Agro films, also known as agricultural films, are polymeric coverings used to nurture and increase crops.
Polyethylene agro film
Polyethylene is the most used raw material in making agro film. Due to its resilience and low pricing, nylon plastic is well-known. Because of its high clarity and strength, polyethylene is perfect for greenhouse covering. It is a flexible nylon plastic, chemical resistant, and UV blockable. It can be transparent or opaque, depending on the coloring and thickness.
Polyvinyl chloride (PVC) film
A dexterous and hard plastic, PVC is good for low-cost greenhouses. It features a good strength-grade ratio. Its transparency can be readily modified by using various resin varieties. It has good chemical stability, although it does not remain as pliable as polyethylene during colder weather. It can be strengthened with additives for crop needs.
Polypropylene (PP) film
Polypropylene is a stiffer and more durable synthetic substance than polyethylene. It is also helpful for greenhouse applications due to its higher clarity. Because of its strength and adverse temperature, the nylon rope can be used in replacement panels and other sustainable systems. It is less typical than polyethylene and PVC due to a more costly cost.
Low-density polyethylene (LDPE)
Due to its flexibility and resilience, LDPE is often used in thin-film applications. In agro Films, it is commonly used to produce covering sheets and mulch films. LDPE is bendable, making it perfect for designs that need flexibility, such as crop covering and domes. In contrast to HDPE, it has lower molecular density, which causes it to be softer and thinner. Because of its effective light charge and thickness, LDPE is ideal for agro Film applications where short durability and lightweight are crucial.
High-density polyethylene (HDPE)
HDPE is produced from petroleum for several years and is well regarded for its strength, rigidity, and chemical resistance. Because of its high thickness, it is more robust and durable than other nylon rope types. Organic mulch is 1 common usage of HDPE in agriculture. When attached to soil, this film can kill weeds while permitting necessary water and nutrients to pass through for crop usage. Because of its sturdiness and durability, it can be utilized as a crop covering in shelters, which protects the vegetation from harsh weather conditions.
Climate Control
When properly installed on a structure, agro films can significantly improve crop yields. Pollutants are prevented from entering greenhouses due to climate control features in agro films. This procedure creates a growing environment that keeps the required amount of humidity, temperature, and sunlight for ideal plant growth. Climate control films aid in keeping cool in warm seasons and heating in cold growth. These films can feature color innovations and transparency that limit or let specific light spectrums to pass through.
Enhanced crop yields
The agro film acts like a super shield to help plants grow better. They increase crop productivity by more than 30% due to their climate control and UV protection features. Crops grow thicker and bigger when photosynthesis is well managed within the agricultural film. Additionally, these films shield plants from pests and disease and modify growing conditions to accommodate different crop types.
Cost-effective
Agro films are cheaper than other greenhouse regimes and structures. They are also lighter, which makes it easier and quicker to set them up, reducing labor costs. Also, they are reusable for many growing seasons.
Diffused light transmission
Some types of agro films are specially made to permit diffused light to pass through. The problem of uneven light distribution is solved by diffused light transmission, which typically leads to better photosynthesis and growth in crops. Light is made diffuse by the film's surface irregularities or internal structures. When done so, the light is reoriented rather than passing straight through, resulting in a soft, scattered illumination inside the greenhouse or on the crop bed. The plant's leaves can receive light from all angles thanks to this diffuse dispersal, enhancing its ability to absorb it.
Anti-drip features
Water droplets from the film's interior surface can land on vegetation, causing diseases or interfering with growth. Anti-drip film lowers condensation on the film surface by a thin layer of co-excipient nylon plastic to separate water molecules and prevent droplet formation. Droplets cling to the film surface rather than fall off and slide down it. This lowers the likelihood of disease transmission caused by excess water resting on leaves and facilitates better moisture equilibrium. Anti-drip films are especially useful in regions with wide temperature variations between day and night.
Greenhouse Type
The kind of agro film to be used will depend on the greenhouse type. Some films are more suitable for low-cost greenhouses than others. Polyethylene is usually strong enough for beginner and low-cost greenhouses. Users aiming for a more long-term and substantive greenhouse that provides good yields typically use polypropylene or treated polyethylene for better durability and clarity.
Film Thickness
Film density measures how long a film will survive and act. Thicker films usually give more strength and UV shielding, but they are heavier and have less light appeal. Thinner films are better in warmer regions or for temporary purposes because they are lighter. Farmers must consider the climate in their location and the kind of protection their crops need when deciding about film thickness.
Crop Requirements
The type of crops and their needs also affect the type of agro film to be used. Some films are better suited for specific crops. Clear films, for example, are ideal for heat-sensitive plants since they allow more solar energy to penetrate the greenhouse. Certain types of PVC or diffused films are suitable for tender shades that require lower light intensity.
Durability and lifespan
Certain agro films contain additives for prolonging life by absorbing UV and other light types that could damage them. PVC films are long-lasting but inflexible and prone to breakage in extreme weather. PE films, particularly treated ones, offer a good balance between clarity, adaptability, and robustness.
Budget considerations
The cost of these agro films will be affected by their durability, thickness, and material. PVC films are usually cheaper than others, but their adherence to properties is not good. Treated or thicker polyethylene may be more expensive but offers longer usage and a better shield. While some films are designed for temporary use, like one season, others are for long-term use with minimal replacement. There is a trade-off between short-term and long-term usefulness.
Greenhouses
The most popular use of agro films is in controlled conditions to allow year-round agriculture. These films help keep a steady temperature and light levels for optimum plant growth. Greenhouse vegetables, flowers, and tropical fruits that require specific climates thrive in this setting. Agro films help extend the growing season by keeping crops warm and promoting growth even in cooler months.
Mulching in field crops
Agro films are used for mulching to control weeds, conserve moisture, and regulate soil temperature in open fields. Mulch films are commonly used for tomatoes, peppers, melons, and other field crops to improve yields. Mulching with agro film gives efficient water usage by reducing evaporation and enabling irrigation. It prevents weeds from competing with the crops and protects fruits and vegetables from dirt and pests directly touching the ground.
Seedling nurseries
In nurseries, agro films cover seedling beds to boost germination and early growth. These films control humidity and temperature within beds, making sure seeds sprout and seedlings grow well. Nurseries producing young plants for later transplants benefit from using light-filtering films that shield the seedlings from harsh sun and keep the ideal moisture levels intact.
Pest control
Agro films play a key role in integrated pest management. Certain films, like insect netting or tunnel film, prevent pests from reaching the crops. This is suitable for fragile crops like cabbage, lettuce, and berries that are very sensitive to insect damage. In early spring or late fall, pest control films are often used to shield plants from harmful insects while maintaining ventilation and light exposure.
Tunnels and floating row covers
Agricultural films are designed to build tunnels or floating row covers that protect crops from extreme weather and insects. Tunnels made from agro films are used to keep heat in during cool nights and open days. They block pests while still letting water and air get through. These are widely used for tender crops like strawberries, grapes, and early greens that need extra frost and pest protection.
Hyper Care
Hyper care is an improved method of crop care that provides optimal conditions for achievement. These films help maintain the right temperature and moisture levels. Farmers growing high-value crops like orchids, Mediterranean herbs, and tropical plants employ agro films to provide the best growing conditions, boost quality, and increase market value.
