The expectation of modern packaging, functions, terms, and materials.

1. EXPECTATION OF MODERN PACKAGING,
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).
