FAQ

What types of greenhouses and crops is the Sainpoly greenhouse plastic film (6/8/10/12 m) best suited for?

Sainpoly film is versatile and can be used on hobby hoop houses, walk‑in tunnels, single‑span and multi‑span commercial greenhouses, and nursery frames. It works well for vegetables, herbs, flowers, ornamentals, seedling propagation and many hydroponic systems — basically any crop that benefits from a clear, weather‑resistant covering and controlled microclimate.

How do I choose between the 6 m, 8 m, 10 m and 12 m widths?

Select the film width to match the greenhouse span plus overlap/seam allowance. Typical guidance: 6 m for small single‑span structures, 8 m for medium hobby or small commercial spans, and 10–12 m for larger single spans or gutter‑connected multi‑span houses. Always allow for the anchoring and seam overlap your framing method requires (commonly 20–50 cm per edge or more for welding/taping).

What are the recommended installation methods and tips for a secure, long‑lasting cover?

Unroll film along the frame, keep it clean and free of sharp edges, and tension it evenly to avoid flapping. Fasten with wiggle wire/aluminum profile or battens, and use hot‑air welding or UV‑resistant joining tape for seams. Leave a small allowance for thermal expansion, avoid over‑stretching, and trim edges carefully. Proper framing (rounded corners, no protruding bolts) extends life.

How should I maintain and clean the film to maximize its service life?

Wash periodically with mild soap and water to remove dust, algae and residues; avoid solvents or abrasive tools. Inspect after storms for tears and patch promptly with compatible repair tape or welding. Re‑tension if sagging occurs and store spare rolls or cuttings in a cool, dry place away from direct sunlight. Regular maintenance can preserve clarity and performance over multiple growing seasons.

Is this greenhouse film suitable for different climates (cold, hot, high‑UV) and does it provide insulation or UV protection?

Many Sainpoly films are UV‑stabilized and incorporate anti‑condensate or light‑diffusing options; these features improve durability and crop light distribution. For colder climates, using a double‑layer (inflated air gap) system markedly improves thermal retention. In very sunny/high‑UV regions, select a long‑life UV‑stabilized grade or add shade cloth in summer to protect crops and extend film life.

Can the film be used with heating, shading and automatic ventilation systems? Any compatibility concerns?

Yes — the film is compatible with heaters, exhaust fans, motorized vents and shading nets. Take care to keep the film away from direct contact with heat sources, open flames or hot pipes, and ensure fasteners and moving parts don’t abrade the material. If using automated systems, plan clearances and anchor points so the film can move or be retracted without being pinched or cut.
