Industrial paper cores are made from a mixture of recycled paper and wood pulp to create layers of paperboard that are wound into cylinders. Cores are made in various thicknesses and lengths, making it easy to customize tubes based on clients’ needs. They can be used to organize materials for transportation and other industrial processes. Here are some uses for industrial cores:
Construction Tubes
Paper cores can be used as construction tubes for pilings and concrete footings in place of metal cylinders. They serve as molds for pouring liquid concrete and provide support during curing. Construction tubes have weather-resistant plies on the inside and outside. The ply lining is water-resistant, strong, and lightweight. This makes them easy to transport to construction sites while allowing them to withstand concrete pouring and curing.
Film and Tape Label Cores
Industries use paper tubes to produce cores for winding films, foils, and tapes. The spiral winding process bonds multiple paper layers, creating a durable structure when external pressure is applied. This makes paper cores functional for coiling flexible materials into rolls during manufacturing.
Core thickness vary depending on the material being wound. Craft tape cores may need to be thinner than those used for packing tape. Film core surface qualities include ground, polished, and skived, which affect how strongly a material adheres to the core. Most manufacturers also offer convolute wound cores for bend resistance and spiral wound cores for crush resistance.
Mailing Tubes
Mailing tubes protect items during shipping and can withstand external pressures during transit. Mailing tubes can be cut or wound to a client’s desired length or thickness. Core diameters and wall thicknesses allow mailing tubes to support items of varying weight, from posters to curtain rods. Mailing tubes may have flat ends or rolling edges for easier sealing and handling. Many manufacturers customize mailing tubes with custom colors or printed designs to match your branding.
Converter Cores
Converter cores are used in many industries to provide internal support to wound materials. They may be used for receipt paper, sticker rolls, and tickets. These cores are often short and dense to support rolling flexible materials without causing damage or distortion.
Yarn Carriers
Paper cores support yarn winding and storage. Manufacturers can produce yarn carriers in conical and cylindrical shapes. Tapered paper tubes allow for smooth unwinding, minimizing yarn breakage and tangling. Conical shapes guide yarn off the carrier without snagging. The core’s soft surface helps prevent yarn abrasion and contamination.
Manufacturers may customize cylindrical paper tubes for different yarn types or machine compatibility. A paper core’s surface can be grooved or notched to prevent yarn from slipping. An embossed coating may help reduce tangling when unwinding yarn. Manufacturers can tailor core designs to precise tolerances for automatic and semi-automatic winding machines.
