Why cardboard cores are present in so many industries ?
Spiral tubes & cores are made from continuous strips of cardboard and various types of adhesives.
What’s special about them is that spiral cores and tubes offer excellent dimensional tolerances and crush strength. Cardboard cores are ubiquitous and are found in every aspect of modern-day life.
They are produced for a myriad of industrial applications and consumer products and sometimes considered to be commodity products.
Cores designed for winding, transport and finishing
On a global basis, the majority of paper tubes are used in industrial winding operations. In these applications, immediately after being manufactured, either paper, film, or textile yarn is wound directly onto paper tubes. The paper tube helps the wound material develop a stable roll structure and enables transportation of the manufactured material to a converting operation. These tubes range from small to wind paper, plastic, aluminum, cloth, and yarn consumer products, to large industrial cores to wind rolls of printing paper, plastic film, textiles, and specialty metals. Such tubes are designed to be used in interior environments for winding, transportation, and finishing operations. Most tubes for industrial markets are structurally optimized and engineered products. This is achieved by selecting proper paperboard strength and stiffness, tube thickness, ply positioning in the wall, and adhesive type in the design process.
In a role of building material
The Japanese have always had a special interest in paper as a building material. Paper shoji screens and lanterns define the traditional Japanese house. Shigeru Ban is a pioneer of paper tube structures. He has come up with a building system based on cardboard tube columns. In the last decade Ban has designed recyclable and easy to mount cardboard houses as well as designing shelters for refugees and disaster victims. He was surprised at the strength of the paper and then began to use paper tubes as structural systems. Although Ban has become an icon for advocates of ‘green’ and ‘eco-friendly’ architecture. That paper as fragile, flammable and cheap material is also suitable for making real buildings seemed unthinkable, until recently.
Reasons to use paper and cardboard, as a construction material are because cardboard is made from recycled paper, and can be recycled too. Cardboard tubes, made of recycled paper, have stable qualities and are highly durable. Tubes as structural materials are much lighter than wood, let alone steel or concrete. This characteristic is one of the great advantages because we can build light weight buildings very easily. The risk of destroying the environment is quite small when obtaining the materials or disposing of surplus waste. Cardboard tubes are simple, yet powerful and beautiful.
Cardboard core as an alternative
It is necessary to note that some traditional construction methods do more harm than good. They are damaging our planet. Our ability to evolve beyond these systems is becoming increasingly necessary. If we learn to live with alternative production and construction systems, we could radically slow down the destruction of the planet and possibly reverse certain aspects of the deterioration. For centuries, buildings have been built from found materials such as rock, earth, reeds and logs. These finite resources are being exploited and alternatives need to be found. Many of alternative materials have similar properties to those of traditional materials. There is no reason why these materials cannot be used more widespread in the construction industry. In fact some of them had greater strengths and durabilities than traditional materials.
Various materials can also be used inside the paper tube, such as the use of safe aluminum foil paper, which will greatly improve the freshness and safety of foods. Custom cardboard packaging has become an innovative way of packaging a variety of products. Paper cylinder packaging is 60% cheaper than metal, wooden or plastic boxes.
