In the world of packaging, labels play a vital role. Whether it’s for product identification, branding, or providing essential information, labels are essential for businesses across a wide range of industries. However, behind every label is a critical component that helps ensure labels are easy to apply, store, and handle: the label core.
If you’ve ever ordered rolls of labels for your business or worked in the packaging industry, you may have come across the term “label cores” and wondered exactly what they are and why they are so important. In this article, we’ll take a deep dive into label cores, explaining what they are, how they are used, and when and why you need them for your packaging and labelling operations.
What Are Label Cores?
A label core is the cylindrical spool, typically made from cardboard, around which labels are wound during the manufacturing process. These cores come in various sizes and are essential for supporting the rolls of labels, ensuring that they can be easily unrolled and applied to products without tangling or becoming damaged. Think of the label core as the backbone of the entire label roll – it provides structure and keeps everything in place.
Label cores can be made from various materials, with cardboard being the most common due to its strength, sustainability, and cost-effectiveness. In some cases, plastic or metal cores are also used, especially in heavy-duty applications where extra durability is required.
The Role of Label Cores in Labelling Operations
Label cores serve several important functions in the labelling process. They help maintain the integrity of the labels, keep them organised, and ensure smooth and efficient application. Let’s explore the key roles of label cores:
1. Providing Support for the Labels
Label rolls are typically produced by winding large quantities of individual labels onto a core. Without the core, the labels would be impossible to store, transport, or apply. The core provides structural support, preventing the labels from getting damaged or tangled, which is crucial for maintaining the quality of the labels and ensuring that they remain in good condition until they are ready for use.
2. Ensuring Smooth Dispensing
Label cores help ensure that labels are dispensed smoothly during application. When labels are wound properly on a core, they are easy to unroll, which reduces the likelihood of wrinkles, creases, or damage to the labels. Smooth dispensing is especially important in high-speed applications like packaging lines, where efficiency and precision are key.
3. Simplifying Storage and Transport
Label cores also make it easier to store and transport labels. Since they are rolled onto the core, it’s easy to stack and store label rolls in an organised manner. In a warehouse or manufacturing environment, this organisation helps improve space efficiency and reduces the risk of labels being damaged during transport or storage.
4. Providing a Reusable Solution
Many label cores, particularly those made from cardboard, are reusable. After labels have been used, the core can be recycled or reused for new rolls of labels. This makes label cores an eco-friendly option, contributing to sustainability efforts in packaging and labelling operations.
When Do You Need Label Cores?
While label cores are essential for most label applications, there are some scenarios where they are particularly necessary. Below, we’ll take a look at when you absolutely need label cores in your operations.
1. For Efficient Labelling Operations
If your business relies on high-volume labelling, whether for products, packaging, or shipping, you’ll definitely need label cores. High-volume labelling involves continuous dispensing of labels, and a core ensures that the labels unroll smoothly without causing jams or slowdowns in your production line. A label core helps maintain the pace of production and reduces downtime caused by label-related issues.
2. For Consistency in Label Quality
If you’re using automated or semi-automated labelling machines, label cores are critical for ensuring that the labels remain aligned and apply correctly. The uniformity provided by the label core helps maintain consistent label placement, which is particularly important for products that require precise labelling (e.g., food packaging, pharmaceuticals, or cosmetics). A poor-quality or damaged label core can result in misalignment, damaged labels, or faulty application, which can negatively affect your brand’s presentation.
3. When You Need to Store or Ship Large Quantities of Labels
If your business needs to store or ship large quantities of labels, label cores will help keep everything organised and protected. Whether you’re ordering labels in bulk or preparing labels for distribution to multiple locations, label cores ensure that the rolls remain compact and undamaged during transport. They also help prevent labels from becoming unwound or tangled, making them easier to use when they arrive at their destination.
4. For Custom Labels or Specialised Printing Jobs
When it comes to custom labels or more specialised printing jobs, label cores are necessary to ensure that the labels remain intact and properly aligned during printing. This is particularly important for businesses that print their own labels in-house, as it’s essential that the labels are wound neatly on the core to ensure proper feeding through the printer.
5. When Sustainability Is a Priority
If your business is focused on sustainability and reducing waste, using recyclable or reusable label cores can help you meet your environmental goals. Many cardboard label cores are made from recycled materials and can be reused multiple times before being recycled themselves. By opting for eco-friendly label cores, you contribute to a more sustainable packaging and labelling process, which is a positive step for businesses aiming to reduce their carbon footprint.
Why Are Label Cores Important for Businesses?
Now that we understand when label cores are necessary, let’s explore why they are so important for businesses across different industries.

Cardboard forming tubes are a common yet often overlooked component in construction projects. Despite their simplicity, these cylindrical tubes play a critical role in creating structures that are safe, durable, and cost-effective. In this article, we will explore what cardboard forming tubes are, how they are made, and why they are such a valuable tool in construction, particularly in the UK.
What Are Cardboard Forming Tubes?
Cardboard forming tubes, often referred to as “concrete form tubes,” are large, hollow cylinders made from heavy-duty, spiral-wound cardboard. These tubes are typically used as temporary forms for pouring concrete, particularly in the construction of foundations, columns, and other vertical structures.
The tubes are designed to hold concrete in place while it sets, maintaining the required shape until the concrete has fully cured. Once the concrete is solid and ready for use, the cardboard tube is removed, leaving behind a clean, well-formed concrete structure. These tubes come in a variety of sizes and thicknesses, allowing them to be tailored to the specific needs of each project.
How Are Cardboard Forming Tubes Made?
Cardboard forming tubes are manufactured by spirally winding heavy kraft paper around a core to create a strong and durable tube. The paper is treated to ensure that it can withstand the weight and moisture from the wet concrete while still being lightweight enough to handle easily on-site.
The tubes are designed to be smooth on the inside, making it easier to remove once the concrete has set. Some tubes are also coated with a special material to reduce the adhesion of concrete to the tube, allowing for easier removal after curing.
Manufacturers produce these tubes in various diameters, lengths, and thicknesses to meet the diverse needs of the construction industry. Custom-made tubes can also be ordered for specific applications, ensuring that they fit the exact dimensions required for a particular project.
Why Are Cardboard Forming Tubes Used in Construction?
1. Cost-Effectiveness
One of the main reasons that cardboard forming tubes are so widely used in construction is their cost-effectiveness. Compared to other forms like metal or plastic, cardboard tubes are far cheaper to produce and purchase. This makes them an ideal choice for projects with tight budgets or those that need to keep costs low without compromising on quality.
2. Ease of Use
Cardboard tubes are lightweight and easy to handle, making them simpler to transport and set up on-site. They can be easily cut or shaped to fit the needs of the project, which speeds up the construction process. Unlike more rigid materials, they don’t require special equipment to install, making them accessible to construction teams of all sizes.
3. Environmental Benefits
In recent years, sustainability has become a major concern in the construction industry. Cardboard forming tubes are made from recyclable materials, which makes them a more eco-friendly option compared to plastic or metal alternatives. After use, the tubes can be recycled, which reduces waste and supports the growing trend toward sustainable construction practices.
4. Quality and Finish
When used properly, cardboard forming tubes create clean and smooth concrete surfaces. The inner surface of the tube helps ensure that the concrete has an even finish and that it sets in a uniform shape. Additionally, because the cardboard is designed to easily come off, it leaves behind a professional-looking, smooth concrete column or foundation.
5. Time Efficiency
Cardboard forming tubes speed up the construction process by offering a quick and easy way to pour concrete into a mould. Because these tubes are pre-made and readily available, there is little preparation or set-up required. This saves valuable time on-site, helping construction teams complete projects more efficiently.
Common Uses of Cardboard Forming Tubes in Construction
1. Concrete Columns
Cardboard forming tubes are primarily used for creating concrete columns. These tubes can form the mould for columns of all sizes, from small supports to large structural pillars. The tube holds the concrete in place as it sets and cures, allowing construction teams to create strong, uniform columns that support the overall structure.
2. Footings and Foundations
Another common use for cardboard forming tubes is in the creation of footings and foundations for buildings. Footings are essential for supporting the weight of a structure and ensuring its stability. By using cardboard tubes, construction teams can quickly and easily form the holes required for pouring concrete foundations, ensuring that the base of the building is level and secure.
3. Piers and Posts
Cardboard forming tubes are also frequently used for creating piers and posts for fencing, decking, and other outdoor structures. Whether it’s for a garden shed or a more complex decking structure, these tubes provide a fast, cost-effective way to pour concrete supports that will hold up under pressure.
4. Bridge and Structural Supports
In larger-scale projects, such as the construction of bridges, roads, and high-rise buildings, cardboard forming tubes are used to create supporting pillars that must bear a great deal of weight and pressure. These tubes ensure that the concrete sets perfectly, giving the structure the strength it needs to withstand the forces it will face.
How to Use Cardboard Forming Tubes Effectively
To ensure that cardboard forming tubes are used effectively in construction, there are a few important steps to follow:
Select the Right Size Tube: It’s crucial to choose the correct diameter and length for the tube. Make sure it fits the specific dimensions of the structure you’re building. Oversized or undersized tubes can cause issues with the structural integrity of the finished concrete.
Prepare the Site: Before using the tubes, ensure the site is level and properly prepared. For larger projects, you may need to secure the tube to the ground to prevent it from shifting during the pouring process.
Add Reinforcement: Depending on the size and requirements of the project, you may need to add reinforcement, such as rebar, to the concrete within the tube. This will strengthen the final structure and ensure that it can handle the necessary loads.
Pour the Concrete: Once the tube is in place and prepared, you can pour the concrete inside. Ensure that the concrete is evenly distributed to avoid air pockets or weak spots in the final structure.
Allow Proper Curing Time: After pouring the concrete, allow it to cure properly. Curing time can vary depending on weather conditions, but typically, it takes several days for concrete to set completely.
Remove the Tube: After the concrete has fully cured, the cardboard forming tube can be carefully removed. If a coating was applied to the tube to reduce adhesion, this process will be even easier.
Cardboard forming tubes are an essential tool in construction, offering a simple, affordable, and environmentally friendly way to create strong concrete structures. Whether you’re working on small-scale projects like decking posts or large-scale infrastructure such as bridges, these tubes provide an efficient solution for moulding concrete columns, footings, and other essential components.
Their ease of use, cost-effectiveness, and environmental benefits make them a popular choice in the UK construction industry. By understanding how to use them effectively, you can ensure your project runs smoothly and achieves the best possible results. So, the next time you see a concrete pillar or post, remember that cardboard forming tubes (maybe from Curran) played a key role in its creation!
