Cardboard paper cores support rolled materials like foils, fabrics, and paper, helping to make goods easy to store and transport. These versatile tubes are made in manufacturing facilities by winding many layers of paperboard bound with adhesive. Here are some things paper cores are used for:
Paper Roll Storage and Transportation
Paper cores help store and transport paper rolls to protect product integrity. The end caps prevent materials from shifting during transport and make sure the materials arrive undamaged. Core features are specialized to different industries. Printing facilities need precise dimensions for equipment compatibility, and newspaper production requires extra-durable cores that can withstand high-speed printing press operations. Food packaging companies use cores with moisture barriers to protect contents, and thermal paper producers need cores with static-reducing properties to maintain print quality. Tissue manufacturers use smaller diameter cores for consumer products like toilet paper.
Textiles
Specialized cores are used in the textile industry for various applications. Manufacturers use reinforced cores with multiple layers of paperboard for heavier materials such as upholstery fabrics. These cores prevent the bending of the material, which could lead to creases. Specialty cores with polymer-based moisture barriers protect textiles from humidity damage during storage and shipping. For long-distance shipping, crush-resistant cores with increased wall thickness preserve sensitive fabrics during transit.
Shipping and Mailing
Cardboard tubes protect rolled documents from potential damage incurred during shipping by folding or tearing. Paintings and prints are shipped with acid-free mailing tubes to prevent deterioration from contact with standard paperboard. The tubes used by poster manufacturers to prevent content movement and edge damage include secure end caps so they don't shift. Different weight requirements are accommodated with thicknesses: thinner walls are used for lightweight documents, and thicker walls for heavier materials. Tube contents are protected from environmental factors such as humidity and water during transit with the help of specialized coatings as an additional barrier against damage.
Concrete Forms
Large-diameter cores are used as temporary structural molds for concrete columns in construction projects. These cores are water resistant, allowing the concrete to set correctly. The structural load requirements of the columns determine the cores that contractors choose, and these cores have different diameters. Extra-durable cores with reinforced construction work well for infrastructure projects that involve multiple uses over several concrete pours. Silicone release agents applied to the core exterior enable the core to be removed after the concrete is fully set without damage to the concrete structure or the form itself.
Film and Foil Support
Plastic films are wound onto cores for high-speed production lines. Specialized coatings and clean manufacturing processes ensure that cores meet strict FDA hygiene standards when used in food packaging operations. Film producers use cores with static reduction properties to prevent print defects or material cling. Industrial facilities use heavy-duty cores for insulation and vapor barriers that maintain structural integrity under the weight of heavy materials.
Get Tailored Paper Cores Solution
Modern cores are produced with sustainably sourced recycled materials, such as post-consumer paper waste. Printed branding, color coding, and specialized coatings can be used for specific applications. Proper core selection is significant and directly affects the integrity of the material wound around it. Contact professional core suppliers to find paper cores for your specific application needs.
