SHLS-TC Economic Vertical Slitting Machine
1. Product Overview & Core Positioning
The SHLS-TC economic Vertical Slitting Machine is a cost-effective vertical film slitting rewinder independently developed by Sanhui Machinery. Designed as an entry-level vertical slitter, it targets small & medium soft packaging converters engaged in plastic film processing. Balancing stable cutting performance and competitive investment cost, this model is widely used for slitting PET, BOPP, PVC, PE, composite film and aluminized metallized packaging film.
Compared with heavy-duty vertical slitter series SHLS-A and SHLS-B, SHLS-TC retains essential core configurations including shaftless hydraulic unwinding, laser positioning, servo tension control and EPC web guiding, while optimizing structural layout to control procurement budget, making it the preferred solution for newly established packaging factories.

2.6 High Precision EPC Photoelectric Web Guiding
Feature: Photoelectric EPC edge position correction system.
Advantage: Dynamic deviation correction during high-speed running.
Benefit: Correction accuracy reaches ±0.1mm, reduce raw material edge trimming loss.
2.7 High Running Speed up to 400 m/min
Feature: Maximum operating speed 0~400 m/min.
Advantage: Meet medium-volume continuous converting demands.
Benefit: Improve single-shift output and shorten delivery cycle for film orders.
2.8 Standard Slip Differential Air Rewinding Shaft
Feature: Standard 3-inch slip differential air expansion shaft.
Advantage: Independent tension control for each narrow finished roll.
Benefit: Solve uneven rewinding defects of thin and easily deformed plastic films.
2.9 Flexible Customization Support
Feature: Multiple optional upgrades and customized specifications.
Advantage: Match different material width, roll diameter and factory power standard.
Benefit: Avoid over-investment and configure machine according to actual production requirements.
3. Applicable Processing Materials
The vertical slitter adapts to various roll films widely used in flexible packaging industry:
- Polymer films: PET, BOPP, OPP, PE, PVC, CPP film
