      Why choose PET over Glass?

      The debate regarding what type of material is best used for bottling has been on for a while now. Even though glass has its own benefits, PET seems to be taking more and more market share lately for a number of reasons.

      PET advantages over Glass:

      • Recyclability. PET is 100% recyclable and is considered the most environmentally friendly type of plastic;
      • Transportation costs. PET is 80% lighter than glass and therefore helps cut transportation cost due tojload weight;
      • Environmental contribution. Smaller fuel consumption during transportation means smaller CO2 emissions;
      • Weight. PET is not only more convenient to transport, but also to handle and store.
      • Durability. PET containers are reliable and have high impact resistance – bottles do not break when dropped.
      • Safety. Due to resistance to impact PET is shatter proof and guarantees completely shard free product.
