  5. 5. Multi Layer PET Bottles The multi layer bottles are made from PET / N-MXD6. A typical bottle will have 5 layers namely PET / N-MXD6 / PET / N-MXD6 / PET. It has excellent CO2 and O2 retention in the bottle as compared to the ordinary PET bottle. Also the multi layer gives greater strength and rigidity to the bottle.

  9. 9. Paper Container (Renjicco) This is a versatile paper based plastic laminated normally of PET. It can withstand freezing temperature on one hand and oven temperature on the other hand. Being microwavable and ovenable, it provides convenience and can be used as a serving container as well. The container is also environmental friendly.

  13. 13. Spouted Pouch There is an increasing trend in the use of pouch with spout. Compared with plastic bottles, the amount of plastics in pouch is much lower and therefore more environmental friendly. With the spout in place, it is reclosable as in plastic bottle. However, it has disadvantages such as slower filling speed and difficult to display on shelves.

  15. 15. Trends in Functional Packaging Materials • Light Barrier Film (U-SAVE) • Non-heating Packaging Materials for Microwave Oven • Moisture Absorbing Material • Self Heating / Cooling Containers • Biodegradable Plastics (Bionolle)
  16. 16. TRENDS IN FUNCTIONAL PACKAGING MATERIALS Light Barrier Film (U-SAVE) U-SAVE is a plastic sheet composed of several plastic films laminated by special adhesive which can shade more than 95% of ultraviolet rays while it transmits more than 80% of visible light. It has been developed as an ideal packaging material which meets the requirement to show the contents while shading ultraviolet rays.
  17. 17. TRENDS IN FUNCTIONAL PACKAGING MATERIALS Non-heating Packaging Materials for Microwave Oven The non-heating Packaging Materials for Microwave Oven is a new package for microwave oven that prevents heating using aluminium foil and thus able to prevent spark from occurring. This can be achieved by special design in such a way that no aluminium foil exists at edges.
  18. 18. TRENDS IN FUNCTIONAL PACKAGING MATERIALS Moisture Absorbing Material The material consists of highly water absorbent resins sandwiched between plastic film and paper. It is capable of absorbing and retaining moisture several hundred times its own weight. It serves as powerful absorber and water retainer, while allowing the retained moisture to disperse as water vapour. One such example is the ‘Total-Dry’ which is a barrier packaging material which has moisture absorbing function by having drying agent to the internal layers of laminated films. It prevents deterioration of moisture and maintains stable long- term quality contents.
  19. 19. TRENDS IN FUNCTIONAL PACKAGING MATERIALS Self Heating / Cooling Containers With consumers preference to have their drinks either warm or cold, the self heating or cooling containers were developed. Essentially such container will have a separate compartment in the container consisting of two chemicals separated from each other which upon mixing will give either exothermic or endothermic reactions. The reaction can be activated by having a simple mechanism such as a plastic needle to pierce through a layer separating the chemicals. A typical example is having CaO to react with water which gives out heat in the reaction.
  20. 20. TRENDS IN FUNCTIONAL PACKAGING MATERIALS Biodegradable Plastics (Bionolle) More and more biodegradable plastics are being researched and developed. One such example is Bionolle which is a biodegradable aliphatic polyester. Like wood and paper, Bionolle is stable in the atmosphere but biodegrades in compost, moist soil, water with activated sludge and in sea where a large number of microorganisms is present. It can be incinerated with less problem to the furnace as its combustion heat is relatively low and does not generate toxic or acid gases.
  21. 21. TRENDS IN RESEARCH ACTIVITIES •Oxygen Scavenging •Ethylene Scavenging •Antimicrobial Films •Sulphur Dioxide Emitting Films •Freshness Indicators •Improving Food by Food-Film Interaction
  22. 22. TRENDS IN RESEARCH ACTIVITIES Oxygen Scavenging Use of oxygen-scavenging technology can lower oxygen levels further, or can be used to permit the use of a cheaper packaging film. Oxygen-scavenging chemistry can be incorporated into films, adhesives, printing inks or lid seals, and so can be adapted to almost any type of package.
  23. 23. TRENDS IN RESEARCH ACTIVITIES Ethylene Scavenging The ripening and ageing processes of many fruits and vegetables are stimulated by ethylene. Removal of ethylene is an attractive way of extending the storage life. By incorporating the ethylene scavenging system into the packaging film (rather than adding a sachet to the package) the removal of ethylene is enhanced by the large surface area of the film.
  24. 24. TRENDS IN RESEARCH ACTIVITIES Antimicrobial Films Antimicrobial agents can be incorporated into a packaging film rather than in the food itself. The film can be configured to allow controlled release thereby extending shelf life. Films, both edible and inedible, based on biopolymers are being investigated.
  25. 25. TRENDS IN RESEARCH ACTIVITIES Freshness Indicators Since many foods lose their `freshness’ by oxidative reactions, films that change colour in response to the level of oxygen within a package can be used to indicate freshness.
  26. 26. Some Examples of Current Researches
  28. 28. THE IDEA The term ‘active packaging’ preserves the condition of the packed food to extend shelf life, to improve safety or sensory properties. Whilst a ‘smart packaging’ system monitors the condition of packed foods to give information about the quality of the packed food during transport and storage. An active-smart packaging using a bio-switch concept is a combination technology of biodegradable polymer, antimicrobial control releaser and pH-colour indicator from Anthocyanidin extracts. It is developed to detect (I) the degree of continuous natural fermentation in food products or (2) the spoilage of non-fermented food by microorganisms/chemical reaction by pH changes.
  29. 29. THE PRODUCT i.The Plastic Film – biodegradable from starch based formulation ii.Encapsulated colourant – natural, from plant extract iii.Antimicrobial Substances – varies e.g. essential oils, lysozyme, nisin and lauric acid Inhibition of E. coli by the antimicrobial film in liquid culture medium at 37 oC
  30. 30. THE PRODUCT iii. Anthocyanidin Group  controls the colour of the pigment  one of the things that change the color is the level of acid or alkali  the molecules are affected by the pH of the environment  antioxidant component neutralizes free radicals
  31. 31. THE PRODUCT Antimicrobial effects In blow molded plastic sheets In thermoformed plastic of film With AMI+® On-cap label film As container layer Use for dipping or coating
  32. 32. THE MECHANISM  This system consists of two main mechanisms: i. The first mechanism is the bioactive substances (antimicrobial) protect the food from external microbial contamination. ii. The second mechanism is the colour changes of the developed indicator represented properly the quality of the internal packed food and sustainability of the bioactive substances.

  37. 37. RESEARCH CONCLUSIONS **Microwave baking without packaging application had some quality defects such as lack of desirable, colour, become soggy, shrinked and brittle when cold. **When susceptor was used, ΔE values increased, showing that the colour of puffs were getting brown and darker, more than the control colour. Besides, it formed a texture similar to the conventionally baked ones at three level of power used. **In this study, the best conditions for baking puffs in microwave oven using susceptor packaging were 270s, 285s and 300s at 340W; 165s and 180s at 500W; and 105s and 120s at 790W. When susceptor packaging was applied for this condition, it reduced conventional baking time to about 75%-91%.

  45. 45. METHODS The cellulose processing was carried out according to Standard Test Method, ASTM No.D1103-60. Biocomposite formulation was processed for HDPE with 0, 30, 40 and 50% of cellulose and 0, 5 and 7% of PEG as plasticizer. In order to make each HDPE/Cellulose/PEG sample sheet, predetermined amount of materials were mixed using Thermo Haake PolyDrive R600/610 blending machine. Blending was carried out at 145 oC with rotor speed 30 rpm in 12 minutes. Then, composites obtained from melt blending were compressed using the Hot Press Machine for preparation of composite sheets with thickness of 1 and 3 mm.
