I. ACERETECH ACSS Two-Stage Compacting & Pelletizing System: Enabling Efficient PE Film Recycling
As global demand for recycled plastics continues to rise, PE film recycling has emerged as one of the fastest-growing sectors in the plastics recycling industry. From packaging films and agricultural films to industrial production waste, polyethylene (PE) film generates vast quantities of recyclable material annually.
However, PE film is notoriously difficult to recycle efficiently due to its lightweight and flexible nature, high moisture content, and tendency to tangle in machinery.
To address these challenges, ACERETECH developed the ACSS two-stage compacting and pelletizing system. This intelligent recycling solution integrates compacting, plasticizing, filtration, degassing, and pelletizing into a single unit. The system ensures stable, continuous operation and produces high-quality recycled pellets suitable for a wide range of downstream applications.
II. Industry Context: The Importance of PE Film Recycling
Polyethylene (PE) film is widely used across industries such as food packaging, logistics, agriculture, construction, and consumer goods. With global regulations increasingly encouraging circular economy practices, many manufacturing sectors are shifting toward using recycled PE materials as a substitute for virgin plastics.
Compared to rigid plastics, PE film recycling presents several challenges:
Low bulk density leads to unstable feeding.
Films are prone to bridging or tangling around rotating components.
Moisture, printing inks, and volatile contaminants can compromise pellet quality.
Impurities can disrupt production and damage equipment.
Continuous production requires efficient filtration and degassing systems.
For recyclers, selecting a specialized PE film pelletizer is crucial for maximizing production efficiency and ensuring consistent pellet quality.
III. Raw Materials
This recycling solution is suitable for various polyethylene (PE) film materials, including:
Low-density polyethylene (LDPE) film
Linear low-density polyethylene (LLDPE) stretch film
High-density polyethylene (HDPE) film
Packaging film
Agricultural film
Industrial PE film scrap
In-house factory PE film scrap
Printed PE film
PE bags and flexible plastic films
Depending on the cleanliness of the material, the system can be integrated with a washing and drying line prior to the pelletizing stage.

Ease of maintenance
High operational reliability
V. Complete PE Film Pelletizing Process Flow
The ACSS system integrates multiple processing stages into a single continuous production line:
PE film → Belt conveyor with metal detection → 800L compactor → Primary extrusion → Vacuum degassing → Continuous piston-type melt filter → Secondary extrusion → Continuous piston-type melt filter → Water-ring pelletizing → Vibratory dewatering → Finished PE pellets
This integrated process minimizes material handling while maximizing production efficiency and pellet quality.
