PP sheets are highly practical in modern agriculture, as their properties fit agricultural production’s harsh and diverse conditions (extreme weather, frequent contact with water/fertilizers, and demand for durability with low maintenance).
Their key advantages include strong weather resistance: unlike wood or metal, they tolerate long-term exposure to sunlight, rain, frost, and temperature changes without degrading. UV-stabilized PP resists photodegradation, maintaining structure and strength for years, avoiding wood’s brittleness/rotting or metal’s rusting. They also have excellent chemical resistance—being inert to most agricultural chemicals (fertilizers, pesticides, herbicides) and not leaching harmful additives, thus preventing crop contamination and protecting soil ecosystems, which supports sustainable farming.
Additionally, PP sheets have near-zero water absorption (<0.01%), repelling water to avoid swelling, warping, or mold in humid areas like greenhouses. They are easy to clean, with dirt/residues washable via water or mild detergents. Lightweight yet rigid, they are lighter than wood, metal, or concrete, simplifying transportation, installation, and handling (no heavy machinery needed, cutting labor/time costs) while offering good impact resistance against farm equipment collisions or minor stress, ensuring long-term use.
These advantages enable various agricultural uses. In greenhouses, they serve as covering materials (adjustable 70–90% light transmittance, good insulation) to stabilize internal temperature for cold-season crop growth; shatterproof and lightweight, they reduce hail/wind damage and ease frame load. They also line greenhouse floors/raised beds to block soil moisture from harming frames and suppress weeds, lessening herbicide use.
In irrigation/water management, PP makes drip tape/pipe liners (chemical resistance prevents corrosion from irrigation water’s fertilizers/chemicals, smooth surface avoids sediment clogging) and large water tanks/pond liners (water-tight, non-porous, leak-proof, and algae-resistant). As mulch films for crops like tomatoes, they block sunlight to suppress weeds, retain soil moisture (reducing irrigation), and warm soil in early spring to speed seed germination and crop maturity, with no negative interaction with soil nutrients or beneficial organisms.
Moreover, PP sheets make seedling trays (lightweight for transport, water-resistant to avoid warping, reusable) and protective structures—windbreaks/frost covers (reducing wind damage and shielding plants from frost) and fencing for small animal enclosures (secure, weather-resistant, easy to clean for hygiene).
Overall, PP sheets solve traditional materials’ flaws (no frequent replacement, no contamination risks, lower labor/maintenance costs). Versatile, durable, and recyclable, they are sustainable for modern agriculture, boosting efficient, high-yield crop production with minimal environmental impact, and their use is expected to grow as agriculture prioritizes sustainability and cost-effectiveness.
