1. Types of Food packaging materials K R MICRO NOTES 1

2. Packaging Packaging is an integral part which has major influence on , storage life marketability of products. It is pervasive and essential. It provides a barrier between the food and the environment. Packaging sector represents about 2% of GNP. K R MICRO NOTES 2

3. P r o t ection Convenience Containment Communication K R MICRO NOTES 3

4. Non-toxic and compatible with the specific foods Sanitary protection Moisture and fat protection Gas and odor protection Light protection Transparency Tamper-proof Pouring features Reseal features Ease of disposal Low cost Features of Packaging material K R MICRO NOTES 4

5. Primary containers are those containers which directly come in contact with food whereas secondary containers do not have direct contact with food materials. Some of the foods like milk, juices and fruit concentrates are generally filled into primary containers such as plastic liners which are further packaged within protective cartons or drums called secondary containers. Tertiary containers are generally used during shipping. They are used to unitize the secondary containers. Examples of such packaging containers are wooden boxes, drum, cartons etc. K R MICRO NOTES 5

7. Natural materials Natural materials . Baskets and other traditional containers are made from bamboo, rattan, straw, palm leaves etc. Disadvantages are: They are difficult to clean when contaminated with decay organisms. They lack rigidity and bend out of shape when stacked for long-distance transport. They cause pressure damage when tightly filled. They often have sharp edges or splinters causing cut and puncture damage. 7 K R MICRO NOTES 7

8. Types of Packaging Classification based on stages of distribution system for which it is primarily intended…. Consumer packaging Transport packaging K R MICRO NOTES 8

9. 1.Consumer packaging Bags : Paper bags Plastic bags K R MICRO NOTES 9

10. for long periods Plain paper is not used to protect foods because it has poor barrier properties and is not heat sealable. When used as primary packaging (i.e. in contact with food), paper is always treated, coated, laminated or impregnated with materials such as waxes, resins or lacquers. Kraft paper - package flour, sugar and dried fruits and vegetables. Paper K R MICRO NOTES 10

12. Extruded nets & Rachel bags Nets will be used to pack – Onions – Potatoes – Garlic & Ginger – Hard fruits like Ber Rachel Bags will help Retail Businesses to pack 25- 50 Kg produce at farms. Leno /Raschel /Net bags good aeration and strength. They have colourful look and are available in different sizes. These bags are recyclable and reusable. K R MICRO NOTES 12

13. Plastic Bags Plastic Bags- Plastic bags (polyethylene film) are the predominant material for fruit and vegetable consumer packaging. Besides the very low material costs, also reduce packing costs . Film bags are clear , allowing for easy inspection of the contents , and readily accept high quality graphics. • 13 K R MICRO NOTES 13

14. Shrink Wrap Shrink Wrap - potatoes, sweet potatoes, apples, onions, sweet corn. Shrink wrapping with an engineered plastic wrap can reduce shrinkage, protect the produce from disease, reduce mechanical damage and provide a good surface for stick-on labels. 14 K R MICRO NOTES 14

16. Rigid Plastic Packages Rigid Plastic Packages. packages with a top and bottom that are heat formed from one or two pieces of plastic are known as clamshells . Clamshells are most often used with consumer packs of high value produce items like small fruit , berries , mushrooms , etc., 16 K R MICRO NOTES 16

17. Plastic Punnets with lids Punnets are clean bright containers which offer product visibility. Holes provide ventilation and circulation of air thereby retaining the freshness of the produce. The containers are light weight, stackable and recyclable. K R MICRO NOTES 17

22. Epoxy coated Trays : These trays are clean, neat in appearance and light in weight . They give a cushioning effect to the products packed inside. The trays can be easily moulded in any size and shape The materials used can be easily cleaned, re-used and is also recyclable. K R MICRO NOTES 22

23. Polymeric Films K R MICRO NOTES 23

27. 2.Transport packaging Sacks Wood Pla s tics CFB K R MICRO NOTES 27

28. S a c k s Sacks are traditionally made of jute fibre or similar natural materials. For one tonne transportation of vegetables, materials of 250 grams per square meter or less are used. Sacks made of polypropylene of type plain weave are extensively used for root vegetables. K R MICRO NOTES 28

29. Wooden wire-Bound Crates Wire-Bound Crates - wooden wire-bound crates are used for commodities that require hydro cooling . Wire-bound crates are sturdy , rigid and have very high stacking strength 29 K R MICRO NOTES 29

30. Wooden Crates and Lugs Wooden crates- once extensively used for apples , stone fruit , and potatoes have been almost totally replaced by other types of containers. 30 K R MICRO NOTES 30

32. Corrugated fibre board boxes Corregulated Fibre Board are made from Bamboo, grasses and various types of agricultural residues as well as by recycling . Advantages of CFB Boxes: 1. They are light in weight. They cause much less damage. They are easy to handle and print. They improve the product image. They reduce the freight cost. K R MICRO NOTES 32

33. Pulp Containers Pulp Containers - made from recycled paper pulp and a starch binder. . Pulp containers are available in a large variety of shapes and sizes and are relatively inexpensive in standard sizes. can absorb surface moisture from the product, are also biodegradable, 33 K R MICRO NOTES 33

36. Intelligent Packaging “ Packaging that contains an external or internal indicator to provide information about aspects of the history of the package and/or the quality of the food”. Communicates information to the consumer based on its ability to sense, detect, or record external or internal changes in the product's environment. K R MICRO NOTES 36

37. Quality Indicators Quality or freshness indicators – indicates the quality of the product have become unacceptable the spoilage or lack or freshness of the product, Temperature Abuse Packet leakage Based on the reaction with volatile metabolites produced during ageing of foods and gives a visible colour change as an indicator of : CO 2 Amines Ammonia H 2 S K R MICRO NOTES 37

40. How RipeSense works There is a good correlation between the amount of aroma that is produced and the actual softening of the fruit. So as the fruit softens , it produces more aroma and sensor changes colour . K R MICRO NOTES 40

45. Conclusi o n Packaging of processed fruits and vegetables is an essential part of processing - ensures the safety and maintains value of food. Processing of fruits and vegetables without packaging has no meaning. Hence ,choose appropriate packaging system thereby to reduce the losses . K R MICRO NOTES 45
