Paper tubes are gaining traction in the global packaging industry. They have emerged as a low-cost, versatile, and eco-friendly packaging alternative that is being adopted by more and more industries in the world. The process of manufacturing paper tubes, types of paper tubes, and the benefits of using them for packaging are discussed below:
Step 1: Rolls of Paper
The first step in manufacturing paper tube packaging is to gather and process paper rolls. The manufacturing process for each manufacturer is specific to them. However, in a general process, large rolls of paper are hung and processed. The thicker the paper tube to be manufactured, the more rolls of paper are needed.
Step 2: Apply Adhesive
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. Glue is applied on each layer of paper and the excess glue is scraped off and pumped back into the system. This process of applying glue to paper rolls is known as a cascading gluing system. This is a very efficient system that applies just the right amount of glue on paper rolls and prevents wastage during the manufacturing process.
Step 3: Winding Process
Once the glue is applied on paper rolls, it is ready for further processing. The next process consists of winding the paper tubes. They are put on a winding machine. Different piles of papers are wrapped around a metal bar known as the mandrel. This step is known as winding. Paper tubes are rolled over the mandrel where they acquire their cylindrical shape. The belt in the winding machine pulls the paper rolls and ends a spirally wound paper tube. The entire process is automated and requires minimal human supervision and control. This makes it an efficient process for manufacturing paper tubes.
Step 4: Cutting the Paper Tube
The final step in manufacturing paper tubes is cutting them. Manufacturers use different equipment for cutting paper tubes. Some use knives while others use saw for the same. Spirally wound paper tubes are fed into the cutting unit. Rotary knives or saws will come out towards the tube and cut it to the desired length. The length of the paper tubes depends on the distance between the knives. If longer paper tubes have to be manufactured, then the knives need to be spaced more. Once the paper tubes are cut, they are packaged and sent to the customers. Some paper tubes go to other manufacturers while the others are sent to end consumers.
Type of Paper Tubes
The key different types of paper tubes used for packaging products are as follows:
As the name suggests, shipping tubes are used for transporting different types of products. Products can be packaged inside these paper tubes and are securely nestled between them. These paper tubes prevent any damage to the product during transit. They are very sturdy and can take blows, abrasions, dents, etc. without disintegrating. They are ideal for packaging delicate and breakable products.
These are made from high-quality paper and are used as postal tubes. They can take a lot of stress and wear and tear and protect the packaged product from any form of damage.
Why Use Paper Tube Packaging
Some of the most compelling reasons to use paper tube packaging are as follows:
Paper tube packaging is durable and provides good protection to the packaged product. It can protect the product from damage during transit and storage. Paper tubes also protect from external weather elements like wind, ultraviolet radiation, etc.
Businesses are becoming greener and more sustainable. They are focusing on sustainable packaging to make a better impact on customers. Paper tube packaging is completely degradable. They can be easily recycled which means they will not end up in landfills or ocean beds like plastic packaging. Manufacturing paper tubes are more eco-friendly than manufacturing plastics with the former accounting for only 1% of the global greenhouse emissions, compared to 3.8% contributed by the latter. This makes paper tube packaging better for the environment.
Another advantage of using paper tubes is that they are lightweight. You can transport more products with the same fuel. This further reduces the carbon footprint of paper tube packaging. You can easily stack paper tubes over one another. This makes it easier to store them during transit and in the warehouse. It can help you save storage costs.
Paper tubes are one of the cheapest materials for packaging products. They are much cheaper than plastic, metal, wood, etc. You can save a considerable amount of money on packaging costs that can boost your profit margins. You can also pass on the savings to your customers as reduced prices to gain a competitive advantage.
