Food Contact Materials Safety Standards in India: BIS and FSSAI Guide

Every material that touches food -- the cup that holds your morning chai, the container carrying your lunch delivery, the aluminium foil wrapping your evening kebab -- is classified as a "food contact material" (FCM). These materials are governed by a specific set of safety standards designed to ensure that nothing harmful migrates from the packaging into the food. In India, these standards are defined by FSSAI and the Bureau of Indian Standards (BIS), and compliance is mandatory for manufacturers, suppliers, and end-users of food packaging.

This guide provides a detailed reference for food contact material safety standards in India, covering the regulatory framework, specific material standards, testing requirements, and practical compliance guidance for food businesses.

The Regulatory Framework for Food Contact Materials

India's food contact material regulations operate through a layered system:

Level 1: FSSAI (Primary Regulator)

The Food Safety and Standards (Packaging) Regulations, 2018, is the primary regulation governing food contact materials in India. This regulation:

• Defines which materials are approved for food contact use.
• Sets overall migration limits (the total quantity of substances that can transfer from packaging to food).
• Establishes specific migration limits for individual hazardous substances.
• Prohibits specific materials and substances from food contact use.
• Requires compliance certificates for all food contact packaging.

Level 2: BIS (Standards Body)

The Bureau of Indian Standards publishes the technical specifications that define "food grade" for each material type. FSSAI regulations reference these BIS standards. Key BIS standards for food contact materials:

BIS Standard	Material Covered	Key Parameters
IS 9845:1998	Plastics (PP, PE, PET, PS, etc.)	Overall migration limit 60 mg/kg; specific migration limits for individual substances; food simulant testing protocols
IS 6615	Food-grade paper and board	Lead content, antimony, arsenic limits; fluorescent whitening agent limits; recycled material restrictions
IS 15495	Aluminium foil for food packaging	Lead below 10 ppm; arsenic below 2 ppm; lacquer coating standards; pinhole limits
IS 2467	Glass containers	Lead and cadmium release limits; thermal shock resistance; dimensional standards
IS 4853	Ceramic ware for food contact	Lead release limits by vessel category; cadmium release limits
IS 14543	Drinking water bottles (PET)	Specific to bottled water packaging; migration limits for acetaldehyde and other PET-specific substances

Level 3: Testing Laboratories

NABL-accredited laboratories conduct the migration testing that verifies compliance with FSSAI and BIS standards. Manufacturers must get their products tested at approved labs and maintain valid test reports.

Understanding Migration: The Core Safety Concept

"Migration" is the transfer of substances from packaging material into food. It is the central concept in food contact material safety. All packaging materials release some substances into food -- the question is whether these substances are within safe limits.

Overall Migration Limit (OML)

The total quantity of all substances that migrate from packaging to food must not exceed 60 mg/kg of food (or equivalently, 10 mg/dm2 of packaging surface area). This is the primary compliance threshold for all food contact materials in India.

Specific Migration Limits (SML)

Individual hazardous substances have their own maximum migration limits, which apply in addition to the OML:

Substance	Maximum SML	Health Concern	Common Source
Lead	1 mg/kg	Neurological damage, kidney damage, developmental effects in children	Printing inks, PVC stabilisers, ceramic glazes, recycled materials
Bisphenol A (BPA)	0.6 mg/kg	Endocrine disruption, reproductive effects	Polycarbonate plastics, epoxy can linings
Cadmium	0.002 mg/kg	Kidney damage, bone disease	Ceramic glazes, coloured plastics, recycled materials
Phthalates (DEHP)	1.5 mg/kg	Endocrine disruption, liver effects	Plasticisers in PVC, cling films, flexible plastics
Formaldehyde	15 mg/kg	Irritant, potential carcinogen	Melamine-formaldehyde plastics, some adhesives
Melamine	2.5 mg/kg	Kidney damage	Melamine tableware, some adhesives
Aluminium	No specific SML (general food safety limits apply)	Neurological concerns at high exposure	Aluminium foil and containers, especially with acidic foods

Factors That Increase Migration

Migration is not a fixed value -- it increases under certain conditions:

• Temperature: Higher temperatures accelerate chemical migration. This is why temperature-material compatibility is so important. A PP container at 25 degrees C might release 5 mg/kg, but at 100 degrees C it might release 40 mg/kg.
• Contact time: Longer contact between food and packaging increases migration. Short-term food service (eat within 1-2 hours) has lower migration risk than long-term storage (days or weeks).
• Food composition: Fatty and acidic foods extract more substances from packaging than dry, neutral foods. This is why migration testing uses different food simulants for different food categories.
• Surface area ratio: Small containers with large surface-to-volume ratios (like paper cups for tea) have higher migration per kilogram of food than large containers.

Material-by-Material Safety Guide

Plastics (PP, PE, PET, PS)

Plastics are the most regulated food contact material because they contain the widest variety of additives (plasticisers, stabilisers, colorants) that can potentially migrate. Key safety considerations:

• PP (Polypropylene): Generally considered the safest common food-contact plastic. Heat resistant to 120 degrees C. No BPA. Low migration rates. This is why PP is the material of choice for microwave-safe food containers and hot food packaging.
• PE (Polyethylene): Safe for cold and room-temperature food contact. Used as inner coating for paper cups. Avoid extended contact with hot fatty foods above 85 degrees C.
• PET (Polyethylene Terephthalate): Safe for cold beverages and room-temperature foods. Not suitable for hot foods above 70 degrees C. Primary concern is acetaldehyde migration in bottled water stored in hot conditions.
• PS (Polystyrene): Contains styrene monomer which is a potential carcinogen. Migration increases significantly above 80 degrees C. Expanded PS (thermocol) is banned under plastic waste rules. Standard PS is still used in some applications but is being phased out.

Paper and Board

Paper-based food contact materials (paper cups, paper plates, food wrapping paper) must comply with IS 6615. Safety considerations include:

• Virgin vs. recycled: Only virgin paper is approved for direct food contact. Recycled paper may contain residual printing inks (which contain heavy metals), mineral oils (MOSH/MOAH), and other contaminants.
• Coatings: PE or PLA coatings on paper cups and plates must themselves be food-grade. The coating is the actual food-contact surface.
• Printing: Printed surfaces must not contact food directly. Food-safe inks must be used, and the print must be on the exterior surface only.
• Fluorescent whitening agents: Regulated under IS 6615 because they indicate chemical treatment that may introduce contaminants.

Aluminium

Aluminium foil and containers are governed by IS 15495. While aluminium is generally safe for food contact, specific precautions apply:

• Acidic food interaction: Aluminium dissolves in acidic environments. Tomato-based curries, lime preparations, vinegar-based pickles, and curd dishes should not be stored in uncoated aluminium for extended periods.
• Lacquer coatings: Coated aluminium containers are safe for acidic foods. Verify that the lacquer coating is food-grade (some industrial coatings are not suitable for food contact).
• Heavy metal limits: Lead below 10 ppm, arsenic below 2 ppm as per IS 15495.

Natural Materials (Bagasse, Areca, Bamboo)

Eco-friendly materials have gained significant market share but must still meet food contact safety standards:

• Sugarcane bagasse: Generally safe when produced under controlled conditions. Ensure the manufacturing process does not introduce chemical contaminants. Coated bagasse products must use food-grade coatings.
• Areca leaf: Naturally formed and minimally processed. Low migration risk. Verify that no chemical treatments (bleaching, preservatives) have been applied.
• Bamboo: Can contain formaldehyde-based adhesives if laminated. Solid bamboo products are generally safe. Always request food-grade certification.

How to Verify Food Contact Material Compliance

For Packaging Users (Restaurants, Caterers, Food Businesses)

You are not expected to conduct migration testing yourself, but you are legally required to use only compliant packaging. Here is how to verify:

1. Request certificates: Ask your packaging supplier for food-grade certificates and migration test reports. A reputable supplier will provide these without hesitation.
2. Check BIS marks: Look for the ISI mark or BIS certification on packaging products or their outer cartons. This indicates the product has been tested against the relevant IS standard.
3. Verify test report validity: Migration test reports should be from NABL-accredited laboratories, dated within the last 2 years, and specific to the product you are purchasing (not a generic report).
4. Maintain records: Keep all compliance certificates and test reports on file. FSSAI inspectors can request these during audits.
5. Monitor product consistency: If the appearance, feel, or smell of packaging from your regular supplier suddenly changes, request updated compliance documentation -- the material composition may have changed.

For Packaging Manufacturers and Distributors

Manufacturers and distributors bear direct responsibility for product compliance:

• Conduct migration testing at NABL-accredited laboratories for every product formulation.
• Maintain BIS certification for products covered by mandatory BIS standards.
• Provide food-grade certificates and test reports to all customers.
• Implement batch traceability so that any compliance issue can be tracked to specific production batches.
• Re-test products whenever raw material sources, manufacturing processes, or product formulations change.

International Standards Comparison

For businesses that export food products or source packaging internationally, understanding how Indian standards compare with international frameworks is useful:

Parameter	India (FSSAI/BIS)	EU (EC 1935/2004)	USA (FDA 21 CFR)
Overall Migration Limit	60 mg/kg	10 mg/dm2 (approx. 60 mg/kg)	No single OML; substance-specific limits
BPA Limit	0.6 mg/kg	0.05 mg/kg (restricted since 2023)	No explicit limit (FDA considers current levels safe)
Lead Limit	1 mg/kg	Varies by material	Varies by material and use
Recycled Material	Restricted for direct food contact	Regulated under EC 282/2008	Regulated under FDA letters of no objection
Testing Approach	Food simulant-based migration testing	Food simulant-based with specific conditions	Extraction testing with solvents

Indian standards are broadly aligned with EU standards for overall migration limits. However, some specific substance limits (particularly BPA) are less stringent than the latest EU standards. FSSAI has indicated that further tightening of specific migration limits is expected in coming years.

Red Flags: When to Question Your Packaging Safety

Be alert to these warning signs that your food contact materials may not meet safety standards:

• Strong chemical odour: Food-grade packaging should be essentially odourless. A noticeable chemical smell indicates volatile substances that are likely migrating into food.
• Unusually low price: If packaging is priced significantly below market rate, material quality may have been compromised. Cheaper raw materials typically have higher contaminant levels.
• No documentation available: If your supplier cannot provide food-grade certificates or test reports, treat the product as non-compliant until proven otherwise.
• Colour bleeding: If printed packaging releases colour when rubbed or when in contact with moist food, the ink is not food-safe.
• Structural failure with hot food: If containers warp, soften, or deform when filled with hot food, the material is being used beyond its safe temperature range, increasing migration risk.
• Inconsistent quality: Variations in thickness, colour, or feel between batches suggest inconsistent raw material sourcing, which may include non-food-grade materials.

Food contact material safety is the invisible foundation of food packaging. Getting it wrong puts your customers' health at risk and exposes your business to significant legal liability. Getting it right -- through informed material selection, supplier verification, and proper documentation -- is straightforward and protects everyone in the food chain.
