Big bags are packaging, containers in which you can transport anything. Most often, big bags are used for packing, as well as the collection of construction waste. Such a container is used mainly in Europe, while in Russia polypropylene bags are preferred. However, many plants and manufactures preferred big-bags.
What is it?
Big bags are innovative packaging, a bag for packing and transportation. They are large in volume, equipped with special loops so that you can load and unload contents. The material of which the bags are made is moisture resistant, chemically inert, ensures the safety of the cargo during transportation. The bags are soft, so they are used to store and move sand, cement, fertilizers, plastic. Universal packaging, therefore, can be used in various industries and industries. In addition to bulk cargo, bags are filled with lumpy and granular materials with sharp edges.
What are they for?
Building bags are used for storage and transportation of goods (sand, cement, gravel) from construction sites, but not only. Big bags are also used for transporting grain, animal feed in the agricultural industry; flour, sugar, cereals, salt in food; chemical reagents, polymers, plastic, fertilizers in the chemical industry. The high popularity of big bags is due to the fact that this container is the most reliable, durable. It protects the contents from moisture, precipitation, contact with other surfaces. At the stage of packaging and transportation, the loss of bulk is significantly reduced. Glue, balls for bearings, clay, iron ore, and various loose are also transported in soft containers. The bag can withstand up to fourteen tons, but it all depends on the density of the material and layers.
Characteristic
Big bags can be made in the form of a soft bag or with a rigid frame. They are classified not only by their appearance and purpose, but also by the term of operation: for single and multiple use. Recycled containers are also produced, which are used in several transport cycles. Bags are also available for bulk and liquid products. They characterize big-run on load-bearing elements: one-, two- and four-line. Containers can have a lapel, an apron, a valve. Initially, big bags are designed for long-term use. These are reusable products that pay off their value.
Soft containers are shockproof, retain their shape, prevent the occurrence of mold, their surface prevents slipping, and a minimum of static electricity is formed. In addition, such bags can be made to order, both with handles and without them. The advantage of big bags is that this soft container prevents rotting inside the bag. This is true for food manufacturers, as well as for agricultural. Sometimes the inner surface of the bags is lined with foil. To create big bags use nylon, polypropylene, polyamide, as these materials are the most durable and wear-resistant.
Features
Big bags are universal. Their main advantage is reusable use. Thanks to this, packaging costs are reduced, and the transportation process is facilitated. The peculiarity is that these soft bags are most adapted for loading and unloading equipment, taking into account its design. Big bags are an economical type of packaging designed for multi-ton cargo. It is considered the most reliable. These bags are distinguished from other designs by carrying capacity, capacity, type of slings, presence of hatches, covers, assemblies, density of material, layers. They withstand both low and high temperatures.
The bag is able to withstand huge loads, it all depends on its volume and density of the material. A container is made of kapron (outer shell) and polypropylene (inner part). It is the latter that contacts the content. Transported products are well protected. Bags are produced with a blank bottom, a lower hatch, as well as an open top, with lids, assemblies, drawn in laces.
Types
Big-bag construction bags can be single, double or quadruple. A double-line bag is the most economical and demanded among other types. Its construction is solid. It is a big-run strong and roomy container with two lifting components, that is, slings. This is a continuation of the bag itself. Use a double-line design in the food, chemical industry, construction, agriculture. Often it is used for transportation and storage of sand, cement, lime, sulfur, various mixtures. Slings for reliability are tied with laminated polypropylene. They make such bags with loading hatches.
Four-line big-bags are a universal container which is used everywhere. The containers are soft, different in volume, carrying capacity, shape. They can be supplemented with slings, a hatch, assemblies, that is, adapted for a specific production. Most often used bag in food, chemical industry, agriculture, construction. Packing in big bags is not difficult, it is as comfortable as possible. They load grain, compound feed, sand, cement, and other bulk ones.
Prices
The cost of this soft container depends on the size and capacity. If you buy in bulk, the price will be lower. For example, big-bags measuring 75 × 75 × 120 cm cost 250 rubles per 1 piece, and are sold in packages of 10 pieces. Bags 150 × 125 cm - 2 slings, density 145 g / m2, price for 1 bag - 187 rubles, sold in packages of 100 pieces. As you can see, big bags are expensive, but they also have a special purpose: transportation of goods over long distances.
