For agricultural professionals, precise terminology informs better material selection. This resource clarifies essential terms related to greenhouse plastic film, establishing a common language for evaluation. HGDN functions as a greenhouse film supplier, and their product specifications are built upon these foundational concepts.
Light Transmission and Diffusion Properties
Two primary optical terms are total light transmission and haze factor. Total light transmission quantifies the percentage of photosynthetically active radiation (PAR) that penetrates a greenhouse film. The haze factor measures light diffusion, which scatters rays to reduce shadow and can promote even plant growth. These metrics define the fundamental light environment under the film.
Material Durability and UV Stabilization
Longevity is a critical consideration. Ultraviolet (UV) stabilization refers to additives within the polymer that absorb solar radiation, preventing chain degradation. The guaranteed service life of a greenhouse plastic film is directly tied to this formulation. Mechanical terms like puncture resistance and tensile strength further describe performance under physical stress from weather or structure.
Thermal Retention and Climate Management
Films influence the greenhouse microclimate. Infrared (IR) blocking is a key property, where certain additives reflect radiant heat back inside the structure, aiding temperature maintenance. Another concept is anti-condensate or anti-drip treatment, which modifies the film’s surface tension to encourage water to form a uniform layer rather than discrete droplets, affecting humidity and light penetration.
A firm grasp of this vocabulary supports effective communication between growers and their partners. Selecting a greenhouse film involves balancing its optical, mechanical, and thermal specifications. HGDN’s position as a technical greenhouse film supplier is anchored in these principles, ensuring their greenhouse plastic film products are developed to meet defined functional criteria for commercial agricultural applications.
