Bottling & packagings (PET, PP & PE)

Plastic bottles made out of PET are currently widely replacing heavy and fragile glass bottles as reusable packaging for mineral water and lemonades. PE and PP are also being used for producing non-reusable bottles and packagings.

They are produced in large quantities via the bottle-forming process. Preformed plastic blanks, or so-called preforms, pass infrared heat sources, which heat them to the required temperature for forming, in excess of the glass transition temperature. For PET, this temperature is approximately 110 °C.

PE and PP are turned into containers in similar processes. These polymers are difficult to heat by infrared radiation. Therefore, the use of the heating accelarators developed by Budenheim is very helpful when working with PE and PP. They provide for an economic and simple production process.
