The Truth About Kraft Paper in Food Packaging: Safe or Not?

Kraft paper has become a familiar sight in modern food packaging. From bakery bags and sandwich wraps to takeaway boxes and coffee sleeves, its natural appearance and perceived sustainability have made it a popular choice across the food industry. As one of many commonly used food packaging materials, kraft paper is often associated with eco-friendly branding and simplicity.
However, a common and important question remains: Is kraft paper actually safe for food packaging?
The answer is not a simple yes or no. While kraft paper can be safe for direct food contact, its safety depends on how it is made, what additives or coatings are used, and whether it complies with food contact regulations.
This article takes a practical, regulation-based look at kraft paper in food packaging—examining its safety, benefits, limitations, and how to choose the right option for food use.

1. What Is Kraft Paper — And Why Safety Matters in Food Packaging

1.1 What Is Kraft Paper and How It Is Made

Kraft paper is produced using the kraft pulping process, a chemical method that separates cellulose fibers from wood using sodium hydroxide and sodium sulfide. This process preserves longer fibers, resulting in paper that is stronger and more tear-resistant than many other paper types.

Kraft paper can be:
•Unbleached, retaining its natural brown color
•Bleached, processed further to achieve a light

The base material itself is not inherently unsafe. However, food safety depends on what happens after the paper is made, including additives, inks, coatings, and handling.

1.2 Why Kraft Paper Became Popular in Food Packaging

Kraft paper gained popularity due to its strength, affordability, and natural appearance. It provides breathability for fresh items while supporting sustainable sourcing from renewable forests. Brands favor it for reducing plastic use and appealing to eco-conscious consumers.

1.3 Common Types of Kraft Paper Used in the Food Industry

Food packaging commonly features unbleached natural brown kraft for rustic appeal, bleached white kraft for clean looks, and coated variants with wax or polyethylene for added moisture resistance. Specialized butcher-style kraft handles direct meat contact effectively.

2. Is Kraft Paper Safe for Food Contact? (Quick Answer First)

2.1 Short Answer: When Kraft Paper Is Safe — and When It Is Not

Kraft paper is safe for food packaging only when it is specifically manufactured and certified for food contact.

It is not automatically food-safe simply because it is made from paper.
Food-safe kraft paper must:
•Use approved raw materials
•Avoid harmful additives
•Comply with food contact regulations
•Pass migration and contamination testing

Using non-food-grade kraft paper for direct food contact can pose risks such as chemical migration, odor transfer, or contamination.

2.2 Key Factors That Determine Food Safety (Pulp, Additives, Coatings)

 Virgin pulp minimizes contaminants compared to recycled sources, which may introduce inks or glues. Food-grade additives like wet-strength resins must meet migration limits. Coatings such as polyethylene or silicone require approval for no toxic transfer. Production in clean environments prevents bacterial contamination. Testing simulates food types, temperatures, and contact times to measure substance release. Low migration thresholds protect consumers. Pulp purity avoids heavy metals or dioxins. Approved bleaching agents prevent chlorine residues. Barrier coatings block oil but must remain inert. Overall equipment cleanliness and good manufacturing practices ensure final safety.

3. Food Contact Safety Standards and Regulations

3.1 FDA Regulations for Kraft Paper in the United States

The FDA regulates paper under 21 CFR 176.170 and 176.180, requiring no harmful substance migration. Compliant kraft paper earns approval for direct contact after rigorous testing by manufacturers.

3.2 European Union and Other Global Food Contact Standards

EU Regulation (EC) No 1935/2004 sets general safety rules, with Good Manufacturing Practices under (EC) No 2023/2006. National guidelines, like Germany’s BfR, often apply since no specific harmonized paper rule exists.

3.3 Bleached vs. Unbleached Kraft Paper: Safety Differences

Both types prove safe when food-grade certified. Unbleached retains natural color with fewer chemicals, while bleached uses controlled processes to avoid residues. Certification ensures neither transfers harmful substances.

3.4 Food-Grade Testing, Certification, and Compliance

Testing includes migration studies simulating food contact. Certifications like FDA compliance, BRC, or FSC verify safety and sustainability. Suppliers provide declarations of conformity for traceability.

4.  Benefits of Kraft Paper for Food Packaging

Recycled variants potentially carry contaminants. Virgin pulp essential for direct contact. Mislabeling confuses buyers. Verification through certificates critical. Non-compliant use invites regulatory issues.

5.2 Moisture, Grease, and Oil Absorption Issues

Uncoated kraft absorbs liquids readily, leading to weakening or leaks. Grease soaks through without barriers. Wet foods cause sogginess quickly. High humidity softens structure. Oily items stain and compromise integrity. Coatings needed for fatty applications. Absorption risks bacterial growth. Limited standalone for liquids.

5.3 Heat Resistance and Temperature Limits

Plain kraft chars or weakens above moderate heat. Oven use risks scorching without treatment. Microwave exposure may ignite uncoated types. Prolonged high temperatures degrade fibers. Limited for direct baking. Specialized heat-resistant variants required. Freezer tolerance varies. Thermal limits constrain hot-fill uses.

5.4 Printing Inks, Odor Transfer, and Aesthetic Constraints

Non-food-safe inks migrate potentially. Natural brown limits vibrant colors. Odor absorption from surroundings affects contents. Rough surface challenges fine printing. Bleaching needed for white base. Glossy finishes require extra processing. Aesthetic suits rustic but not luxury uniformly.

6. Kraft Paper vs Other Food Packaging Materials

6.1 Kraft Paper vs Plastic Packaging

Kraft biodegrades naturally while plastics persist environmentally. Breathability preserves freshness better than airtight plastics. Kraft offers renewable sourcing versus fossil fuels. Plastics provide superior barriers for liquids. Kraft reduces microplastic risks. Recyclability higher for paper streams. Consumer preference shifts toward kraft sustainability.
