IS : 10148 - 1982

Indian Standard POSITIVE LIST OF

CONSTITUENTS OF POLYVINYL CHLORIDE (PVC) AND ITS COPOLYMERS IN CONTACT

WITH FOODSTUFFS, PHARMACEUTICALS AND DRINKING WATER

0. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institution on 13 May 1982, after the draft finalized by the Plastics Sectional Committee had been approved by the Petroleum, Coal and Related Products Division Council.

0.2 Plastics are now being used on a large scale for packaging of foodstuffs and pharmaceuticals. Where direct contact occurs between the packed commodity and the plastics, the high-molecular-mass polymer itself does not pose a toxic hazard being inert and essentially insoluble in food. There is, however, a likelihood that some transfer will occur of polymer additives, adventitious impurities, such as monomers, catalyst remnants and residual polymerisation solvents and of low molecular mass polymer fractions from the plastics into the packaged material with consequent toxic hazard to the consumers. The occurrence of acute toxicity due to plastics materials in contact with food is most unlikely, since only trace quantities of potentially toxic materials are likely to migrate. However, the accumulation of these toxic materials with time may lead to hazards which may be serious.

0.3 Initially the Sectional Committee responsible for the preparation of this standard had prepared three codes of practice for safe use of polyvinyl chloride ( IS: 728%1974* ), polyethylene ( IS : 7277-19741) and styrene polymers (IS : 7961-1976:) in contact with foodstuffs, pharmaceuticals and drinking-water. Taking cognizance of the pressing need to monitor the quality of plastics intended to come in contact with foodstuffs, pharmaceuticals and drinking water which could not be done on the basis of standard codes of practice, the Committee decided to

*Code of practice for safe use of polyvinyl chloride (PVC) and its copolymers in contact with foodstuffs, pharmaceuticals and drinking water.

*Code of practice for safe use of polyethylene in contact with foodstuffs, pharmaceu- tical ‘and drinking water.

SCode of practice for safe use of styrene polymers in contact with foodstuffs, pharmaceuticals and drinking water.

3 L

IS:10148- 1982

prepare the following series of Indian Standards dealing with various aspects of plastics for food contact applications:

IS : 9833-I$81 List of pigments and colourants for use in plasticsin contact with foodstuffs, pharmaceuticaIs and drinking water;

IS : 9845-1981 Method of analysis for the determination of specific and/or overall migration of constituents of plastics materials and articles intended to come into contact with foodstuffs;

IS : 10 I4 l-l 982 Positive list of constituents of polyethylene in contact with foodstuffs, pharmaceuticals and drinking water;

IS : 10142-1982 Specification for styrene polymers for its safe use in contact with foodstuffs, pharmaceuticals and drinking water;

IS: 10146-1982 Specification for polyethylene for its safe use in contact with foodstuffs, pharmaceuticals and drinking water;

IS: 10148-1982 Positive list of constituents of polyvinyl chloride (PVC) and its copolymers in contact with food- stuffs, pharmaceuticals and drinking water;

IS : 10149-1982 Positive list of constituents of styrene polymers in contact with foodstuffs, pharmaceuticals and drinking water;

IS : 10151-1982 Specificattin for polyvinyl chloride ( PVC ) and its copolymers, for its safe use in contact with food- stuffs pharmaceuticals and drinking water; and

IS : 10171-198’2 Guide on suitability of plastics for food packaging.

Eventually the three codes of practice would be withdrawn with the publication of the product specification along with the corresponding positive list for the three plastics. Standards for other plastics for food contact applications like polypropylene and unsaturated polyester resins svhich are under preparation are expected to follow the same pattern, lamely, a product specification with a corresponding positive list. It is loped that this set of Indian Standards for plastics considered safe for hod contact applications would help the statutory bodies to effectively nonitor the quality of plastics for this end use.

Is : 10148 - 1982

0.4 The list of additives prescribed in these positive lists are based on the information available through published literature like British Plastics Federation Reports, London ( English); FDA Regulations, USA; and other national legislation reports.

1. SCOPE

1.1 This standard covers positive list of constituents of PVC, namely, the polymers, copolymers, manufacturing residues and necessary additives which may be regarded as safe for use, when properly processed in contact with foodstuffs, phamaceuticals and drinking water and when present in the prescribed limits of concentration.

1.2 The positive list does not purport to establish the suitability of the, ingredient singly in a particular foodstuff from other than toxicological considerations.
