3 Questions JPT gets asked all the time!

Our Customers interact with us on many different channels, whether its over the phone or on live chat.


Here are some of most common questions we get asked:


1 - Why are cardboard tubes important for rolls of Carpets?


Cardboard tubes are commonly used as carpet cores for several reasons:

  1. Structural Support: Cardboard tubes provide structural support for carpets, which can be rolled around them for storage or transportation. Without a sturdy core to support the carpet, it could sag or warp, making it difficult to handle and potentially damaging the carpet.

  2. Cost-Effective: Cardboard tubes are generally less expensive than other types of cores, such as plastic or metal. This makes them a cost-effective solution for manufacturers of carpets and other rolled materials.

  3. Recyclable: Cardboard tubes are made from a renewable resource and are fully recyclable, which makes them an eco-friendly choice for carpet manufacturers. This reduces the environmental impact of the production process and helps to conserve natural resources.

  4. Lightweight: Cardboard tubes are lightweight, which makes them easy to handle and transport. This reduces the amount of energy required to move them around, which can also help to reduce the carbon footprint of the production process.



Overall, cardboard tubes are an important component of carpet cores because they provide structural support, are cost-effective, recyclable, and lightweight. These qualities make them a popular choice for manufacturers of carpets and other rolled materials.


2 - What gives cardboard cores their strength?


Cardboard tubes derive their strength from several factors:

  1. Material Composition: Cardboard tubes are typically made from multiple layers of paper, often with different grades or thicknesses. The paper used in the outer layers is typically made from long fibers, which makes it more resistant to tearing and puncturing. The inner layers may be made from shorter fibers or recycled paper, which provides additional stiffness and compression strength.

  2. Spiral Winding: Cardboard tubes are often manufactured using a spiral winding process, where a continuous strip of paper is wrapped around a mandrel (a rotating cylinder) and glued together. The spiral winding creates a continuous seam along the length of the tube, which adds strength and rigidity.

  3. Structural Design: The design of the tube also contributes to its strength. The diameter, thickness, and number of layers of paper can be varied to optimize the strength and stiffness of the tube for a given application. In addition, the ends of the tube can be reinforced with additional layers of paper or plastic caps to provide additional support.

  4. Manufacturing Process: The manufacturing process also plays a role in the strength of the tube. The paper may be treated with adhesives, coatings, or laminations to improve its properties, such as moisture resistance, stiffness, or durability.





Overall, the combination of material composition, spiral winding, structural design, and manufacturing process all contribute to the strength of cardboard tubes. These factors are carefully balanced to create a tube that is strong, lightweight, and cost-effective.

3 - Can cardboard tubes be recycling?


Yes, cardboard tubes can be recycled. In fact, they are considered to be one of the most environmentally friendly types of packaging because they are made from a renewable resource, are biodegradable, and can be easily recycled.

Cardboard tubes are typically made from a combination of recycled and virgin fibres. The recycled fibres can come from a variety of sources, such as old corrugated containers, newspapers, or other paper products. The virgin fibres may come from sustainably managed forests or other sources.

To recycle cardboard tubes, they can be placed in recycling bins or taken to a local recycling centre. Once at the recycling centre, they are typically processed with other types of paper products. The tubes are pulped and the fibres are separated from any contaminants or non-recyclable materials, such as plastic caps or adhesives.

The separated fibres are then used to create new paper products, such as cardboard boxes, tissue paper, or other types of packaging. This process reduces the need for virgin materials and helps to conserve natural resources.


It is important to note that not all cardboard tubes are recyclable, particularly if they are contaminated with food, grease, or other substances that can contaminate the recycling process. To ensure that cardboard tubes can be recycled, it is important to keep them clean and dry before placing them in recycling bins.
