Glass Packaging

  1. 2. <ul><li>Glass is the only packaging material rated “GRAS” by the U.S. Food & Drug Administration. </li></ul><ul><li>maintains the purity of food and beverages </li></ul><ul><li>preserves a product’s taste or flavor </li></ul><ul><li>- No other packaging material matches the shelf impact of glass. </li></ul><ul><li>maintains the integrity or healthiness of foods and beverages </li></ul><ul><li>Glass is 100% recyclable and can be recycled endlessly with no loss in quality or purity. </li></ul><ul><li>-Recycling glass reduces consumption of raw materials, extends the life of plant equipment, such as furnaces, and saves energy </li></ul><ul><li>FOR FOODS </li></ul><ul><li>container of choice for processing high moisture foods </li></ul><ul><li>withstands exposure to acid food for an extended period of time </li></ul><ul><li>For Pasteurized foods- glass withstands the temperature and provides needed protection </li></ul>
  2. 3. <ul><li>-analyzing each new shipment of raw materials </li></ul><ul><li>-monitor certain easily measured physical properties of the glass </li></ul><ul><li>Eg. a.Density b.Softening Point </li></ul>
  3. 5. <ul><ul><li>Silica </li></ul></ul><ul><ul><li>An Alkali Network Stabilizers </li></ul></ul><ul><ul><li>-soda (Na 2 O) </li></ul></ul><ul><ul><li>or Potash (finer glass) </li></ul></ul><ul><ul><li>Limestone </li></ul></ul><ul><ul><li>Cullet (waste glass) </li></ul></ul>Na 2 O - CaO - Al 2 O 3 - SiO 2 Glass
  4. 6. Glass Added Substance-Oxides Use Example Lead -Brilliance -Weight Boron -Thermal & Electrical Resistance Barium Refractive Index Cerium Absorb IR
  5. 7. Glass Added Substance-Oxides Use Example Metallic Oxides Add color Manganese De-colorization
  6. 10. <ul><li>Because glass is chemically inert , it is the consumer's perfect protection for food and beverages. </li></ul><ul><li>Glass is one of the most sustainable packaging materials on earth, taking into consideration all carbon footprint factors . </li></ul><ul><li>Glass is true &quot;cradle-to-cradle&quot; packaging - meaning it can be recycled infinitely to be re-made into bottles, jars or containers that are equally pure as the original. The recycled product is so pure that it can again touch food or beverages. </li></ul><ul><li>Glass' impervious nature also makes it difficult to tamper with the package contents </li></ul><ul><li>protects delicate flavors and defend against oxidation </li></ul><ul><li>Increased visibility and shelf impact </li></ul><ul><li>Ability to act as decoration </li></ul><ul><li>Flexibility in size, shape, and closure </li></ul>
  7. 11. <ul><li>Marketers Rely on Glass Packaging to Deliver Consumer Convenience </li></ul><ul><li>Microwavable convenience (for many glass jars) </li></ul><ul><li>Ease in resealing </li></ul><ul><li>Flexible design </li></ul><ul><li>Extreme portability </li></ul><ul><li>Reusable </li></ul>
  8. 13. <ul><li>Lug or Twist Cap </li></ul><ul><ul><li>Lug is an inward protrusion from the curl of the cap side or skirt </li></ul></ul><ul><ul><li>Lug caps are secured to the finish by twisting the cap onto the finish which seats the lugs of the cap with the threads of the glass </li></ul></ul><ul><ul><li>Vacuum maintains the seal </li></ul></ul>
  9. 14. <ul><li>Plastisol-Lined Continuous Thread Cap </li></ul><ul><ul><li>This cap consists of a metal shell with a threaded skirt </li></ul></ul><ul><ul><li>Cap contains a flowed-in plastisol gasket and is applied by screwing the closure onto the glass finish </li></ul></ul>
  10. 15. <ul><li>Press On-Twist-Off Cap </li></ul><ul><ul><li>Gasket is molded Plastisol that covers the sealing area that extends from the top down the side </li></ul></ul>
  11. 16. <ul><li>Body of Glass Package: </li></ul><ul><ul><li>Largest portion of the glass container </li></ul></ul><ul><ul><li>Lies between the Finish and the Bottom of the package </li></ul></ul><ul><ul><li>Body can be in different shapes and sizes </li></ul></ul><ul><li>Bottom of Glass Package </li></ul><ul><ul><li>Bottom has the bearing surface or the portion of container upon which it rests </li></ul></ul><ul><ul><li>Bottom or bearing surface may have special configuration (Stacking feature) designed to provide a degree of interlocking </li></ul></ul>
  12. 17. <ul><li>Two properties of design: </li></ul><ul><li>Significance </li></ul><ul><li>Utility </li></ul><ul><li>Glass container manufacturing quality is a direct correlation to the process controls in place and to standards in which these controls are held: </li></ul><ul><li>Batching </li></ul><ul><li>Melting </li></ul><ul><li>Conditioning </li></ul><ul><li>Forming </li></ul><ul><li>Packaging </li></ul><ul><li>Warehouse </li></ul><ul><li>Shipping </li></ul>
  13. 18. <ul><li>Glass Enhancements </li></ul><ul><li>Applied Ceramic Labeling (ACL) or Silk Screening </li></ul><ul><li>Heat Transfer Labeling: </li></ul><ul><li>Shrink Sleeve </li></ul><ul><li>Pressure Sensitive Labeling </li></ul><ul><li>Cut and Stack Labeling </li></ul><ul><li>Glass Surface Treatments </li></ul><ul><li>Acid Etching Embossing </li></ul><ul><li>Specialty Colors </li></ul><ul><li>Debossing </li></ul><ul><li>Surface Treatment </li></ul><ul><li>At the hot end of the glass making process, a very thin coating of tin oxide is applied to the containers. </li></ul>
