Food Packaging materials and their characteristics

  1. 1. COLLEGE OF AGRICULTURAL ENGINEERING AND TECHNOLOGY Food Packaging Technology (PFE-405) ASSIGNMENT: Food Packaging materials and their characteristics SUBMITTED BY: Arshpreet Kaur L-2017-AE-10-BIV B-TECH 4TH YEAR
  2. 2. PRODUCT PACKAGING MATERIAL CHARACTERISTICS PAPER : Kraft paper  Brown, unbleachedpaper.  Good strengthandresistant to Bursting  Economical  Environmental-friendly  Moisture-proof, water-proof, anti-oil Immersion  Easy to handle  Recyclable  Provides protectionagainst physical Damage  Holds the contents and keeps them Secure till used PAPER: Grease-proof paper  High-density paper,  Very smooth surface  Has air permeability allowing the food to breathe ,thus preventing a rapid loss of flavor and visual appeal  Impermeable tooil or grease  Machine friendly for printing  Highstrengthand stability  Can be usedin ovenand freezer  Easy to handle  Holds the contents and keeps them Secure till used  Cost-effective  Eco-friendly PAPER- BOARD  Highthickness  Suitable for printing  Highstrength  Light-weight  Higher weight per unit area  Can be easily cut and molded  Resists impact, abrasionand Compressiondamage  Made from multiple layers  Larger corrugation provides Cushioning
  3. 3. GLASS PACKAGING  They are impervious tomoisture Gases, odors, and microorganisms.  They are inert and do not react withor migrate intofood products.  They are suitable for heat processing When sealed.  They are transparent tomicrowaves.  They are reusable and recyclable.  They are resealable  They are transparent and display  The contents.  They can be moldedinto a variety of shapes and colors. Metal container packaging  They have a high strengthto weight ratio.  They can be heat processed.  They have excellent barrier and protective properties.  They produce shelf-stable productsth at ambient temperature.  They are tamperproof.  When sealedwitha double-seam they provide total protectionof the contents,  Ease of fabrication. ALUMINIUM FOIL PACKAGING  Good appearance  Excellent dead-folding properties  Ability toreflect radiant energy  Excellent barrier tomoisture, gases, and odors  Nonabsorbent andnontoxic  Highlevel of corrosionresistance  Guarantees longer shelf life  Light-weight  Low transport costs  100% recyclable  Flexible, i.e. Canbe moulded into Infinite number of shapes
  4. 4. PLASTIC: POLYESTERS (Polyethylene Terephthalate) PET BOTTLE  Good barrier togases like O2 and Co2  Longer shelf life  Good resistance toheat,mineral oils, solvents, andacids  Retentionof carbonation  Light weight  Absorbs very littlewater  Hard, stiff and dimensionally stable  Easy to transport  Recyclable and transport tomicrowave Radiation  Broad range of use temperature from -60 C to 130 C PLASTIC: Polyolefins Polypropylene  Harder, denser  Translucent  Good resistance tochemicals  Effective at barring water vapour  Highmelting temp. makes it suitable for applications where thermal resistance is required  Good fatigue resistance  Highly resistance tochemical corrosion  Resistant tomould, bacteria  Waterproof  Highinsulationproperties sousedin Electrical goods and cables PLASTIC: POLYSTYRENE  Clear, hard and brittle  Low melting point  Keeps food freshlonger  Excellent thermal insulation  Lightweight  Easy to handle  Colorless polymer usedfor lowcost Applications  Can be moulded or foamed to form A range of products  Provides protective barriertophysical  Damage
  5. 5. PLASTIC: LOW DENSITY POLYETHYLENE (LDPE)  Transparent inthin filmforum  Very low water absorption  Excellent coldresistance upto -70 C and so is used infrozenfood package  Good resistance toalcohols, alkalis  And acids  Susceptible tostress cracking  Low cost polymer  Excellent electrical insulating property  Moisture resistance  Highly flammable ---------------------------THANK YOU---------------------
