Low-cost agricultural tunnels

United Plastic Industries (UPI) is committed to providing high-quality products backed by a genuine guarantee that ensures customer satisfaction and continued performance, according to the type of product and the specified usage period.

United Plastic Industries (UPI) offers low-growing agricultural tunnel solutions made from polyethylene film, specifically designed to protect crops during their early growth stages and create a controlled microclimate around the plants. This contributes to a strong start to the season and improved production quality throughout the growing cycle.

Effective Row Covering:

This agricultural film is used to create low tunnels above rows of plants, acting as a protective cover that provides a more stable environment for seedlings and sensitive crops. Thanks to its carefully selected polyethylene composition and specialized additives, UPI tunnels help you:

Accelerate plant growth at the beginning of the season by raising the temperature around the plants compared to the outside air temperature.
Extend the growing period, allowing for early or late planting while maintaining plant vigor and quality.
Improve the growing environment for various types of vegetables, especially leafy greens and crops highly sensitive to weather fluctuations.
Maximize the use of cultivated space and reduce water loss compared to open-field farming.

Warranty

UPI reaffirms its commitment to providing reliable products backed by a warranty that enhances farmers’ confidence in product performance:

Warranty period: 12 months against any manufacturing defects.
The warranty covers maintaining the film’s essential properties—such as flexibility and shrinkage within permissible limits—when following the storage, installation, and operation instructions.

Technical Specifications

UPI's low-profile agricultural tunnel films are designed to suit short- and medium-term uses, taking into account the requirements of farmers in various agricultural environments.

Colours:

UPI low-profile tunneling films are produced in several basic colors to meet different lighting and thermal control requirements:

Clear
Green
White

Thicknesses:

Tunneling film is available in a range of thicknesses covering most low-profile tunneling applications, such as:

Thicknesses starting from 30 microns
Thicknesses starting from 100 microns.

Widths:

Displays starting from approximately 1.80 meters
Up to approximately 2.80 meters

Available Additives:

Tunnel films can be manufactured with one or more of the following technical additives – depending on the specific application:

To reduce the formation of water droplets suspended on the film’s inner surface, transforming it into a smooth layer. This minimizes the chance of water droplets falling on plants and reduces the spread of fungal diseases.
UV stabilizers to help maintain the film’s properties for longer periods under constant sunlight exposure.
Infrared control additives to reduce heat loss at night or limit daytime heat gain, thus improving temperature balance within the tunnel.
Light diffusers to help distribute light evenly within the tunnels and reduce harsh shadows on plants.
Special formulations to control certain light spectra associated with the spread of some viral diseases, supporting plant health within an integrated agricultural system.
