Quality & Factory
Six steps, all in-house
Because we make our own yarn, fabric and webbing, we control the strength of every bag from the raw material up.
Yarn drawing
Virgin PP resin is extruded into film and slit into flat tape yarn on our own drawing lines. Using only new material here is what keeps the fabric strength consistent.
Winding
The tape yarn is wound onto bobbins on take-up machines, ready to load onto loom creels and webbing looms.
Circular weaving
Circular looms weave the yarn into tubular PP fabric, the body of every bag. Double-warp fabric is woven for bags that need a stronger body.
Webbing (lifting loops)
Webbing looms weave the belts used for lifting loops and reinforcement straps. Widened, thickened straps are the foundation of a bag’s load-bearing strength.
Coating
Fabric for waterproof and moisture-resistant bags is coated (laminated) on our coating line. Uncoated fabric is used where the product needs to breathe.
Cutting & sewing
Fabric is cut in the cutting workshop and sewn into bags with lifting loops, spouts and anti-leak strips. Lock-edge seams and double stitching keep seams from opening or skipping.

Applications
Bags matched to what you pack
Powders, granules and lumps behave differently in a bag. We recommend the structure from your product and handling, not from a catalogue.

Common questions
What is an FIBC ton bag?
An FIBC (flexible intermediate bulk container), also called a ton bag, jumbo bag or bulk bag, is a large woven polypropylene bag with lifting loops, used to store and move powders, granules and lumps in units of around one tonne. Mingzhe makes 1-ton and 2-ton types and custom designs.
How much weight can a bag carry?
Our range covers 1-ton and 2-ton bags. The rated load (safe working load) depends on fabric, loops and construction, so we confirm it with each specification; test details are available on request.
Which top and bottom should I choose?
Choose the top by how you fill: open or skirt top for shovel and grab loading, a filling spout for filling heads and low dust. Choose the bottom by how you empty: flat bottom when you cut or tip the bag, a discharge spout for controlled discharge, a conical bottom for products that bridge or clump.
What is your MOQ, lead time and price?
They depend on the specification and quantity, so we quote them per enquiry. Send the details listed in our quote guide and we will reply with all three.
