They are produced by HYTEX using a highly-accurate injection molding process on equipment from the leading world vendors. Preform weight depends on the end container’s desired volume. Preforms can be single-layer or multilayer. Barrier preforms provide additional benefits and increased beverage shelf life, thanks to a special layer embedded in several layers of polyethylene terephthalate.HYTEX offers a full assortment of polyethylene terephthalate (PET) preforms for packaging, transporting and storing drinking water, mineral water, carbonated beverages, juices, etc. To choose the best packaging option for your needs, contact a sales representative or technical support specialist.
