1. Current Status and Recycling Difficulties of LDPE Film Waste in Mexico

1.1 Main Sources and Waste Characteristics of Mexican LDPE Film

Mexico has a developed agricultural industry and active light industrial manufacturing and commodity circulation industries, forming a huge output of LDPE film waste every year. Agricultural LDPE mulch films are widely used in northern Mexico’s crop planting areas. After seasonal use, a large number of waste films are mixed with soil, crop residues, and fertilizer impurities, with extremely high dirt content. Industrial packaging LDPE films come from factory product packaging, logistics winding films, and warehouse protective films, mostly mixed with oil stains, dust, and adhesive residues. Civilian waste LDPE films are mainly shopping bags, food packaging films, and daily protective films, featuring complex material mixing and uneven thickness.

Different from European and American high-purity centralized waste materials, Mexican local LDPE film waste has obvious characteristics of high impurity, high moisture, high dirt and mixed materials. Most waste films are randomly recycled without classification, containing a small amount of HDPE impurities, paper scraps, and fiber sundries, which puts forward higher requirements for the impurity removal, cleaning and precise screening capabilities of recycling equipment.

1.2 Local Climate and Operational Challenges for LDPE Recycling

Most regions of Mexico have tropical and subtropical climates with high temperature and high humidity all year round. Waste LDPE films stacked in open air are prone to mildew, moisture absorption and microbial adhesion, further increasing the difficulty of cleaning and processing. In addition, the temperature difference between day and night in some northern regions is large, and the waste film will age and become brittle after long-term sun exposure, which is easy to produce fine debris during recycling and affects the yield of finished pellets. Traditional recycling lines lack targeted dehumidification, high-temperature cleaning and fine impurity removal functions for high-humidity and high-dirt materials, resulting in unqualified purity of recycled LDPE pellets, which cannot enter the high-quality downstream plastic product manufacturing market.

1.3 Industry Pain Points of Traditional LDPE Film Recycling in Mexico

At present, most small and medium-sized recycling enterprises in Mexico adopt traditional simple crushing and granulating equipment, which has many technical bottlenecks in actual production. First, the cleaning capacity is insufficient, unable to remove stubborn oil stains, soil and mildew impurities on the surface of waste films, resulting in dark color and many impurities of recycled pellets. Second, the melting and plasticization system is rough, prone to local overheating and material carbonization, producing a large number of black spots and defective materials. Third, the filtration precision is low, unable to filter tiny particle impurities, resulting in unstable tensile strength and poor uniformity of recycled pellets.

In addition, traditional equipment has low automation, requires a lot of manual sorting and auxiliary operation, high labor cost, low production efficiency, and no supporting wastewater recycling system. The production process produces a large amount of polluted wastewater, which does not meet Mexico’s local environmental protection emission standards, and enterprises face the risk of rectification and shutdown. The comprehensive profit margin of the project is low, restricting the standardized and large-scale development of local LDPE film recycling industry.

2. Core Advantages of POLYRETEC Austrian Technology Recycling Line

2.1 Inherited Austrian Industrial Precision Recycling Technology

3. Complete Process Flow of POLYRETEC LDPE Film Recycling Line

3.1 Raw Material Sorting and Automatic Feeding

Waste LDPE film raw materials collected from Mexico’s agricultural, industrial and civilian fields are firstly subjected to simple manual coarse sorting to remove large-size hard sundries and non-plastic impurities. Then the materials are sent to the automatic feeding machine, and the uniform and quantitative feeding system avoids material accumulation and blockage, ensuring stable and continuous feeding for subsequent processing. The closed feeding structure avoids dust overflow and keeps the production environment clean.

3.2 Anti-Winding High-Speed Crushing

The waste LDPE films enter the special LDPE soft film crusher. The optimized asymmetric cutter structure and anti-winding baffle design effectively solve the problem of winding and agglomeration of soft films during crushing. The equipment crushes the whole roll and whole piece of waste films into uniform flake materials of fixed size, which is convenient for subsequent full cleaning and impurity removal. The crushing particle size is uniform and adjustable, adapting to different film thickness and impurity conditions of Mexican waste materials.

3.3 Multi-Stage Circulating Friction Cleaning

This is the core process to solve the high dirt problem of Mexican LDPE waste films. The crushed film flakes enter the multi-stage circulating friction cleaning tank in sequence. Through high-speed water flow impact and material friction, the surface soil, dust, mildew and soluble impurities are fully removed. The high-pressure spraying device strengthens the cleaning effect on stubborn oil stains and adhesive residues. The multi-stage circulating water filtration system filters and precipitates impurities in the cleaning water in real time, realizing water recycling and reducing water resource consumption.

3.4 Fine Impurity Removal and Floating Washing

After preliminary cleaning, the film flakes enter the floating washing sorting tank. According to the different density characteristics of LDPE plastic and sundries, heavy impurities such as sand, stone and metal sink to the bottom and are automatically discharged, while light impurities such as paper scraps and fibers float on the water surface and are separated by the slag scraping device. This process effectively removes mixed heterogeneous impurities in Mexican mixed waste films and improves the purity of recycled raw materials.

3.5 High-Speed Dewatering and Constant Temperature Drying

The cleaned film flakes contain a lot of water, especially suitable for high-humidity materials in Mexico. The high-speed centrifugal dewatering machine firstly removes most of the surface moisture, and then the constant-temperature hot air drying system performs deep dehumidification treatment to ensure that the moisture content of the film flakes is controlled below 0.03%. Thoroughly solving the problem of bubble and hollow defects in recycled pellets caused by excessive moisture of raw materials, laying a foundation for high-quality pelletizing.

3.6 Low-Temperature Uniform Melting and Plasticization

The dried high-purity LDPE film flakes enter the high-torque single-screw extruder. Adopting Austrian graded low-temperature plasticization technology, the materials are fully melted and homogenized at a stable temperature, avoiding local overheating and material carbonization. The screw structure is optimized for LDPE low-density materials, ensuring uniform melt viscosity and stable internal molecular structure of the melt, and improving the toughness and gloss of finished pellets.

3.7 Multi-Layer High-Precision Melt Filtration

The molten LDPE melt passes through a multi-stage high-precision filter screen and automatic mesh changing system, which can intercept tiny particle impurities, carbonized points and residual sundries in the melt. The automatic mesh changing device realizes non-stop mesh replacement, avoiding production interruption and improving production continuity. The filtered melt is pure and uniform, without any impurity defects, ensuring the high purity and stable performance of recycled pellets.

3.8 Water Ring Cutting and Cooling Pelletizing

The purified LDPE melt is extruded through the die head and pelletized by high-speed water ring cutting. The circulating water cooling system rapidly cools the pellets to shape, ensuring uniform particle size, smooth surface and consistent density of finished pellets. The finished pellets are automatically screened and collected to remove fine powder and defective particles, and finally obtain high-quality LDPE recycled pellets that meet European and Mexican industrial standards.
