1.BOPP (Biaxially Oriented Polypropylene) jumbo rolls serve as the primary substrate material for manufacturing adhesive tapes, including packaging tapes, printed tapes, and specialty tapes. Produced from 100% virgin polypropylene resin, these master rolls undergo a precision stretching process to achieve superior mechanical properties. Available in widths ranging from 1,000mm to 2,500mm and thicknesses from 35μm to 60μm (±1.5μm tolerance), each roll features consistent quality for optimal converting performance. Corona treatment ensures surface tension ≥38 dynes/cm, guaranteeing excellent adhesive bonding.

2.With outstanding physical characteristics, our BOPP jumbo rolls deliver tensile strength ≥120N/mm² (MD) and ≥200N/mm² (TD), elongation at break of 80-120% (MD) and 40-70% (TD), and a modulus of elasticity between 1,800-2,200MPa. The film exhibits exceptional optical clarity, with ≥92% light transmission, ≤2.5% haze, and a yellowness index ≤3.0—ideal for high-transparency tape applications. Thermal stability is equally impressive, with heat shrinkage ≤5% (MD) and ≤3% (TD) at 150°C/5min, a Vicat softening point ≥150°C, and a functional temperature range of -20°C to +80°C.

3.Customization options include anti-static treatment, UV stabilization, and surface texturing for specialized applications. Each roll is securely packaged with moisture-proof wrapping and ISPM15-compliant wooden pallets for export. Quality assurance includes ISO 9001:2015 certification, full-width defect detection, and batch traceability with a Certificate of Analysis.

4.Optimized for high-speed slitting (300-800m/min), our BOPP jumbo rolls ensure efficient processing with recommended tension settings of 10-15N/mm². For storage, maintain conditions at 15-30°C and 40-60% relative humidity (12-month shelf life). Minimum order quantity is 10 rolls, with a lead time of 15-30 days. FOB/CIF terms are available, and we provide free samples, technical support, and converting process optimization.
