Abstract

A standardised and easy-to-apply method for general chemical inertness testing of refillable PET bottles was developed. It is applicable not only for the industry but also suitable for enforcement laboratories having for the first time a systematic control possibility to check the food safety of refilled PET bottles taken from the market. This chemical inertness test covers the sum of possible mechanical stress influences on the inertness behaviour of a PET material and, in case of complaint, allows the conclusion to the enforcement authority that something in the bottle manufacture process or in the wash/refill system went wrong or the recycle number might be too high.

In addition, a food grade reference PET material was prepared which fulfils the principle requirement of article 2 of the Framework Directive 89/109/EEC (1). This reference material was certified with respect to its interactivity values as shown below. Certified values were accompanied by an expanded uncertainty according to the requirements laid down in the Guide for the Expression of Uncertainty in Measurement (GUM) (2).
