Structural Design

Bag Structure

The overall design adopts a cylindrical or square-column shape with a smooth surface free of excess folds. This maximizes internal space utilization, ensures even cargo distribution, and prevents localized stress that could cause damage.

Lifting and Handling Design

The top features 2–4 high-strength polypropylene (PP) woven lifting loops. These loops are attached to the bag body using double-stitched seams and reinforced patches, matching the bag's tensile strength. They allow direct lifting with forklifts, cranes, or similar equipment without additional strapping, ensuring convenient and safe operation.

Unloading Design

The bottom of the PP Woven Bulk Big Ton Bag features multiple discharge port types to accommodate various cargo requirements:

The standard version has a drawstring discharge port. Simply untie the drawstring for quick unloading, suitable for granular or blocky goods.

Product production

Applicable Scenarios

Agricultural Product Storage and Export

PP Woven Bulk Big Ton Bags are ideal for storing and shipping agricultural products, including grains (wheat, rice, corn, soybeans), feed, and cotton.

Construction Waste and Solid Waste Management

In construction projects or environmental initiatives, these bags facilitate the collection and transportation of construction debris or solid waste, including sand, gravel, brick fragments, concrete chunks, and scrap plastic.

Safety Assurance

Load-Bearing and Structural Safety Testing

Before shipment, every batch of PP Woven Bulk Big Ton Bags undergoes rigorous load-bearing and structural strength testing. By simulating actual lifting conditions, we test the tensile strength of both the lifting loops and the bag body. This ensures no tearing or deformation occurs when subjected to 1.5 times the rated load capacity.

Material Quality Control

Only virgin polypropylene resin is used, free from recycled materials or impurities, guaranteeing bag strength and safety. During production, real-time monitoring of woven fabric thickness and density is conducted, while stitching thread quality and stitch density undergo strict control to prevent material-related issues from compromising the ton bag's service life and safety.
