Packaging & Cosmetics



The irradiation of plastic packaging materials has a variety of business applications. It is possible to irradiate packaging materials after being filled, depending on the category of product packaged.Cosmetics and naturally derived products can be irradiated with great success, with minimal or no visible change to either product or packaging.

Sterilization and sanitization by e-beaming is a continuos method with short exposure time which does not require the product to be in quarantine after treatment. Due to the dosimetric system used, conventional post-sterilization testing is not required. It is possible for us to release product based on dosimetric results.

The material must be compatible with the e-beaming process. The table below indicates the tolerance levels and grades the stability of commonly used polymers.
