  1. 1. OVERVIEW OF PLASTIC BOTTLES PREPARED BY KAVAR GAURAV DDU, NADIAD(GUJARAT)
  2. 2. INTRODUCTION  A plastic material is any of a wide range of synthetic or semi- synthetic organic solids that are moldable.  Plastics are typically organic polymers of high molecular mass but they often contain other substances.  They are usually synthetic, most commonly derived from petrochemicals , but many are partially natural.
  3. 3. Raw- materials  Most plastic water bottles are made from polyethylene terephthalate (PET).  Pet bottles are replacing glass bottles because of the high rate of breakage and the inconvenience of returning the empty bottle after consumption.  Polymer derived from oil that adds flexibility, color, and strength to plastic.  It is impermeable to carbonation. It is strong, light, impact resistant, naturally transparent, and completely recyclable.
  4. 4. Raw- materials  Some other raw -materials are polyethylene, High-density polyethylene(HDPE).  Some plastic bottles contain small amount of Bisphenol A (BPA).
  5. 5. Synthesis route (PET)  An “ester” is the reaction product of an organic acid and an organic base.  PET formed by reacting ethylene glycol (base) and terephthalic acid Condensation polymerization reaction  Largest use in injection blow molded
  6. 6. Manufacturing process & Technology  For making a plastic bottles Blow molding mostly use.  Blow molding is a manufacturing process by which hollow plastic bottles are formed.  In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding.
  7. 7. Manufacturing process & Technology  The blow molding process begins with melting down the plastic and forming. Blow molding is a manufacturing process by which hollow plastic parts(bottles) are formed.  A section of molten polymer tubing is extruded into an open mold.  By means of compressed air or steam the plastic is then blown into the configuration of the mold.
  8. 8. Manufacturing process & Technology  Injection blow molding is generally suitable for smaller containers and absolutely no handles ware.  Injection blow molding is often used for containers that have close tolerance threaded necks, wide mouth openings,and highly styled shapes.  The air is injected into the plastic at a rate between 75 to 150 PSI.
  9. 9. Manufacturing process & Technology  Injection molding can be broken down into three stages.  The first stage is where the melted plastic is injected into a split steel mold cavity from the screw extruder.  The mold produces a preform parison which resembles a test tube with a screw finish on the top.  The preform is then transferred on a core rod to the second part of the injection blow molding stage. The preform is then placed inside another cold and usually aluminum blow mold cavity.
  10. 10. Manufacturing process & Technology  Air is then injected through the core rod till the preform takes the shape of the cavity.  While still on the core rod, the container is then transferred to a desired location for the third stage, where it is ejected from the machine.
  11. 11. Manufacturing process & Technology
  12. 12. properties  plastic bottles can take a beating. Versatile and durable.  It can be recycle and reuse.  Easily disposable.  Thermoplastic in nature.
  13. 13. Various plastic bottles  Carbonated drinks bottles are made from Polyethylene terephthalate(PET).  Detergent bottles are made from High-density polyethylene(HDPE).  Bottle caps are made from Polypropylene(PP).  During process various types of ingrediants like Fillers Plasticizers, Colorants should be added.
  14. 14. Applications  packing of Edible oils  packing of jams and sauces  packing of Butter, syrups and Drinking water having capacity from 500ml to 2 lit.
  15. 15. Major applications  Carbonated soft drinks.  Mineral water packing.  Agro chemical packaging.  House hold containers.
  16. 16. Recycling process  This process divided into four stages.  1. plastic bottles puts into the appropriate recycling container or local recycling point.  2. The plastic is then taken to a sorting facility where it is baled and taken to a processing facility.  3. At the processing facility infra-red technology is used to sort the mixed bottles into their separate types  4. The bottles are then shredded into either plastic flakes (PET) or granules (HDPE)  5. Flakes and granules are then melted and processed with various techniques and returned to the manufacturers of plastic bottles.
