Sustainable Packaging
Learn about food wrapping paper, greaseproof and parchment paper, food-contact safety, coatings and what brands should check before choosing paper.
Wrap a sandwich, line a bakery box or pack an oily snack and the paper may look like the simplest part of the packaging. In reality, paper that comes into direct contact with food can have a demanding job.
It may need to resist grease, tolerate moisture, retain enough strength to hold the food and remain suitable for direct food contact throughout its intended use. This is why food wrapping paper is different from ordinary paper.
A sheet that works for wrapping bread may not be suitable for butter, fried food or a product expected to remain packed for several months. The type of paper, how it is manufactured and anything added to its surface all influence what foods it can safely and effectively be used with.
Different food wrapping papers solve different problems
Kraft paper is one of the most familiar papers used in food packaging because it is strong, flexible and easy to print and convert. It can work well for bags, liners and wrappers, particularly for relatively dry foods.
However, untreated kraft paper does not naturally provide a strong barrier against oil or moisture. Foods containing grease, sauces or higher moisture may therefore need a treatment, coating or a different paper structure.
Greaseproof paper is designed with oily foods in mind. It is commonly used around bakery products, snacks, butter, cheese and other foods where ordinary paper would quickly develop visible oil patches.
Its resistance can come partly from creating a dense fibre structure that makes it harder for grease to move through the sheet. Some food papers also use coatings or surface treatments when additional performance is needed.
Parchment paper has another role. Most of us know it from baking, where it needs to tolerate heat while providing a surface that food does not easily stick to.
Parchment, baking paper and greaseproof paper are sometimes used almost interchangeably in everyday conversation, but they are not necessarily produced in the same way or intended for the same conditions. A paper suitable for a baking tray is therefore not automatically the right material for a food wrapper or sealed flexible pack.
Food-safe paper is about more than the paper itself
The term food grade paper can sound as though it simply means clean paper made for food. In practice, food-contact suitability involves the complete material and the conditions in which it will be used.
India's current FSSAI Packaging Regulations require materials coming into direct contact with food to be of food-grade quality and suitable for their intended use. The regulations also require paper and board used for direct food contact to meet applicable standards and be free from contaminants.
They also make some very practical distinctions. Printed surfaces should not directly touch food, and newspaper should not be used for storing or wrapping food.
This shows why ordinary paper and food wrapping paper are not interchangeable. Suitability depends on what the finished material contains and how it will interact with the food.
Coatings can change what paper is able to do
Paper on its own has natural limitations, especially when it comes to oil, moisture and gases. Applying a functional coating can change the way the surface behaves and make paper suitable for more demanding applications.
Waxed paper is one familiar example. Wax can improve resistance to grease and moisture and reduce sticking for certain foods. Modern coating technologies can go further by adding oxygen barriers, water-vapour resistance or heat-sealing properties.
This is important because a paper wrapper may look simple while relying heavily on its surface treatment for performance. The coating can determine whether the paper remains clean around an oily product, whether moisture moves through it and whether the material can be sealed into a pouch.
Food brands therefore need to understand not only the base paper, but also what has been added to make that paper functional.
Grease resistance depends on the chemistry behind it
Grease is one of the most obvious challenges for food wrapping paper. Place a samosa, buttery bakery product or oily snack on untreated paper and the oil can quickly move into the fibres.
Historically, some paper food packaging used PFAS-containing treatments because these substances were highly effective at resisting oil and grease. In the United States, those grease-proofing uses have since been phased out, as explained in the FDA's current PFAS guidance.
For brands, this creates an important question whenever a paper is described as greaseproof: what is actually creating that resistance?
Depending on the product, it may come from the fibre structure, wax, silicone, a polymer coating or another treatment. That choice can affect not only performance but also food-contact suitability and what can realistically happen to the packaging after use.
The right wrapping paper depends on the food
A bakery wrapper does not have the same job as paper around an oily snack. A liner for dry biscuits has different requirements from a wrapper touching cheese, butter or a moist takeaway product.
Contact time matters too. Paper used around a sandwich that will be eaten within an hour has a different job from flexible packaging expected to hold a product for several months.
Temperature also changes the requirement. A paper used at room temperature is not automatically suitable for baking, reheating, freezing or other more demanding conditions.
This is why choosing wrapping paper for food only by GSM, colour or appearance can be misleading. The food type, grease and moisture levels, contact time, storage conditions and required shelf life all need to be considered together.
Functional coatings are expanding the role of paper
One of the more interesting changes in paper packaging is that we no longer need to judge paper only by what untreated fibres can do. Functional coatings can give paper properties that allow it to move into applications that traditionally relied on additional plastic films or other materials.
At Pippa, this is where our approach comes in. Our bio-based coating is made using agricultural waste streams and applied to paper or biofilm substrates.
The coating is designed to provide oil and grease resistance along with water and oxygen barrier performance and heat-sealing functionality. Pippa is also positioned as PFAS-free and suitable for food-contact applications, with more information available through Pippa's packaging technology.
That does not mean one coated paper should be used for every food. A dry bakery product, oily snack and moisture-sensitive product can all require different levels of protection and different testing.
Food wrapping paper may look simple, but its performance depends on much more than the fibres we can see. The base paper provides the structure, while the way it is processed, coated and tested determines whether it is suitable for the food it was designed to wrap.
FAQs
1. What is food wrapping paper?
Food wrapping paper is paper designed for direct or indirect contact with food. Depending on the application, it may also provide grease, moisture or heat resistance.
2. What type of paper is safe for wrapping food?
Paper used for food should be food-grade, suitable for the intended use and free from contaminants. The coating, inks and other treatments also need to be suitable for food contact.
3. Is kraft paper safe for food wrapping?
Food-grade kraft paper can be used for some foods, especially dry products. Oily or moist foods may require additional grease or moisture resistance.
4. What is the difference between greaseproof paper and parchment paper?
Greaseproof paper is designed mainly to resist oil and grease, while parchment paper is typically treated to provide heat resistance and a non-stick surface.
5. Can ordinary paper be used to wrap food?
Not necessarily. Ordinary paper may contain inks, contaminants or treatments that are not suitable for direct food contact.
6. Why is food wrapping paper coated?
Coatings can give paper extra properties such as grease resistance, moisture protection, oxygen barrier performance or heat-sealing ability.
7. Is food wrapping paper plastic-free?
Not always. Some paper wrappers may contain plastic films, polymer coatings or other functional layers, so the complete material structure should be checked.
8. What makes food wrapping paper grease-resistant?
Grease resistance can come from a dense fibre structure or from treatments such as wax, silicone or functional coatings.
9. Is Pippa suitable for food wrapping applications?
Pippa uses a bio-based coating designed to provide oil, grease, water and oxygen barrier performance while remaining suitable for food-contact applications.
10. Is Pippa food wrapping paper PFAS-free?
Pippa is positioned as PFAS-free and uses a bio-based coating made from agricultural waste instead of conventional fluorinated grease-proofing chemistry.
