As the "field guardian" of modern agricultural production, the efficient empowerment of plastic products not only comes from the precise matching of material performance and field scenes, but also relies on the deep integration of functional adaptability and green concepts. From weed-proof cloth to prevent weeds, to ground nails for fixed protection; from sunshade nets to provide shade and cooling, to mulch films to retain moisture and moisture—each product carries a unique operational function and agricultural mission. The gradient design of material thickness, precise adaptation of coverage area, and module upgrade of anti-aging technology give plastic products multiple application characteristics, allowing them to build a solid growth barrier for field crops and achieve precise management and protection in greenhouses. For farmers, choosing the right plastic product portfolio is not only an improvement in production efficiency, but also the practice of modern agriculture - they are like "invisible stewards" in the fields, transforming protection into a fruitful harvest.

Company introduction:

Shandong Shuangwei Plastic Industry Co., Ltd.'s business covers plastic manufacturing, hardware production, building materials sales and other fields, among which it is the core sector that promotes the green upgrading of the industry. The company's products include grass-proof cloth, mulch film, PVC double-wall corrugated pipes and supporting fixed ground nails. With the advantages of corrosion-resistant and anti-aging materials and accurately adapted specification design, they are widely used in various scenarios such as farmland irrigation, greenhouse management and protection, municipal drainage, construction projects, etc., providing integrated solutions for crop cultivation, water resources control, infrastructure construction and other aspects.

1. Agricultural grass-proof cloth series In the field of agricultural plastics, grass-proof cloth is a "growth barrier" for field crop management and protection. Take the company's 1.2m wide PE grass-proof cloth as an example. This product is specially designed for the growing needs of orchards, tea gardens and greenhouse crops. The traditional mulching film's weed control cycle is only 2-3 months, and it is easy to break and leave contaminated soil. The new weed control cloth is made of high-density polyethylene (added with anti-aging agents and anti-UV particles), with a thickness of 0.12mm, a tensile strength of ≥18kN/m, and the weed control cycle is extended to 3-5 years. In order to adapt to complex field scenes such as mountainous slopes, rainy and humid areas, the product has added two-way anti-slip texture and edge reinforcement hole design, which improves the stability of fixing with ground nails by 60% during laying, effectively preventing wind displacement. At the functional level, the grass-proof cloth integrates high air permeability (air permeability 200-300L/m²·24h) and water-impermeable soil properties, which can maintain stable soil moisture (fluctuation ≤5%), while inhibiting weed photosynthesis and reducing the frequency of manual weeding. This product has been widely used in Lanling Vegetable Base in Shandong. Compared with traditional mulch films, it reduces weed coverage in strawberry and blueberry orchards by 92% and reduces manual management and maintenance costs by 70%.     2. Matching floor nail series As the "fixed core" of plastic industry products, ground nails are a key accessory to ensure the stability of field applications such as grass-proof cloth and sunshade nets. The company's 50mm extended PE ground nails are specially designed for soft soil and windy areas. Traditional metal floor nails are prone to rust (with a service life of 1-2 years) and can easily scratch crop roots. However, the new floor nails are made of modified PP + glass fiber composite material, which is resistant to acid and alkali corrosion (can withstand soil environments with a pH value of 3-11) and has a service life of more than 5 years. The material is soft and has no sharp edges to avoid damage to crop roots. In order to adapt to grass-proof cloth and sunshade nets of different thicknesses, the top of the ground nails is designed with a "barbed disc" structure (diameter 30mm), which can firmly fasten the cloth surface when fixed. The pull-out resistance is ≥80N, and it can still remain stable in a level 8 wind environment. Taking a 10-acre grape greenhouse as an example, about 300 ground nails are needed per acre. The weight of this product is only 1/3 of metal ground nails. The transportation and laying efficiency is increased by 50%. It can be recycled and degraded after being discarded, which meets the requirements of green agricultural development. At present, supporting grass-proof cloth products have been promoted in Henan, Hebei and other places, helping farmers reduce the cost of replacement parts by 80%.

3. Agricultural mulch film and PVC double-wall corrugated pipe series​ In the field of agricultural and engineering plastics, mulch films and PVC double-wall corrugated pipes are key products covering the entire "crop cultivation-infrastructure" scenario. The company's 1.0m wide, highly translucent mulch film is specially designed for greenhouse seedlings and early growth of field crops. The light transmittance of traditional mulch film is about 75%, and it is easy to be brittle in low-temperature environments. The new mulch film adopts a three-layer co-extrusion process (inner insulation layer + middle weather-resistant layer + outer anti-slip layer). The light transmittance is increased to 92%, which can increase the soil temperature by 3-5°C. At the same time, the low-temperature resistance performance is optimized (no brittleness at -15°C), and the service life is extended to 6 months. In order to adapt to the needs of different crops, the mulch film thickness is available in two specifications: 0.08mm (vegetable seedlings) and 0.1mm (field crops), and a 5cm soil-pressing edge is reserved on the edge. After laying, the wind resistance displacement rate is reduced by 50%.​ PVC double-wall corrugated pipe is the core product of the engineering plastic industry. The company mainly promotes the DN300-DN800 specification series, which is designed for municipal drainage and farmland irrigation scenarios. Traditional concrete pipes are heavy (DN500 specifications weigh about 80kg per meter) and require large equipment for installation. Double-wall corrugated pipes are made of high-strength PVC resin (with impact modifier added), have a ring stiffness of SN8, weigh only 32kg per meter, and can be installed manually. The inner wall of the product is smooth (friction coefficient 0.01), the water flow capacity is 30% higher than that of concrete pipes of the same specification, and it has excellent corrosion resistance (can withstand liquids with a pH value of 2-12). It is suitable for saline-alkali land irrigation and industrial wastewater discharge scenarios. At present, this series of products has been applied in farmland water conservancy projects in Shandong, Henan and other places. Compared with traditional pipelines, the installation efficiency is increased by 60%, the comprehensive construction cost is reduced by 40%, and no anti-corrosion maintenance is required in the later period, and the service life is up to 50 years.​ It can be seen from these product cases that the plastic industry is currently moving towardsGreen, functional and scene-baseddirection development. Advances in material technology, such as the application of biodegradable resins and recycled environmentally friendly materials in products, have effectively solved the "white pollution" problem of the traditional plastic industry; continuous innovation in production processes, and the popularization of technologies such as three-layer co-extrusion and spiral winding molding, have achieved dual improvements in product performance and environmental protection attributes; customized design is integrated into the entire product process to provide precise specifications and functional solutions (such as anti-aging mulch films, high-strength corrugated pipes) based on the needs of different scenarios such as farmland, municipal administration, and construction. In the future, as modern agriculture's demand for "plastic reduction and efficiency improvement" escalates, and new infrastructure promotes the application of environmentally friendly building materials, the plastics industry is expected to open up a broader market space driven by material innovation and scene adaptation.
