## Introduction

When it comes to packaging food products, safety isn’t optional—it’s the law. Whether you’re a bakery owner wrapping fresh bread, a coffee roaster packaging beans, or a manufacturer producing snack foods, understanding food safe plastic bags and FDA compliance is critical to protecting your customers and your business.

In this comprehensive guide, we’ll explain everything you need to know about FDA regulations for food contact packaging, how to identify truly food-safe materials, and how to choose the right bags for your products.

What Makes a Plastic Bag “Food Safe”?

Not all plastic bags are created equal. A bag that’s perfectly fine for storing hardware or clothing could be dangerous when it comes in contact with food.

Food safe plastic bags must meet these criteria:

1. Made from FDA-Approved Resins

The U.S. Food and Drug Administration (FDA) maintains a list of approved materials for food contact under the Code of Federal Regulations (CFR) Title 21. Common food-safe plastics include:

  • Polyethylene (PE) – Used in most food bags, including poly mailers and produce bags
  • Polypropylene (PP) – Common in stand-up pouches and clear cello bags
  • Polyester (PET/PETE) – Used in some rigid and flexible packaging

2. Free from Harmful Additives

Even if a bag is made from approved resin, additives like colorants, stabilizers, or plasticizers must also be FDA-approved for food contact. Non-food-grade bags may contain:

  • Lead or cadmium (in some colored plastics)
  • Phthalates (plasticizers linked to health concerns)
  • Recycled materials of unknown origin

3. Manufactured Under Food Safety Standards

Food-safe bags should be produced in facilities that follow Good Manufacturing Practices (GMPs) to prevent contamination during production.

At NFC Bags, our food-safe packaging is manufactured in HACCP-certified facilities, ensuring the highest food safety standards.

FDA Regulations for Food Contact Packaging

The FDA regulates food packaging under 21 CFR Parts 170-199, which covers “food contact substances” (FCS). Here’s what you need to know:

Key FDA Requirements

1. Food Contact Notification (FCN) or GRAS Status
Manufacturers must prove that materials intended for food contact are safe through:

  • Generally Recognized as Safe (GRAS) status, or
  • An approved Food Contact Notification (FCN) submitted to the FDA

2. Migration Testing
Plastics must be tested to ensure harmful substances don’t migrate into food. Testing considers:

  • Type of food (aqueous, acidic, fatty, dry)
  • Storage temperature
  • Contact duration

3. Intended Use Declaration
Packaging must be labeled for its intended use. A bag approved for dry foods may not be safe for hot, fatty, or acidic foods.

Common Misconceptions

❌ “Virgin plastic is always food safe”
Not true. Virgin (non-recycled) plastic must still be made from FDA-approved resins and additives.

❌ “BPA-free means food safe”
BPA-free is just one aspect. Other chemicals and production processes matter too.

❌ “Food-grade is the same as food-safe”
“Food-grade” is a marketing term. Look for FDA-compliant or FDA-approved for food contact.

How to Verify Food Safety Compliance

Don’t just take a supplier’s word for it. Here’s how to verify food safety compliance:

1. Request a Certificate of Compliance (COC)

Reputable suppliers provide documentation proving their bags meet FDA regulations. This should include:

  • Resin composition (specific polymers used)
  • FDA regulation reference (e.g., 21 CFR 177.1520 for polyethylene)
  • Testing results for migration (if applicable)
  • Manufacturing facility certifications

2. Check for Third-Party Certifications

Look for certifications like:

  • HACCP – Hazard Analysis Critical Control Points
  • SQF – Safe Quality Food certification
  • BRC – British Retail Consortium (global food safety standard)

NFC Bags is HACCP certified, demonstrating our commitment to food safety at every stage of production.

3. Review Material Safety Data Sheets (MSDS)

An MSDS (now called SDS – Safety Data Sheet) lists all chemical components and their safety profiles.

4. Ask About Manufacturing Practices

Food-safe bags should be manufactured in:

  • Clean, controlled environments
  • Facilities separate from non-food-grade production
  • Operations with regular quality audits

Custom Printed Food Safe Bags: What You Need to Know

Want to add your branding to food-safe bags? Here’s what to consider:

1. Inks Must Be Food-Safe

Not all printing inks are approved for food contact. Look for:

  • Water-based inks (safest option)
  • UV-curable inks (approved for specific applications)
  • Solvent-based inks (must be fully cured and meet FDA regulations)

2. Printing Location Matters

  • Outside printing only: Safest, no direct food contact
  • Reverse printing (inside laminate): Ink is sandwiched between layers, no food contact
  • Direct food contact surface: Requires special low-migration inks

3. Migration Testing for Printed Bags

Custom printed bags intended for food contact should undergo migration testing to ensure:

  • Inks don’t transfer to food
  • No harmful substances leach during storage

Food Safety Beyond the Bag: Handling & Storage

Even FDA-compliant bags can become contaminated through improper handling. Follow these best practices:

Storage Best Practices

  • Store bags in a clean, dry environment
  • Keep away from chemicals, cleaning products, and non-food items
  • Use a first-in, first-out (FIFO) system to prevent deterioration
  • Protect from direct sunlight (can degrade plastics over time)

Handling Guidelines

  • Wash hands or wear food-safe gloves before handling bags
  • Don’t reuse bags that have contacted raw meat, seafood, or allergens
  • Inspect bags for tears, holes, or contamination before use
  • Follow temperature guidelines (some bags aren’t rated for hot foods)

Documentation & Traceability

Maintain records of:

  • Bag supplier and lot numbers
  • Certificates of compliance
  • Usage dates and products packaged

This documentation is critical if you’re audited for food safety compliance.

Frequently Asked Questions

Q: Are all poly bags food safe?

A: No. Only bags specifically manufactured from FDA-approved food-grade resins and produced in food-safe facilities are considered food safe.

Q: Can I use regular plastic bags for food if I wash them first?

A: No. Non-food-grade bags may contain additives or contaminants that can’t be removed by washing.

Q: How can I tell if a bag is food safe just by looking at it?

A: You can’t. Always request certification from your supplier. Food-safe and non-food-safe bags can look identical.

Q: Do I need different bags for hot vs. cold food?

A: Yes. High-temperature foods require bags rated for heat resistance. Standard LDPE bags may not be safe above 150°F (65°C).

Q: Are biodegradable bags food safe?

A: Some are, some aren’t. Biodegradable bags made from FDA-approved materials (like certain PLA or PBAT formulations) can be food safe. Always verify certification.
