Comprehensive Program for Food-Contact Material Produced from Recycled Fiber

Under authority of the Food, Drug and Cosmetics Act, the U.S. Food and Drug Administration (FDA) regulation (21CFR.176.260) use of pulp from reclaimed fiber is allowed for food packaging. This regulation recognizes that the sources of reclaimed fiber may be either "industrial waste from the manufacture of paper and paperboard" or "salvage from used paper and paperboard...." In both cases, the regulation stipulate that the material may not bear or contain "any poisonous or deleterious substance... that migrates to the food except as provided in the regulations...."

In 1999, the Recycled Paperboard Technical Association (RPTA) and the American Forest & Paper Association jointly published a document, Guidance for Industry on The Use of Pulp from Reclaimed Fiber as a Component of Paper and Paperboard Products for Food Packaging under 21 C.F.R. 176.260. The Guidance identified steps appropriate to ensure compliance with FDA requirements. To complement the Guidance, RPTA issued the first edition of its Chemical Testing Protocol for Food Contact Paperboard Made from Recycled Fiber (RPTA Protocol) as a tool to help manufacturers of recycled paper, paperboard and containerboard identify substances in recycled fiber packaging substrates and determine the regulatory status of those substances.

Since then, the RPTA Protocol has evolved into a comprehensive program to ensure that recycled paperboard and containerboard can be the first choice for food packaging.

The RPTA Comprehensive Program

In March 2022, RPTA rolled out its most recent update of the program to ensure manufacturers of recycled paperboard and containerboard used in food-contact applications can continue to assure compliance with FDA requirements. The Program has been enhanced to comprehensively address the various regulatory requirements under the FDA statutory authority that apply to recycled paperboard and containerboard use in food packaging. The Program includes processes to address:

  • Use of reclaimed fiber in paperboard intended for direct food contact as stipulated in 21 CFR 176.260
  • Control of sources of recovered fiber
  • Use of additives suitable for food contact as stipulated in 21 CFR176.170 and 21 CFR 176.180
  • Implementation of microbiological testing to assure that contamination of the surface of the paperboard or containerboard is reduced to as low as practicable and the recycled fiber packaging substrate is free of pathogens
  • Implementation of Good Manufacturing Practices which include a variety of processes to assure the manufacturing of the packaging does not render the package unfit for food
  • Implementation of a chemical testing protocol for quality control end-testing
  • Maintenance of adequate company records

RPTA Chemical Testing Protocol

From the beginning, RPTA developed the chemical testing protocol through the collaborative efforts of industry experts, outside consultants, and experts in the area of health-risk assessment. It addresses chemicals that are the subject of FDA regulations for food packaging and California's Proposition 65 with regard to unintentional chemical constituents.

The RPTA Protocol contains a list of chemicals developed in cooperation with leading food safety industry experts, along with their corresponding health risk-based allowable concentrations. The Protocol establishes a testing regime to evaluate levels of unintended chemical constituents in paperboard or containerboard and contains information on how to use the test data. In addition, it establishes a process for further evaluations should test results deem additional study is needed.

RPTA selects chemicals for inclusion in the Protocol based on the potential for their presence in recycled fibers because they are common industrial and commercial contaminants. Classes of chemicals contained in the list include:

  • Azo Colorants/Degradation Products
  • Heavy Metals
  • PCB’s
  • Pesticides
  • Phthalates
  • Polycyclic Aromatic Hydrocarbons
  • Semi-Volatile Organic Compounds
  • Volatile Organic Compounds

The list of chemicals contained in the Protocol is not static. Based on information from the U.S. Environmental Protection Agency, FDA, the US Department of Agriculture and other government and quasi-government entities, RPTA periodically revises the list to include new chemicals which could potentially be found in recycled fiber streams and have potential health effects. In addition, the allowable concentrations are subject to change as new information about any health effects becomes available. RPTA monitors changes to the underlying toxicological data used to develop the allowable concentrations for the chemicals, and updates the information contained in the Protocol as necessary. The 2023 Comprehensive Program is the eighth update to the original Protocol document.

RPTA Comprehensive Program Certification

In 2017 the RPTA began a program to certify each of its member mills was implementing the comprehensive program fully and consistently. RPTA partnered with NSF to develop a certification scheme and to provide auditing services. The audit is a robust, onsite review of member mill procedures and documentation ensuring proper, thorough and consistent adherence to all aspects of the comprehensive program.

The RPTA certifies that each member mill certificate holder has processes in place to produce product which meets the stipulations of the RPTA Comprehensive Program for Food-Contact Paperboard Produced from Recycled Fiber and certifies that the management and manufacturing systems of the certificate holder have been audited and found to be in accordance with the requirements of Recycled Paperboard Technical Association: Comprehensive Program for Food-Contact Paperboard Produced from Recycled Fiber.

Conclusion

The Comprehensive Program for Food-Contact Paperboard and Containerboard Produced from Recycled Fiber is a confidential and proprietary tool that helps RPTA members comply with FDA's requirements for manufacturing food-contact packaging. The RPTA Comprehensive Program is a living document. RPTA draws on the knowledge of recognized experts in the field of risk assessment, authoritative scientific literature, and commonly accepted safety assessment techniques to present a methodology for achieving this purpose.

The Comprehensive Program is a licensed product of RPTA. It is available only to RPTA members and licensees. For information on becoming a RPTA member please contact Paul Schutes at pschutes@rpta.org.


LATEST NEWS

2023 Industry Profile Study
The 2023 Industry Profile Study has been published and distributed to members. The study included 209 grade samples off 65 paper machines at 47 RPTA-member mills. Members can access this report, and prior year reports, at this member-only page. Each member company also received custom, confidential Excel workbooks by email with the samples from their paper machines identified.

Narrow Roll Safety Guideline
Narrow rolls, also known as ribbon rolls, represent a heightened risk of injury due to their unstable configuration. A task team of RPTA members developed a guideline that provides options that mills may consider to protect employees who handle narrow rolls, or will be in the vicinity of narrow rolls. The Guideline is available at this web page.

Summer 2023 Webinar
On July 20th we held a webinar on Treatment Technologies for Wastewater Reuse, presented by Everett Gill and Kristen Jenkins of Brown and Caldwell Engineering. The webinar covered technologies that can reduce the concentration of one or more chemicals in process water or mill effluent. Presentation slides and recordings from the webinar are available to RPTA members only at this web page.
