What does PET plastic mean?
PET Plastic is a strong, clear, plastic commonly used for food packaging, plastic bottles, and household containers.
Its chemical name is polyethylene terephthalate. It is identified by the number 1 encircled by the recycle symbol.

PET plastic bottles are the most widely used beverage packaging today.
It is not only widely used in the packaging of carbonated beverages, drinking water, fruit juice and tea beverages, but also in food, cosmetics, medicine, chemical packaging and many other fields.

PET plastic  bottle properties and advantages:

  • Non-toxic and tasteless, it can be directly used in food packaging.

  • Resistant to oil, fat, dilute acid, dilute alkali and most solvents.

  • High transparency, can block ultraviolet rays, good gloss.

  • Low gas and water vapour permeability and excellent barrier properties to gas, water, oil and odors.

  • Cheap price and low production cost.

  • Safe and not easily broken, causing danger.

  • Energy efficient, lightweight and easy to transport, requiring less fuel to transport.

  • Sustainable, recyclable and reusable.

  • Can be shaped into different shapes and sizes, enabling brands to use them to build identities and promote drinks.

Is PET really eco-friendly? What is its recycling process?
PET is Eco-friendly and can be recycled almost infinitely, and since it can be made into new products, this reduces the need for virgin PET manufacturing, further reducing emissions.

  • One type of method is to alcoholyze the PET plastic recycled material, then add dibasic acid anhydride and other polycondensation to a certain acid value.
    After dilution, filtration and adding an appropriate amount of catalyst, alkyd resin paint can be obtained, which has good adhesion, acid resistance and resistance.
    It has the characteristics of alkali and waterproof, and can be used as floor coating.

  • Another method is to granulate the recycled PET plastic bottles after washing, separating, drying.
    Containers, accessories, fibers, etc. can be used for the preparation of non-food products.
    Speaking of fibers, the world's annual consumption of PET materials used in the fiber industry at the end of the last century was about 11.4 million tons, accounting for 70% of the world's total PET production.
    The recycled PET material is finally spun into polyester yarn and woven into polyester fiber fabric after separation, cleaning, crushing, drying, plasticizing, plying, carding and other processes.
  • For example, this dress contains 88% polyester.

About PET  bottle manufacturing

Important factors affecting the blow molding process of PET bottles include preform, heating, pre-blowing, mold and production environment.
If the material is not good, the requirements for the process are very strict, and it is even difficult to blow a qualified bottle.

  • For the manufacture of the bottles we use only raw materials

  • Our blow molding machines for PET bottles

  • Our production environment
