Jiangsu Dangkang Plastic Industry Co., Ltd The Evolution of Agricultural Film Development in China: From Basic PE Film to High-Performance Greenhouse Solutions
Agricultural film has played a transformative role in the modernization of Chinese agriculture. Over the past several decades, China has evolved from producing simple plastic mulch films to becoming one of the world's largest manufacturers and exporters of advanced greenhouse covering materials. Today, Chinese agricultural film factories supply innovative solutions to farmers in more than 100 countries, offering products such as PO film, PE film, EVA film, heat shrink film, and specialized fireproof film for agricultural and industrial applications.
This article explores the history of agricultural film development in China and explains why Chinese manufacturers have become global leaders in agricultural plastic technology.
The Early Development of Agricultural Film in China
China began researching agricultural plastic films in the late 1950s. During the 1970s, polyethylene-based films were gradually introduced into farming to improve crop production during colder seasons.
The widespread adoption of PE film (Polyethylene Film) revolutionized protected agriculture by allowing farmers to:
-
Extend growing seasons
-
Increase crop yields
-
Reduce water evaporation
-
Protect crops from harsh weather
-
Improve fertilizer efficiency
As greenhouse cultivation expanded rapidly throughout China, the demand for higher-quality agricultural films also increased.
The Rise of Chinese Agricultural Film Factories
During the 1980s and 1990s, numerous Chinese agricultural film factories invested heavily in modern extrusion technology and polymer research. These manufacturers shifted from producing basic polyethylene films to developing multi-layer co-extruded greenhouse films with significantly improved performance.
Today, many Chinese manufacturers operate:
-
3-layer co-extrusion lines
-
5-layer blown film production systems
-
Advanced quality inspection laboratories
-
UV stabilization testing facilities
-
Weather resistance research centers
This technological progress has enabled China to become one of the largest exporters of agricultural plastic films worldwide.As a Chinese company Committed to creating high-quality agricultural films, Jiangsu Dangkang Plastic Industry Co., Ltd. is currently developing a 7-layer co-extrusion machine, which will be put into production in 2027.
PE Film: The Foundation of Modern Agriculture
Among all greenhouse covering materials, PE film remains the most widely used due to its excellent balance of affordability and performance.
Key advantages include:
-
High transparency
-
Excellent flexibility
-
Strong mechanical strength
-
Easy installation
-
Cost-effective production
PE film is commonly used for:
-
Vegetable greenhouses
-
Fruit cultivation
-
Mulching
-
Tunnel greenhouses
-
Livestock facilities
Modern PE greenhouse films often include UV inhibitors and anti-drip additives that significantly improve crop performance.
PO Film: A New Generation of Greenhouse Covering
As greenhouse technology advanced, PO film (Polyolefin Film) became increasingly popular among commercial growers.
Compared with traditional PE film, PO film offers:
-
Higher light transmission
-
Better thermal insulation
-
Longer service life
-
Superior weather resistance
-
Lower dust accumulation
-
Better anti-fog performance
These advantages make PO film particularly suitable for high-value crops such as:
-
Tomatoes
-
Strawberries
-
Cucumbers
-
Flowers
-
Seedlings
Many growers searching for the best greenhouse film in China now choose PO film because of its excellent durability and crop-growing performance.
EVA Film: Excellent Heat Preservation
Another important milestone in China's agricultural film development is EVA film (Ethylene Vinyl Acetate Film).
EVA film is well known for its outstanding thermal insulation properties.
Its main benefits include:
-
Excellent heat retention
-
High light transmittance
-
Soft texture
-
Strong flexibility
-
Improved cold resistance
EVA greenhouse films are especially popular in regions experiencing low winter temperatures because they help maintain stable greenhouse climates while reducing heating costs.
Heat Shrink Film Beyond Agriculture
Although primarily associated with industrial packaging, heat shrink film has become an important complementary product for many agricultural film manufacturers.
Chinese factories produce high-quality heat shrink films used for:
-
Agricultural equipment packaging
-
Seed packaging
-
Fertilizer packaging
-
Greenhouse accessories
-
Industrial transportation
With advanced production technology, Chinese heat shrink films offer excellent shrink ratios, puncture resistance, and clarity.
Fireproof Film for Enhanced Safety
As greenhouse structures become larger and more technologically advanced, safety has become an increasingly important consideration.
Modern fireproof film incorporates flame-retardant additives that help slow flame propagation and improve overall safety in agricultural facilities.
Applications include:
-
Commercial greenhouses
-
Agricultural warehouses
-
Livestock buildings
-
Industrial storage
-
Temporary protective structures
Although fireproof film cannot completely prevent fire, it provides valuable additional protection by reducing flame spread and increasing evacuation time.
Why Chinese Manufacturers Lead the Global Market
Today, Chinese agricultural film factories are recognized for combining competitive pricing with continuous technological innovation.
Leading manufacturers invest in:
-
Multi-layer co-extrusion technology
-
Imported raw materials
-
UV stabilization systems
-
Anti-drip technology
-
Anti-dust coatings
-
Infrared heat preservation additives
-
Quality management systems
Many factories also provide customized agricultural film solutions for different climates, greenhouse designs, and crop varieties.
Choosing the Best Greenhouse Film in China
Selecting the best greenhouse film in China depends on several factors:
Climate
Cold regions benefit from EVA or insulated PO films, while warmer climates often use standard PE films.
Crop Type
High-value vegetables and flowers generally require films with excellent light transmission and anti-fog performance.
Service Life
Professional growers often prefer multi-season films that can remain effective for three to five years.
Light Transmission
Higher transparency improves photosynthesis and promotes healthier plant growth.
UV Protection
Quality greenhouse films contain UV stabilizers that reduce degradation caused by sunlight.
The Future of Agricultural Film in China
China continues to invest in advanced agricultural materials as smart farming and sustainable agriculture expand worldwide.
Future innovations are expected to include:
-
Biodegradable agricultural films
-
Smart greenhouse covering materials
-
Infrared energy-saving films
-
Nano-coated greenhouse films
-
Recyclable agricultural plastics
-
Environmentally friendly polymer technologies
These developments will further strengthen China's position as a global supplier of high-performance agricultural films.
Conclusion
The history of agricultural film development in China reflects decades of technological innovation and continuous improvement. From the early adoption of PE film to the development of advanced PO film, EVA film, heat shrink film, and specialized fireproof film, Chinese manufacturers have consistently expanded the capabilities of modern agricultural plastics.
Today, Chinese agricultural film factories serve growers around the world with reliable, durable, and cost-effective greenhouse solutions. Whether you're searching for the best greenhouse film in China or exploring advanced materials for protected agriculture, China's agricultural film industry continues to set new standards in quality, innovation, and global supply.
