PP seed Bag Resealable Flat Bag Moisture & UV Proof for Vegetable Seeds

Product Overview: 
This product is a heavy-duty woven seed packaging bag made from BOPP (biaxially oriented polypropylene), specifically designed for packaging various seeds, including vegetable and grain seeds. BOPP offers high transparency, excellent gloss, superior moisture resistance, and outstanding tensile strength; combined with a thickened construction, it ensures the safe storage and transportation of seeds. The bag features a large, dedicated printing area that can be customized with brand logos, variety information, planting instructions, and other content, fully complying with relevant seed-labeling regulations.

Applicable materials: 
Vegetable seeds (tomato, cucumber, pepper, Chinese cabbage, radish, etc.), grain seeds (corn, wheat, rice, soybean, peanut, etc.), flower seeds, forage seeds, turfgrass seeds, field crop seeds, and other horticultural and agricultural seeds.

Core Advantages: 
Made from high-transparency, high-gloss BOPP material; thickened design for enhanced puncture resistance; excellent moisture-barrier performance; compatible with high-speed filling lines; customizable printing area; compliant with seed-labeling regulations.

BOPP material characteristics: 
High transparency: Allows visibility of the contents, enhancing consumer trust.

High gloss: vibrant print colors and excellent brand presentation

High strength: resistant to stretching and puncture, and not easily torn.

Moisture resistance: Low water vapor transmission rate, effectively preserving seed viability.

Material and Craftsmanship: 
Base material: BOPP (Biaxially Oriented Polypropylene)

Structure: BOPP film + PP/HDPE woven fabric composite

Bag Type: Flat Pocket / M-Edge Pocket (optional)

Bottom style: sewn bottom / heat-sealed bottom / ultrasonic-sealed bottom

Thickness: Thickened design (grammage can be customized upon request)

Moisture resistance: 
BOPP material exhibits low water vapor transmission, and when combined with a thickened woven fabric layer, it effectively prevents seeds from becoming damp and moldy, thereby reducing the germination rate and extending the shelf life to over 12 months. Optional PE inner liners or aluminum foil layers can be added to further enhance moisture-barrier performance.

Breathability (optional): 
For seeds that require breathable storage, laser micro-perforation is an optional process with customizable pore size and density, striking a balance between moisture resistance and gas permeability to ensure seed viability during storage.

Tensile strength: 
≥700 N/50 mm (30% above the national standard), suitable for stacking and transporting loads ranging from 1 to 25 kg.

Packaging drop test: 
With a 25 kg load, it can withstand a 1.2-meter free fall and six-sided drop tests without cracking or leaking.

Customization for the printing area: 
Printing area: Supports large-area, multi-color overprinting with crisp, vibrant graphics.

Printable information: brand logo, variety name, net content, four quality indicators—purity, fineness, germination rate, and moisture content—implementation standard number, seed production and business license number, variety approval number, testing date, shelf life, place of origin, manufacturer’s name and address, planting instructions, and QR code/barcode (scannable for traceability).

Special Techniques: Local UV Coating, Gold Foil Stamping, Matte/Gloss Lamination (optional)

Warning Labels: Can be printed with warnings such as “Moisture-Proof,” “Sunlight-Resistant,” and “Do Not Consume Coated Seeds.”

Sealing method: 
After filling, optional sealing methods include stitch-sealing, heat-sealing, ultrasonic sealing, or tie-sealing.

Applicable filling method: 
Compatible with screw fillers, impeller fillers, seed-specific metering fillers, and manual filling.

Corrosion resistance grade: 
★★★★ (Highly tolerant to the oils and coating agents in the seed.)

Environmental Compliance: 
New BOPP and woven fabric raw materials are produced and are recyclable. Export certification is supported.
