Design
The first step in the manufacturing process is to design the bag to meet the specific requirements of the customer. This includes determining the size, shape, weight capacity, and features such as lift loops and discharge spouts.
Material Sourcing
Once the design is complete, the next step is to source the materials needed for the bag. This includes the woven polypropylene fabric for the body of the bag and the stitching thread.
Cutting
The next step is to cut the woven fabric into the correct size and shape for each bag. This is typically done using specialized cutting machines that are designed to handle large rolls of fabric.
Sewing
After cutting, the edges of the fabric are sewn together to create the body of the bag. This is usually done using specialized sewing machines that are designed to handle heavy-duty materials.
Quality Control
Once the sewing is complete, the bags undergo a thorough quality control process to ensure they meet the desired specifications. This includes checking for any flaws in the fabric, ensuring the correct weight capacity, and verifying that the lift loops and discharge spouts are securely attached.
Packaging and Shipping
Finally, the finished bags are packaged and shipped to the customer.
