Welcome to Su Qian Huanyu Plastic Products Co., Ltd — a professional manufacturer with over 18 years of experience in producing high-quality agricultural plastic films. Our LDPE Black White film for Agricultural Silo Storage and Feed Preservation is designed to help farmers maximize feed quality and reduce spoilage. Combining a black inner layer that blocks light and a white outer layer that reflects solar radiation, this film creates an ideal anaerobic environment for silage fermentation. Whether you operate a small farm or a large commercial operation, our film offers reliable protection against oxygen, moisture, and UV damage.
Product Features & Benefits
Oxygen Barrier: Low oxygen permeability prevents mold growth and preserves nutrients, ensuring high-quality silage.
UV Stabilization: Resistant to prolonged sunlight exposure, extending the film's service life in outdoor applications.
Dual-Layer Design: White side reflects heat, keeping the silage cool; black side blocks light, inhibiting unwanted fermentation.
High Tear & Puncture Resistance: Withstands handling and soil pressure, reducing the risk of leaks.
Food-Grade Material: LDPE is safe for direct contact with animal feed, compliant with HACCP standards.
Customizable Dimensions: Available in various thicknesses, widths, and lengths to match your silo or bunker size.

Frequently Asked Questions (FAQ)
Q: What is the typical lifespan of your LDPE Black White film under direct sunlight?
A: With UV stabilization, the film can last 12-18 months in outdoor conditions. For longer storage, we recommend covering with a protective net or using our UV-enhanced variant.Q: Can this film be used for horizontal silos (bunkers) as well as tower silos?
A: Yes, it is suitable for all types of silage storage—bunkers, clamps, piles, and bags. The flexibility allows it to conform to different shapes.Q: Is the film available with custom printing (e.g., logo or instructions)?
A: Absolutely. We can print your brand name, usage guidelines, or other information on the white side using non-toxic inks. Please inquire for minimum order quantities.Q: How should I store the film before use to maintain its quality?
A: Keep the rolls in a cool, dry place away from direct sunlight and sharp objects. Store vertically on a pallet to avoid deformation. Use within 2 years of manufacture.Q: Do you offer samples? What is the shipping cost?
A: Yes, we provide free A4 samples (prepaid) for quality evaluation. For bulk orders, we ship FOB Shanghai/Qingdao. Our team will calculate the best freight option.Q: Is the film recyclable? Do you take back used film?
A: LDPE is 100% recyclable. We have a buy-back program for large volumes of used film (subject to terms). Alternatively, you can recycle it through local facilities.Q: What thickness do you recommend for corn silage compared to grass silage?
A: For corn silage (higher density), we recommend 0.12-0.15 mm. For grass or lucerne (more prone to damage), 0.15-0.20 mm provides extra puncture resistance.Q: Can you provide a certificate of analysis (COA) for each batch?
A: Yes, we provide COA including thickness, tensile strength, UV resistance, and food-grade compliance upon request. This is standard for ISO9001-compliant production.
