In recent years, PET (polyethylene terephthalate) is the preferred packaging material for water and soft drinks. Plastic bottles are increasingly used for beer, juices, sports drinks and flavored spirits. But each product requires special qualities in its bottles. PET continues to gain popularity as an effective packaging material for beverage applications. Compared to other materials such as glass and metal, it is robust and light, easily recyclable. PET material also offers packaging designers and brand managers a high degree of design flexibility that allows them to differentiate their products. When low-cost production capacity is added to the equation, we can fully understand why there has been a steady increase in the production of PET containers worldwide.
