The overview of Kraft Paper Tube
Multi‑layer kraft paper tubes are high‑strength cylindrical packaging and industrial components made by spirally winding and laminating two or more plies of high‑grade kraft paper with eco‑friendly water‑based adhesive. They offer excellent rigidity, pressure resistance, and stability while remaining fully recyclable and biodegradable.
The material of the tube is normally 100% virgin or recycled kraft paper (70~95g/ m²or 120–400 g/m² per layer as customized). and with 2 ~4 ply or custom multi‑layer construction. The color is natural brown kraft with a smooth inner wall and a tight spiral texture visible externally, or maybe just two or three layers of kraft paper are glued together.
Typical Applications：
- Industrial winding cores (film, foil, tape, fabric, paper)
- Shipping tubes for posters, artwork, documents, blueprints
- Protective packaging for electronics, cosmetics, gifts, and candles
- Structural and support components in furniture, construction, and manufacturing
- Industrial and electrical insulation tubes
Key Performance Features of Kraft Paper Tube
● High mechanical strength
Multi‑layer lamination greatly improves radial compressive strength, side impact resistance, and load‑bearing capacity, preventing deformation or rupture during transport and stacking.
● Stable dimensions & good concentricity
Precise winding ensures consistent inner diameter (ID), outer diameter (OD), and wall thickness; ideal for winding cores, telescopic tubes, and precision packaging.
● Eco‑friendly & safe
Plastic‑free, recyclable, compostable, non‑toxic, and compliant with global green packaging standards.
● Good processability
Supports cutting, chamfering, crimping, printing, labeling, and surface coating (waterproof, oil‑resistant, matte, glossy).
● Lightweight & cost‑effective
Lighter than metal, plastic, or composite tubes while maintaining strength; lowers logistics and material costs.
