This document presents information on food packaging materials. It discusses the definition of food packaging and requirements for packaging such as protection, shelf life, and being recyclable. The major packaging materials discussed include paperboard, polyethylene, laminated materials, glass, tin, aluminum, plastic, bamboo, jute, and wood. Properties, uses, advantages and disadvantages of each material are described. Primary, secondary and tertiary containers are defined. The document also addresses how packaging influences food shelf life and considerations for safety and the environment.

5. What is food packaging?
 Packaging can be defined as a method to protect and contain the food
with the aim of environmental impact of our consumption.
 The Packaging Institute International(PII) defines packaging as the
enclosure of products, items or packages in a pouch, bag, box, cup, can,
tray, tube, bottle or other container form to perform one or more of the
following functions: Containment , protection, preservation,
communication, utility and performance. If the container perform one or
more of the these function, it is considered as package

11. Paper board

12. Properties of paperboard

13. Advantage and Disadvantage of paperboard

14. Polethylene
Polyethylene is a polymer of ethylene(-CH2=CH2-). It is used as
packaging materials popularly in Bangladesh.
Polyethylene

15. • Polyethylene consists of nonpolar, saturated, high molecular weight
hydrocarbons.
• Polyethylene absorbs almost no water.
• The gas and water vapor permeability (only polar gases) is lower than for most
plastics; oxygen, carbon dioxide and flavorings on the other hand can pass it
easily.
Chemical properties of polyethylene

16. • Low Density Polyethylene (LDPE) e.g. Milk carton lining
• High Density Polyethylene (HDPE) e.g. Food packaging plastics
• Linear Low Density Polyethylene (LLDPE) e.g. Stretchable films
Classification of polyethylene

17. Advantage and disadvantage of polyethylene

18. Laminated Packaging Materials

19. Glass bottles

20. Tin cans

21. Aluminum cans

22. Plastic cans

23. Plastic cans

24. Aluminum foil
Aluminum foil is made by rolling pure aluminum metal into very thin sheets,
followed by annealing to achieve dead-folding properties (a crease or fold
made in the film will stay in place), which allows it to be folded tightly.

25. Advantage and disadvantage of aluminum foil

26. Bamboo(Eco-friendly)

27. Jute

28. Wood(crates)

29. Advantage and disadvantage of Wood packaging

30. Types of Packaging

31. Primary, Secondary and Tertiary Container

32. The shelf life of a food is controlled by three factors:
1. Product characteristics, including formulation and processing
parameters (intrinsic factors)
2. Environment to which the product is exposed during distribution
and storage (extrinsic factors)
3. Properties of the package.
4.Packaging also increases shelf life of food.
Effect of packaging on shelf life of food

33. Environmental consideration of food packaging
If we can decompose or recycle the packaging materials, our environment will be
safe from pollution…..

34. We can also save our planet through the use eco
friendly packaging materials…

35. Losses of nutrient during and after
packaging
The main factors that affect nutrient loss include- Light, Oxygen,
Moisture, PH, Heat.
Nutrient loss during packaging
 Packaging with heat denature proteins and destroy trypsin and
amylase inhibitors in green peas and beans
 Heat packaging also destroy thiaminase
 Losses in protein bioavailability
 Non enzymatic browning may also produce undesirable flavors and
texture

36. Losses of nutrient after packaging
 Fats of food in the presence of air also promote oxidation and
rancidity
 Water soluble vitamin especially vitamin-c and thiamine may be
losses after packaging
 Mineral matter may also decrease
