jumbo bags – Hebei Wanhefeng Package Co.,Ltd.

Jumbo bag manufacturers in the manufacturing process of jumbo bag, there are a lot of processes, during which a process is the drawing process, the width of the wire and the mild tension directly determines the quality of jumbo bag, tons of bag manufacturers to take you to understand the drawing process of jumbo bag.

When drawing, when extrusion of plastic film, the need to pay attention to such a few matters.After cooling the extruded melt film, according to the different types of flat wire to select the appropriate knife distance to cut.When cutting, should try to maintain the uniformity of the flat film cutting.Flat film after cutting to be obtained by thermal stretching treatment flat wire having a greater tension.However, in order to avoid flat wire greater shrinkage in the subsequent weaving process, but also should be heat-set treatment.After passing the cutting and drawing tests of such columns, we can characterize the quality of jumbo bag tons of bags.So, jumbo bag flat wire drawing process is still very difficult not to measure oh,and this is why many of us do not want to explore it.

About jumbo bag this high-quality and high frequency of use of packaging products,a little problem is inevitable,and these problems interrupt line is a very important issue in the meantime,and how to deal with it has become our top priority Oh.Disconnection is jumbo bag manufacturers sewing often encountered problems, suture quality is not required,the machine is not adjusted properly,over the line parts have a sharp mouth,the method of operation is problematic,the needle cooling is not sufficient, etc., will lead to disconnection. jumbo bag manufacturers are not allowed to appear short-term phenomenon.Ton bag manufacturers

When using the lock stitch jumbo bag sewing machine sewing uneven thickness of the product encountered disconnection fault, in addition to one by one to consider the analysis of the above reasons,should also pay attention to the two hook thread caused by disconnection.Sewing machine occupation is well known, because of the need to plan the distribution of action cycles,lock stitch jumbo bag sewing machine shaft and rotary shuttle transmission ratio of 1: 2.That is, the upper shaft rotation for a week,the Rotary shaft to turn for two weeks.

4 principles of jumbo bags design

Jumbo bags in the design according to the density of the goods(by the density of the goods can be calculated over the economic and reasonable size of jumbo bags)and state (powder need leak-proof,granular without leak-proof), containing the weight of the load, but also consider the distance of transport and how many times of handling,what kind of transport and transport methods?

1.Security

Mainly refers to the strength of jumbo bags.In the design according to the density of the goods (by the density of the goods can be calculated over the economic and reasonable size of jumbo bags)and the state(powdery need leak-proof, granular without leak-proof), containing the weight of the load, but also consider the distance of transport and how many times of handling, what means of transport and transport methods.

2.Sealing packaging materials are different, sealing requirements are different.Such as powder or toxic substances, afraid of contaminated items on the sealing performance requirements are very strict, prone to moisture or mildew of the material also has special requirements for air tightness.

3.Usage

In the design of jumbo bags, to fully consider the customer’s use of jumbo bags specific ways and methods, such as lifting, transportation, loading material performance.

4.Custody sex

Should be based on the user’s conditions of use, reasonable selection of materials, reasonable ratio. The anti-aging ability of plastic products in the sun exposure is currently more concerned about the problem, but also jumbo bags in the actual use of the process often encountered problems.

حقيبة جامبو It is made of polyethylene or polypropylene resin as the main raw material and a small amount of auxiliary materials. After blending, the plastic film is melted and extruded by the extruder, cut into wires, and then the drawing is stopped below the melting temperature of the resin. After molecular orientation and heat setting, the flat wire with high strength and low elongation is made. After warping, weaving and laminating, the plastic woven cloth is made as the base cloth, which is sewn with sling and shroud jumbo bag 。

The appearance requirements are as follows: the warp and weft lines of the base cloth are not allowed to present two broken holes at the same place, two less sparse files are not allowed to present within 100mm2, and obvious wrong weaving is not allowed. The base cloth coating shall not present the composite quality problems such as cracking, lack of film, delamination, bubble, hard block, etc. The sewing request shall be straight, without needle dropping, thread breaking, floating thread, no brooch, over needle, return needle at the place of needle dropping shall not be less than 3-needle sling request, with the limit deviation of 40mm. The printing pattern, text and mark shall be correct and clear, and the position shall be accurate.

Performance test method: jumbo bag used as the transport package of export commodities shall stop the top lifting test, dumping test, vertical impact drop test, positive position test, tear propagation test, etc. The handle type jumbo bag only stops vertical impact drop test, dumping test and base cloth test. For example, due to the export demand, in the process of ton bag consumption, anti UV ton bag has participated in the anti aging degree and anti UV ton bag in raw PP, and also improved the tensile strength of ton bag. At present, anti UV ton bag is widely used in product packaging of various industries.

Top lifting test: keep pressure at 6 times load for 5min. Vertical impact drop test: drop freely at 0.8m height. Dumping experiment: pull down the rack at a height of 0.8m, lift one end of the movable board, and drop the sample bag in the air. Positive position experiment: lift single or double straps (if there are four straps) close to the air to separate the bag from the air. The bag body and sling shall be free from damage and the contents shall be free from leakage.

استخدام jumbo bags will vary from season to season, so what are some of the details you should pay attention to when using the jumbo bag?

1. Make sure that the jumbo bag is folded up when not in use to reduce moisture and sun exposure, as the service life of the jumbo bag will be shortened due to the influence of the external environment. Also, pay attention to rain and snow, freezing temperature is low, cold weather will greatly reduce the use of products.

2. The secondary use of the problem, before the secondary use, the original loaded items should be emptied, avoid the loss of mixed items. There is also the problem of the environment in which it is used to reduce its impact on the jumbo bag.

3. Jumbo bag most plastics are resistant to acids, bases, and other chemicals. So in the use and storage requirements are not too high, but they also can bring great convenience. It is its excellent electrical insulation, it’s surface resistance, volume resistance are very large, large breakdown voltage, medium loss Angle tangent value is small.

Ton bags, also known as the jumbo bag, is a preferred method of carrying powder goods in long-distance transportation. Static electricity will occur in storage. How to prevent the harm caused by the static electricity?

In the process of storage, appropriate measures should be taken to make the static electricity disappear as soon as possible. We can set up a ground wire in the warehouse, and often spray water on the warehouse to keep a certain humidity or place a conductive floor under the FIBC bag goods.

Try to reduce the shaking in the ton bag, reduce the conflict, and change the handling method.

The price of container bags sometimes varies according to the price of materials.

For example, many enterprises use non-woven fabrics to sew container bags. What are the advantages of making أكياس ضخمة الحجم from non-woven fabrics? Non-woven fabric (polyester non-woven fabric, non-woven fabric) is also known as geotextile, which is a kind of permeable geosynthetic material and is formed by needling or weaving synthetic fibers. Burning wool non-woven fabric has excellent filtration, isolation, enhanced protection, high tensile strength, good permeability, high-temperature resistance, antifreeze, aging resistance, and corrosion resistance.

Pavement method of non-woven fabrics:

Cold rolling with manual service; Nylon cloth should be leveled and maintain a moderate deformation capacity.

The installation of polyester filament or polyester staple non-woven fabric is generally based on overlapping, sewing and electric welding of steel bars. The total width of sewing and electric welding is generally 0.1μm or more, and the total overlapping width is generally 0.2M or more. Non-woven fabrics that will be exposed for a long time shall be welded or sewn by electric welding.

2, non-woven fabric pavement processing technology:

Storage, transportation, and solution of non-woven fabrics

Burnt nonwoven rolls should be maintained from damage before installation. Non-woven fabric rolls should be piled up in areas without water. The height-to-width ratio of the stacks should not exceed four rolls, and the resolution of wire rope rolls can be seen. Non-woven fabric rolls must be covered with opaque raw materials to avoid UV embrittlement. In the storage process, the consistency of identification and data information should be maintained.

During the whole transportation process, the non-woven fabric roll must be protected from damage (including on-site transportation from raw materials storage to work).

Be sure to repair the non-woven fabric roll damaged by physics. Non-woven fabrics that are seriously damaged cannot be used. All non-woven fabrics that come into contact with leaked chemicals are not allowed to be used in this new project.

Non-woven fabric splicing

All splices must be carried out continuously (for example, point splicing is not allowed). Before overlapping, spunlaced nonwoven must overlap less than 150 mm. Smaller needle gauge selvages (exposed edges of raw materials) shall be at least 25 mm.

The self-hand woven non-woven fabric connector comprises a 1-thread and a thread chain sewing mode. The thread used for sewing should have a strength of over 60N and be equivalent

Composite resin with acid resistance and ultraviolet resistance on or above nonwoven fabric.

People who have used أكياس ضخمة الحجم must know that there is a strap on the jumbo bag for easy lifting. Sling plays a vital role in the lifting process, so jumbo bag manufacturers in the design of the strap should be enough attention. So how to design a sling is enough science?

jumbo bag in the design to consider the volume of tons of bags, containing the weight of the load and the number of packaging units, but also consider the distance and the number of transport distances and handling times, the use of which means of transport and transport methods. For the above factors, the load-bearing capacity of the Sling should be very good, the general jumbo bag bearing is basically more than one ton, so before the use of the batch to do the testing of tensile force.

When the Sling is connected with the bag body, there are various forms of ceiling hanging, bottom hanging, side hanging, etc., and through the suture connection, so the future is also very important, only with high strength, fabric and suture can not reach a certain strength, can not ensure the overall performance of the حقيبة جامبو.

jumbo bag wants to achieve higher performance, not only need to consider the design of the Sling but also need to improve the overall.
