Black and White LLDPE Grow Bags
At PolyNova Packaging, engineered agricultural polymer solutions are manufactured at our state-of-the-art facility in Pollachi, Tamil Nadu. Our Black and White LLDPE Grow Bags provide optimal root zone environment control for hi-tech horticulture, polyhouse cultivation, hydroponic setups, open-field farming, and commercial nurseries.
Black Grow Bags
Engineered with high-density carbon black pigmentation, single-layer black grow bags offer 100% opacity. This complete light barrier prevents light penetration to the root core, totally suppressing algae growth, weed germination, and root light degradation. Black grow bags absorb ambient soil warmth during early propagation seasons, stimulating faster root establishment.
White Grow Bags
Utilizing high-grade titanium dioxide (TiO2) pigments, white grow bags reflect over 80% of solar radiation. By bouncing back harsh sunlight and thermal UV radiation, they prevent root burning and keep substrate temperatures 5°C to 8°C cooler than traditional dark pots during hot tropical summers, safeguarding delicate feeder roots.
Dual-Color Co-Extrusion
Our flagship Black & White Co-Extruded Grow Bags combine both benefits into a single multi-layer film. The outer white layer reflects solar heat to keep root zones cool, while the inner black layer blocks light internally to stop algae growth. This dual-action mechanism creates an ideal microclimate for hydroponics and polyhouse crops.
100% Virgin LLDPE Material
Manufactured exclusively using 100% virgin Linear Low-Density Polyethylene (LLDPE) resins. Our material is heavy-metal free, non-toxic, chemical-resistant, and entirely safe for organic crops, vegetable farming, and edible fruit plants. LLDPE offers superior tensile strength and puncture resistance compared to standard recycled poly films.
Thickness & Gauge Options
PolyNova grow bags are manufactured across heavy-duty gauge spectrums ranging from 100 to 200+ Microns (400 to 800+ Gauge). Heavy micron ratings ensure structural rigidity when filled with soil, coco peat, or substrate mixtures without side-wall sagging, tearing, or split seams during handling.
3 to 5 Years UV Stabilization
Compounded with masterbatch Hindered Amine Light Stabilizers (HALS), our grow bags withstand prolonged outdoor solar exposure. Designed for long crop cycles, they resist embrittlement, cracking, and degradation in tropical climates for 3 to 5 years, enduring high solar radiation without failing.
Multi-Tier Drainage & Air Pruning
Equipped with precision-punched multi-tier drainage holes along the lower sidewalls and bottom fold. This prevents waterlogging, anaerobic root rot, and fertilizer salt buildup. The perforation layout encourages natural air-pruning, preventing root circling and promoting dense lateral root branching.
