Standard FIBC

Standard FIBC , though does not necessarily have a standard size or dimension, are structurally flexible. These bags tend to bulge out along the middle when filled. Thus, these standard FIBCs somewhat assume the shape of a pear after being loaded, making it inconvenient to stack up in storage or during transportation.

Standard FIBC is a large bag made of flexible woven fabric, designed for storing and transporting dry, flowable products, such as sand, fertilizers, and grains. It usually consists of four lifting loops, a filling spout at the top, and a discharge spout at the bottom, making it easy to fill and empty the bag.

To precisely estimate the size of bulk totes that you require, you should examine the following factors depending on Standard FIBC;
The product density is packaged in the bulk storage bag (each product has a specific weight).

You must choose the bulk bag/ one ton bag dimensions according to the specifications of your filling equipment to fill and discharge the large sack.

The vehicle’s width, length, and height that will transport the industrial tote bags (truck, container or train wagon, ship) are critical in determining the dimensions of the FIBC. Additionally, the dimensions of the shelves and the company of the warehouse space in which the big bags will be stacking are critical.

Standard FIBC are typically considerably large than other forms of storage, such as cardboard boxes. Thus, it is critical to consider how the bigger size of these containers affects their total weight and how they must be stored. In addition, since Standard FIBC can keep up to two tons (4,000 pounds) of material, lifting and moving them frequently requires specialized equipment. Generally, the bags should be stored on pallets to keep them off the floor and facilitate their movement.

Depending on the items and materials placed in the Standard FIBC, you will have to evaluate the pallets you employ and whether they are robust enough to support the additional weight of the Standard FIBC. A pallet of typical size will hold a 35-inch square Standard FIBC. However, depending on the material of the bag, it may fall over the sides of the pallet, impairing your ability to store and transfer the bag and pallet simply and safely. When empty, the bags are rectangular, but they often take on a more cylindrical appearance once filled.

When considering the production process for Standard FIBC, it consists of many phases, irrespective of the design or customer requirements. Laminating treatment is ideal for increasing the moisture barrier for items that require a low moisture transfer rate. However, it is essential to weave and cut the fabric before the bag building begins.

Extrusion

The initial stage is extrusion, which melts a mixture of virgin components and forms tapes of specific measures. This procedure utilizes polypropylene (PP) granules, a trace amount of calcium carbonate, UV inhibitors, and maybe color pigments. The assessment of the durability of the tapes is pretty necessary at this point. Then, during the preparation for the weaving step, it is necessary to load the tapes onto industrial bobbins.

Weaving

On weaving looms are loaded the tapes made by PP granules. In this case, the polypropylene fabric that makes up the body is woven into shape for a bulk bag. The material is sufficiently sturdy to convey a wide range of industrial goods and consumables. It is “breathable,” though, and hence vulnerable to moisture transition. The woven PP material is also utilized for loading and unloading components and the material for Standard FIBC.

Moisture

By coating the fabric with a special lamination, it is possible to make each bag humidity resistant. But, this totally depends on the customer’s demands. Lamination is the technique that is perfect for the humidity resistance of Standard FIBC. Moreover, moisture proofing is essential for Standard FIBC that carry granular items and for any product that should not be exposed to humidity.

The un-laminated material of polypropylene comprises small strands with microscopic pores in each fabric. The material is essentially breathable. The transport and storage of diverse materials can be acceptable quality, however not suitable for selected products. For example, sugar and salt, including water absorbed in the air, should never be exposed to water.

Cutting

Firstly, the polypropylene fabric is placed into a slicing machine and cut into precise shapes. The dimensions are determined by whether the process produces sides, edges, or bottoms. Automatic measuring assures exact lengths for each cut. Whether the bulk bag line is square, tubular, or vertically rectangular, the necessary cuts are made at this phase.

Printing

After cutting the polypropylene fabric into shape, it is passed into a printing machine. Imprints are made on the fabric here. Printing happens at this phase if a corporation wishes to apply the brand name or logo to a line of bags. Depending on the brand, a variety of colors may be used. A heavy-duty printer is required for this method to produce the best impressions possible.
