49. Sir R. Thompson

asked the Secretary of State for the Environment if he will make a statement on the progress of the research being carried on by his Department into the controlled instability of plastic packaging materials.

Mr. Eldon Griffiths

My Department is not itself engaged in practical research in this field, but details of work done elsewhere have been made available to the Plastics Institute Working Party on which it is represented.
