Welcome to Su Qian Huanyu Plastic Products Co., Ltd. – a professional manufacturer established in 2006 with a factory spanning 3,000 – 5,000 m², an annual export value of US$1.5 – 2.5 million, and a dedicated team of 51 – 100 employees. Our Yellow Blown Polyethylene Greenhouse Film is specially engineered for multi-span greenhouses to provide maximum pest control while maintaining optimal growing conditions. By leveraging our HACCP and ISO9001 certified production lines, we deliver a film that not only repels harmful insects but also enhances light diffusion and thermal insulation – giving your crops a healthier, more productive environment.
Key Product Features & Benefits
- Pest Control through Color Technology – The distinct yellow color disrupts the visual orientation of common greenhouse pests such as whiteflies, aphids, and thrips. This reduces pest pressure without heavy reliance on chemical pesticides.
- Superior Mechanical Strength – Manufactured via advanced blown film extrusion, the film offers high tensile strength and tear resistance, capable of withstanding wind, snow loads, and mechanical installation stress.
- Optimized Light Transmission – The yellow tint selectively filters out certain wavelengths while allowing sufficient Photosynthetically Active Radiation (PAR) for crop growth. Light diffusion is improved, reducing shadows and promoting uniform plant development.
- UV Stabilization – Incorporated UV inhibitors ensure long-lasting performance under intense sunlight, preventing embrittlement and yellowing (the yellow color remains stable) for up to 3–5 years depending on thickness.
- Anti-Drip & Thermal Options – Optional anti-drip coating reduces condensation dripping, and thermal additives enhance night-time heat retention, suitable for multi-span structures.
- Customizable Specifications – Thickness from 0.08 mm to 0.20 mm, width up to 12 m, and length as per your requirements. We also offer custom printing and packaging.

Advantages for Multi-Span Greenhouses
Multi-span structures require large, continuous film covers that must balance strength, light management, and cost-effectiveness. Our yellow blown polyethylene film is specifically designed for these demands. The blown process ensures uniform thickness and fewer weak points compared to cast films. The yellow color acts as a physical barrier against pests by making the greenhouse less attractive to flying insects, thereby reducing the need for insecticides and lowering production costs. Combined with optional anti-fog and thermal layers, the film maintains a stable microclimate, reduces humidity-related diseases, and improves crop yield and quality.
Compared to clear films, yellow greenhouse film can significantly decrease whitefly populations – studies have shown reductions of 40–60% in infestations. When used in conjunction with other IPM (Integrated Pest Management) practices, it becomes a powerful tool for sustainable agriculture. Our product is already exported to North America, South America, Europe, Southeast Asia, Africa, Oceania, the Middle East, and other regions, proving its adaptability across different climates.

Frequently Asked Questions (FAQ)
- How does the yellow color control pests? – Many insects are attracted to specific wavelengths. The yellow film reflects light in a way that disorients pests like whiteflies and aphids, reducing their ability to locate host plants or enter the greenhouse through ventilation openings. It acts as a visual deterrent.
- What thickness should I choose for a multi-span greenhouse? – For typical multi-span structures, we recommend 0.12–0.15 mm for a balance of strength and cost. In harsh weather conditions (heavy snow, strong winds), 0.18–0.20 mm is advised. We can help you calculate based on your local climate.
- Is the film UV stabilized? How long does it last? – Yes, all our greenhouse films include UV stabilizers. Standard film lasts 3–4 years; with enhanced UV package, it can last up to 5 years under typical exposure. Actual lifespan depends on sunlight intensity and installation angle.
- Can I get the film with anti-drip coating? – Yes, we offer anti-drip (anti-condensation) coating on one side. This reduces dripping on crops and helps control humidity. Please specify when ordering.
- What certifications do you have? – Our factory is HACCP and ISO9001 certified. We also comply with international standards for food contact materials. For specific certification requests, we can provide additional documentation upon request.
- Do you provide samples? What is the minimum order quantity (MOQ)? – Yes, we offer free samples (shipping cost covered by client). MOQ is typically 1 ton per specification, but for new clients we can discuss smaller trial orders.
- How is the film packaged and shipped? – Film rolls are individually wrapped with anti-UV layer, then packed in cartons or pallets as per your requirement. We ship from Shanghai or Qingdao via sea, air, or express.
- Can the film be recycled? – Polyethylene is recyclable. We encourage customers to work with local recycling facilities. We also offer take-back programs for large volume orders in some regions – please inquire.
