The quality of the woven bag is inseparable from the weight of the gram. Generally speaking, the higher the weight, the thicker the bag, the better the quality. The measure is in weight. The base bag of the bulk bags is calculated by the square meter, which is generally 160 grams per square, 180 grams, 190 grams, 200 grams per square. If you cut the piece down, measure the size, and then weigh the weight, you can calculate the square of the square of the square. The weight of the woven bag directly determines the thickness of the woven bag. The calculation formula is as follows: single bag weight = length * width * 2 * square gram weight.
For example, thickness 60 microns, size 180 * 270cm
weight is volume * density, volume 0.006 * 180 * 2 * 270 = 583.2 density
PE is 0.917
583.2 * 0.917 = 531.2952 grams
There are relatively cumbersome calculation method: (number of latitudes) /2000.911=square gram weight

The above is the calculation method of the gram weight of the base fabric.
There is no certain calculation method for the bulk bags, because the bulk bags has more accessories, it has to be decomposed one by one. , one by one, and finally added together. (Generally, the composition of the bulk bags; the main body, the sling, the upper cover, the bottom, the upper and lower feeding ports, the ties, the closing rope, the file bag, the label, the reinforced cloth, etc.) and the base cloth to be determined by the different quality to be loaded The weight of the sling is not the same.

Ultraviolet-resistant baffle bags, i.e. ultraviolet-resistant container bags, are used for the storage and transportation of chemical products. They are designed by the characteristics of chemical raw materials. In addition to carrying capacity and other requirements, they generally need to ensure the integrity and safety of their packaging items and meet the requirements of the corresponding packaging materials.

The security of baffle bags is the first consideration. Packing volume, loading weight and a number of packing units should be considered in the design. The distance of transportation and the number of times of handling should also be considered. What kind of transportation means and methods should be adopted?

The sealing performance of baffle bags is different from that of consumers, so we should take full account of it. For example, powder or poisonous substances, and objects afraid of contamination require very strict sealing performance, and materials prone to dampness or mildew also have special requirements for air tightness.

Baffle bags are mainly used in bulk, granular or powdery articles, and the physical density and lose a degree of contents have different effects on the use.

The performance of baffle bags should be tested as close as possible to the products loaded by customers. This is the “standard filling material for testing” written in the standard, so as to meet the challenges of the market economy as far as possible by technical standards.

What role can anti-ultraviolet baffle bags play?

  1. Packaging restrictions of container bag manufacturers are very large. Powdery products can be packed in bulk bags.
  2. Increased loading and unloading power. It has a large capacity, very fast loading and unloading, more than ten times the efficiency of conventional paper bag packaging.
  3. Can effectively maintain the product. Container bag material has the function of rainproof and impermeability. It can also be dampproof when it is filled and placed outdoors.
  4. Less space. The empty bag is foldable and small in size. The round baffle bags have a large capacity.
  5. Long life, anti-ultraviolet baffle bags tons, can be used repeatedly. Baffle bags are made from highly intensive data that are durable and can be accepted for reuse.

The normal size of a ton bag is Dimensions of 100 * 100 * 100 or 95 * 95 * 100 or 90 * 90 * 120 (in cm) are commonly used.

Inch is 39.37*39.37*39.37 or 37.40*37.40*39.37 or 35.43*35.43*47.24

Conventional 1 cubic, 1 ton bags are the bags below.

The bulk bag material is generally made of polypropylene PP; which is mainly divided into, new PP material, PP back to the material, powder, etc.

The price of bulk bag is generally calculated as the standard weight of the bulk bag itself; according to the design out of

The bulk bag dimensions, calculate the corresponding weight ratio; come to the price per gram weight to be calculated.

PP container bag depends mainly on what kind of material, new material, recycled material, or blended part of the recycled material.
The price is different. Now the material price has gone up a little. It depends on your material is not brand-new material and the workmanship is not very complicated.

Precautionary measures:

1) in the rising work does not stand under the bag of the congregation.

2) Please hang the hook in the central part of the sling or rope, do not hang, hang on one side or tilt hanging bag.

3) Work does not rub with other parts, hook or collision bags.

4) Do not pull lanyards to the outer reverse.

5) when bagging when using the forklift work, please do not make the plugin contact with or bind to the body of the bag, in order to prevent tying the broken assembly bag.

6) In the workshop when handling, try using a tray, avoid with a hanging hook putting in bags, shake the side of the side when adjusting.

7) in loading, unloading and stacking to keep the assembly bag upright.

8) Do not lay the bag in an upright position.

9) Do not drag the bag on the ground or concrete.

10) in case of need for external storage, the bag should be placed on the shelf and should be securely covered with opaque fabric.

11) after use, with a paper or an opaque bag deposited in a ventilated place.

As we all know, suspension belt (also known as suspension rope) is one of the most important standards to measure the performance and quality of bulk bags products. The load-bearing capacity of the suspension belt directly affects the quality and safety of products. So how to test the load-bearing capacity of bulk bags suspension belt and suspension rope? Hebei Wanhefeng Packaging Co., Ltd. explains the following test methods for the load-bearing performance test of space bag sling and suspension rope test methods, hoping to be useful to you:

  1. Sampling method

At least two suspension band specimens of appropriate length are randomly intercepted at bulk bags suspension rings.

  1. Elongation test

The specimens are mounted on a tensile testing machine. After applying a 196N tightening load, a 100 mm distance marking line is drawn. When the load reaches 30% of the tensile strength f, the distance between the marking lines is measured.

Elongation (%)=[(l-100)/100]*100%

“L” means the distance between the lines, mm, when the load reaches 30% of the tensile strength.

  1. Tensile Strength Test

The specimens were fixed on the fixture of a tension tester with a distance of 220 mm. Tensile strength was measured at a speed of about 100 mm/min.

Above are three steps of bulk bags sling and sling test. Without sampling, the overall quality of the product cannot be reflected. The elongation test is very important for lifting operation, and the tensile strength affects the safety of operators when lifting.
