Paper tubes are also known as paper cores, paperboard tubes, paper cans, fiber drums with paper drum machine, fiber tubes, paper tubing, wound tubes, composite cans, coreboard tubes, and cardboard tubes. While widely used everywhere, the term "cardboard tube" is a misnomer. Cardboard consists of three kraft layers with the central layer corrugated.
II. Paper Tube Types and Shapes
Paper Tube and Core Types
While paper tubes, paper cores and related products are all made from wound plies of paper or paperboard. Paper tubes with paper tube cutting machine or cores can be constructed from one, two or many plies of brown kraft paper or paperboard.
The innermost layer or ply, the liner, and the outermost layer, the wrap, can consist of different materials (foil, film, etc.) or specialized paper. The specialized paper and materials can provide water resistance, graphics or labeling, or a specific color.
Paper tubes have thinner walls and are widely used as containers or packaging for products with paper packaging machine.
A paper core is essentially a heavy-walled paper tube. The much thicker wall of paper cores enables their use in winding webs or sheets of flexible material into rolls in converting operations.
Paper tube and core manufacturing is a paper converting process combining web slitting, web winding and lamination or adhesive bonding steps. Through multiple wraps or revolutions of one or more paper webs or ribbons around a steel mandrel, several layers or plies of paper or paperboard are laminated together around a steel mandrel to form rigid, high strength tubes or fiber cores with paper core making machine.
Spiral Paper Tube or Core Manufacturing
In the spiral paper tube or core manufacturing process with paper core machine, jumbo rolls of paper, paperboard, and lining materials are converted in a rotary slitting operation with paper slitting machine into narrower width ribbons. The paper ribbons are rewound into narrow rolls on rewinding stands.
