IS 15392:2003 is the Bureau of Indian Standards specification for aluminium and aluminium alloy bare foil used in food packaging applications — covering the chemical composition, dimensional, mechanical, surface quality, and food safety requirements that aluminium foil must satisfy to be lawfully manufactured and supplied for food contact use in India.
BIS certification under IS 15392:2003 is mandatory for aluminium foil manufacturers supplying the food packaging market. Food processors, pharmaceutical manufacturers, dairy producers, confectionery companies, and FMCG packagers specify BIS-certified IS 15392:2003 aluminium foil as a standard procurement requirement — and regulatory compliance for food-contact packaging materials in India directly references BIS certification.
Key requirements under IS 15392:2003 include:
Chemical Composition
Defined alloy composition limits for aluminium and aluminium alloy foil — specifying maximum permissible levels of alloying elements and impurities. The chemical composition of the foil directly determines its corrosion resistance, mechanical properties, formability, and food safety performance. IS 15392 defines composition limits for each alloy designation covered under the standard.
Thickness and Dimensional Tolerances
Specified nominal thickness ranges and dimensional tolerances for the finished foil — ensuring consistent foil thickness that delivers predictable barrier performance, mechanical integrity, and converting behaviour on food packaging lines. Thickness variation outside defined tolerances compromises both packaging line performance and barrier consistency in the finished package.
Mechanical Properties
Tensile strength and elongation requirements for the aluminium foil — ensuring adequate mechanical performance for handling, converting, and end-use packaging applications. Foil that tears prematurely during packaging operations or in consumer use fails to protect the food product it is specified for.
Surface Quality
Defined limits on surface defects — including pinholes, cracks, scratches, roll marks, and inclusions — that affect both the barrier performance and food safety of the foil. Pinholes in food packaging foil allow oxygen and moisture ingress that reduces food shelf life and enables microbial contamination.
Pinhole Count
Maximum pinhole count per unit area — a critical food packaging performance parameter. Pinholes are inherent in thin aluminium foil but must be controlled within defined limits to ensure adequate barrier performance for the food packaging application. IS 15392 specifies maximum pinhole counts for each thickness range.
Corrosion Resistance
Resistance to corrosion under defined test conditions — ensuring the foil maintains integrity and does not generate corrosion products during contact with food, particularly acidic food products.
Freedom from Harmful Substances
Requirements ensuring the foil surface is free from lubricants, rolling oils, and chemical residues above defined limits that could migrate into food during packaging and storage.
Marking Requirements
Alloy designation, temper, nominal thickness, width, length or mass of coil, manufacturer identification, IS 15392 reference, and ISI Mark must be clearly and permanently marked on every certified consignment.
