U.S. FDA Regulatory Compliance for Recycled Plastics in Food Packaging

In the United States, the use of recycled plastics in food packaging is permitted and overseen by the U.S. Food and Drug Administration (FDA). Specifically, the Office of Food Additive Safety (OFAS) under the FDA evaluates recycled plastic processes to ensure they do not introduce contaminants into food. While obtaining a No Objection Letter (NOL) is voluntary, it is highly recommended as a positive validation of a recycling process and is often a prerequisite for industry recognition and market access.

The primary regulatory framework includes:

• Federal Food, Drug, and Cosmetic Act (FD&C Act).
• Code of Federal Regulations (CFR) Title 21.
• Guidance for Industry: Use of Recycled Plastics in Food Packaging (Chemistry Considerations).

The No Objection Letter (NOL)

An NOL is a formal response from the FDA stating that the agency has no safety concerns regarding the use of a specific recycled plastic in food-contact applications.

Who May Apply for an NOL?

• Recycled plastics manufacturers.
• Recycled plastics equipment manufacturers.
• Recycled plastics users (jointly with the manufacturer).

If an equipment manufacturer obtains an NOL, downstream manufacturers using that certified equipment typically do not need a new NOL, provided the process and intended use remain identical to the original application.

Classification of Recycling Processes

The FDA recognizes three primary types of recycling processes, all of which are eligible for NOL applications:

Primary Recycling

Involves re-processing industrial scraps generated during the production of food-contact materials within a closed-loop system. These materials must comply with Good Manufacturing Practices (GMP).

Secondary Recycling

Also known as Physical Recycling, this process involves mechanical methods such as grinding, melting, and extrusion. The goal is to remove contaminants while keeping the polymer structure unchanged.

Tertiary Recycling

Also known as Chemical Recycling, this involves breaking down plastics into monomers or oligomers through chemical reactions, followed by purification and re-polymerization to create new plastic resins.

NOL Application Data Requirements

Data requirements vary based on the intended use of the recycled plastic:

Specific Intended Use

Applies to plastics used for specific food types (e.g., raw fruits, vegetables) under room temperature or refrigerated conditions. Required data includes process descriptions, intended use details, and compliance test reports.

General Intended Use

Applies to plastics used with all food types, including high-temperature sterilization. This requires a Challenge Test (Surrogate Contaminant Testing) to verify the decontamination efficiency of the recycling process.

Application Workflow

The general process involves:

1. Data Collection: Gathering all technical and manufacturing information.
2. Compliance Analysis: Comparing data against FDA safety standards.
3. Testing: Conducting surrogate contaminant or general compliance tests.
4. Dossier Submission: Preparing and submitting the technical file to the FDA.
5. Official Review: The FDA reviews the safety and technical data.
6. Issuance: Upon successful review, the FDA issues the NOL.
