Introduction
Pre-stretch film rewinding machines are a key piece of equipment in the modern packaging industry, providing significant improvements in packaging efficiency and material utilisation by rewinding stretch film and applying pre-stretch force. With the increased need for environmental protection and cost control in logistics and manufacturing, this type of equipment has become an integral part of the global supply chain. In this article, we will discuss the working principle of pre-stretch film rewinders, their technical advantages and how to choose the right model, and combine domestic and international market data to provide you with a comprehensive decision-making reference.
The working principle and technical advantages of pre stretch film rewinding machine
Core Functions and Operation Flow
The pre stretch film rewinding machine achieves efficient rewinding through the following steps:
- Material input: loading of the original film roll onto the unwind spindle.
- Tension control: real-time adjustment of the tension force by means of sensors and servos.
- Pre-stretching treatment: mechanical or pneumatic devices are used to stretch the film to a pre-set percentage (usually 200%-300%).
- Precise rewinding: the winding shaft completes the roll at a constant speed, ensuring a homogeneous film layer without air bubbles.
Technical advantages compared to traditional equipment
- Energy saving and consumption reduction: pre-stretching technology reduces film usage by 30%-50%.
- Stability improvement: fully automatic stretch film winder can avoid manual operation error.
- Strong compatibility: support PE, PVC and other materials, suitable for Wintech stretch film machine and other brands of raw materials.
How to choose a suitable pre stretch film rewinding machine
Matching key parameters with industry needs
Need to pay attention when choosing equipment according to application scenarios:
- Production speed: the food industry usually requires models ≥50m/min.
- Tension range: Heavy goods packaging requires ≥200N tension control system.
- Customised function: If you need to be compatible with the recycled film output from plastic granulator, you need to choose customised stretch film winder.
