3001 Onion Raschel Mesh Bag

The jacquard machine mesh bag is a high-strength, breathable mesh structure packaging bag produced by using double-needle bed jacquard weaving technology. It is widely applied in agricultural products, industrial and other fields. Its core advantages lie in the seamless forming process, efficient production and strong customization capabilities. The following provides a systematic introduction from the aspects of process characteristics, equipment technology, application scenarios and purchase considerations:

I. Core Process Characteristics

1. Seamless One-Time Forming

Seamless weaving: Through double-needle bed tongue needles or composite needles for high-speed weaving, an even mesh is formed, eliminating the need for sewing the side edges, thus avoiding the risk of tear at the seams in traditional woven bags.

Automatic completion of processes such as weaving ribs, edge locking, and string threading reduces manual intervention and increases production efficiency by over 50%.

2. Ventilation and Lightweight Design

The mesh size can be adjusted flexibly (ranging from 1×1mm to 10×10mm). For example, the onion bag commonly uses 8×8mm mesh size, which balances the visibility of the contents with ventilation, reducing the spoilage rate of fruits and vegetables by 30%.

The weight range is 11–100g/㎡, which is 30% lighter than traditional film packaging, thereby reducing raw material costs.

3. Efficient and Energy-Efficient Production

The spindle speed ranges from 200 to 700 revolutions per minute (supports variable frequency speed control). For high-speed models (such as Kallmeyer RS2NK), it can reach 1200 rpm, with daily output exceeding 10,000 meters.

The energy consumption is low, with the power consumption per unit output being only 50% of that of a warping loom.

4. Material Adaptability

The raw materials include PP (polypropylene), HDPE (high-density polyethylene) flat wires, as well as polyester and nylon monofilaments. They offer both high tensile strength (capable of supporting up to 100kg) and corrosion resistance.

II. Production Equipment and Technical Parameters

Typical Equipment Configuration (Taking GE2818 as an Example)

III. Application Scenarios and Industry Solutions

1. Agricultural Product Packaging

Root and stem vegetables: Onions, potatoes, etc. are packed in 8×8mm mesh bags, which allow air circulation and prevent mold and spoilage, replacing shrink films to reduce spoilage rates.

Fruit transportation: Citrus fruits, apples are packed in mesh bags to reduce crushing damage and the lightweight design reduces logistics costs.

2. Aquaculture and Industrial Sectors

Live Transport: Shellfish and live fish are transported in mesh bags that allow water to pass through and provide oxygen, reducing the mortality rate during transportation.

Engineering Materials: Mesh bags with high weight (100g/㎡) are used to hold sand, gravel, and mineral ores, and are employed in slope protection and sand fixation projects.

3. Derivative Applications

Sunshade net/soil covering net: By changing the raw material (such as black HDPE flat wire), agricultural nets with a shading rate of 50% - 95% can be produced.

Bundling net for hay: The efficiency of hay bundling is increased by 50%, and it is easy to untie.

IV. Purchase Suggestions and Customization Services

1. Equipment Selection Basis

Production Scale: For small batches, choose narrow-width machines (such as JBZ170, with a width of 4500mm); for large batches, choose wide-width machines (such as JBZ270, with a width of 6800mm).

Functional Requirements: For rapid flower pattern changes, select electronic jacquard machines (such as KARMAYE RDS 11 EL); for heavy packaging, select interwoven weaving + high-weight configuration.

2. Customization Options

Mesh size and weight: For fine packaging (nuts), use 1-3mm small mesh; for sandstone bags, the weight should be ≥ 100g/㎡.

Post-processing techniques: The bag opening can be customized with stringing, heat sealing, or bottom sewing; the surface supports color printing labels.

3. Ancillary Equipment

It is recommended to combine with the flat wire drawing machine and the winding machine to form a production line, enabling the integrated production of raw materials to finished products.

Summary

The jacquard machine mesh bags, with their seamless structure, high-efficiency ventilation and strong customization capabilities, have become an innovative choice for agricultural and industrial packaging. The core value lies in:

Process innovation: Double-needle bed jacquard weaving realizes "bags as finished products", eliminating the need for sewing;

Scene adaptability: From fruit and vegetable preservation to engineering slope protection, the machine can be used in multiple scenarios with strong versatility;

Cost advantage: Lightweight + low-energy consumption design, with a comprehensive cost lower than traditional circular weaving equipment.
