company news about Choosing the Right Thickness and Type for Plastic Greenhouse

The selection of plastic greenhouse film thickness (150μm vs 200μm) and type (high-transparency film, diffused film, etc.) hinges on matching local climate conditions, crop requirements, and expected service life. Given the significant variations in light intensity, wind force, precipitation, and UV radiation across different regions, targeted decisions are essential. Below is a detailed guide:

I. Film Thickness: 150μm vs 200μm? Consider Climate and Service Life
Film thickness directly affects durability, tear resistance, and insulation. The key differences and applicable scenarios between the two are as follows:
Aspect--150μm Film--200μm Film
Durability--Typically 3-5 years (temperate regions); may shorten to 2-3 years in tropical/strong UV areas--5-7 years (temperate regions); 4-5 years in tropical/strong UV areas
Wind/Tear Resistance--Suitable for areas with wind force ≤8 levels and moderate precipitation (e.g., Western Europe, Central North America) --Suitable for areas with wind force 8-10 levels and frequent heavy rain/hail (e.g., Southeast Asia, Northern South America)
Insulation--Moderate, ideal for regions with small day-night temperature differences--Superior (increased thickness reduces thermal conductivity), suitable for areas with large day-night temperature differences or cold climates (e.g., Mediterranean coast in winter, Central Asia)
Cost--Lower (15%-20% cheaper than 200μm) --Higher, but lower long-term replacement costs

Three Core Bases for New Buyers to Choose Thickness:
Local Climate Intensity:
Tropical/typhoon-prone areas (e.g., Philippines, Bangladesh) and regions with frequent heavy rain/hail (e.g., Northern India): Prioritize 200μm films for better impact and tear resistance, reducing the hassle of frequent replacements after typhoons.
Temperate/mild climate areas (e.g., Southern France, California, USA): 150μm films are sufficient, offering better cost-effectiveness and easier installation due to lighter weight.
High-altitude/strong UV areas (e.g., Mexican Plateau, East Africa): 200μm films are more resistant to UV aging (thicker films have more uniform distribution of anti-UV additives), extending service life.
Service Life:
Short-term cultivation (1-3 years, e.g., seasonal vegetables): 150μm films suffice to lower initial investment.
Long-term operation (5+ years, e.g., perennial fruits and vegetables): 200μm films are more cost-effective, reducing the labor costs of film replacement every 3-5 years (international labor costs are high; in Europe and America, labor costs for film replacement account for over 30% of the film cost).
Crop Requirements for Stability:
Crops sensitive to environmental fluctuations (e.g., seedlings, strawberries): Choose 200μm films, as they are more stable and reduce film vibration caused by wind, avoiding drastic temperature and humidity fluctuations.

II. Film Types: High-transparency Film, Diffused Film, etc. Match Crops and Light Conditions
The key differences between film types lie in light transmittance, light distribution, and functional characteristics (anti-fog, anti-aging, etc.). Selection should be based on crop light requirements and local light conditions:

1. High-transparency Film (Light Transmittance ≥90%): "Sunlight Accelerator" for Strong Light
Core Features: Maximizes the transmission of direct light, enhances photosynthetic efficiency, suitable for crops with high light demands.
Applicable Scenarios:
Crops: Fruit and vegetable crops (tomatoes, cucumbers, peppers), tropical flowers (roses, orchids) that require sufficient light for fruiting and color development.
Regions: High-latitude/weak light areas (e.g., Northern Europe, Southern Canada), cloudy and rainy areas (e.g., UK, New Zealand) to compensate for insufficient natural light.
Note: In tropical midday strong light (e.g., Middle East, inland Australia), external sunshade nets should be used to avoid crop leaf burn.

2. Diffused Film (Light Transmittance 85%-90%): "Balance Master" for Uniform Light
Core Features: Converts direct light into diffused light, resulting in more uniform light distribution, avoiding local strong light burn, and allowing middle and lower leaves of crops to receive light.
Applicable Scenarios:
Crops: Leafy vegetables (lettuce, spinach), seedlings (which are sensitive to strong light), densely planted crops (e.g., strawberries, medicinal plants) to reduce leaf yellowing and uneven growth.
Regions: Low-latitude/strong light areas (e.g., Thailand, Brazil), areas with extremely strong summer light (e.g., Arizona, USA) to reduce the risk of crop "light stress".

3. Other Essential Types: Choose Based on Specific Needs
Anti-fog Film (Drip Film)
Function: Prevents condensation on the inner surface of the film, avoiding water droplets from wetting crop leaves and reducing diseases (e.g., mold, downy mildew).
Applicable Regions: High-humidity areas (e.g., Southeast Asia during rainy season, Amazon Basin in South America) and for growing humidity-sensitive crops (e.g., lettuce, herbs).
Anti-aging Film (UV-resistant Film)
Function: Contains UV stabilizers to delay film embrittlement and cracking caused by direct sunlight.
Applicable Regions: Areas with extremely strong UV radiation (e.g., South Africa, Middle East, Australia), extending service life by 2-3 years compared to ordinary films.
Insulating Film (Infrared Blocking Film)
Function: Allows visible light to pass through while blocking infrared radiation (heat) loss, improving nighttime insulation by 5-8°C.
Applicable Regions: Areas with large day-night temperature differences (e.g., Mediterranean coast, Xinjiang China, Western USA) and for cultivation in cold seasons (e.g., winter lettuce in Europe).

III. Decision-making Steps for New Buyers: 3 Steps to Lock in the Best Choice
First, Consider Local "Light + Climate":
Strong light/high UV areas (e.g., Middle East): 200μm + diffused film + anti-aging film
Weak light/cloudy areas (e.g., Northern Europe): 150μm + high-transparency film
High humidity/rainy areas (e.g., Southeast Asia): 200μm + anti-fog film
Areas with large day-night temperature differences (e.g., Central Asia): 200μm + insulating film
Next, Clarify the Crops to Be Grown:
Light-loving fruiting crops (tomatoes, peppers): Prioritize high-transparency films.
Shade-tolerant leafy vegetables/seedlings: Prioritize diffused films.
Humidity-sensitive crops (herbs, strawberries): Must have anti-fog function.
Finally, Calculate the "Lifecycle Cost":
Short-term (1-3 years): 150μm basic models (e.g., high-transparency/diffused) to reduce initial investment.
Long-term (5+ years): 200μm functional models (e.g., anti-aging + anti-fog) to reduce replacement frequency.
