Migration from packaging materials into foodstuffs--a need for more fundamental information

During recent years considerable legislative attention has been focused on food packaging materials, especially plastics, and in a number of countries extensive legislation has been formulated. Such legislation often takes the form of a positive list of permitted substances accompanied either by compositional limits or migration limits in foods or stimulant liquids. In the UK this approach has not been followed owing to the general lack of fundamental information on which to base such a system. Instead, the UK has opted for a basic legislative framework supported by informal controls which rely to a large extent on close co-operation between Industry and Government. It is recognized, however, that in future years there is likely to be a move towards more extensive legislation on packaging materials in the UK, particularly as a result of the EEC's harmonization programme. It is imperative that any future legislation is placed on a sound scientific footing and affords adequate protection for the consumer. The Government of the UK is, therefore, currently sponsoring a number of studies aimed at providing this necessary basic information.
