Two-color mulch film unit

The three-layer co-extrusion black and white mulch blow molding machine integrates multi-layer co-extrusion technology to produce mulch with a unique black and white design. It uses the three-layer structure to customize the performance, which has both durability and anti-aging advantages, and can also weed and adjust the temperature. The production is efficient and stable, the specifications are flexible and variable, the operation is intelligent and simple, and the maintenance is easy, which helps the production of agricultural film to reduce costs and increase efficiency.

Aspect Details
Function Specifically designed for producing two-color mulch films. These films typically have two distinct colors, often one side is black to suppress weed growth by blocking sunlight, and the other side is usually white or silver to reflect light, which helps in regulating soil temperature.
Components Extrusion System: Consists of multiple extruders, usually at least two, each responsible for melting and pushing out different colored plastic resins.
Die Head: Shapes the molten plastic into a flat film. It has a precise design to ensure the two colors are evenly distributed and combined to form a single, cohesive mulch film layer.
Cooling Unit: After extrusion, the hot film passes through a cooling system, which may use air or water cooling methods to rapidly solidify the plastic, setting its shape and properties.
Winding Unit: Rolls up the finished two-color mulch film neatly for easy storage, transportation, and later use in the field.
Materials Processed Commonly used plastics like polyethylene (PE), which is durable, flexible, and has good heat resistance. Different additives may also be incorporated to enhance properties such as UV resistance, to prolong the film’s lifespan under sunlight exposure.
Production Capacity Varies widely depending on the model. Smaller, more compact units may produce several tens of kilograms per hour, while larger, industrial-grade ones can churn out hundreds of kilograms per hour, meeting the demands of both small farms and large-scale agricultural operations.
Advantages Enhanced Weed Control: The black side effectively inhibits weed germination and growth.
Improved Temperature Management: The reflective side modulates soil temperature, beneficial for crop growth.
Cost-Effective: By combining two functions in one film, farmers can save on the cost of using separate single-color mulch films.
Limitations Recycling Complexity: Due to the two-color design and potential additives, recycling is more difficult compared to single-color films.
Initial Investment: High-quality two-color mulch film units can be relatively expensive, posing a barrier for small-scale farmers.

Product features:

Multi-layer co-extrusion advantage

Structure and performance customization: Using three-layer co-extrusion technology, raw materials with different characteristics can be extruded separately and accurately combined. The middle layer can be made of raw materials with good toughness and tensile strength to enhance the durability of the film; the inner and outer layers are added with anti-aging and anti-ultraviolet additives to form a clear division of labor structure. The film produced in this way is not only tough and not easy to break, but also can withstand outdoor light and temperature changes for a long time, and the service life can be extended.

Efficient use of materials: Compared with single-layer blow molding, three-layer co-extrusion technology makes the mixing and matching of materials more scientific, reducing material waste caused by a single material that cannot take into account multiple properties, reducing production costs while improving film quality.

Black and white design features

Weeding function: The white surface can reflect sunlight, increase the light intensity near the ground, and promote crop photosynthesis; the black surface covers the ground, blocking sunlight, inhibiting weed growth, reducing weeds and crops competing for nutrients, water and sunlight, and reducing the cost of human and chemical herbicides in the field.

Temperature regulation: The black part absorbs heat quickly and releases heat slowly when the temperature is low at night, which adjusts the temperature difference between day and night in the soil to a certain extent, which is conducive to crop growth; the white surface can reflect part of the heat in the high temperature in summer to avoid burning crop roots due to excessive soil temperature.

blow molding efficiency

High-speed and stable production: Advanced screw and extrusion system, with strong plasticizing ability and stable extrusion pressure, can achieve continuous and high-speed plastic film blow molding production. Equipped with a precise die, it can evenly distribute materials in different layers to ensure the uniform thickness of the plastic film, and the thin thickness tolerance can be controlled within a very small range to improve the product qualification rate.

Flexible adaptation to specifications: It can easily and quickly replace different specifications of die heads, wind rings and other components, quickly adjust the width, thickness and other parameters of the plastic film, and flexibly meet the diverse needs of different planting scenes and different farmers for black and white plastic film sizes.

Ease of operation and maintenance

Intelligent control: Equipped with an automated control system, the operator can precisely control various production parameters such as temperature, speed, and extrusion through the human-machine interaction interface, reducing the difficulty of operation and labor intensity of workers.

Easy maintenance: The structural design of the equipment is compact and reasonable, and the layout of key components is scientific. During daily maintenance, workers can easily access inspection and repair parts. Additionally, the modular design of the blow molding machine allows for quick disassembly and replacement of individual modules that malfunction, reducing equipment downtime for maintenance.

 

Application scenarios:

Two-color mulch film units have diverse applications in modern agriculture. In vegetable cultivation, the black side blocks sunlight, preventing weeds from sprouting and competing with crops for nutrients, while the white or silver side reflects light, warming the soil earlier in spring, enabling an earlier planting season for tomatoes, cucumbers, etc. For fruit orchards, it helps regulate soil temperature, reducing the risk of frost damage to young fruit trees. During hot summers, the reflective side keeps the root zone cooler. In flower beds, it not only controls weeds but also beautifies the area, as the two-color contrast looks neater. Small-scale farms find it a cost-effective solution, and large plantations rely on it for efficient, large-area coverage, streamlining land management.
