Custom PP Woven Bag – For Fertilizer/Granules/Powder, Moisture & UV Resistant, Print Ready

Applicable materials: 
Compound fertilizers, urea, potash fertilizers, phosphate fertilizers, organic fertilizers, bio-organic fertilizers, blended fertilizers (BB fertilizers), water-soluble fertilizers, controlled-release and slow-release fertilizers, nitrate-based fertilizers, and other granular or powdered chemical fertilizer products.

Key features: 
The bag opening is smooth and easy to open and fill, making it compatible with a wide range of filling equipment. A laminated outer layer combined with an inner liner provides double protection against moisture and leakage, ensuring the fertilizer maintains its quality and does not cake. The sealing method is versatile, supporting seam-sealing, heat-sealing, ultrasonic sealing, and other techniques. The bag body is flat and stable for stacking, making it suitable for long-distance transportation. Cost-effective, this design reduces material costs by 8% to 12% compared with M-edge bags, making it ideal for bulk procurement.

Core Advantages: 
Moisture-proof and anti-caking, tensile strength and burst resistance, cost-effective, compatible with multiple filling methods, easy to seal, easy to palletize, and resistant to fertilizer corrosion.

Material and Craftsmanship: 
The base material is woven PP (polypropylene) or HDPE (high-density polyethylene) fabric, with a PE barrier film laminated on the inner layer (either as a laminated coating or as a co-extruded liner). The bag style is a flat-bottom pouch, with options for sewn bottom, heat-sealed bottom, or ultrasonically sealed bottom. Printing is carried out using 2- to 7-color rotogravure color printing with lamination, resulting in vibrant, abrasion-resistant, and fertilizer-corrosion-resistant graphics.

Sealing method: 
After filling, optional sealing methods include stitch-sealing lines, heat-sealing (requiring an inner bag), ultrasonic sealing, or tie-sealing.

Applicable filling method: 
Suitable for screw fillers, impeller fillers, pneumatic fillers, gravity fillers, trough-belt fillers, and manual filling.

Tensile strength: 
≥700 N/50 mm (30% above the national standard), suitable for stacking and transporting loads weighing 25 to 50 kg.

Moisture resistance: 
The water vapor transmission rate is reduced by more than 90% (due to the laminated film and inner-bag structure), effectively preventing fertilizer from becoming damp and caked and minimizing nutrient loss, thereby extending the shelf life to over six months.

Corrosion resistance grade: 
★★★★★ (Highly resistant to acidic and alkaline components, salts, and various additives in fertilizers.)

Packaging drop test: 
With a 50 kg load and a 1.2-meter free fall, it remains unbroken and leak-proof after being dropped on all six sides.

Printing standards: 
Solvent-resistant ink, compliant with the Fertilizer Packaging Labeling Standard (GB 18382). Barcode/QR code scan rate: 100%.

Customization Scope: 
Multi-color overprinting of the brand logo, product name, nutrient content (N-P-K), instructions for use, and fertilization recommendations. Optional inclusion of warning labels such as “Keep Dry,” “Protect from Sunlight,” “Do Not Mix with Seeds,” and “Not Suitable for Chlorine-Sensitive Crops,” as well as barcodes, QR codes, metrology markings, and environmental recycling symbols.

Environmental Compliance: 
Made from virgin materials and recyclable. Supports hazardous packaging export certification.

Packaging specifications: 
Customizable: loading weight (25 to 50 kg, with 25 kg, 40 kg, and 50 kg being common), bag dimensions (length × width), sealing method, number of inner liner layers (single or double), and print area (single-sided, double-sided, or full-color).

Applicable to: 
Compound fertilizer manufacturers, urea/potash/phosphate fertilizer plants, organic fertilizer producers, bio-organic fertilizer manufacturers, blended fertilizer processing enterprises, water-soluble fertilizer producers, and fertilizer export traders. 。
