Bulk bags are different from ordinary plastic woven bags. Because its carrying capacity is much larger than ordinary packaging materials, the stitching of each part of the bag is also crucial. Unlike ordinary plastic bags, which are just like simple heat sealing, they need to be combined with other parts through multiple processes.

Bulk bags

This goal is the most important and crucial goal of bulk bags. In GB / t8946 and GB / t8947, the tensile load in the direction of the seam edge and seam bottom is clarified. The main factors that affect the suture strength are the type and type of suture, the size of needle pitch, suture trace, the scale from crimped or folded suture to the bag edge, the hot and cold cutting methods, etc.

Generally speaking, sacs en vrac production companies should formulate the internal control objectives of these influencing factors. As for bulk bags, according to the national regulations, it is necessary for the tensile strength of the main joint to reach more than 67% of the basic strength, and the tensile strength of the bottom joint to reach more than 42% of the basic strength. As for the upper sealing of the spigot cement bag, it is proposed to treat it as the bottom strength of the seam. As for the bottom strength of the paper bag, it is usually unable to achieve the goal, so it is proposed to change it into the paste bottom bag. As for the cold cut bag of laminating film, it is suggested to use curling treatment, because the future of the cold cut edge may be torn out from the warp and weft. As for the upper edge of the woven bag without strength requirement, the stitch distance can be tight and the thread can be thin.

More knowledge about bulk bags can be consulted with us. Bulk bags manufacturers are welcome to order bulk bags and ton bags.

Bulk bags is a tool used to hold the material, it can be difficult to transport such as powder particles and other materials for packaging, easy loading and unloading, and storage. Thus, the quality of such products is more important, in good condition it can be a good completion of the corresponding work. But users will find that sometimes the bag suddenly cut off, this is because what?

there are many reasons for the bulk bags off, the main reason is caused by the environment and use. First, the environment, into the winter temperature drops rapidly, many objects will be affected because of the low-temperature weather, brittle and fragile. The bag will also be the case, when the temperature is low, the bag material becomes brittle and hard, no normal patience, in this state bloom too much material may be due to excessive force appeared fracture.

The use of sacs en vrac from the loading, loading, transportation, unloading, storage and other processes may be subject to varying degrees of wear, or scratches, so the connection strength between the material is not high, in the use of force will be broken.

Therefore, for long-term use of the product should be promptly checked to exclude serious wear of the bag.

Bulk bags are used in many industries for the transport of products is very convenient. But in the use of time should also pay attention to it to do a good job of dust and moisture measures, so as to ensure the safety of Transportation Products.

In the transport is very vulnerable to the weather and the natural environment, always encounter dust and moist air, but many products need to do the work of dust and moisture. sacs en vrac of the material itself is good moisture, dust, radiation resistance, strong security features, in the transport of goods can be easily handling and handling, improve work efficiency, is currently using more transport packaging. Of course, in addition, we should use anti-rain tarpaulin and other products to do a good job of protective measures, bulk bags storage environment and put the requirements should also have certain rules, so you can well avoid being affected.

Let’s talk about the materials used in the production of the sacs en vrac in detail, as well as the physical properties and general chemical properties of various materials. Thank you.

What is the material of the bulk bag?

Two materials, polypropylene, polyethylene, polypropylene is a thermoplastic resin made by polymerization of propylene

Polypropylene is a non-toxic, odorless and tasteless milky white high crystalline polymer with a density of only 0.90 — “0.91g/cm3. It is one of the lightest plastics at present.

Polypropylene has good heat resistance. The products can be sterilized at a temperature above 100 ℃ and will not deform at 150 ℃ without external force. Due to the large shrinkage rate (1% ~ 2.5%), thick wall products are easy to sag, and it is difficult to meet the requirements for some parts with high dimensional accuracy and good surface gloss. It is very stable for water. Its water absorption is only 0.01%, and its molecular weight is about 80.15 million.

Polyethylene is generally a thermoplastic resin made of ethylene by polymerization.

Polyethylene is odorless, non-toxic, waxy and has excellent low-temperature resistance (the minimum operating temperature can reach – 100 ~ – 70 ° C). High-density polyethylene (HDPE) is commonly known as low-pressure polyethylene. Compared with LDPE and LLDPE, it has higher temperature resistance, oil resistance, steam permeability resistance and environmental stress cracking resistance. In addition, it has good electrical insulation, impact resistance, and cold resistance

Processing technology

Generally, these two kinds of raw material particles or powder are purchased in the production of the sacs en vrac. They are heated and stirred in the factory formula, drawn and shaped, then cut into the required raw silk, and then spun into the required or commonly used bulk bag base cloth by using a circular loom for standby

If you customize bulk bags, you can cut and sew these textiles forming base cloth into various specifications of the bulk bags. Generally, most of them are made of polypropylene. Occasionally, high-pressure polyethylene is used by companies that produce plastics or raw materials. The outer edge of bulk bag is generally coated with low-pressure polyethylene film to achieve the purpose of waterproof, so the basic material of the bulk bag is For those with these materials, it is generally necessary to add some other auxiliary materials to the ingredients in the production process.

Bulk bags are usually made of polyester fibers such as polypropylene and filler. They can be used in a wide variety of industries and are ideal for storage and transportation. So what are the significant advantages of sacs en vrac? Today we will learn about his polypropylene material.
Polypropylene non-toxic and tasteless, low density, strength, and hardness than low-pressure polyethylene. It can be used at around 100 degrees. It has good electrical properties, high-frequency insulation is not affected by moisture.

It is because of the manufacturing materials of bulk bags has the above advantages, so it has the advantages of moisture, dust, strong, safe.

bulk bags are several types of hazardous packaging

bulk bags itself is not dangerous goods, so he is not what several categories of dangerous packing, usually said several categories of dangerous goods, sacs en vrac inside the things belonging to several categories of dangerous goods.

Bulk bags is a plastic tube cloth, packaging, the raw material is polyethylene, polypropylene, and other chemical raw materials, bulk bags are polypropylene resin as the main raw material, extruded, stretched into flat yarn, and then by weaving, a bag made. Here we introduce the bulk bags tube cloth material characteristics.
sacs en vrac

bulk bags cartridge production is mainly polypropylene. Polypropylene is a thermoplastic resin obtained by polymerization of propylene.

Polypropylene raw material

Mainly used for all kinds of long and short polypropylene fiber production, used in the production of polypropylene bulk bags, packing bags, injection molding products for the production of electrical appliances, telecommunications, lighting, lighting equipment, and TV flame retardant parts.

Polypropylene bulk bags

Polypropylene has a lot of properties.：

1, Strong elongation

Polypropylene high strength, elongation, high initial modulus, excellent elasticity. Therefore, polypropylene wears resistance. In addition, the wet strength of polypropylene is basically equal to dry strength, so it is the ideal material for the production of fishing nets, cables.

2, hygroscopicity and staining

Light and warm good, almost no moisture absorption, but the wicking ability are very strong, the wicking effect is obvious; polypropylene hygroscopicity is very small, the moisture regains in general atmospheric conditions close to zero. But it has a wicking effect, through the capillary transfer of water vapor in the fabric, but itself can not afford any absorption. Polypropylene staining is poor, incomplete chromatography, but can be used to compensate for the lack of liquid coloring method.

When bulk bag and sling are connected, there will be many forms in the future, and the connection mode is also special. So, what is the process of connection? The detailed analysis of bulk bag manufacturers is as follows:

When the sling is connected with the bag body, there are various forms such as top lifting, bottom lifting, side lifting, etc. and they are connected by suture, so the future is also very important. Only with the high strength of sling, the base cloth and suture can not reach a certain strength, nor can they ensure the overall high performance of the bulk bag.

Bulk bag mainly contains massive, granular or powdery objects, and the physical density and lose a degree of the contents have different effects on the overall results.

As for the basis for judging the performance of the sacs en vrac, it is necessary to test the product close to the customer’s load as much as possible. This is the “standard filler specially used for testing” written in the standard, so as to make the technical standard meet the challenge of the market economy as much as possible.

Generally speaking, there is no problem with the bulk bag through a lifting test. There are only two situations when the bags fall down in the hoisting of the port, railway, and truck: one is the operation is wrong, and the other is that this kind of bulk bag fails to pass the hoisting test.

For a bulk bag with a safety factor of more than 5 times, two or one of the four rings must have the tensile performance of more than twice and a half of rated load. Even if two slings are disconnected, the whole bulk bag will not have problems.

Bulk bag products are widely used, especially for packing bulk cement, grain, chemical raw materials, feed, starch, minerals and other powder, granular objects, even dangerous goods such as calcium carbide, which are very convenient for loading, unloading, transportation, and storage.

At present, bulk bag products are in the rising stage of development, especially the bulk bag in the form of one ton and one pallet (one pallet for one bulk bag, or four), which is more popular.
