Learn what butter paper is, how it differs from greaseproof and parchment paper, where it is used and what makes it suitable for food contact.
Ask for butter paper in an Indian kitchen, bakery or packaging shop and you may come across different kinds of paper sold under the same name. Some sheets are used to wrap sandwiches and bakery products, while others are sold for lining trays or handling greasy foods.
This is because butter paper is often used as a general name for grease-resistant food paper rather than one single packaging structure. What matters more is how the paper has been made, whether it has been coated or treated, and what conditions it is actually designed to handle.
A paper used around a sandwich has a very different job from one used in an oven or around a product expected to remain packed for several weeks. Understanding those differences helps us choose the right paper rather than relying only on the name printed on the pack.
Butter paper is mainly associated with grease resistance
The name makes sense when we look at its original purpose. Butter and other fatty foods can quickly soak through ordinary paper, so wrapping them requires paper that can resist oil for long enough to handle and store the product.
Grease-resistant papers are also used around bakery products, cheese, confectionery, sandwiches and similar foods. A detailed overview of paper-based food packaging describes greaseproof paper as a dense paper used particularly for butter and other fat-containing foods.
The important point is that grease resistance can be created in different ways. Some papers achieve much of it through the structure of the fibres themselves, while others depend more heavily on a coating or surface treatment. Two sheets that look similar can therefore behave quite differently once they come into contact with oil, moisture or heat.
Greaseproof paper gets much of its performance from its fibre structure
Traditional greaseproof paper is made by refining cellulose fibres extensively so that they become more closely packed. This reduces the pathways through which oil can travel and creates a smoother, denser sheet.
A technical review of greaseproof paper technologies describes two long-established approaches to grease resistance: highly refining the fibres and parchmentising the paper. Both approaches change the paper structure rather than simply placing a thick plastic film over it.
This is why greaseproof paper may be suitable for wrapping butter, baked goods or moderately oily foods even without a conventional plastic laminate. However, grease resistance alone does not mean the paper is a strong barrier against oxygen or water vapour, nor does it automatically make the sheet suitable for high-temperature cooking.
Parchment paper is designed with heat in mind
Parchment paper is often confused with butter paper because both can resist grease and are commonly found around food. Their intended uses, however, can be quite different.
Parchment used for baking is designed to tolerate elevated temperatures and provide a surface from which food can be released relatively easily. This makes it useful for lining baking trays, cake tins and similar cooking applications.
Butter or grease-resistant wrapping paper may not have the same heat tolerance. A sheet that works perfectly well around a sandwich, burger or pastry should therefore not automatically be assumed to be oven-safe simply because it looks similar to parchment paper.
For food businesses, this difference is important. The intended temperature, duration of contact and type of food should determine which paper is selected, rather than using “butter paper” and “parchment paper” as interchangeable terms.
Wax paper relies more directly on a surface coating
Wax paper takes another route. Instead of relying mainly on a dense fibre structure, the paper has a wax coating that improves its resistance to moisture and grease and can reduce sticking.
This can make waxed paper useful for selected food-wrapping and storage applications, but the coating also changes how the paper behaves around heat. Wax can soften or melt at temperatures used for baking, which is why wax paper should not automatically be substituted for oven-safe parchment.
The comparison shows why it is useful to look beyond the base material. All three products may begin with paper, but refining, parchmentising, waxing or applying another coating can completely change how the finished sheet performs.
Food safety depends on the complete paper structure
Whether a product is called butter paper, greaseproof paper or parchment, food-contact suitability depends on the finished material rather than simply the fact that it is made from paper.
India's current FSSAI Packaging Regulations include specifications for greaseproof paper, vegetable parchment, wrapping paper and other paper products intended for food contact. They also require direct food-contact paper and board to be food grade, suitable for its intended use and free from contaminants.
The coating matters as well. The FDA's food-contact guidance treats substances applied to packaging surfaces, including coatings, adhesives and colourants, as part of the food-contact system.
This means a food brand should know more than the GSM or colour of the paper. It should understand what treatment has been used, whether that treatment is appropriate for the intended food and whether the finished material has been assessed for the conditions in which it will actually be used.
The chemistry behind grease resistance matters
Paper that resists a samosa, croissant or other oily food is clearly doing something ordinary paper cannot. For brands, the useful question is what creates that performance.
Historically, some paper and paperboard food packaging used PFAS-containing grease-proofing treatments because they were highly effective at resisting oil, grease and water. In the United States, these uses have now been phased out, and the FDA's current PFAS guidance notes that the related grease-proofing substances are no longer authorised for paper and paperboard food packaging.
Grease resistance today can come from the structure of the paper itself or from other treatments and coatings. The choice affects more than whether an oil stain appears. It can also influence food-contact suitability, heat behaviour, moisture protection and what can realistically happen to the paper after use.
Choosing butter paper starts with how it will be used
For simple short-term wrapping, a grease-resistant food paper may be enough. A bakery product, sandwich or dry snack may not need the same level of protection as a food that remains packaged for weeks or months.
Oily foods introduce stronger grease requirements, while high-temperature use requires a paper specifically designed for those conditions. If the packaging needs to keep moisture or oxygen away from the food for a longer shelf life, basic butter or greaseproof paper may no longer provide enough functionality on its own.
This is why brands should look at the food, temperature, contact time, storage conditions and required shelf life before deciding which paper structure to use. The name “butter paper” is less useful than understanding exactly what the paper is expected to do.
Functional coatings can take paper beyond basic wrapping
At Pippa, we approach paper from this functional perspective. Rather than focusing only on grease resistance, our bio-based coating is designed to give paper several packaging properties within the same coated structure.
The coating is made using agricultural waste streams and provides oil and grease resistance along with water and oxygen barriers and heat-sealing properties. Pippa is also positioned as PFAS-free and microplastic-free, with further information available through Pippa's material technology.
This is a different requirement from a simple sheet of butter paper used to wrap a pastry or line a food container. Flexible packaging intended to protect a product for longer periods may need stronger barriers and reliable sealing in addition to grease resistance.
That is why understanding butter paper is ultimately about understanding what has been done to the paper. The fibres provide the base, but the way they are processed, treated or coated determines whether the finished material can actually handle the food and conditions it was chosen for.

Butter paper is a grease-resistant food paper commonly used for wrapping bakery products, sandwiches, cheese, butter and other foods that may release oil or fat.
2. Is butter paper the same as greaseproof paper?
The terms are often used interchangeably, especially in India, but they are not always technically identical. Greaseproof paper is specifically made to resist oil and grease.
3. What is the difference between butter paper and parchment paper?
Butter paper is mainly associated with grease-resistant wrapping, while parchment paper is generally designed for baking and higher-temperature applications.
4. Can butter paper be used for baking?
Not all butter paper is oven-safe. Only paper specifically designed and rated for baking temperatures should be used in an oven.
5. Is butter paper food-safe?
Butter paper can be food-safe when the finished material is suitable for direct food contact and meets the relevant food-contact requirements.
6. Why does butter paper resist grease?
Grease resistance can come from a dense fibre structure, parchmentising, wax, silicone or another functional coating or treatment.
