Paper tubes are used more and more widely, especially industrial paper tubes, which are widely used in papermaking, printing, plastic processing, metallurgy, food, packaging, decoration and other industries. Due to the advantages of low production cost, light weight, easy recovery and no pollution, paper tubes are used more and more.
Industrial paper tubes have excellent heat shrinkability, which can provide particularly tight packaging and fully reflect the true color of the packaging. At the same time, the industrial paper tube has excellent anti-static function.
In the production process of paper tubes, drying is an essential process. Proper process can save energy and ensure the quality of paper tubes.
In the process of producing paper tubes, the cylinder paper containing a certain amount of water is coated and rolled, so that the industrial paper tubes just rolled out during tube rolling are in a wet state, and the radial compressive strength is very low, which requires drying and evaporation of water. However, the newly rolled industrial paper tube is still in an unstable state. If it is dried immediately, the glue will remain between the paper layers and become a solidified substance. This will lead to loose adhesion of the paper layer and decrease of the radial compressive strength, so the paper tube and paper tube should be placed in the natural environment for about 1 hour before drying.
Industrial paper tubes can be made into various shapes and specifications according to actual needs, meeting the actual use needs of most industries.
