1. Light Transmittance & Uniformity 1.1 Transparency Standards Premium PO films achieve ≥93% light transmittance, outperforming conventional films by 20%. Key checks: ✅ Verify third-party test reports ✅ Request transmittance decay curves (e.g., ≥85% after 3 years) ❌ Avoid films with <90% transmittance 1.2 Uniformity Testing Conduct 9-point measurements with a professional lux meter: Test during sunny midday 3m×3m spacing between points Acceptable variance: <15%   2. Thermal Insulation Technology   2.1 Infrared Blocking Comparison Film Type Infrared Blocking Night Temp Control Standard PO ≤60% 3-5℃ Nano-Coated ≥85% 1-2℃ Composite 70-80% 2-3℃   2.2 Thickness Formula Ideal thickness (mm) = 0.08 + (Local Minimum Winter Temp / 10) Example: -20℃ regions → 0.10mm thickness 3. Anti-Dripping & Anti-Fogging   3.1 Performance Grades Grade A: Droplets slide off in <5 seconds Grade B: Droplets persist 5-15 seconds Grade C: High disease risk (droplets >15 seconds)   3.2 Quick Field Test Mist a 30cm×30cm sample Simulate greenhouse conditions with a heater  <10 minutes to clear fog     4. Anti-Aging & Durability   4.1 Essential Ingredients Must-have: HALS light stabilizers Avoid: Phthalate plasticizers (accelerate aging)   4.2 Lifespan by Environment Region Expected Lifespan Coastal High-Salt 1.5-2 years Northern Dry 3-4 years Southern Humid 2-3 years

High-quality films are essential for boosting crop yield and quality in today’s modern agricultural landscape. Infunplastic’s Blue Long-Life Drip Film is engineered with unique optical properties, superior drip functionality, and exceptional durability—making it the ideal choice for modern farming. 1. Enhanced Photosynthesis for Robust Crop Growth Our blue film offers a higher transmission rate for blue light, which plays a crucial role in photosynthesis, plant morphology, and phototropic responses. This enhanced light spectrum not only supports the synthesis of organic compounds but also effectively suppresses weed growth by reducing competition for water, nutrients, and sunlight, creating an optimal environment for healthy crops. 2. Superior Drip Functionality to Optimize the Growing Environment Utilizing advanced drip technology, the Blue Long-Life Drip Film quickly channels condensed moisture into droplets and efficiently directs them away from the film surface. This process lowers humidity levels inside the shed and minimizes the risk of disease and pest infestations, ensuring a stable, healthy microclimate for crop development. 3. Long-Lasting Durability to Lower Production Costs Infused with anti-ageing additives, our blue film is designed to withstand harsh weather conditions, resist UV radiation, and maintain excellent tensile strength. Its prolonged service life reduces the need for frequent replacements, thereby...
