Color-printed, laminated, flat-mouth woven fertilizer packaging bags

Applicable materials: 
Compound fertilizers, urea, potash fertilizers, phosphate fertilizers, organic fertilizers, bio-organic fertilizers, blended fertilizers (BB fertilizers), water-soluble fertilizers, controlled- 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 dual moisture and leak protection, ensuring the fertilizer remains free of caking. Flexible sealing options accommodate seam-sealing, heat-sealing, ultrasonic sealing, and other methods. The bag body is flat and stable for stacking, with excellent resistance to long-distance transportation. Cost-effective: compared with M-edge bags, it reduces material costs by 8% to 12%, 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 flat-bottomed, with optional bottom-sealing options including 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: 
Compatible with 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, a 1.2-meter free fall, and six-sided drop tests, the product remains intact and leak-proof.

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 common options of 25 kg, 40 kg, and 50 kg), bag dimensions (length × width), sealing method, number of inner liner layers (single or double), and printing 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. 。
