PP/PE film washing line systems are designed to efficiently recycle and process post-consumer polypropylene (PP) and polyethylene (PE) plastic films.

Optimizing a PP/PE film washing system’s process is a critical issue affecting the cleanliness, efficiency, and overall quality of film production.

The post-treatment process is the key to improving wastewater residuals in the cleaning process, the cycle time of a single wash, and improving film efficiency.

Washing equipment selection and configuration of PP/PE film washing systems.

The selection and configuration of washing equipment are critical to the overall PP/PE film-washing system. Proper equipment selection ensures that residual contaminants on the film surface are effectively reached while avoiding damage to the film.

Types d'équipement

  • Rinsing: Utilizes a water stream to rinse the film surface, removing Large impurities.

Equipment Configuration

  • Multi-stage cleaning: using different types of equipment to realize various types of Ethernet.
  • Recycling cleaning: Recycling the cleaning solution several times to reduce water and chemical consumption.


Optimization of post-treatment process parameters PP/PE film washing systems.

Optimizing post-treatment process parameters is critical to improving the overall PP/PE film-washing system. These parameters include temperature, time, concentration, and pressure.


  • The proper temperature will dissolve and reach a specific waist. Excessive temperatures may damage the waist or cause it to cure.


  • Adequate soaking time ensures complete dissolution of the electrolyte. Excessive soak time may result in film corrosion or electrolyte re-deposition.


  • The concentration of the cleaning solution should be adjusted to the type and quantity of Manhattan. Excessive concentration may damage the film or leave a residue.


  • Proper pressure can help remove film recalcitrance and minimize secondary contamination. Excessive pressure may damage the film or cause splashing of the cleaning solution.

Other Parameters

  • Spray Pattern: Selecting the proper spray pattern ensures uniform cleaning and removal of all film. Number of cycles: Multiple cycles ultimately help reach the bottleneck, but too many cycles may increase costs.


How to optimize reprocessing formulations and washing fluids

Optimization of post-treatment formulations and cleaning fluids is critical to improving the post-treatment process of PP/PE film washing systems. Customized formulations that meet specific film needs can significantly improve cleaning results and productivity. Here are some keys to optimizing post-treatment formulations and cleaning fluids:

Strategies for

  • Characterize film contamination: Identify the contaminants on the film, including organic, inorganic, particulate, or biological films.

Select the appropriate cleaning agent:

  • Choose a cleaning agent that can dissolve, neutralize, or disperse based on the contamination profile. For example, nonionic or anionic surfactants may be practical for organic contamination.

Adjust pH and concentration:

  • Adjust the pH and concentration of the reprocessing solution for different film materials and contamination types to optimize cleaning efficiency. For example, acidic solutions are often more effective for acetate films.

Optimize temperature and time:

  • Set the appropriate post-treatment temperature and time based on the nature of the contamination and the increased heat resistance of the film. Corresponding temperatures and holding times can achieve cleaning results, but the film’s thermal stability should also be considered.

Adding additives:

  • Adding additives to the post-treatment solution, such as the formation of surface tension reducers, wetting agents, or binders, can enhance the agent’s ability to clean and reduce scale and deposits.

Monitoring and Adjustment:

  • Regularly monitor the effectiveness of the treatment fluid and adjust formulations and parameters based on cleaning results, dyeing results, and film quality.

Optimizing post-treatment formulations and cleaning fluids involves careful consideration of several factors. By employing the above strategies, film cleanliness can be significantly improved, productivity increased, and good film condition and performance assured.

Automation and control of reprocessing systems

Automation and control of the post-treatment system are essential to optimize the post-treatment process of PP/PE film cleaning systems. A breakthrough in automation and control allows precise regulation of post-treatment parameters to ensure the stability and quality of the cleaning process.

Parameter Monitoring and Feedback Control:

  • The automation system continuously monitors critical post-treatment parameters such as temperature, pressure, flow rate, and cleaning fluid concentration. Deviations from these parameters automatically trigger a feedback control mechanism that adjusts system operation for optimal cleaning results.

Logging and Analysis:

  • The automation system logs relevant data from the reprocessing process, such as cleaning data, cleaning consumption, and system malfunctions. This data feeds the subsequent analysis and optimization by continuously starting the system.

Terminal Monitoring and Control:

  • Through a terminal monitoring system, engineers and operators can monitor the operating status of the reprocessing system at the terminal, perform troubleshooting and maintenance operations, and avoid unnecessary production interruptions.

A well-developed automation and control system dramatically improves the reprocessing process’s stability, repeatability, and efficiency, reducing operating costs, improving film quality, and ensuring continued productivity.


Fault monitoring and troubleshooting of after-treatment systems

Regularly monitoring your reprocessing system is essential to identify potential problems early and take preventive action. The following points can help you establish an effective monitoring mechanism:

Define Key Completion Indicators (KPIs):

  • Identify key metrics that reflect the overall completion of the system, such as contaminant consumption of cleaned membrane pieces, cleanup cycle time, and water consumption.

Establish Baseline Data:

  • Collect baseline performance data for the system under normal operating conditions for comparison and troubleshooting.


  • Regularly monitor key performance indicators and compare them to benchmark data to detect anomalies or deviations in the data record.

If monitoring results show that the system is back to normal, careful troubleshooting is required. The following steps can help you systematically find the root cause of the problem:

Review recent changes:

  • Look for any recent hardware, software, or process changes in the system that could be a potential cause of the problem.

Inspect equipment:

  • Carefully inspect the equipment for clogged or damaged, including filters, pumps, and tubing.

Analyze the cleaning solution:

  • Extract and analyze the cleaning solution to confirm that its concentration, pH, and conductivity are within specifications.

Evaluate the cleaning process:

  • Review the cleaning parameters and process flow, such as cleaning time, temperature, and number of rinses, to confirm their optimized settings.

Consulter un expert :

  • If you cannot troubleshoot independently, seek the manufacturer’s help or a technical expert who can provide professional advice and support.

Proactive monitoring and troubleshooting are vital to ensuring that your reprocessing system continues to operate effectively. Following these steps, you can identify problems early and take appropriate measures to maintain your system in optimal condition.
