condensed milk

20. Laminations
Aluminium foil with other materials
such as plastic and paper to create
a stronger packaging material.
Example:
Muesli bar wrapper (paper,
foil & plastic).
