Paper tubes have become a trend of the global packaging industry with their low-cost, versatile, and eco-friendly features. Don’t look at a small paper can, it is very simple to look at. But in fact, the progress of making paper cans is complicated. Today, we will introduce that how to make a paper tube:
Step 1：Roll the tube
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. The package paper tube is usually 2 pieces or 3 pieces, so it is necessary to roll the relative size of the paper tube.
Step 2: Apply Adhesive and dry the tube
The next step is to apply adhesive to the paper rolls. Paper tubes can hold their form and remain intact due to the use of glue on the paper rolls.
Step 3: Cut the tube
The spiral wound paper tube is fed into the cutting unit to cut the paper tube to the height required by the customer. A rotary knife or saw will come out on the tube and cut it to the desired length. The length of the tube depends on the distance between the knives. If longer tubes are to be made, the spacing of the knives will need to be larger.
Step 4: Affixed printing paper
After the paper tube is cut, the printed coated paper needs to be attached to the paper tube.
Step 5: Combine the paper tube
The last step of the paper tube is to combine the outer tube and lid covered by printed paper with the inner core. You can also choose to use plastic plugs, metal caps, etc.
You will also appreciate the value-added secondary operations such as embossing, notching, slotting, slitting, and die-cutting windows. Paper cores may have notches cut into the ends of the tubes to facilitate winding and unwinding of converted film, tape, cloth, or other roll stock materials. Openings can be cut into the side of a paper tube container and then a plastic film applied on the inner diameter to provide a window for viewing the packaged goods inside. Embossing provides a raised pattern on the surface. Functional embossing or raised bumps on the surface of a paper core can allow web materials to better grip the core surface during winding.
