Description
This PET coated metal single binding wire is the workhorse of high-volume spiral notebook production — a continuous helical coil formed from Q195-grade galvanized steel and encapsulated in a PET (polyethylene terephthalate) polymer jacket. Within YPS's binding portfolio, single wire spiral represents the most cost-effective binding option, specifically suited to school notebooks, training manuals, pocket notebooks, and promotional runs where unit economics and production speed are decisive. The PET coating differentiates it from conventional nylon: while both are extruded onto pre-cleaned steel, PET delivers a harder, glossier surface with greater chemical stability, smoother feeding through high-speed forming machines, and better resistance to the solvents and oils that notebooks may encounter in industrial or food-service environments.
From a manufacturing standpoint, the PET coated metal single binding wire is supplied on continuous reels with tightly controlled tolerances. Standard diameters range from 0.7mm to 2.0mm with a tolerance of ±0.02mm, and coating thickness is typically held between 0.05mm and 0.07mm. Tensile strength is maintained in the 650–750 N/㎡ band for thinner gauges (0.7mm–1.05mm) and 580–680 N/㎡ for heavier diameters (1.1mm–2.0mm), ensuring uniform hardness along the entire reel — a prerequisite for consistent loop formation, stable pitch, and jam-free operation on Womako, Bielomatic, and Chinese forming machines. The smooth PET surface reduces friction against forming tooling, which extends consumable life and supports higher throughput on automated lines.
The single-wire format itself carries distinct engineering advantages. Pages rotate a full 360 degrees, and the notebook folds completely flat, making it the practical default for lay-flat reference materials and compact notebooks. Unlike twin-loop binding, single spiral requires only one continuous wire feed, simplifying machine setup and reducing changeover time on mixed-product schedules. For brands launching multiple SKUs with different page counts, this flexibility translates directly into shorter lead times and lower minimum run thresholds. The PET coated metal single binding wire is compatible with coil diameters from 6mm to 50mm and pitch options including 5, 6, 6.35, 8, 8.47, 10, and 12.7mm, accommodating everything from slim pocket journals to thick project binders.
Customization runs through the entire supply chain. YPS offers full OEM color matching on the PET jacket, with standard colors including black, white, red, blue, green, silver, and gold, plus custom Pantone references for brand-critical programs. The wire is supplied on spools in 400–450kg reels, and packaging can be specified for bulk industrial handling or converted into finished coils cut to common notebook formats. Because YPS operates as a vertically integrated manufacturer, coating extrusion, wire drawing, and coil forming occur under one quality system — meaning the PET jacket's adhesion, thickness, and surface finish are tuned not in isolation, but specifically for the forming behavior required downstream.
This PET coated metal single binding wire is not positioned for every application. Where maximum premium feel, extreme end-bend precision, or 100% rust-proof performance are the priority, nylon-coated double wire or R-PET plastic coils remain the better fit. But for high-volume school notebooks, budget-conscious promotional programs, and general-purpose spiral-bound documents where cost-per-unit and forming efficiency dominate the sourcing decision, PET-coated single wire is the pragmatic, reliable choice — backed by SGS test reports and consistent reel-to-reel quality that keeps automated binding lines running without interruption.
