In the competitive world of plastic recycling, effectively removing labels and contaminants from post-consumer films is critical to producing high-quality regrind and pellets. Labels—whether from supermarket cling film, handbags, or industrial packaging—pose significant challenges during the washing process. Standard washing equipment often falls short, leading to residual impurities that degrade material value.
ASG has engineered an advanced label separation system specifically for challenging materials like LLDPE wrapping films. This innovative technology, also known as a paper-plastic separation system, ensures thorough cleaning, maximizes efficiency, and supports higher profitability for recyclers and international traders.
The Challenge of Label Contamination in Film Recycling
Labels, price tags, and adhesive residues are common on post-consumer plastic films. These contaminants can reduce the quality of recycled material, leading to lower market prices and limited application use. Traditional washers may not fully dislodge or separate these materials, resulting in increased operational costs and wasted resources.
How ASG’s Label Separation System Works
ASG’s state-of-the-art label removal system integrates seamlessly into existing washing lines and operates through a sophisticated, multi-stage process:
1. Pre-Treatment: Crushing and Soaking
The film is initially crushed and soaked to loosen labels and adhesives. This pre-treatment phase prepares the material for efficient separation in subsequent stages.
2. High-Friction Separation
The heart of the system is the paper-plastic separator, which consists of dual drums equipped with bidirectional conveyors. Each drum operates for a customizable duration—typically 3 to 5 minutes—based on the contamination level.
During operation, a high-speed rotor generates intense friction and mechanical action. The film is propelled upward along the rotor, thrown against the chamber walls, and subjected to continuous, high-intensity kneading and impact. This vigorous action disintegrates labels into pulp while preserving the integrity of the plastic film.
3. Efficient Discharge and Collection
Once separated, the clean plastic film is discharged via a hydraulic valve for further washing and processing. The disintegrated pulp is channeled away for collection or disposal. The system boasts a separation efficiency of up to 99%, drastically reducing impurity levels and enhancing the quality of the final product.
