Ⅰ. HDPE/LDPE Packaging Bags: Widely Used Plastic Materials
High-density polyethylene (HDPE) and low-density polyethylene (LDPE) are two common plastic materials widely used in packaging bag production due to their excellent properties.
HDPE packaging bags offer high strength, rigidity, and chemical resistance, making them ideal for shopping bags, garbage bags, and food packaging bags.
LDPE packaging bags are softer and more transparent, commonly used in cling film, plastic bags, and packaging films.
However, improper disposal of used HDPE/LDPE packaging bags can cause severe environmental pollution.
Therefore, recycling and reusing HDPE/LDPE packaging bags by converting them into renewable resources is of great significance in reducing white pollution and advancing the circular economy.
Ⅱ. ACERETECH: Customized Recycling and Pelletizing Solutions
As a leading enterprise in the field of plastic recycling and pelletizing, ACERETECH is committed to providing efficient, environmentally friendly, and intelligent customized solutions tailored to customer needs.
For the recycling and pelletizing of HDPE/LDPE packaging bags, ACERETECH has customized the following equipment configuration for its customers:
Belt feeder with metal detector: Effectively removes metal impurities from raw materials, protects downstream equipment, and enhances product purity.
Compacting bin: Densifies loose materials to improve feeding efficiency and melt uniformity.
Dust removal unit: Effectively removes dust and impurities from raw materials, improves the production environment, and ensures product quality.
Double-stage single-screw extruder (diameter 140mm): The two-stage design ensures thorough plasticization and homogeneous mixing. The first stage is responsible for plasticization and preliminary mixing, while the second stage performs homogenization and pressurization, significantly improving product quality.
Double vacuum degassing: Effectively removes moisture and volatiles from the melt, improving product quality and stability.
SCF self-cleaning filtration system and non-stop piston filter (double filtration): The SCF self-cleaning system enables online automatic screen cleaning to ensure uninterrupted production. The non-stop piston filter allows screen replacement without machine shutdown, further enhancing production efficiency.
Water-ring pelletizing: Adopts water-ring cooling and cutting technology to produce uniform, non-agglomerating pellets with improved quality.
Vibrating dewatering screen: Effectively removes surface moisture from pellets, improving drying efficiency.
Centrifugal dehydrator: Further removes surface moisture from pellets, enhancing product quality.
Weighing silo: Provides accurate measurement for convenient subsequent packaging and transportation.
Intelligent touchscreen control: Features a user-friendly human-machine interface with easy operation and full automation, improving production efficiency and process stability.
III. Advantages of ACERETECH Solutions
High efficiency: High degree of automation and production efficiency, capable of meeting large-scale production requirements.
Environmental protection: Advanced dust removal and filtration technologies effectively reduce pollutant emissions and comply with environmental regulations.
Intelligence: Intelligent control system enables automated production, improving efficiency and process stability.
