LDPE Film Washing Recycling Line

Designed with robust, industrial-grade components, this washing line reliably handles high contamination loads (up to 70–80% impurities) without clogging or excessive wear. Wear-resistant shredding and cutting units protect against damage from sand and debris, ensuring continuous operation even in demanding applications. The process is arranged in multiple washing stages – including pre-washing, cold and hot water washing, and intense friction scrubbing – so that each type of contaminant (from large grit to water-soluble residues) is effectively removed in turn.

With over a decade of expertise in plastic recycling machinery, Boxin has engineered this LDPE film recycling line for easy operation and maintenance. The entire line is automatically controlled, with interlocked modules that coordinate feeding, washing, and drying. This not only maximizes throughput but also ensures stable performance and operator safety. Additionally, a circulating water filtration system is used to minimize fresh water usage and maintain cleaning efficiency, making the process more eco-friendly and cost-effective.

After washing and drying in the line, the plastic film flakes come out clean and with moisture content under 5%. The dry, uniformly sized flakes can be fed directly into pelletizing extruders to produce granules, or they can be sold/used as-is for various plastic manufacturing. Production capacity is flexible (standard models from 300 kg/h up to 3000 kg/h), and each line can be customized to match your specific throughput and cleanliness requirements.

Differences in Film Types & Recommended Washing Configurations

Different types of plastic film waste require tailored washing processes. Heavily contaminated agricultural films demand a more intensive setup compared to relatively clean post-industrial scraps or tough PP woven bags. Below we outline the differences and recommended configurations for various film types:

(For mixed film waste streams, our engineers will combine elements of the above configurations to effectively handle the blend of materials and contamination levels.)

Common Bottlenecks and Optimization Suggestions

During actual operation, LDPE film washing lines often face a few common issues (especially when dealing with very dirty agricultural films). Below are some typical bottlenecks and our technical optimization recommendations:

(By addressing the above issues with engineering solutions, Boxin’s washing lines run more smoothly, with lower maintenance needs and consistently high output quality.)
