Wire Casing Tapes
Wire casing tape is a specialized functional trim designed to encase and secure underwire in intimate apparel, providing essential structure and comfort. Sewn to form a protective channel along the underwire placement, it prevents wire exposure, fabric abrasion, and discomfort while maintaining the bra's supportive framework. Available in woven construction with smooth, matte finishes, wire casing tape is engineered for durability and skin-friendliness in direct-contact applications. Our tapes come in precision widths that accommodate standard underwire gauges while ensuring clean, professional finishing. From classic nylon/elastane blends to specialized soft-touch formulations, we offer both stock and custom solutions tailored to your lingerie construction requirements and quality standards.
Wholesale Wire Casing Tape Manufacturer
As a vertically integrated wire casing tape manufacturer, our production process gives us complete control over every step—from yarn selection through weaving, dyeing, finishing and packaging. We use precision weaving equipment and rigorous quality-control systems to ensure each wire casing tape delivers consistent strength, smooth enclosure, and lasting comfort. Materials are engineered with tightly woven construction that prevents wire puncture while maintaining flexibility for body-conforming fit. Our finishing processes create soft, matte surfaces that eliminate irritation against skin. Our teams work closely with lingerie manufacturers to develop customized casing tapes that align with specific underwire dimensions, cup construction methods, and aesthetic requirements, ensuring both structural integrity and wearer comfort.

Top Questions About Our Wire Casing Tape
Wire casing tape width should match or slightly exceed your underwire diameter for proper enclosure:
● 3/8 inch (9.5mm): Standard lightweight underwires (8–9mm diameter) used in A-C cups and demi-cup designs
● 1/2 inch (12.8mm): Medium-weight underwires (10–12mm diameter) common in full-cup bras and D+ cup sizes
● Custom widths: Available for heavy-gauge wires in plus-size or specialty support bras
Proper width ensures the wire sits securely within the casing without excess fabric bulk while providing adequate protection against puncture. Too-narrow tape risks wire exposure; too-wide tape creates unnecessary bulk in the underwire channel.
Material composition balances durability with skin comfort. Nylon/elastane blends offer excellent puncture resistance through tight weave construction while maintaining flexibility for body-conforming fit. The nylon provides strength and abrasion resistance, while elastane adds controlled stretch for comfort during movement. Matte finishes eliminate shine and create soft hand-feel against skin. Higher thread counts increase puncture resistance for long-term wear, while softer yarn treatments enhance comfort. Premium formulations combine reinforced weaving for wire protection with brushed or specially finished surfaces for superior skin-friendliness.
Wire exposure prevention relies on several construction factors:
● Tight weave density: High thread count creates barrier against wire puncture
● Balanced tension: Proper fabric tension during weaving prevents weak spots
● Reinforced edges: Finished selvages prevent fraying and breakdown at fold lines
● Low stretch formulation: Minimal elastane content maintains dimensional stability around wire
● Quality stitching guidelines: Our technical specifications include recommended stitch types and seam allowances that distribute stress evenly
Additionally, proper attachment methods—including double-fold construction and reinforced stress points—ensure the casing maintains integrity throughout the garment's lifecycle. We provide detailed construction guidance to manufacturers for optimal wire encasement.
Yes, we offer comprehensive customization for both aesthetics and comfort. Our Pantone color matching service ensures casing tape blends seamlessly with cup fabric, wing materials, or lining colors for invisible finishing. For designs where casing is partially visible, contrasting or complementary colors can be developed. Softness customization includes brushed finishes, special yarn treatments, and cotton-backed constructions for enhanced skin comfort. We can also adjust fabric hand-feel from firm (for maximum support) to ultra-soft (for premium comfort) based on your target market and price point.
Our wire casing tapes are engineered for long-term performance in demanding intimate apparel applications:
● Colorfast dyeing: Industrial-grade dyes resist fading even with repeated washing and exposure to body oils and perspiration
● Dimensionally stable weaving: Pre-shrunk finishing eliminates post-wash distortion that could expose wires
● Abrasion-resistant fibers: Premium nylon withstands constant friction from wire movement and body contact
● Reinforced construction: High thread count maintains puncture resistance through hundreds of wear cycles
● Quality elastane: Maintains controlled stretch without becoming slack or losing shape
When constructed according to our technical guidelines, wire casing maintains structural integrity and wearer safety throughout the bra's expected lifespan, typically 6–12 months of regular wear and washing.
We offer several finishing treatments for enhanced comfort:
● Brushed finishes: Mechanical brushing creates soft, peach-skin texture that feels gentle against skin
● Silicon softening: Food-grade silicon treatment adds slip and reduces friction without affecting breathability
● Enzyme washing: Bio-polishing removes fiber protrusions for ultra-smooth surface
● Antimicrobial treatments: Optional treatments inhibit bacteria growth for freshness during extended wear
● Hypoallergenic formulations: Specially selected dyes and finishes minimize allergic reactions
All finishing options maintain OEKO-TEX certification and are safe for direct, prolonged skin contact. We can recommend optimal combinations based on your garment positioning and target customer sensitivity levels.
Yes, we manufacture reinforced wire casing tapes specifically for high-stress applications. These feature increased thread counts (up to 30% denser weaving), heavier-gauge nylon fibers, and minimal elastane for maximum dimensional stability. Reinforced options accommodate heavier underwire gauges common in D+ cup sizes and full-figure designs while maintaining smooth finish and comfort. We also offer wider widths that provide additional protection at high-tension points. Our engineering team can assess your specific underwire specifications and cup construction to recommend optimal reinforcement levels that balance support requirements with wearer comfort.
