Paper cores are made by winding together layers of paper or paperboard sheet to form a robust, hollow, cylindrical shape. Manufacturers use thick cardboard to make cores for industries like fabric, electrical, and construction, while they use thinner and less durable paperboard for toilet paper or adhesive tapes. Here are some of the common uses of paper cores:
Film Cores
Paper cores are widely used in the film industry for varying purposes. They support films, foils, and other flexible materials, which are wound around them. Their stout and rigid structure allows for easier transportation and storage of flexible items. Cores can be tailor-made for film and audio tapes to meet the strength and dimension requirements for different types. Depending on your requirements, they may grind, polish, or skive their surface qualities to keep the film safe and secure.
Adhesive Tapes and Labels
Thinner and less durable paper cores are used for adhesive tape and labels. The tape is rolled outward, and the core’s surface is polished to enable the recordings to bind to it. Technicians apply plastic or epoxy polishing to improve handling and functionality. The cores allow you to unwind the tape or label easily. They also allow you to package the tape in varying sizes and forms, giving you versatility.
Fabric Cores
Paper cores are used in the clothing and floor coverings industry, especially for packaging and transportation. Textile industries process fiber-based materials like fibers, yarns, filaments, and threads. After processing, the fiber is then manufactured into clothing or floor coverings like carpets. After mass production, the fabrics are wrapped around the cores for easier transportation or storage. The core’s outer surface can be rough to grip the fabric better.
Mailing and Shipping Tubes
You can use paper mailing and shipping tubes as packaging and storage tubes for assorted documents. These documents include maps, posters, prints of artwork, original paintings, blueprints, and engineering/architectural plans. Paper mailing and shipping tubes allow you to safely transport fragile documents over long distances while maintaining their quality.
Paper Mill and Printing Industry
The paper/printing industry uses paper tubes to wind large rolls of paper or newsprint. The cores can be used to roll all types of paper, including fine paper, recycled paper, specialty paper, or even tissue mills. They provide stability and stop creasing during transportation and storage. The cores can be thinner for wrapping paper or thicker for bulk paper rolls.
Construction Tubes
Paper cores are used as temporary formwork for concrete pillars and columns. They incorporate rebars and mesh to provide temporary support during the pouring and setting of concrete in construction. They help the structure maintain the correct shape and alignment until it dries. These tubes contain plies both outside and inside, offering a high-strength, weather-resistant substitute to metals. Paper dowel sleeves create channels within cast concrete for running communication cables, electrical wiring, and plumbing.
Spools and Reels
Spools and reels are round, cylindrical objects on which flexible objects like wires, ropes, threads, yarn, and cables can be wound. They come in different sizes, depending on the need. Cables and electrical wiring can be placed on large spools for easy construction use. Thread and yarn come on smaller cords that help keep them from tangling while being used in sewing.
