Production process

Woven bag production process

1. Introduction

Woven bag is a kind of packaging material widely used in logistics, agriculture, industry and other fields. Because of its durability, lightness and ease of production, woven bags occupy an important position in the market. This article will detail the production process of woven bags to help readers better understand this product.

2. raw material preparation

1. Plastic particles: The main raw material for the production of woven bags is plastic particles, such as polyethylene (PE), polypropylene (PP), etc.

2. Auxiliary materials: add color masterbatch, stabilizer, plasticizer and other auxiliary materials as required.

3. raw material melting and mixing

1. The plastic particles are heated and melted in the extruder to form a molten state.

2. The auxiliary materials are added to the molten plastic and homogenized by mixing to ensure the uniform distribution of the raw materials.

4. weaving process

1. The extruder extrudes the molten plastic into filaments, which are woven in a certain proportion to form a woven cloth.

2. During the weaving process, the weaving density and pattern can be adjusted as needed.

5. printing and processing

1. The woven cloth is printed by the printing machine, and the information such as trademark, text and pattern can be printed.

2. According to the needs of processing, such as cutting, heat sealing, etc., to form the final woven bag shape.

6. Quality Inspection and Packaging

1. Quality inspection of woven bags, including appearance, size, load-bearing and other indicators.

2. Packed by woven bags after testing, generally using cartons or plastic bags for packaging.

Detailed 7. of the specific production process

1. Raw material preparation stage: according to production needs, prepare the corresponding types and colors of plastic particles and auxiliary materials.

2. Raw material melting and mixing: heat the plastic particles in the extruder to a molten state, add auxiliary materials and mix evenly.

3. Weaving process: Extrude molten plastic into filaments and weave into cloth according to a certain proportion. This stage can be adjusted according to the needs of weaving density and pattern.

4. Printing and processing: send the woven cloth to the printing machine for printing, and then process it according to the needs, such as cutting, heat sealing, etc.

5. Quality inspection: the appearance, size, load-bearing and other indicators of woven bags are tested to ensure that the product quality meets the requirements.

6. Packaging: Packed by testing woven bags, usually packed in cartons or plastic bags for storage and transportation.

7. Finished products into the warehouse: put the packaged woven bags into the warehouse and store them in categories for subsequent sales and management.

8. considerations

1. In the production process, attention should be paid to safe operation to avoid accidents.

2. Strict testing of raw materials to ensure that the quality of raw materials meet the requirements.

3. Regularly check the operation of production equipment to ensure the normal operation of equipment.

4. Strengthen quality control to ensure stable product quality.

9. epilogue

The production process of woven bags includes raw material preparation, raw material melting and mixing, weaving process, printing and processing, quality inspection and packaging. In the production process, it is necessary to pay attention to safe operation, raw material testing, equipment inspection and quality control. By optimizing the production process and improving the level of production technology, the quality and production efficiency of woven bags can be further improved to meet market demand.
