AI Summary
Vacuum sealing bags used for food in the United States must meet the requirements of the Food and Drug Administration under Title 21 of the Code of Federal Regulations, primarily Parts 174 through 178, which govern indirect food additives and substances that come into contact with food. This means every resin, adhesive, and additive used in a multilayer vacuum bag, including common structures built from polyamide, polyethylene, and EVOH, must either be listed as an approved food contact substance, recognized as Generally Recognized as Safe, covered by a Food Contact Notification, or fall under a Threshold of Regulation exemption. Manufacturers must also follow current Good Manufacturing Practice and, for products intended for retort or boilable applications, demonstrate that the film performs safely under sustained heat and pressure. This article explains what these requirements mean in practice for buyers of vacuum sealing bags, referencing the actual FDA regulation parts, and describes how Vishakha Polyfab aligns its VISHVACU vacuum pouches and bags with these standards.
Understanding the FDA Framework for Food Contact Materials
In the United States, packaging materials that touch food are regulated as indirect food additives rather than as separate consumer products. The FDA’s Code of Federal Regulations Title 21 sets out the framework for this. According to the FDA’s own inventory of food contact substances, materials used to manufacture food packaging fall under Part 174, which lays out general provisions, with more specific rules in Parts 175 through 178 and additional listings in Part 179.45 and Part 180.22.
For a vacuum sealing bag to be considered compliant, every substance in its construction, including the base resins, any adhesive used in lamination, colorants, and processing aids, must satisfy one of the following conditions.
- It is specifically listed as an approved indirect food additive under 21 CFR Parts 175 to 178 for its intended use.
- It is Generally Recognized as Safe, commonly referred to as GRAS, for use in food contact applications.
- It is authorized through an effective Food Contact Notification, referred to as an FCN, submitted to the FDA for that specific substance and use.
- It qualifies under a Threshold of Regulation exemption for substances that migrate into food only at negligible levels, as described under 21 CFR 174.6.

What FDA Compliance Actually Requires From a Vacuum Bag Manufacturer
FDA compliance for a finished vacuum bag structure is not a single certificate but a chain of documentation covering every material in the pack.
- Resin compliance, confirming that the base polymers such as PE and PA nylon meet the specifications and extractable limits defined in their respective CFR sections, most commonly 21 CFR 177.1520 for polyolefins and 21 CFR 177.1360 for EVOH.
- Adhesive compliance, confirming that any lamination adhesive used to bond layers together is authorized under 21 CFR Part 175 for food contact use.
- Additive compliance, confirming that colorants, slip agents, and antiblock agents used in film production are permitted under the applicable additive regulations.
- Good Manufacturing Practice, since 21 CFR 174.5 requires that food contact substances be used under conditions of good manufacturing practice, meaning the amount used must not exceed what is reasonably required to achieve the intended technical effect and must not adulterate the food.
- Documentation, typically provided to buyers as a Letter of Guarantee or Certificate of Compliance stating that the specific film structure is manufactured from FDA compliant materials for its stated end use.

Special Requirements for Boilable and Retort Vacuum Bags
Vacuum bags intended for sous vide cooking or retort sterilization face an additional layer of scrutiny because they are exposed to sustained heat, sometimes reaching sterilizing conditions well above boiling temperature for extended periods. Beyond confirming that the resins themselves are approved for food contact, manufacturers must demonstrate that the finished film maintains its seal integrity and does not release its components in excess of established migration limits when exposed to these conditions. Research on EVOH barrier films indicates that EVOH maintains its barrier function and chemical stability at retort conditions up to around 135 degrees Celsius, which is one reason EVOH based structures are widely specified for boilable and retortable vacuum pouches rather than materials that may soften or degrade at high temperature.
Global Context, How FDA Compares to Other Food Contact Regulations
While this article focuses on the United States FDA framework, vacuum bag manufacturers that export internationally also need to align with regional equivalents.
| Region | Governing Framework | Key Requirement |
| United States | FDA, Title 21 CFR Parts 174 to 178 | Approved substances, GRAS status, or FCN authorization |
| European Union | Regulation EC No 1935/2004 and Regulation EU No 10/2011 | Specific migration limits and declaration of compliance |
| India | Food Safety and Standards Authority of India packaging regulations | Food grade material standards under the Food Safety and Standards Act |
Manufacturers supplying multiple markets typically design films to meet the strictest applicable migration limits across these frameworks so a single structure can serve both domestic and export customers without redesign.
Questions to Ask a Vacuum Bag Supplier About FDA Compliance
- Can you provide a Letter of Guarantee or Certificate of Compliance confirming the specific resins used meet 21 CFR Part 177 requirements.
- Is the lamination adhesive used in this structure authorized under 21 CFR Part 175 for food contact.
- Has the film been tested for migration limits under the intended use temperature, particularly for boilable or retort applications.
- Is the manufacturing facility operating under a recognized quality system such as ISO or BRCGS, which supports consistent Good Manufacturing Practice.

How Vishakha Polyfab Can Help
Vishakha Polyfab manufactures its VISHVACU vacuum pouches and vacuum bags using PA and EVOH based co extruded films under ISO and BRCGS certification, and states that its PA EVOH based films comply with applicable safety regulations, making them suitable for direct food contact globally. Because the company controls its own extrusion, printing, and lamination process, it can provide the documentation buyers need to confirm that resins, adhesives, and processing aids used in a specific vacuum bag structure meet the applicable food contact requirements, along with boilable vacuum pouches engineered for high temperature stability for sous vide and retort style applications.
Conclusion
FDA compliance for vacuum sealing bags is built on a layered framework rather than a single blanket approval, covering the base resins, adhesives, and processing aids that make up the finished film. Understanding the relevant CFR parts, particularly Part 177 for plastics and resins and Part 175 for adhesives, helps food processors and packaging buyers ask the right questions and request the right documentation from their vacuum bag supplier. This is especially important for boilable and retort vacuum bags, where the film must remain stable and compliant under sustained heat rather than only at room temperature.
Frequently Asked Questions
Do vacuum sealing bags need FDA approval before they can be sold?
Vacuum sealing bags themselves are not individually approved as products. Instead, the food contact substances used to make them, such as the PE, PA nylon, or EVOH resins and any adhesives, must comply with the applicable regulations under 21 CFR Parts 174 to 178.
What is the difference between GRAS status and an FCN for a packaging material?
GRAS status means a substance is Generally Recognized as Safe for its intended use based on established scientific consensus, while a Food Contact Notification is a specific premarket authorization the FDA grants to a manufacturer for a defined use of a particular substance.
Is EVOH used in vacuum bags FDA compliant?
Yes, ethylene vinyl alcohol copolymers used as an oxygen barrier layer in vacuum bags are addressed under 21 CFR 177.1360, and EVOH is widely recognized as compliant with United States, European Union, and Japanese food contact regulations.
What documentation should a buyer request to confirm compliance?
Buyers should request a Letter of Guarantee or Certificate of Compliance from the manufacturer confirming that the specific resins, adhesives, and additives used in the vacuum bag structure meet the applicable FDA food contact regulations for the intended use.
Are boilable vacuum bags held to a higher standard than standard vacuum bags?
Boilable and retort vacuum bags face additional scrutiny because they are exposed to sustained high temperature, so manufacturers must confirm the film maintains seal integrity and stays within migration limits under those specific heat conditions rather than only at ambient temperature.
Does FDA compliance guarantee food safety on its own?
FDA compliance confirms the packaging material itself is safe for food contact, but overall food safety also depends on proper handling, storage temperature, and processing by the food producer, since packaging is one part of a larger food safety system.
