- 7. What is Food Packaging? -is packaging of food which requires protection, tampering resistance, and special physical, chemical, or biological needs.
- 8. Packaging should provide thecorrect environmental conditions for food starting from the time food is packed through to its consumption.
- 9.
- 10. Leaves Banana leaves areoften used for wrapping certain types of food.
- 11. Vegetable Fiber These includebamboo, banana, coconut, and cotton fibers. These natural materials are converted into yarn, string or cord which will form the packaging material. COCONUT FIBER
- 12. Wood offers goodprotection, good stacking characteristics and strength. Wood
- 13. Paper The degree ofpaper re-use will depend on its former use, and therefore paper that is dirty or stained should be rejected. • An inexpensive packaging material. • However highly absorptive, fairly easily torn, and offers no barrier to water or gases.
- 14. Earthenware used worldwide forstoring liquids and solid foods Next Slide
- 15. Glass Glass has manyproperties which make it a popular choice as a packaging material: • Glass is able to withstand heat treatments. • Protects the food from crushing and bruising. • Re-usable, re-sealable and recyclable • Transparent, allowing products to be displayed. Colored glass may be used either to protect the food from light or to attract customers.
- 16. Plastics The use ofvarious plastics for containing and wrapping food depends on what is available.
- 17. Metal • They providetotal protection of the contents. • They are tamperproof. • They are convenient for presentation.
- 18. Why we shouldhave good packaging? Provide a barrier against dirt and other contaminants 01. Prevent losses 02. Protect food against physical and chemical damage 03. Provide protection and convenience in handling and transport 04.

Editor's Notes
- #5 It also shows in the product label any nutrition information on the food being consumed.
- #7 It also shows in the product label any nutrition information on the food being consumed.
- #8 The main aims of packaging are to keep the food in good condition until it is sold and consumed, and to encourage customers to purchase the product. Correct packaging is essential to achieve both these objectives.
- #10 They do not however protect the food against moisture, oxygen, odors or micro-organisms, and therefore, not suitable for long-term storage. Can you give an example of leaves packaging materials? Who can give an example of foods that are being wrap with a leave?
- #11 As with leaves, vegetable fibers do not provide protection to food which has a long shelf-life since they offer no protection against moisture pick-up, microorganisms, or insects and rodents.
- #12 Wooden shipping containers have traditionally been used for a wide range of solid and liquid foods including fruits, vegetables, tea and beer. Have you seen a wooden box in the market?
- #13 Can you give example of paper packaging materials? We have already an act of no policy. When buy their it’s our responsibility to bring our own bag.
- #14 Example POTS. Do you have pot in your home?
- #15 Disadvantages of using glass as packaging materials glass is heavier than many other packaging materials and this may lead to higher transport costs it is easy to fracture, scratch and break if heated or cooled too quickly potentially serious hazards may arise from glass cracks or fragments in the food.
- #16 Plastics are extremely useful as they can be made in either soft or hard forms, as sheets or containers, and with different thickness, light resistance, and flexibility.
- #17 Disadvantages of metal food packaging materials: they are heavier than other materials, except glass, and therefore have higher transport costs the heat treatment associated with the use of metal cans is not suitable for small-scale production. What is the example of metal packaging?
- #18 keeping the product clean For example, packages should be securely closed to prevent leakage For example the harmful effects of air, light, insects, and rodents. Each product will have its own needs
