Manufacturing Process and Raw Material Advantages

This product is manufactured using seven-layer co-extrusion technology. Compared to traditional single-layer or three-layer co-extruded greenhouse films, the seven-layer co-extrusion process enables precise compounding of different functional layers, integrating anti-fogging, drip-resistance, heat retention, and weather resistance into separate layers, thereby avoiding performance degradation in individual functional layers and enhancing the overall structural stability of the film. The core raw material selected is Korea-imported EVA2050 ethylene-vinyl acetate copolymer, which inherently possesses excellent flexibility, weather resistance, and light transmittance. When paired with metallocene resin, it further enhances the film's tensile strength, puncture resistance, and rigidity, ensuring fundamental product performance at the raw material level. In contrast to ordinary PE films that rely solely on general-purpose polyethylene, this product's raw material combination fundamentally addresses the inherent defects of ordinary PE films—such as rapid aging, insufficient strength, and low light transmittance—providing raw material-level support for long-term stable use.

Key Advantages

Compared to traditional ordinary PE greenhouse films, the key advantages of this product are primarily reflected in the following aspects:
1. High Transparency and Low Haze: With a light transmittance exceeding 90% and haze below 17%, its high-gloss, high-transparency characteristics ensure ample indoor lighting, reducing the impact of insufficient illumination on crop photosynthesis. This makes it particularly suitable for flower, seedling, and fruit-vegetable cultivation scenarios with high light requirements.
2. High Strength and Puncture Resistance: The raw material combination featuring metallocene resin and the seven-layer co-extrusion structure design give the product outstanding tensile strength, puncture resistance, and high rigidity, enabling it to withstand damage from extreme weather events such as strong winds and hail, while also preventing accidental punctures caused by farming tools or branches during routine agricultural operations, thus lowering maintenance costs.
3. Excellent Heat Retention: With heat retention improved by 1–3°C compared to standard PE films, this product effectively reduces heat loss indoors during winter or low-temperature periods, maintaining an appropriate temperature environment, protecting crops from cold damage, and simultaneously decreasing energy consumption from indoor heating equipment, thereby reducing cultivation costs.
4. Ultra-long Durability: The product boasts a continuous service life of over 12 months. Compared to the mere 3–6 months of ordinary PE films, this significantly reduces annual labor and material costs associated with replacing greenhouse films, making it especially ideal for long-season fruit and vegetable cultivation, where mid-cycle film replacement could disrupt crop growth.
5. Anti-fogging and Drip-resistance Functionality: Equipped with stable anti-fogging and drip-resistance capabilities, this product prevents condensation droplets from forming inside the greenhouse and dripping onto crop leaves or fruits, reducing the incidence of crop diseases while also avoiding light obstruction by droplets, ensuring uniform indoor illumination.

Core Value of the Product

The core value of this product is crafted around the actual needs of growers, primarily manifested in the following dimensions:
1. Enhanced Crop Yield and Quality: High light transmittance ensures sufficient illumination for crops, boosting photosynthetic efficiency; improved heat retention maintains optimal growing temperatures; and anti-fogging/drip-resistance functions reduce disease occurrence. With these multifaceted performance enhancements, crop yield and quality can be effectively improved, making it particularly suitable for mid-to-high-end vegetable, flower, and melon/fruit cultivation, helping growers increase their farming income.
2. Reduced Long-term Cultivation Costs: An ultra-long service life of over 12 months decreases the frequency of film replacements, lowering material and labor expenses; excellent puncture resistance reduces repair frequency, cutting maintenance costs; and enhanced heat retention decreases winter heating energy consumption, further reducing overall cultivation costs.
3. Adaptation to Demanding Cultivation Scenarios: The product's comprehensive performance meets the high demands for light transmission and heat retention in long-season fruit and vegetable greenhouses, flower greenhouses, and professional seedling nurseries, helping growers achieve off-season and extended-cycle cultivation goals, thereby expanding their revenue potential.

Target Customer Base

This product is primarily targeted at growers with high performance expectations for greenhouse films, specifically including mid-to-high-end vegetable farmers, flower growers, melon/fruit growers, agricultural cooperatives, and professional seedling nurseries. These customer groups typically have stringent requirements for crop yield and quality, coupled with extended cultivation cycles, and are willing to opt for premium greenhouse films that deliver superior performance and lower long-term usage costs to maximize farming returns.

Application Scenarios

The application scenarios for this product mainly focus on greenhouses with high demands for light transmission and heat retention, specifically including long-season fruit and vegetable greenhouses, flower greenhouses, and professional seedling greenhouses. Among these, long-season fruit and vegetable cultivation requires greenhouse films with exceptionally long service lives to avoid disrupting continuous growth due to mid-cycle replacements; flower cultivation places high emphasis on uniform light distribution and stable indoor temperature and humidity, which this product's high light transmittance, low haze, anti-fogging/drip-resistance, and heat retention features can fully satisfy; and seedling cultivation imposes strict requirements on indoor temperature and light stability, where the product's 1–3°C heat retention boost and high light transmittance characteristics can provide an ideal environment for seedling growth, improving survival and robustness rates.

Industry Pain Points Addressed

This product is specifically designed to address the inherent pain points of traditional ordinary PE greenhouse films, effectively resolving the following common industry issues:
1. Low Transparency and High Haze of Ordinary PE Films: Conventional PE films typically offer only 70%–80% light transmittance and exhibit high haze, often leading to insufficient indoor illumination and impaired crop photosynthesis. This product's light transmittance exceeding 90% and haze below 17% fully guarantee adequate indoor lighting conditions.
2. Insufficient Strength and Prone to Puncture Damage of Ordinary PE Films: Ordinary PE films suffer from low tensile strength and poor puncture resistance, making them susceptible to damage from strong winds, hail, or agricultural activities, thereby increasing maintenance costs. This product, featuring metallocene resin-enhanced raw materials and a seven-layer co-extrusion structure, effectively boosts strength and puncture resistance.
3. Rapid Aging and Short Service Life of Ordinary PE Films: Conventional PE films usually last only 3–6 months before aging and becoming brittle, necessitating frequent replacements and driving up cultivation costs. This product's continuous service life of over 12 months significantly reduces replacement frequency.
4. Poor Heat Retention of Ordinary PE Films: Standard PE films exhibit weak heat retention, causing rapid temperature loss in greenhouses during winter and increasing the risk of crop frost damage while also elevating heating energy consumption. This product's heat retention improved by 1–3°C over conventional PE films effectively maintains indoor temperatures and lowers energy usage.
5. Inadequate Anti-fogging and Drip-resistance Performance of Ordinary PE Films: The anti-fogging and drip-resistance functions of ordinary PE films are short-lived, frequently resulting in indoor fog and dripping water, which heightens the risk of crop diseases. This product's stable anti-fogging and drip-resistance capabilities effectively prevent these issues.
