Cardboard tube is one of the most widely used products in the packaging industry. These tubes are made using layers of paper and special glue. Their production process is different according to the required diameter and thickness. Cardboard tube production requires high skill in knowing the production and cutting machinery. Also, familiarity with chemicals and adhesives is also important in the production of quality cardboard tubes. In the rest of this article, you will get to know the types of cardboard tubes and their production methods and uses.
Cardboard tube or paper tube production process
As mentioned, we need two main materials to produce a cardboard tube. Layers of paper and special glue are the materials that, in combination with each other, create cardboard tubes or paper tubes . The layers of paper are passed through a protective layer containing glue with special machines and then glued by placing them on top of each other.
paper roll
The paper used to produce the cardboard tube has a high role in its strength and resistance. This type of paper is often the same type that is used for cardboard. These papers are transported in large rolls from the paper factories to the paper tube factory . Then in the manufacturing plant, prepare for the next steps.
Large rolls of paper for cardboard are made from pulp in a paper mill. Due to the low importance of color and other qualities of this paper compared to writing papers, the raw materials of their pulp are obtained from recycling boards and second-hand papers. As a result, cardboard factories sell their production waste, which includes cardboard and paper scraps, to paper factories. Finally, a continuous cycle of paper and cardboard production and related products is formed.
After transferring the large rolls of paper to the paper tube factory, special machines are used to convert them into small rolls. These devices generally have several blades. The blade spacing is adjusted to match the manufacturer’s desired width for smaller rolls. The layers of paper are transferred under the blades by passing over the rotating rods (shafts) and after cutting, they are wrapped around another shaft. This process occurs semi-automatically. Finally, small rolls of paper are prepared to enter the paper tube production machine.
Cardboard tube glue
As mentioned, special glue is needed to connect papers and make cardboard tubes. Depending on their policies, manufacturing plants use various adhesives for paper from various domestic and foreign brands. The important and common point among all types of glue for cardboard tubes is that they are water-soluble.
Emulsion and water-soluble silicate adhesives are the best types of adhesives for paper tube production. These adhesives greatly increase the strength and stability of the final product. The characteristics of this type of glue include high dry film strength and suitable adhesion for paper and cardboard layers. Quality types of paper tube production glue have no smell. High-quality adhesives easily combine with water to create the final product.
The glue used to produce cardboard tubes or bobbins can also be used to produce special cardboards. The important thing is that you must clean the cardboard production machine before the glue dries. Due to the water-soluble nature of the glue, it cannot be used in cases where there is direct contact with water or high humidity.
Cardboard tube uses
The use of cardboard for packaging goes back many years. This industrial product, which is made by combining paper and glue or paper pulp, has many applications in various forms. Paper tube is one of the most widely used forms of industrial cardboard, which has many industrial, packaging and even artistic applications. The following are among the most famous uses of cardboard tubes.
- Use in the paper factory to wrap all kinds of paper ( known as cardboard tube in the industry )
- In textile factories producing fabric and thread for wrapping the product
- Factories producing disposable tableware and plastic
- In the printing industry for printer ribbons, adhesive rings and even wrapping printed banners
- In health uses, such as wound adhesive toilet paper
- In artistic applications such as cardboard tube art packaging and even food packaging such as coffee
As you read in the article above, cardboard tubes are one of the most widely used industrial packaging tools. Their production process is apparently simple, but it is complicated and difficult. These pipes are produced with various dimensions and thicknesses. In order to buy them, you must consider your usage. Rahsam cardboard tube manufacturing company is one of the oldest players in this industry in Isfahan. This company can meet your needs for various uses, well and at high speed.
