Growing Demand for Weather-Resistant Agricultural Films
Agricultural films are essential materials in modern agriculture and are widely used in:
- Greenhouse films;
- Long-life agricultural covering films;
- Mulch films;
- Silage films.
During outdoor service, agricultural films are continuously exposed to:
- Strong UV radiation;
- Temperature fluctuations;
- High humidity and heat;
- Pesticide and fertilizer residues.
These factors accelerate photo-oxidative degradation of polyethylene (PE), causing:
- Film embrittlement;
- Loss of tensile strength;
- Cracking and failure;
- Reduced light transmission;
- Shortened service life.
Therefore, modern agricultural films require not only good mechanical properties, but also:
- Long-term UV resistance;
- Low migration stability;
- Excellent processing compatibility;
- Competitive overall cost.
HALS 119, a high molecular weight hindered amine light stabilizer, has been widely applied in polyolefin systems and has established a proven track record in agricultural films and other long-life outdoor applications.
1. Key Advantages of HALS 119 in Agricultural Film Applications
1. Mature Technology Compatible with Existing Film Processing
Agricultural films are typically produced through:
- Blown film extrusion;
- Masterbatch addition;
- High-speed continuous processing.
During production, light stabilizers must provide:
- Excellent dispersion;
- Stable processing performance;
- No negative impact on film transparency;
- Good compatibility with PE resin.
HALS 119 offers a high molecular structure and excellent processing stability, making it highly compatible with PE agricultural film systems.
For agricultural film manufacturers, introducing HALS 119 does not require major changes to existing production processes:
- Existing blown film equipment can be maintained;
- Current processing parameters can be retained;
- Performance improvement can be achieved through masterbatch or direct blending.
This reduces development time and production risks.
2. Why HALS 119 Is Suitable for Long-Term Outdoor Agricultural Applications
1. Excellent Migration Resistance
Agricultural films are often required to maintain performance for:
- Several months;
- Multiple growing seasons;
- Long-term outdoor exposure.
If a light stabilizer migrates or is lost too quickly, the long-term protection efficiency will decline.
HALS 119 provides:
- High molecular weight;
- Low volatility;
- Low migration characteristics.
It remains effectively distributed within the PE matrix and continuously captures free radicals generated during photo-oxidation, slowing polymer degradation.
2. Strong Adaptability to Agricultural Environments
Agricultural films may be exposed to:
- Insecticides;
- Fungicides;
- Fertilizer residues;
- Hot and humid environments.
HALS 119 demonstrates good environmental stability and is suitable for demanding agricultural applications, including:
- Long-life greenhouse films;
- High-performance agricultural films;
- Premium crop protection films.
3. Cost Advantages of HALS 119 in Agricultural Films
When selecting a light stabilizer, many manufacturers focus only on the price per kilogram. However, the more important factor is:
The actual additive cost per ton of finished agricultural film.
Through optimized formulation design, HALS 119 can deliver high stabilization efficiency with controlled dosage.
Cost optimization can be achieved by adjusting:
- HALS dosage;
- UV absorber ratio;
- Antioxidant system.
The optimized HALS 119 formulation provides:
- Higher additive efficiency;
- Lower cost contribution per ton;
- Stable long-term weathering performance.
For agricultural film producers, the value is not only lower additive cost, but also:
- Reduced risk of premature film failure;
- Fewer customer complaints;
- Longer product lifetime.
4. HALS 119 Application Optimization Process
Step 1: Easy Integration into Existing Production
HALS 119 can be introduced into current agricultural film systems without major process changes:
- PE resin remains unchanged;
- Existing blown film equipment can be used;
- Standard processing temperatures can be maintained.
It can be added through:
- Functional masterbatch;
- Pre-blended additives;
- Direct compounding.
Step 2: Optimize Dosage for Best Cost Performance
A dosage optimization study can be conducted:
0.20%

0.08%Performance evaluation includes:
- Xenon accelerated weathering;
- Tensile strength retention;
- Light transmission retention;
- Color change;
- Long-term outdoor durability.
The goal is to identify the lowest dosage that meets the required service life.
Step 3: Establish Long-Term Validation
To ensure real-field performance, testing should include:
- Accelerated aging;
- Natural weather exposure;
- Chemical resistance testing.
Key evaluation factors:
- Flexibility retention;
- Crack resistance;
- Service life;
- Appearance stability.
