Custom Size Cardboard Cores for Tapes represent the backbone of efficient tape dispensing systems across industries. These precision-engineered cylindrical cores serve as the structural foundation for adhesive tapes, masking tapes, packaging tapes, and specialty industrial tapes. Unlike generic off-the-shelf options, our custom cores are manufactured to exact specifications, ensuring perfect compatibility with dispensing equipment and optimal tape performance. Crafted from high-strength paperboard with spiral-wound construction, these cores balance durability with eco-friendliness. Available in an extensive range of inner diameters, wall thicknesses, and lengths, they provide tailored solutions for everything from small household tape rolls to large industrial tape dispensers, ensuring smooth unwinding and consistent performance throughout the product lifecycle.
Each core is produced with tight dimensional tolerances (±0.1mm) ensuring consistent performance across production runs. The spiral-wound construction creates uniform strength distribution throughout the core, preventing warping or collapse under tension. Advanced cutting technology ensures clean, burr-free edges that prevent tape damage during unwinding.
Constructed from high-density kraft paperboard with grammage ranging from 150-400g/m² depending on application requirements. Multiple plies of paper are bonded with water-based adhesives that create exceptional radial strength while maintaining recyclability. For heavy-duty applications, reinforced plies or specialty papers can be incorporated to handle higher tension forces.
Offering virtually unlimited size configurations with inner diameters ranging from 12.7mm to 287mm, wall thicknesses from 0.4mm to 15mm, and lengths up to 6000mm. This extensive range ensures perfect compatibility with specific tape widths, lengths, and dispensing equipment. Special features like notches, slots, or end caps can be incorporated for specialized applications.
Made from 100% recycled paperboard with FSC certification ensuring responsible sourcing. The cores are fully recyclable in standard paper recycling streams, closing the material loop in tape production and usage. Water-based adhesives and VOC-free treatments ensure environmental safety throughout the manufacturing process and product lifecycle.

The most common application, providing cores for all types of packaging tapes including acrylic, hot melt, and water-based adhesive tapes. Standard 76mm inner diameter cores fit most manual and automated packaging dispensers, ensuring smooth unwinding during high-volume packaging operations.
Precision cores for delicate masking tapes used in automotive, aerospace, and painting applications. The controlled unwinding tension prevents tape stretching or tearing, ensuring clean lines and professional results. Custom lengths minimize waste for specific project requirements.
Heavy-duty cores for industrial tapes including duct tape, electrical tape, filament tape, and double-sided tapes. Reinforced cores handle the higher tension requirements of industrial applications, preventing core collapse during automated dispensing in manufacturing environments.
Specialty cores for medical-grade tapes and cleanroom applications. Manufactured in controlled environments with food-safe adhesives, these cores meet strict hygiene standards while providing precise performance for sensitive applications.
Ultra-smooth cores for adhesive transfer tapes and thin film tapes used in electronics and graphic applications. The precision winding ensures uniform tape layers that prevent wrinkling or creasing of delicate materials.
The primary factors are the tape width, length, and intended dispensing method. Wider tapes and longer lengths generally require larger inner diameters (typically 76mm for industrial applications) to maintain structural integrity. Manual dispensers often use smaller cores (38mm), while automated systems typically require 76mm or larger cores. Our engineering team can recommend optimal dimensions based on your specific tape specifications and equipment.
Wall thickness directly impacts strength and durability. Standard 1-2mm walls work for light to medium duty tapes up to 50m length. Heavy-duty applications with longer tape lengths (100m+) or higher tension require 3-5mm walls to prevent core collapse. For very heavy tapes or automated high-speed dispensing, reinforced walls up to 15mm provide maximum stability and longevity.
Yes, we offer extensive customization including notches, slots, keyways, and flanged ends for specialized dispensing equipment. These features can be precisely engineered to interact with specific dispenser mechanisms, ensuring proper alignment and tension control. Minimum order quantities may apply for highly specialized designs.
Standard custom sizes typically have a lead time of 7-10 business days after artwork approval. Highly specialized designs or large diameter cores may require 14-21 business days. We maintain inventory of common sizes for faster turnaround, and offer expedited production options for urgent requirements with a 3-5 day lead time.
Our premium cardboard cores match or exceed plastic cores in most performance metrics while offering significant sustainability advantages. They provide 90% weight reduction compared to plastic cores, reducing shipping costs and carbon footprint. While plastic offers marginally better moisture resistance, our treated cardboard cores provide sufficient protection for most applications. At end-of-life, our cores are 100% recyclable through standard paper recycling, unlike plastic cores which often end up in landfills.
