Food grade paper plays a crucial role in ensuring the safety and quality of packaged food products. Whether you’re a food manufacturer, retailer, or consumer, understanding what food grade paper is, what it is made of, and the standards it must meet is essential for choosing packaging that protects food from contamination while maintaining freshness. In Canada, strict regulations and certifications govern food grade paper to guarantee its safety for direct food contact. This article explores the definition, materials, regulatory framework, types, and coatings of food grade paper, helping you make informed decisions about food-safe packaging.
What is Food Grade Paper? Definition and Safety Standards in Canada
What is Food Grade Paper? – Definition and Importance
Food grade paper refers to paper products that are safe for direct contact with food. This means the paper is free from harmful chemicals, toxins, or residues that could contaminate food and pose health risks. Food grade paper is essential for preserving food quality, preventing contamination, and complying with health regulations, making it a trusted choice for packaging edible products.
What is Food Grade Paper Made Of? – Materials, Coatings, and Safety Compliance
Food grade paper is typically made from natural fibers like wood pulp, often processed to remove impurities. It may be coated or treated with substances that enhance its barrier properties, such as moisture resistance or greaseproofing, without compromising safety. Common coatings include polyethylene (PE), clay, or biobased coatings like zein or polylactic acid (PLA), which are compostable alternatives to plastics. All materials and coatings used must comply with safety standards to ensure they do not migrate harmful substances into food.
Regulatory Framework in Canada: Health Canada (Division 23), Letters of No Objection
In Canada, food grade paper packaging is regulated under the Canadian Food and Drugs Act and the Food and Drug Regulations (FDRs), specifically Section B.23.001, which sets safety requirements for food packaging materials. The Health Products and Food Branch (HPFB) of Health Canada oversees these regulations, conducting risk assessments and advising on packaging safety. While pre-market approval and "Letters of No Objection" from Health Canada are no longer mandatory for most food packaging materials, manufacturers remain responsible for ensuring their products are safe and compliant with food safety laws.
Certifications: FDA, FSC, Compostable vs Recyclable Standards
Food grade paper often carries certifications to validate its safety and sustainability credentials:
- The FDA (U.S. Food and Drug Administration) regulates food-contact materials to ensure they do not contaminate food, requiring migration testing and Good Manufacturing Practices.
- The FSC® (Forest Stewardship Council) certification guarantees that paper comes from responsibly managed forests.
- Compostable and recyclable certifications confirm that the paper packaging can be safely returned to the environment without harmful residues, supporting eco-friendly practices.

Types of Paper Used in Food Packaging: Properties and Composition
Overview of Types of Paper Used in Food Packaging and Their Classifications
Food packaging employs various types of paper, each with unique properties suited to different food products and packaging needs.
Kraft Paper: Natural, Strong, and Recyclable – Kraft Paper Food Packaging Use Cases
Kraft paper is a popular choice due to its strength, durability, and natural brown color. Made from softwood sulfate pulp, it is thick and tear-resistant, making it ideal for bags, wraps, and boxes. Kraft paper is recyclable and often FSC-certified, aligning with sustainability goals.
Greaseproof Paper: Oil Resistance for Burgers, Pastries
Greaseproof paper is treated to resist oil and grease, making it perfect for wrapping oily foods like burgers and pastries without leaking.
Wax Paper: Moisture Barrier, Coated on Both Sides
Wax paper is coated with wax on both sides to provide a moisture barrier, commonly used for wrapping moist or sticky foods.
Parchment Paper: Non-Stick and Heat-Resistant
Parchment paper is treated for non-stick properties and heat resistance, ideal for baking and cooking applications.
Glassine Paper: Smooth, Grease-Resistant, Translucent
Glassine paper is smooth and translucent with natural grease resistance, often used for delicate food items.
Paperboard (White-Lined or Solid Unbleached Board)
Paperboard offers structural support for packaging like cartons and trays, available in bleached or unbleached forms.
Molded Pulp: Eco-Friendly Trays for Fast Food, Produce
Molded pulp is an eco-friendly, biodegradable option used for trays and containers in fast food and produce packaging.
Paper Coatings and Surface Treatments
PE Coating and Polyethylene-Lined Paper: Moisture Barrier
Polyethylene coatings provide effective moisture barriers, extending shelf life and protecting food from humidity.
Clay-Coated Paper for Printing and Rigidity
Clay coatings improve print quality and add stiffness to paper packaging.
Zein or PLA Coatings: Compostable Alternatives to Plastic
Biobased coatings like zein (a corn protein) and PLA offer compostable, sustainable alternatives to traditional plastic coatings.
Barrier Technologies to Replace PFAS in Food-Grade Safe Paper
Emerging barrier technologies aim to replace PFAS chemicals, which are under scrutiny for health concerns, with safer, food-grade alternatives.
Comparison Between Paper Types
| Paper Type | Key Features | Best Use Cases | Recyclability & Cost |
|---|---|---|---|
| Kraft Paper | Strong, natural, recyclable | Bags, wraps, boxes | High recyclability, moderate cost |
| Wax Paper | Moisture barrier, coated both sides | Moist or sticky foods | Limited recyclability, low cost |
| Greaseproof Paper | Oil-resistant | Burgers, pastries | Recyclable, moderate cost |
| Paperboard | Structural support, printable | Cartons, trays | Recyclable, higher cost |
| Molded Pulp | Biodegradable, eco-friendly | Trays for fast food, produce | Compostable, cost-effective |
Kraft vs Wax Paper: When to Choose Which
Choose kraft paper for strength and recyclability; wax paper is better for moisture-sensitive foods.
Greaseproof vs Waxed Paper: Performance in Oily Foods
Greaseproof paper resists oil better than wax paper, making it preferable for greasy foods.
Paperboard vs Molded Pulp: Structure, Recyclability, Cost
Paperboard offers more rigidity and printability but may cost more; molded pulp is eco-friendly and cost-effective for disposable trays.
Understanding what food grade paper is, its materials, regulatory compliance, and types helps ensure safe, sustainable food packaging that meets consumer and legal expectations in Canada and beyond. Choosing the right paper type and coating can preserve food quality while supporting environmental responsibility.
