Advance technology in food processing and food packaging play a play major role in maintaining safe food supply to retailers and wholesalers. Glass materials used in food package enables foods to transport from their point of origin, in its original form, up to the time of consumption.
Glass material has a long history in food packaging. The process involves heating of glass and other materials to a very high temperature where these are melted to form a thick liquid mass which is poured into molds. Companies are also using broken glass (cullet) materials and it contains 60% of all raw materials. To eliminating scratching or surface abrasion and line jams, internally coated glass containers are available. This coating enhances the life of packaging material and reduces breakage. Improvement in break resistance allows manufacturers to use thinner glass. This reduce weight and easy to “dispose of” and also for transportation.
