MG paper and kraft paper are two widely used paper-based packaging materials in global supply chains, but they are designed for very different performance requirements. One focuses on surface finish and printability, while the other emphasizes mechanical strength and durability.
Understanding the differences between them is important for packaging engineers, converters, and buyers selecting materials for food packaging, industrial wrapping, or retail applications.
MG paper (Machine Glazed paper) is produced through a specialized drying process where one side of the paper is pressed against a heated polished cylinder, creating a naturally glossy surface while the other side remains matte and fiber-textured.
According to product specifications from China Paper Company, MG paper is typically available in a basis weight range of 30–70gsm and is designed for flexible packaging applications such as food wrapping, retail packaging, and industrial light-use materials.
It is also commonly supplied in formats such as MG white paper and MG poster paper, depending on printing and packaging requirements.
Unlike fully coated paper, MG paper achieves gloss mechanically rather than through chemical coating, which helps preserve fiber flexibility while maintaining a printable surface.
Kraft paper is manufactured using the kraft pulping process, which chemically treats wood chips to preserve long cellulose fibers. This results in a strong, tear-resistant material that is widely used in industrial packaging systems.
Kraft paper can be produced in both bleached and unbleached forms, but natural brown kraft is the most common in packaging due to its higher fiber strength and lower processing cost.
In industrial applications, kraft liner paper is often used as a structural material in corrugated packaging systems and shipping cartons.
Compared with MG paper, kraft paper prioritizes structural strength over surface finish, making it more suitable for load-bearing and protective packaging.
Although both materials are based on wood fiber, their performance differences become clear when applied in packaging environments.
MG paper is optimized for surface appearance and printability, while kraft paper is designed for strength and resistance to tearing or deformation.
The difference can be summarized through real application behavior rather than theoretical properties. For example, MG paper performs well in wrapping bakery products or lightweight retail packaging where visual presentation matters. Kraft paper, however, is more commonly used in shipping bags, corrugated packaging, and industrial wrapping where mechanical strength is essential.

Kraft paper focuses on tensile strength and durability
MG paper is more suitable for lightweight packaging
Kraft paper is preferred for heavy-duty packaging systems
| Feature | MG Paper | Kraft Paper |
| Surface Texture | One-side glossy | Natural rough |
| Strength | Medium | High |
| Fiber Type | Wood pulp | Virgin kraft fiber |
| Printability | High | Medium |
| Main Purpose | Wrapping & retail packaging | Industrial & shipping packaging |
MG paper is widely used in applications where flexibility and appearance are more important than load-bearing strength. In many packaging systems, MG paper is selected for its ability to combine light weight with acceptable print quality.
Typical use cases include food wrapping, bakery packaging, and medical packaging where hygiene and surface cleanliness are important. In addition, mg white paper is often used in retail environments where packaging appearance contributes directly to product presentation.
Kraft paper is widely used in logistics, e-commerce, and industrial packaging due to its mechanical durability. It performs well under stress conditions such as stacking, transportation, and long-distance shipping.
Common applications include shopping bags, corrugated box liners, and protective wrapping layers in export packaging systems. Its strength makes it suitable for products that require protection against tearing, compression, or external pressure.
Sustainability is one of the main reasons both MG and kraft paper continue to grow in global packaging markets. MG paper supports lightweight packaging strategies that reduce material usage, while kraft paper supports recyclability and fiber reuse systems.
Across the global paper market, both materials are increasingly used to replace plastic-based packaging in food and retail sectors. At the manufacturing level, companies such as China Paper Company continue to supply both MG and kraft paper grades to meet growing demand for fiber-based packaging solutions.
The choice between MG paper and kraft paper depends mainly on the function of the packaging rather than cost alone. MG paper is more suitable when visual appearance and print quality are important, especially for food wrapping or retail packaging. Kraft paper is more appropriate when strength, durability, and protection are the primary requirements.
In many real-world applications, manufacturers often use both materials within the same supply chain depending on packaging layers and product requirements.
MG paper and kraft paper serve different but complementary roles in modern packaging systems. MG paper focuses on surface quality and lightweight applications, while kraft paper provides strength and structural reliability. Both remain essential materials in global packaging production, especially within fiber-based packaging systems driven by sustainability and performance needs.
1. What is MG paper used for?
MG paper is mainly used for food wrapping, bakery packaging, and lightweight retail packaging applications.
2. Is MG paper stronger than kraft paper?
No, kraft paper is generally stronger due to its virgin fiber structure and longer cellulose chains.
3. What does MG stand for in paper?
MG stands for Machine Glazed, referring to the manufacturing process that creates one glossy side.
4. Can kraft paper be used for food packaging?
Yes, kraft paper is widely used in food packaging, especially for dry goods and takeaway bags.
