What is Food Safe Paper?
At its core, food safe paper is a specialized type of paper designed for direct contact with food products. It is specifically manufactured and treated to meet strict regulatory standards, ensuring it doesn’t pose any risks to human health. The primary objective of food safe paper is to act as a barrier, protecting food from external contaminants like bacteria, dust, and other environmental factors that can compromise food safety. It must also be inert, meaning it doesn’t react with the food it’s in contact with.
Food Contact Materials (FCMs), which includes paper, are regulated globally. These regulations aim to minimize the risk of harmful substances leaching into food. In the United States, the Food and Drug Administration (FDA) sets rigorous standards for all FCMs. These standards outline which materials can be used, the types of additives that are allowed, and the testing requirements to prove safety. European Union regulations also have similar stringent standards, with ongoing efforts to enhance food safety across all member states. Food safe paper manufacturers must rigorously adhere to these guidelines, ensuring that their products are safe for consumer use.
The key properties that define food safe paper are several:
Lack of Harmful Chemicals
The paper must be free from any chemicals that could migrate into the food and cause adverse health effects. This includes heavy metals, inks that contain toxic substances, and other potentially harmful compounds.
Oil and Grease Resistance
Many food products contain fats and oils. Food safe paper often needs to resist penetration from these substances to prevent leakage, maintain the food’s appearance, and extend its shelf life.
Preventing Contamination
The paper acts as a barrier against external contaminants. It’s engineered to prevent the transfer of any substances into the food and to inhibit the growth of bacteria that can lead to spoilage.
Odor and Taste Neutrality
It should not impart any unpleasant odors or tastes to the food, preserving its original flavors.
Controlled Porosity
The paper’s porous structure must be carefully controlled. Too much porosity allows moisture and oils to pass through, while insufficient porosity can hinder air circulation.
In contrast to food safe paper, regular paper might contain inks, dyes, or chemical additives that could potentially transfer to food. Non-food-grade papers are often manufactured with processes and materials that are not suitable for direct contact with edible products.
Types of Food Safe Paper
The diversity of food safe paper reflects the wide variety of food products and packaging needs. Let’s examine some of the most common types:
Wax Paper
Wax paper is a classic choice, instantly recognizable for its glossy, moisture-resistant surface. It’s produced by coating paper with paraffin wax or a similar wax mixture.

Wax paper is prized for its moisture resistance, which helps keep food fresh for longer, and its low cost, making it an affordable packaging solution for various applications. It’s also relatively easy to work with and widely accessible.
However, wax paper’s biodegradability is a potential environmental concern. The wax coating can hinder the decomposition process. Furthermore, it is not heat-resistant beyond low temperatures; it is generally not used in high-temperature cooking.
Parchment Paper
Parchment paper is a versatile option often used in baking and cooking. It’s produced by treating paper with sulfuric acid, which creates a smooth, dense surface that’s highly resistant to heat, moisture, and grease.
Parchment paper excels in its heat resistance, making it suitable for use in ovens up to moderate temperatures. Its non-stick properties are a significant advantage in baking, preventing food from sticking to the baking sheet and simplifying cleanup. It is also exceptionally versatile, finding applications from lining baking pans to creating cooking pouches.
On the other hand, parchment paper can be more expensive than other packaging options. While most parchment paper is compostable, the presence of silicone in certain types may inhibit composting.
Greaseproof Paper
Greaseproof paper, as its name implies, is specially designed to resist grease and oil penetration. This paper is typically manufactured with a dense structure or treated with coatings to prevent the migration of fats.
Greaseproof paper is essential for packaging greasy or oily foods, preventing unsightly stains and maintaining the product’s presentation. It’s commonly used in food service for burger wrappers, French fry containers, and other applications where oil resistance is essential. It can be customized with printing, allowing for branding and informational messaging.
Greaseproof paper’s quality can vary considerably depending on the manufacturing process and the specific coatings used. It’s essential to choose high-quality options to ensure optimal performance.
Kraft Paper and its Variants
Kraft paper, a strong and durable paper, is often used for bags and wrapping. It is made from wood pulp using the kraft process, a chemical pulping process that produces paper with greater strength.
Kraft paper is lauded for its strength, its biodegradability, and its ability to be made from recycled materials. It’s a common choice for brown paper bags, sandwich wraps, and packaging.
The main disadvantage of Kraft paper is its lower resistance to oil and grease compared to other specialized papers. It may require additional coatings or liners for optimal performance in certain applications.
