As a buyer, before buying a bulk bags, ordinary to know a few effects: have you used this product before.Assuming useful, then the packaging can be suitable for my product.
Assuming it is appropriate, then it is very complex,you just need to understand the size of my previously used tons of bags, for example, length, width, height are more, perhaps round bulk bags, diameter and height is how much.There is no film, is a single layer or a double layer, bulk bags can have a discharge port, the center of the inlet is a large opening or a small mouth, Sling is two or four hanging hanging, hanging or pocket bottom.

These have to figure out, assuming that there is a printed bag, printed content do not make a mistake, or printed up and then change there is no way.Another important point, assuming that you can not provide samples to manufacturers quotes and consumption, it is possible to inform consumer manufacturers, bulk bags bag weight is how much, so that manufacturers can be based on the weight of the bag you provide, to calculate how thick fabric to help you consume.

Assume that you can provide photos to manufacturers, it will be more intuitive, experienced consumer manufacturers, see the picture, you can know about bulk bags material and bag weight.

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, 散装袋 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 散装袋 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. 散装袋 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.

The key reason for the broken edge of bulk bag sling is that the quality of sling is very poor. If it can’t stand too long-term application, it will break or break the edge, resulting in the problem that the overall container bag can’t be used.

Generally speaking, there are three reasons for the broken edge of sling:
A. excessive and frequent application and continuous lifting damage make the sling exceed the service life, and the similar container bags have already exceeded the service life or frequency, so new ones should be purchased.

B. the most important factor for the sling to rot is the poor quality of the sling made by the manufacturer. It can only be used once or twice. The bulk bag sling is rotten, but the overall body is not damaged. If it has the ability to repair, it can be removed and replaced.

C. another key element is that if incorrect materials are used to make a sling, it is the key problem that causes the broken edge of the bulk bag. If too much polypropylene is used and too little high-pressure polyethylene is used, it will cause the weathering layer. Because the container bag is often used outdoors, the broken edge is inevitable. If such a situation occurs, replace the manufacturer as soon as possible.

让我们详细讨论一下生产所用的材料 散装袋 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 散装袋. 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.

Type A: FIBC bags are commonly used, among which u-bag and cubic bags, cone bags, and leakproof bags are the largest bags we produce.

Type B: antistatic bag, with an inner coating, with a breakdown voltage of no more than 4 kV on the bag body. This FIBC bag can be used in places with combustible dust, but not in dangerous areas.

Type C: Taihua Group factory produces its own conductive flat wire, weaves C-type conductive base cloth and produces C-type conductive bags and conductive inner bags. This kind of bag is suitable for filling and discharging in the environment of inflammable dust or explosive gas and has a correct grounding, so it is not dangerous.

Type D: this kind of bag is suitable for the packaging of various products that need to be packed with conductive bags. Its characteristic is that it does not need grounding. The static dissipative bag with anti-static coating and corona discharge effect is developed and produced by the factory.

यह bulk bag is a commonly used packaging woven bag, the use of a very wide range, can we know that after the use of bulk bag once, its strength will be reduced, there will be oxidation, why is this?

bulk bag in the natural environment that is in direct sunlight, in a week after the strength of the plastic bulk bag is reduced to 25%, after two weeks will be reduced by 40%, is basically unsafe. So the bulk bag storage problem is critical.

the bulk bag is made of polypropylene by drawing, weaving, sewing or paste, the loading weight is generally 200kg-3T.

the bulk bag should be placed in a cool and clean indoor storage, transportation should avoid the sun and rain, should not be close to the heat source, the storage period shall not exceed 18 months. In fact, 18 months of time plastic bulk bag may be aging, so you should shorten the duration of the bulk bag, should be within 12 months as well. the bulk bag should be stored away from direct sunlight.

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 散装袋? 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, 散装袋 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.
散装袋

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.
