Food packaging paper is a specialty paper substrate engineered to come into direct or indirect contact with food. Unlike ordinary printing or writing paper, it is manufactured, coated, and certified to resist grease, moisture, and bacterial contamination while remaining safe for human consumption contact. It is the material behind sandwich wraps, bakery bags, burger wraps, deli paper, butcher paper, and the paper layer inside many food labels and cartons. Understanding how it is made, tested, and selected is essential for brand owners, packaging engineers, and procurement teams who need to balance food safety, cost, and sustainability.

As a manufacturer supplying Paper Series Products and Special Paper Series Products for food-contact and label applications, we've put together this guide to walk through the composition, technical properties, compliance requirements, and selection criteria for food packaging paper — based on our production experience and current industry practice.

1. What Food Packaging Paper Is Made Of

Food packaging paper starts from a base substrate — most commonly virgin or recycled kraft pulp, offset paper, or greaseproof (glassine-type) paper. On its own, plain paper is porous and cannot block oil or moisture, so a functional coating or treatment is applied to one or both sides. The three most common approaches are:

• Greaseproofing / super-calendering: The paper fibers are highly refined and compressed, closing the pores mechanically so oil cannot penetrate. No chemical coating is required, which makes this the simplest option for recyclability.

• PE (polyethylene) lamination or coating: A thin polyethylene film is extruded onto the paper to create a strong moisture and grease barrier. This is common for wrap papers and cup stock, though it reduces recyclability unless the PE layer is separated at the recycling stage.

• Silicone coating: Applied where a release surface is needed (e.g., baking paper or the release liner behind an adhesive label), silicone allows food or adhesive to lift cleanly without sticking.

We manufacture several of these constructions directly — see our PE Coated Paper & Silicon Paper Series Products for coated and release-liner options used across food, label, and industrial applications.

4. Key Technical Properties & Test Values

Buyers evaluating food packaging paper should ask suppliers for data on the following parameters, which are the standard technical benchmarks used in the paper and packaging industry:

5. Safety & Regulatory Compliance

Because it touches food directly, packaging paper is regulated more strictly than general paper products. Common compliance references in the industry include:

• FDA food-contact substance requirements (United States): govern which raw materials and coatings are approved for direct food contact.

• EU Regulation on materials intended to come into contact with food: sets migration limits and material traceability requirements across the European Union.

• LFGB (Germany): a widely referenced sensory and safety standard for food-contact materials sold into the German and broader EU market.

• ISO 9001 quality management certification: confirms the manufacturer's production process is consistently controlled and documented.

When sourcing food packaging paper, always request current test reports and certificates directly from the supplier rather than relying on general marketing claims — compliance status can vary by grade, coating type, and production batch.

6. Choosing the Right Grade for Your Application

If food packaging paper is being used as a label rather than a wrap, our Paper Series Products line covers glossy coated, semigloss, offset, kraft, aluminum foil, and fluorescent surface materials suited to food, beverage, and industrial label applications.

7. Sustainability Considerations

Uncoated and greaseproof papers are generally the most recyclable and compostable, since they contain no plastic film. PE-coated papers offer stronger barrier performance but require separation at specialized recycling facilities to be processed correctly. Buyers focused on sustainability goals should weigh barrier performance needs against end-of-life recyclability, and ask suppliers about FSC or PEFC-sourced pulp where traceable sourcing is a priority.

Frequently Asked Questions

Is all food packaging paper recyclable?

No. Uncoated greaseproof paper is typically recyclable and often compostable, while PE-coated or foil-laminated papers require specialized recycling processes to separate the paper and film layers.

What's the difference between food packaging paper and a food label?

Food packaging paper wraps or contains the food directly, while a food label is typically an adhesive-backed paper applied to the outside of packaging for branding and information. Both require food-safe materials, but labels have different adhesive and print requirements — see our Paper Series Products for label-grade options.

How do I verify a supplier's food-safety compliance?

Request current test reports for migration levels, grease resistance, and any applicable regional certifications for the specific grade and batch you intend to purchase, rather than relying on general product descriptions.
