The challenge of heat
Due to its chemical properties, PET changes its material properties (it contracts) as soon as it comes into contact with heat. This makes conventional PET (and therefore r-PET as well) unsuitable for products that are filled at temperatures above 60°C. The same applies to products whose packaging has to be sterilized at up to 100°C before filling, as is the case with many dairy applications.
The advantages at a glance:
r-PET HTS® can withstand temperatures of up to 100°C for a short period of time – in course of the filling or the sterilization process.
PET has good barrier properties and protects the product against external influences.
Depending on the application and customer requirements, PET HTS® packaging can be used in combination with recycled material.
"With PET HTS®, we can offer dairy customers a packaging solution for their products that uses recycled material without having to make any changes to their filling process.
