High-speed PP strapping equipment PP strapping production line with PLC control system
DESCRIPTION OF PP STRAPPING EQUIPMENT:
PP strapping production line is a specialized equipment combination for producing polypropylene (PP) strapping. Through a series of continuous processes, it transforms PP raw materials into high-strength, flexible strapping products, which are widely used in logistics, packaging, building materials, fruit processing, and home appliances.
Core Equipment Components of a PP Strapping Production Line:
1. Extruder
Function: Heats and melts PP raw material (granular, with optional color masterbatch, fillers, etc.) to plasticize it, and continuously extrudes the melt through a rotating screw.
Screw: Screw diameter (selected according to capacity requirements, commonly 30mm), length-to-diameter ratio (generally 25:1-30:1 to ensure full plasticization of the raw material), heating power (segmented temperature control to adapt to the raw material's melt profile).
2. Die (Extrusion Die)
Function: Extrudes the melt conveyed by the extruder through a die of a specific shape (usually a flat slit) to form a preliminary strip-shaped billet (thickness and width must match subsequent processes).
Features: The die gap is finely adjustable to ensure uniform billet thickness; the internal flow channels are smooth, reducing melt resistance and preventing raw material degradation.

Introduction to the stretching process:
Core process: By using the speed difference between two or more sets of stretching rollers (the rear roller speed is higher than the front roller), the cooled billet is axially stretched (the stretching ratio is usually 3-8 times), causing the PP molecular chains to align in an oriented manner, significantly improving the longitudinal strength and toughness of the strapping.
Auxiliary conditions: Some production lines will install preheating rollers before stretching to heat the billet to above its glass transition temperature (approximately 80-120℃) to enhance the stretching effect.
