UV Stabilizer Masterbatch
Most critical additive masterbatch protecting LDPE/EVA greenhouse films from photodegradation during continuous outdoor exposure throughout greenhouse service life. Greenhouse films must maintain full mechanical integrity and optical performance for minimum 3 to 5 years requiring precisely calibrated HALS stabilizer system in all film layers.
White Masterbatch
Delivers high light reflection and bright white opacity to outer layer of greenhouse films for heat management and light distribution inside greenhouse structures. High TiO₂ loading in white layer reflects excess solar radiation reducing internal greenhouse temperature during summer months critical for cool season vegetable and floriculture production.
Antioxidant Masterbatch
Prevents thermal and oxidative degradation of LDPE/EVA/LLDPE resin during blown film extrusion and throughout greenhouse film outdoor service life. Combined Irganox 1076 and Irgafos 168 antioxidant package maintains long-term film tensile strength, elongation, and puncture resistance critical for greenhouse films subjected to wind, hail, and mechanical stress.
Anti-Fog Masterbatch
Reduces raw material cost in standard grade PP monofilament yarn for rope, twine, and packaging applications without significantly affecting basic tensile properties. Improves filament stiffness and helps achieve required denier consistency in coarser diameter monofilament yarn used in woven sack tape and agricultural twine applications.
Light Diffuser Masterbatch
Creates controlled light scattering inside greenhouse by converting direct sunlight into diffuse radiation that penetrates uniformly into crop canopy. Uniform diffuse light distribution eliminates shadow zones, reduces photoinhibition in upper leaves, and improves photosynthetic efficiency throughout entire crop height .
Slip Masterbatch
Reduces coefficient of friction of greenhouse films for smooth installation on greenhouse structures and high-speed performance on film manufacturing equipment. Precisely balanced slip agent dosage improves film handling during greenhouse covering operations without causing film slippage from tensioning wires.
Processing Aid Masterbatch
Eliminates melt fracture and sharkskin defects during co-extrusion of multi-layer greenhouse films at high line speeds on wide blown film lines. Reduces die pressure, improves film surface smoothness, and ensures consistent gauge uniformity across full film width critical for uniform optical and mechanical properties l.
Antimicrobial Masterbatch
Prevents algae, moss, and microbial growth on outer surface of greenhouse films that reduces light transmission over time. Silver-ion or zinc-based antimicrobial compounds prevent biological fouling on greenhouse film surface maintaining high light transmission levels throughout film service life in humid and warm greenhouse environments.
Biodegradable Masterbatch
Promotes controlled soil biodegradation of low tunnel and seasonal greenhouse films after crop season eliminating agricultural plastic waste collection burden. Based on certified compostable PBAT or PLA polymer compounds meeting EN 13432 and ASTM D6400 compostability standards addressing growing regulatory requirements.
Flame Retardant Masterbatch
Imparts fire-resistant and self-extinguishing properties to greenhouse films used in enclosed permanent greenhouse structures with heating systems. Helps greenhouse films meet fire safety requirements for permanent agricultural structures with gas heating, electrical systems, and automated climate control equipment.
Antistatic Masterbatch
Reduces static charge accumulation on greenhouse film surfaces during production, winding, and installation operations. Prevents dust and soil particle adhesion to greenhouse film outer surface that can reduce light transmission and create shading effects compromising crop photosynthesis and production efficiency.
