Nowadays paper tube package is very common in retailing markets. Perhaps lots of us know the cylindrical packaging boxes are made of paperboard, kraft paper or cardboard. And some may already know how an industrial cardboard tube and core is produced.
Firstly: winding. Similar to industrial cardboard tube and cores, the majority are spiral-wound from multiple piles (layers) of paper or cardboard. According to specific packaging needs, paper of various types, tube molds and number of piles changes to obtain different diameters, thicknesses and strength. Thanks to gluing, layers of paperboard or cardboard are gathered, wrapped and formed into semi-finished.
Secondly, cut the semi-finished cardboard tubes into desired height (length) manually or automatically.
Thirdly, add the printed artwork (outer wrap paper) to the cut cardboard canisters manually or automatically. With this step done, the plain paperboard cylinder turns into a branded one.
Fourthly, take a second cutting to separate the whole branded tube into two smaller parts: top cap and outer base. Afterwards, one edge of both the top cap and outer base will be rolled (curled), followed by paper end closures being added. Now, the top cap is complete while the outer base not yet.
Finally, add the inner necks into the outer base by gluing.
When the final step is done, a cardboard cylinder is almost finished. After that, the workers will clean the cylinder containers for final QC inspection.
Above is a brief introduction to the production process of a three-piece paper tube packaging for retail applications.
