PP strap making machine 5mm PP strapping production line PP Strap Extrusion Line

DESCRIPTION OF PP STRAP MAKING MACHINE:

100 Percent PP Recycled Material PP Strap Extrusion Line

PP strap making machine &PP strapping production line features a twin-screw extruder and a "sandwich" structure design; it is engineered for manufacturers requiring high-volume production of premium-quality polypropylene (PP) strapping and offers high output alongside full automation.
Utilizing twin-screw co-extrusion technology (sandwich structure) and PLC control, the line boasts a rated output of 80 to 600 kg per hour and produces strapping with widths ranging from 5 mm to 19 mm and thicknesses from 0.4 mm to 1.2 mm.
Each unit is driven by a variable-frequency motor and equipped with an intelligent temperature control system, ensuring energy efficiency, uniform plasticization, and consistent product quality. Key advantages include environmental friendliness, energy savings, and high productivity. The equipment meets CE certification standards and utilizes professional-grade 38CrMoALA screws, making it capable of meeting the demands of high-intensity packaging facilities for continuous, round-the-clock production.

CORE ADVANTAGES :

**1. High Extrusion Output & Doubled Production Efficiency**

The core extrusion system utilizes an optimized, energy-efficient long screw and a precision barrel structure. This ensures uniform plasticization and stable output, effectively resolving common issues found in traditional equipment, such as uneven discharge and low capacity. The production line operates at speeds of up to 100–300 m/min, with an hourly output far exceeding standard equipment. It supports the simultaneous production of single or multiple straps and ensures stable, continuous 24-hour operation, significantly boosting mass production capacity. Additionally, the system features an automatic screen changer that allows for screen replacement without stopping the machine; this minimizes downtime, maximizes overall efficiency, and perfectly meets the demands of large-scale batch production.

**2. Intelligent Automation & User-Friendly Operation**

The equipment is equipped with an integrated smart touchscreen control system, allowing centralized management of all line parameters via PLC and touchscreen. Features include one-touch startup, automatic speed adjustment, constant temperature control, and automatic winding. The fully automated operation significantly lowers the skill barrier for operators; novices can get up to speed with simple training, and a single production line requires only 1–2 operators, effectively reducing labor costs. The system includes automatic fault detection, anomaly alarms, and overload protection. It monitors core data—such as temperature, rotational speed, and output speed—in real-time to facilitate timely troubleshooting, reduce equipment failure and defect rates, and ensure a stable, orderly production process.

SPECIFICATION

Process flow of PP packing belt production line

① Feeding →② stirring →③ pre-drying →④ melting and measuring extrusion →⑤ embryo (belt embryo) cooling and forming →⑥ oven preheating →⑦ primary stretching →⑧ secondary stretching →⑨ embossening → ⑩oven tempering and setting →⑪ cooling →⑫ finished product winding

The main components of PP strapping equipment:

Feeder---- transfer PP raw materials into the machine.

Extruder----heat and melt the PP raw materials and extrude them into shape.

Molding mold---- make the molten PP belt embryo pass through the mold to form a strip.

Cooling water tank----cool the extruded PP belt embryo to ensure its shaping.

Tractor----pull out the cooled strapping belt to maintain a stable production speed.

Oven---- heat the strapping belt to improve its strength and toughness.

Embossing machine---- emboss the surface of the strapping belt to increase friction and prevent slipping.

Shaping oven----heat again, shape, and make the PP belt more standardized.

Reeler---- reel the strapping belt into rolls for easy storage and transportation.

PP strapping equipment is used to produce PP strapping or use PP strapping for strapping. It can be divided into two categories: production equipment and strapping equipment:

PP strapping production equipment:

Main components------ 

Usually composed of: screw feeder, extruder, cooling water tank, first tractor, stretching oven, embossing machine, shaping oven, flower collecting machine, etc.

Working principle-----

 The raw material enters the strong extruder through the feeding system, and the PP strap embryo is pressed out from the die after heating and melting, and the cooling water tank quickly cools and shapes the embryo.

The first tractor transports the PP strap embryo to the stretching oven for heating and stretching, and the second tractor transports it to the embossing machine for embossing. The embossed strapping is eliminated from the internal stress by the shaping oven, and then cooled and shaped again by the shaping water tank, and finally transported to the coiler by the third tractor for winding, completing the production of PP strapping.
