Types of Packaging Papers
Types of Packaging Papers: Kraft, Fluting, Testliner, and Liner
The packaging industry is one of the cornerstones of global trade and logistics. At its foundation lies packaging paper — the material that combines strength, functionality, and brand identity in every layer.
Among the different types, Kraft Paper, Fluting Paper, Testliner, and Liner Paper are the most widely used in corrugated board and packaging production.

Kraft Paper
Kraft Paper is one of the most common and durable types of packaging paper. It is made through the kraft (sulfate) process, which produces long, strong fibers with high resistance to tearing and moisture.
Key Features:
- Excellent mechanical strength
- Smooth surface suitable for printing
- Naturally brown color (also available in bleached white)
- Ideal for food, industrial, and protective packaging
Applications:
- Multi-layer bags and industrial sacks
- Food packaging and wrapping
- Outer layers in corrugated cartons
- Protective wrapping for shipping
Fluting Paper
Fluting Paper forms the middle corrugated layer of carton boards. It provides cushioning, rigidity, and vertical compression strength — vital for protecting goods during storage and transport.
Key Features:
- Flexible and strong under compression
- Produced mainly from recycled fiber (OCC)
- Easily shaped during corrugation
Applications:
- Middle layer in 3-ply and 5-ply corrugated boards
- Packaging for fragile or heavy products
Testliner Paper
Testliner is produced from recycled fibers and used as the outer surface layer of corrugated boards. It provides a cost-effective alternative to kraft liner while maintaining good appearance and strength.
Key Features:
- Smooth, printable surface
- Grammage range: 120–250 gsm
- Available in brown or white tones
Applications:
- Outer layer of corrugated cartons
- Branded packaging and export boxes
Liner Paper
Liner Paper is a surface paper used to cover or laminate corrugated or solid boards, improving appearance, print quality, and resistance. Two main types exist: Kraft Liner and Testliner.
Key Features:
- Resistant to humidity and crushing
- High printability (flexo or offset)
- Enhances visual quality of packaging
Applications:
- Outer and inner faces of corrugated boxes
- Packaging for consumer and export goods
Choosing the Right Packaging Paper
Selecting the correct paper depends on multiple factors:
- Product weight and sensitivity
- Transportation and storage conditions
- Branding and printing requirements
- Cost and recyclability considerations
Example combination for export cartons:
Kraft Liner + Fluting + Testliner — providing both aesthetic appeal and superior strength.
The Role of Chemical Raw Materials
In packaging paper production, the use of chemical additives such as starch, resins, and wet-strength agents plays a key role in improving quality.
These chemicals enhance bonding, moisture resistance, and fiber integrity, resulting in more durable and consistent papers used in corrugating and packaging lines.
