Most countries, polyethene terephthalate, commonly known as PET, is used for manufacturing of polyester fibers, resins, bottles and engineering polyester resins.
Pet materials are highly resistant to crushing because they are not reactive to water, food and chemicals and are highly resistant to crushing.
Combination of these features, included low price has been made pet products an unquestionable choice in the food, beverage and industrial packaging .In Iran , PET has become widely used.
Pet bottling processing involve two stages:
In the first step, PET is made into a bottle (smaller than the size of the final bottle) by the injection molding machine and then the filaments of the bottle door are created. The resulting product is called PREFORM.
It is heated again to be stretched , which ultimately results in the formation of the final pet bottle.
This is in fact the same thing done with a PET Blowing Machine and eventually the final bottle shape is created by this machine.
Due to the nature of the pet’s moisture content, it must be moisturized by pre-injection equipment. Pet shrinkage and shrinkage during the injection process is very low and less than a fraction of one percent depending on the injection pressure, melting temperature, mold thickness, mold temperature and additive variations.
You can see the chemical and physical analysis attachments of consumables including Pet Grade 821 and 781.
