Types of liquid packages

• Glass Bottles : One of the conventional method of liquid packaging is glass bottles. This is used for packaging wine, liquor etc. The basic drawback of glass bottles is that they are fragile have more chances of breakage.
  
  
• PET Bottles : PET bottles have made inroads into the market for packaging edible oils, soft drinks, water & alcoholic drink sectors. In case of PET bottles, the drawback is that they do a poor job in keeping oxygen from permeating the container and reacting with the fill, which in turn can affect the fragrance, flavor & color of the drink.
  
  
• Aluminum Containers : One of the most popular liquid packaging method. Usually in the form of cans, they are used to store beer, aerated drinks etc.
  
  
• Paperboard Containers : They are widely recommended and have replaced glass bottles specially in flavored milk, fruit juices & drinks. Flexible packaging has nowadays taken over the fresh milk segment. Tetra packaging is very popular.
  
  
• Flexible Pouches : Today with innovation taking place from time to time , glass, paper containers and PET bottles have been replaced by flexible pouches in most of the applications. Superior graphics on the packets enhance product visibility and image. Most packs have easy opening and sealing options with zips. Moreover, such packaging has lesser breakages in transit. Stand up pouches have replaced the typical bag-in-box application. They are becoming an established package type because they can be easily placed on shelf in a vertical position so that they are visible to every customers.
