With the rapid development of the global catering and food delivery industries, food packaging is no longer just about holding food; it has become an important component that balances food safety, product performance, and sustainability.
This article will explain in detail which type of environmentally friendly food packaging restaurants, food processing companies, wholesalers, and other users should choose.
I. What are Bagasse and Kraft Paper?
1. Bagasse: A fibrous residue produced in the sugar industry. Through pulp molding, it is successfully made into various food packaging containers such as lunch boxes, trays, and plates.
Key Features:
- Raw Material: Bagasse from sugar production, 100% renewable and sustainable after use.
- Process: Pulping, molding, trimming, and sterilization are all done using physical methods, without the need for chemical adhesives.
- Appearance: Natural off-white or light brown, with a surface texture resembling plant fibers.
2. Kraft Paper: A type of paper primarily made from unbleached wood ginger. Packaging paper made through long-wire forming and high-strength calendering.
Core Features
- Raw Materials: Unbleached wood pulp from sustainably managed forests
- Process: Chemical pulping method retains lignin, forming a tightly interwoven fiber network
- Appearance: Natural brown, unbleached, free of any fluorescent agents
II. Comparison of Core Performance
1.Heat resistance
Bagasse can withstand a maximum temperature range of 220℃ and can be heated in a microwave oven. In the takeout industry, even after a bumpy journey, its structure remains intact without any leakage or odor release
The heat resistance of kraft paper depends on whether there is a coating layer on its surface. Essentially, it is an oil-absorbing paper. When exposed to hot soup or oil, it will quickly soften and leak
2. Water and Oil Resistance
Sugarcane bagasse is made from plant fibers under high pressure. Although it has a high density, its tiny pores still allow oil molecules to seep through. Kraft paper itself doesn't inherently possess oil and water resistance, but it can undergo food-grade coating processes to adapt to high-humidity, high-oil environments.
3. Structural Strength
The fibrous structure of sugarcane bagasse provides good rigidity and impact resistance, as well as excellent thermal insulation, maintaining the integrity of the overall structure. Kraft paper's advantages lie in its tear resistance and stiffness, better maintaining the structural rigidity of the sidewalls in stacked applications, reducing deformation and collapse.
4. Printing Effect
The surface of sugarcane bagasse has a natural texture, which can effectively conceal oil traces, but the printing clarity is not uniform, and it cannot clearly display brand logos, etc. Kraft paper has better printability and can be printed with water-based or soybean inks, resulting in better clarity of the finished product.

Products Description
Sugarcane Bagasse
- Hot soups, curries, stews, and other high-temperature, high-oil meals-heat resistant up to 220℃, structurally stable and non-collapse-resistant
- Meals requiring microwave heating-can be directly microwaved
- Frozen and refrigerated foods-can withstand freezing to -18℃
- Pursuing a "plastic-free" brand image-100% plant fiber, no plastic coating
- Outdoor catering, banquets, airline catering-durable and suitable for long-distance delivery
Kraft Paper
- Solid fast food such as hamburgers, sandwiches, and fried chicken-highly tear-resistant, sturdy and well-formed
- Salads, light meals, baked goods- -Highly breathable, neither stuffy nor damp
- Suitable for scenarios with strong brand display needs-excellent printing results, natural texture looks great on camera
- Short-distance delivery and dine-in takeout-controllable costs, meeting basic needs
- Prioritizing recyclability-kraft paper itself is recyclable
There's no absolute "better" between kraft paper and bagasse; the key is which better suits your menu. In today's rapidly developing food service industry with increasingly stringent global plastic bans, choosing environmentally friendly materials has become essential. It not only gives customers peace of mind but also helps businesses build a strong brand image.
