Product Description
Production Process Overview
This PP strapping band production line operates through a sophisticated multi-stage process ensuring optimal material properties and product quality:
- Extrusion: Temperature control maintained between 250°C and 280°C for proper material melting
- Cooling: Immediate water cooling after extrusion to create isotactic polypropylene with optimal crystal structure
- Stretching: Single-stretch process in boiling water to enhance longitudinal strength and reduce elongation
- Embossing: Pattern application through embossed rollers for improved friction and aesthetic appeal
Complete Production Flow
Materials feeding → Extruder melt → Filter → Melt metering pump → Extrusion die → Hot water tank → Five pulling rollers → Stretching oven → Stretching rollers → Embossing → Annealing treatment oven and water tank → Three pulling rollers → Winders → Packing
