\"Big<\/a>What are Big Bags?<\/h2>\n

Big Bags<\/strong> (also called sacas<\/em> in Spain) are industrial containers made mainly of flexible plastic fabric that have revolutionized the temporary storage and transport of dry bulk products market, due to their high resistance, malleability, and versatility.<\/p>\n

With a typical capacity of one tonne, maybe more, the Big Bags<\/strong> are ideal for managing debris<\/a><\/span><\/strong>, soil<\/a><\/span><\/strong>, aggregate transport<\/a><\/span><\/strong>, fertilizers<\/strong><\/span>, compost<\/span><\/strong><\/a>, etc.<\/p>\n

Big Bags: An optimal product<\/h2>\n

Big Bags <\/strong>have excellent recycling<\/a><\/span><\/strong> and reconditioning characteristics and allow you to save space when storing your products, as they take up very little volume when empty and weigh very little compared to other types of containers. A Big Bag<\/strong> capable of holding and lifting a tonne can weigh as little as 700 grams sometimes.<\/p>\n

Big Bags of all kinds<\/h2>\n

Standard Big Bags<\/a><\/span><\/strong> are usually 90 x 90 x 100 cm of white PP fabric with 4 handles for 1,000 kg (FS 5:1). In any case, there are thousands of variations combining the different options of configuration, measures, resistance, fabrics and additional components that allow the fabrication of Big Bags<\/strong> absolutely customized and suitable for the required use in any sector: aggregates, soil, rubble, grass and all types of bulk, food, chemical products, fertilizers, firewood, etc.<\/p>\n

It is possible to make them by combining any of the values and possibilities of the following characteristics:<\/p>\n<\/div>

Big Bags Configuation<\/h2>\n

The configuration of a Big Bag is the composition of different elements that may form it (lids, bottoms, filling and discharging spouts, inner liners, inner reinforcements, openings, closures, pockets, labels, ties, etc.), their shape and arrangement. All this must facilitate its handling during loading, transport, and unloading, as well as ensure the integrity of the product it contains, the personnel who handle it, and the environment.<\/span><\/p>\n

Basic configurations:\"\"<\/a><\/p>\n

1<\/span> Open top and flat bottom<\/a><\/span><\/strong>
\n 2<\/span> Mouth top skirt and flat bottom<\/a><\/span><\/strong>
\n 3<\/span> Mouth with top flap and flat bottom<\/a><\/span><\/strong>
\n 4<\/span> Charge spout and flat bottom<\/a><\/span><\/strong>
\n 5<\/span> Mouth top skirt and discharge spout<\/a><\/span><\/strong>
\n 6<\/span> Charge spout and discharge spout<\/a><\/span><\/strong>
\n 7<\/span> Open top and discharge spout<\/a><\/span><\/strong>
\n 8<\/span> Open top and bottom of diaper<\/a><\/span><\/strong><\/p>\n<\/div>

Big Bags Sizes<\/h2>\n

\"Big<\/a>The standard dimensions of a Big Bag are usually 90 X 90 X 100 cm (W x B x H). All Big Bag dimensions are customizable and must be adapted to the volume to be contained and transported. There are Big Bags as small as to hold only a pot for one or two small plants of a few centimeters, and Big Bags as large as a 40-foot container that can hold several cubic meters with many tons of bulk products.<\/p>\n

For the same Big Bag of 90 cm x 90 cm at its base, for example, the following heights can be supplied as a guideline: 60 cm \/ 80 cm \/ 90 cm \/ 100 cm \/ 120 cm \/ 140 cm \/ 150 cm \/ 160 cm \/ 170 cm \/ 190 cm \/ 210 cm<\/p>\n

All other Big Bag components such as handle heights, spout diameters, labels, and document holders are also customizable under minimum order conditions.<\/p>\n<\/div>

Handles on Big Bags<\/h2>\n

There are also different options for handles depending on the method or machinery for handling and transport. They are mainly available with 1 handle, 2 handles, 4 handles, and 4 cross-corner handles, although other options are available.<\/p>\n

Some Big Bags of low maximum authorized weight incorporate additional handles on the base to facilitate their decanting.<\/p>\n

Other Big Bags have 2 horizontal cylinders on the top for the insertion of the forks of the forklift trucks.<\/p>\n

Colors, lengths, thicknesses, strengths, materials, and other features are also customizable elements for the handles.<\/p>\n<\/div>

Maximum authorized weight and safety factor of Big Bags<\/h2>\n

\"Load<\/a>The Safe Working Load<\/em> (SWL) and the Safety Factor <\/em> (SF) are among the most important characteristics of a Big Bag. They establish the maximum load a Big Bag must be subjected to. It must not exceed the maximum load under any circumstances. To avoid breakage and possible accidents, despite the definition and proper labeling in a visible place of this maximum weight, the Big Bag must be made in a way that it supports N times its maximum working weight, this ratio N:1 being known as the safety factor. A Big Bag with a maximum working weight of 1,000 kg and a safety factor of 5:1 should not break provided it is properly handled up to 5,000 kg of load. Nevertheless, the maximum load weight must never be exceeded.<\/p>\n

All Multisac Big Bags are subjected to strict resistance tests that ensure compliance with their specifications in terms of maximum working weight.<\/p>\n

The standard maximum working weight for most Big Bags is 1,000 kg with a 5:1 safety factor, although it is also possible to manufacture Big Bags for 500, 1,500, or 2,000 kg with safety factors of 3:1 or 6:1, among others.<\/p>\n<\/div>

Big Bags Fabrics<\/h2>\n

\"Woven<\/a>The type of fabric and construction with which the Big Bag is made is another of its characteristics. The most common is polypropylene (PP) woven fabric, typically white. Normal, high-density, ventilated, or open-mesh finishes can be obtained depending on the fabric manufacturing.<\/p>\n

There are other types of fabrics and special finishes such as monofilament or different types of conductive fabrics.<\/p>\n

All of them are suitable for storing certain products that may require different degrees of impermeability, humidity, visibility, or breathability.<\/p>\n<\/div>

Inner bags and coatings of Big Bags<\/h2>\n

\"Big<\/a>Sometimes additional layers are required for proper storage of the product. Big Bags can be supplied with inner bags or inner liners, usually made of high or low-density polyethylene (PE), although other options such as aluminum bags are also available.<\/p>\n

The bags can be placed inside the Big Bag or glued to the inside walls of the Big Bag and\/or sewn along its upper contour at the mouth.<\/p>\n

On the other hand, the PP woven fabric of the Big Bag can be optionally or additionally supplied coated with a polyethylene outer layer, thus further protecting the contents from the outside.<\/p>\n<\/div>

Printing and labeling of Big Bags<\/h2>\n

\"Big<\/a>Big Bags can be customized with different types of printing from single color printing to photographic quality image printing on any or all sides.<\/p>\n

In addition to the recommended labels with instructions for the proper use and handling of the Big Bag itself, information about the manufacturer of the product to be contained or information about its characteristics may be included on the same or additional labels.<\/p>\n<\/div><\/div>
