Product Specification

To learn more about big bag for mineral and construction:

Mineral big bag is normally used for storage & transportation of Mining and Mineral products such as coal, copper mineral, metal mineral, zinc mineral etc.

These bags are manufactured from polypropylene woven fabrics which are stabilized against UV degradation. Each bulk bag can stand loading capacities between 500kgs to 3000kgs with safety factor of 5:1 or 6:1 (5:1 is for Single use & 6:1 is for multiple use or for UN bags), depending on the bag design and usage. Optional LDPE or HDPE inner liner can be included to provide additional protection against moisture.

This bag can be manufactured for single-use or multiple-use according to specific applications. They are also available with a variety of loading and discharge options. So it is safe and convenient to transport.

Our Advantages:

● In-house Ultrasonic, heat cutting equipment, Metal detector testing machine.

● Light inspection on each bag from Light inspection table.

● 4-side, 4 -colour Printing available and 8-color BOPP colored film available.

● Professional R&D staff to support our technique design..

● Skilled production staff to promise the delivery time.

● Products tested and qualified to international standards.

● Sales & customer service team to give you one-stop support.

● Free sample is available for request.

How to select the suitable bag type for your application?

● Circular or Tubular

Tubular shape bag with seamless made from pp woven fabric on a circular loom.This eliminates the need for vertical seems. Bottom of bag can be square or circle shape.

● U-Panel

U-Panel bags consists of a large “U” piece of fabric with 2 side panels sewing to each side to fulfill a bag shape. U-panel bulk bags can provide the square shape and enlarge the loading capacity.

● 4 Panels

4 Panel bag with 4 separate fabric panels to construct a bag by sewing together. And another square sheet of fabric is used to make the bottom of the bag.

● Baffled bag

Baffled bags are typically 4-panel or U-panel or Circular bags which using internal fabric baffles to keep the bag square shape and stability. These bags are designed to maximize storage and save shipping space.

The conductive big bag is standard used to prevent inflame as electric charge may occur when explosive material rubs with the packaging polypropylene materials during the filling and discharging. These bags will protect the goods not inflect by the electric so as keep safe of human and environment.

Generally, there are two situations that bear danger:

● Explosive Materials - When explosive materials are packed into big bags, the use of conductive big bag depends on the minimum ignition energy of the material.

● Explosive Environment - Dust, gas or steam can cause explosive environment. The danger is highest when the explosive environment consists of gas or steam.

Classification according to the degree of hazard of the cargo material

MIE (minimum ignition energy), mJ (mega Joule)

TYPE A

Type A big bag is made of fabric without any protective function against static electricity accumulation, and can be used to fill, unload and transport non-flammable and non-explosive products. Most of big bags used in the industry are belong to this type..

TYPE B

The Type B big bags are made from low-voltage fabric which has low resistance (6Kv). They are used to fill, unload and transport non-flammable and non-explosive products. They can be used to transport dry and flammable products in powder form.

TYPE C (CONDUCTIVE BIG BAGS)

The C-type big bag is completely conductive. They have black conductive carbon fibers woven into the fabric. In addition, all parts of the bag are connected by conductive interconnects, so the resistance between any part is less than 107 ohms. The Type C big bag has a black ground point, and one of them must be grounded during filling and discharging. Alternatively, some filling and unloading stations can ground Type C through the lifting loops. Using C-type bag can effectively eliminate electrical loads.

TYPE D

The Type D bag is a substitute for the Type C. Due to the Crohmiiq fabric on the bag during the loading and unloading of the product, the accumulated energy can be directly released into the atmosphere without grounding. Make sure that the surface of the type D bag is not in contact with conductive materials such as water and oil.
