Most people think getting the best price per kg and accurate GSM value is the right way to buy grease-resistant paper. However, its performance cannot be predicted based on just two factors. Such as two similar rolls with the same GSM can behave differently and possess varying strength. That’s why, choosing the right food container paper is crucial to keep the food fresh and prevent leakages. The real difference between premium grade and regular paper is revealed when the paper packaging is exposed to hot oil and moisture. It all comes down to the quality of coating, material type, and fiber density. This guide explains how to buy the best quality grease-resistant food container paper. It explains how to match the right specifications to your application for producing the best quality food packaging materials.
What Actually Makes the Food Container Paper Grease Resistant?
Grease resistance in the paper comes from the fiber density and the type of coating it has:
Natural Grease Resistance: It depends on the paper density. During the paper manufacturing process, the fibers are packed tightly, which reduces the gaps and makes it grease-resistant, so that oil cannot pass through. With the help of this process, even the uncoated food container paper provides protection against moisture and liquids.
Grease Resistance From Coatings: This type of resistance comes from different coatings applied to the paper. Polyethylene (PE) laminate and water-based oil-and-grease-resistant (OGR) coatings are the most common options used by the paper manufacturers. Food container papers also require coating when used for making cups and pouches that include a heat sealing process.
Another essential factor that defines the oil-resistant ability of the paper is KIT value. It ranges between 1-12 and higher; the higher the value, the more resistant the paper is to oil and moisture. KIT value is considered a helpful factor, even more than GSM value, if you are procuring paper that requires higher grease-resistance.
Food Container Paper GSM Guide
GSM value provides the information about the softness of the paper and how much it is resistant to grease and moisture. A higher GSM value does not necessarily mean better performance. It's just that the value is to be perfect for the application.
GSM Range | Typical Application | Grease Resistance Need |
30-40 GSM | Sandwich wraps, burger wraps, light liners | Moderate: short contact time |
40-60 GSM | Paper cups, tray liners, bakery bags | Moderate to high: sustained contact |
60-91+ GSM | Rigid containers, boxes, pizza bags | High: heavier, oilier food, longer hold time |
Remember, lighter GSM value food container paper is best for making quick-service materials that do not come in contact with food for long. Further, cups, tubs, pizza boxes, and other packaging materials that hold oil- and moisture-containing foods should be made using higher GSM paper for higher structural integrity.
Which One to Consider: Coated or Uncoated Food Container Paper?
Paper Type | Best For | Key Benefits | Things to Consider |
Uncoated Paper | Dry snacks, bakery items, light wraps | • Plastic-free • Compostable • Naturally grease-resistant | • Moderate grease resistance • GSM and KIT Value are important |
PE-Coated Paper | Cups, pouches, hot foods | • High grease resistance • Moisture-resistant • Heat-sealable | • Less eco-friendly • May affect recycling claims |
Water-Based OGR - Non-Heat-Sealable | Plates, wraps, flat packaging | • Oil-resistant • Plastic-free option • Suitable for flat formats | • Cannot be heat-sealed • Check grease resistance |
Water-Based OGR - Heat-Sealable | Cups, pouches, food containers | • Grease-resistant • Heat-sealable • Suitable for forming | • Must match equipment • Check sealing performance |
Specifications of Food Container Paper for Different Paper Products
Cups and hot beverage containers: You can choose food container paper with a 60+ GSM value. It can be PE-coated or have an OGR coating for holding hot and moist beverage items.
Sandwich and burger wraps, bakery bags: Choose 30-50 GSM, uncoated or lightly coated based on grease load and compostability requirements.
Pizza bags and boxes: Select 60-91 GSM, coated to handle sustained oil and moisture contact.
Trays, plates, disposable containers: 40-80 GSM is ideal depending on size and food type, with non-heat-sealable OGR coating for flat-format performance.
A Checklist to Bulk Buy the Best Quality Grease Resistant Food Container Paper
- KIT Value: A rating that shows actual grease resistance performance of the paper, different from GSM value.
- GSM Value: Shows the stiffness and strength of the paper to hold oily and moist food items and beverages. Make sure it is consistent across all batches.
- Coating and Heat-Seal Compatibility: Choose the most appropriate coating that fits your manufacturing process and product.
