Organic nutrient soil woven bag / Flower planting soil PP woven bag / Home gardening nutrient soil woven bag / Waterproof and moisture-proof nutrient soil woven bag

This product is a specialized woven outer bag designed for organic nutrient soil. The front features full-color printing, clearly highlighting “Organic Nutrient Soil,” “ORGANOTROPHIC SOIL,” the net content (28 liters), and key selling points: organic matter ≥ 65%, pH 5.5–7.5, and excellent water‑retention, fertilizer‑holding, and air‑permeability properties. The bag adopts an M‑side stand‑up design, allowing it to stand upright after filling—ideal for retail display and efficient stacking in storage. Paired with an inner liner or laminating process, it provides effective waterproofing, moisture resistance, and nutrient‑preservation performance.

Applicable Materials

Suitable for packaging organic nutrient soil (universal type); material parameters are as follows:

Organic matter content ≥65%

pH 5.5–7.5

The formula is derived from European home gardening recipes.

It possesses water-retention, nutrient-retention, and aeration properties.

Core Advantages

Waterproof, moisture‑resistant, and nutrient‑retentive: The bag is coated or lined with a moisture‑barrier layer, effectively blocking external moisture to prevent the growing medium from absorbing moisture and clumping, as well as to minimize nutrient loss.

M‑side stand-up pouch: The empty pouch can be folded for transport, and after filling, the bottom automatically unfolds, ensuring stable upright positioning and enhancing shelf‑display appeal.

Durable for outdoor stacking: The woven base fabric is high-strength and resistant to aging, making it ideal for open-air storage or long-distance transportation and less prone to tearing.

Color-printed brand presentation: High-definition, multi-color printing enhances brand recognition and conveys quality signals such as “European formulation” and “high organic content.”

Features

M‑side stand-up pouch: features a double‑folded side seal, allowing the empty pouch to lie flat; once filled, it automatically expands into a three‑dimensional square shape, saving storage space.

Waterproof, moisture‑resistant, and mildew‑proof: Featuring a laminated surface or an inner PE film liner, it boasts a low water vapor transmission rate, ensuring long‑term storage without mold growth.

Color-printed brand display: Full‑surface printing on both the front and back, with vibrant graphics that are scratch‑resistant; can feature user instructions, the brand logo, QR codes, and more.

Performance

Waterproof and moisture‑resistant performance: The outer woven fabric is coated with a laminated layer (or equipped with an inner PE liner bag). When stored at a relative humidity of 80% for 30 days, the moisture content of the nutrient soil inside the bag increases by no more than 1.5%.

Outdoor stacking durability: The base fabric is formulated with UV‑stabilizing additives; after two months of continuous exposure to outdoor conditions—stacked up to five layers high and subjected to sun and rain—the bag shows no chalking, no significant fading, and the seams remain intact.

Tensile strength: longitudinal tensile strength ≥ 450 N/50 mm, transverse ≥ 400 N/50 mm (in accordance with GB/T 8946), capable of supporting 25–30 kg of wet soil.

Packaging drop test: After filling with 28 liters of potting soil (total weight approximately 22–28 kg), the package is dropped freely from a height of 1.2 meters onto a concrete floor. The bag remains intact, with no tears or seam separations, and no contents are spilled.

Material and Craftsmanship

Base material: virgin polypropylene (PP) woven fabric, with a density of ≥10×10 threads per inch and a basis weight of 75–90 g/m².

Lamination/Lining: Optional lamination with PE film (15–30 μm thick) or an independent PE inner bag (5–8 mils thick), with secure heat sealing.

Printing process: gravure color printing, double-sided or single-sided, with color fastness of ≥ Grade 4 (dry rubbing).

Bag Formation: The M‑edge (folded edge) automatic bag-making machine forms bags in a single step, with bottoms that can be heat‑sealed or sewn.

Tensile strength

Longitudinal tensile strength: ≥450 N/50mm

Weft tensile strength: ≥400 N/50 mm

Seam tensile strength: ≥300 N/50 mm (seam area)

UV‑aging resistance: After 120 hours of QUV testing, the strength retention rate is ≥80%.

Packaging drop test

Test method: Fill with 28 liters of potting soil (actual weight approximately 26 kg), seal the container, and then drop it freely from a height of 1.2 meters, following the “one corner, three edges, six faces” pattern.

Acceptance criteria: The bag body shall be free of tears, the inner liner shall be undamaged, the seams shall remain intact without slippage, and no material leakage shall occur.

Results: Compliant with the requirements of GB/T 8946-2013 and suitable for standard logistics and transportation.

Applicable filling method

Manual filling: The bag opening is easy to widen, and the stand-up pouch design allows it to stand independently, making it simple for one person to operate.

Semi-automatic filling: Used in conjunction with a bag‑clamping device, it employs gravity or auger feeding, achieving a filling rate of 30–60 bags per hour.

Fully automatic filling line: with standardized bag‑mouth dimensions, it is compatible with gravity‑feed bagging machines and integrates filling and sealing in a single operation.

Sealing method

Top sealing: Options include heat sealing (with the inner liner sealed separately), sewn sealing (single-fold stitching or overlock on the outer bag), or a combined sewn-and-heat-sealed approach (providing excellent moisture resistance).

Bottom sealing: M‑side pouches typically feature heat‑sealed or sewn bottoms, offering high strength and stable upright performance.

Easy-open design: A tear notch or pull-tab seam can be incorporated to facilitate opening by end users.
