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.
In our daily life, حقيبة جامبو has become the main production material of our packaging, jumbo bag load-bearing and tension is essential,why the same kind of bag different customers install the same product load-bearing is not the same, let us understand the jumbo bag packaging skills, and how to prevent jumbo bag after loading does not fry the bag.
First, the jumbo bag is made of warp and weft yarns, and the bottom of an ordinary jumbo bag is narrower than its height, for example 50 *by 80, 50 cm wide and 80 cm high.Small and large side in this case, if the bottom of the unloading area lands first, and the weight of the product is small, the pressure increases and the bag is easily torn.If the side is on the ground and the landing area is large, an explosion usually does not occur in this case.Secondly, when loading powdered or granular products, the loading amount is too full, or the loading amount is too full, when the dumping is stopped, the force acts directly on the jumbo bag, so that the bag’s silk is easy to break.Typically, the load is usually half or two-thirds or more, leaving the neutral.When unloading, the force inside the product is gradually reduced, the force acting on the jumbo bag is very small.This prevents the rupture of the jumbo bag.This is also the technology of loading jumbo bag manufacturers.
jumbo bag are warp and weft intertwined, the general jumbo bag bottom is narrower than the height, for example, 50*80, width is 50cm, height is 80cm, that is to say after loading the goods bottom area to be small, side area to be large.In this case, if the bottom area of the unloader to the ground, the weight of the goods on all the smaller bottom area, the pressure is large, the bag is easy to be torn.If the side area of the ground,the ground area is large, in this case generally does not appear bag fried bag phenomenon.This is a little trick to unload the goods to avoid fried bags.
If you install powdered products or granular products, when loading do not be too full, too full, unloading truck thrown down, the power acts directly on the jumbo bag, it is easy to cause the bag wire fracture.Normal loading is generally loaded more than half, or two-thirds, set aside neutral, when unloading, the power will slowly become smaller in the interaction of the product inside,acting on the power of jumbo bag is very small, so as to avoid the rupture of jumbo bag phenomenon.This is also the skill of jumbo bag loading.
UV-resistant Jumbo Bags ,that is, UV-resistant container bags,used for chemical product storage and transportation packaging, container bags are one of the uses of chemical container bags. Is designed by the characteristics of chemical raw materials themselves packaging materials, in addition to carrying and other requirements, generally also to ensure the integrity of its packaging items, safety, as well as in line with the provisions of the corresponding national packaging materials.Tons of bags, also known as flexible container bags,tons of bags, space bags, etc., custom tons of bags tons of bags container bags, English translation of a variety, FIBC, is a kind of container unit appliances.
Tons of bag manufacturers in the production of the need to pay attention to a lot of matters, first of all to stand in the consumer’s point of view to consider, below we will introduce in detail.
The safety of tons of bags is the first thing to consider.In the design to consider the packaging volume,the weight of the load and the number of packaging units, but also consider the distance of transport and how many times of handling, what means of transport and transport methods.The practicality of tons of bags, to fully consider the specific ways and methods of customers to use tons of bags, Shandong tons of bags, such as lifting, transportation, loading material performance.Tons of bags of sealing, consumers for tons of bags of sealing performance requirements are different, so we should fully take into account.Such as powder or toxic substances, afraid of contaminated items on the sealing performance requirements are very strict, prone to moisture or mildew materials on air tightness also have special requirements.
Ton bags are mainly used in bulk,granular or powdery items, the physical density and degree of loosening of the contents of the use of different effects.
The performance of the ton bag should be as close as possible to the customer to load the product to do the test, which is the standard written in the“Test special standard filler”, as far as possible to make the technical standards to meet the challenges of the market economy.
What role can UV-resistant Jumbo Bags play?
1, container bag manufacturers packaging restrictions are very large.Powder and granular products can be packaged in container bags.
2, improve the loading and unloading power.It has a large capacity, loading and unloading is very fast, more than ten times more efficient than conventional paper bag packaging line.
3, can effectively maintain the product.Container bag data is rain-proof, impermeable function, after filling in the Outdoor can also be moisture-proof.
4, take up less space.Empty bags can be folded,small size, round tons of bags tons of bags, full bag capacity.
5, long life, UV-resistant Jumbo Bags tons of bags,can be used repeatedly.Ton bags are made from high-strength data, durable, and can be accepted and reused.
Cement is the main material to build a house, often see the cement packaging is in the form of woven bags plus lining, usually a bag of cement in about 100 pounds. We know that the use of cement as an important building materials, the amount is very large, small bags of cement, although very convenient to use, but in the transport process, encountered the car is broken,the need for transport will be very troublesome.Affected by the current logistics, with jumbo bag cement, can be easily used, but also fast transport, very convenient, low cost.
Cement because of its easy to fly afraid of moisture characteristics, transportation must be used when the package.The bagged cement is easy to handle, metering, storage, and the same situation is higher than the price of bulk cement, so despite the current China’s cement industry in vigorously promote bulk cement, but enterprises are still widely used bagged method.
In 1,000 tons of cement shipping, for example, the traditional manual handling unloading from the ship to the shore takes at least 2-3 days, labor costs per ton of cement about 20 to 30 yuan, in addition to the addition of ship parking fees, bagged cement damage caused by the loss.The jumbo bag costs only 2 dollars per ton, high efficiency, no damage.In comparison, the advantages of loading cement with jumbo bag are obvious.
Easy loading and unloading, for the cement industry to reduce labor costs is the embodiment of the vitality of our products.And the breakage rate is 0, reducing the pollution caused by cement dust, in line with environmental requirements.
Jumbo bag bearing large cargo and large tonnage of goods special plastic bags,and woven bags is different, jumbo bag is oriented to large tonnage of goods, requiring bearing capacity and compression performance is relatively strong, this is what we have seen and a consensus. So, for jumbo bag compression performance test is very important,what are these aspects?
Overall, jumbo bag is light in weight.Low cost, reusable; high tensile strength and impact resistance, and elongation is small; wear resistance, acid and alkali resistance, corrosion resistance, durable, can be used in harsh conditions of the environment; good permeability, easy to clean; in jumbo bag lined with a film or coated with a layer of plastic, it has excellent waterproof, moisture resistance, but also improve the plastic woven bag jumbo bag
Plastic woven bag limited heat resistance, resistance to purple jumbo bag poor, easy to reduce the strength of outdoor use.Has excellent cushioning shock resistance,excellent sound insulation, heat insulation, good heat sealing, but also has a non-toxic, tasteless, impact resistance, moisture, corrosion resistance, good transparency and so on.
Home in the purchase of goods will have a special shopping bag,and the goods will be packaged with a special bag, then the bulk powder granular material needs to use what kind of bag to package it? This time we have to mention jumbo bag. jumbo bag belongs to a flexible transport packaging container,use it as a powder, bulk and granular materials packaging is perfect!Using jumbo bag to package these materials can effectively improve the efficiency of loading and unloading, but also can reduce the cost of Transportation, which is the main reason many enterprises choose jumbo bag!So what aspects do jumbo bag need to consider when designing?Here by jumbo bag factory to tell everyone!
Elements to consider when designing jumbo bag：
1.Strength: factors to be considered in the design, the volume of the package,the weight of the contents and the unit of the package(the number of packages)also need to consider the transport distance and the number of transport, as well as the mode of transport and mode of transport.Material: reasonable selection of materials should be based on user conditions and reasonable processing ratio. For example, the ability of plastic materials to prevent aging in the sun is the main indicator of the quality of the container. In the production process, attention should be paid to the use of anti-UV agents and the choice of anti-UV materials.
2.Sealing: different packaging materials, different sealing requirements,such as powder or toxic materials, afraid of contaminated items, the sealing performance requirements are very strict. When designing container bags, pay attention to the impact of the base film coating process and sewing process on sealing performance.
3.Availability: in the design of the container bag, it is necessary to fully consider the lifting and transportation of the container bag and the performance of the loaded material.
4.Usability:consideration should also be given to whether packaged food is food and to ensure that there is no adverse effect on packaged food.
These are the four elements that need to be considered when designing jumbo bag.For a jumbo bag, only grasp the four elements to design it in order to ensure its quality and performance,so as to make the design of jumbo bag better applied to the enterprise, but also to protect the effect of jumbo bag loaded materials!
حول jumbo bag this high quality and high frequency of use of packaging products,there is a problem is inevitable, and these problems infix line is one of the very important issues, and how to deal with it has become our urgent need Oh. Disconnection is jumbo bag sewing often encountered problems, suture quality does not meet the request, improper adjustment of the machine, over the line parts have sharp mouth, operating methods have problems, needle cooling is not abundant, etc., will lead to disconnection. jumbo bag factory direct jumbo bag is not allowed to present short-term phenomenon.
When using the lock stitch jumbo bag sewing machine sewing uneven thickness of the product encountered disconnection fault, in addition to thinking one by one to analyze the above reasons,but also should pay attention to the two hook line caused disconnection.Sewing machine industry is well known, due to the needs of the distribution operation cycle design, lock stitch jumbo bag sewing machine shaft and hook transmission ratio of 1: 2.That is, the upper shaft to turn a week, the Rotary hook shaft to turn two weeks.
jumbo bag bearing large cargo and large tonnage of goods special plastic bags,and woven bags is different, jumbo bag is oriented to large tonnage of goods, request bearing capacity and compressive performance comparison is strong, this is our full view and a consensus.So, about jumbo bag compression performance test is very important,what are these aspects?
Overall, the jumbo bag is lightweight.Can be used for harsh conditions of the environment;good permeability, easy to clean;in jumbo bag lined with a film or coated with a layer of plastic, it has a waterproof, moisture-proof performance, but also progress of the plastic woven bag jumbo bag lubricity, is not conducive to jumbo bag stacking.
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.
Of course, the printing quality of the container tons of bags depends on the following elements, personnel issues: personnel issues mainly reflect the employee’s sense of obligation and technical proficiency level. Equipment technology: container tons of bag equipment consumption aging, drying, and bag feeding technology will lead to the container bag consumption process presents a variety of adhesions and other issues. The raw material is good or bad: including ink quality, mixing average, bag quality, or offset printing problems, and other raw material problems will lead to printing problems.
Jumbo bag manufacturers in the consumption of jumbo bag are very careful, they will use the data processing, which will use the spinning process consumption FIBC, but spinning process compared to the trouble, always present in the consumption or more or fewer problems, but the phenomenon of bamboo during surgery, what is the reason? The cooling water temperature is high. The crystallinity of the polypropylene film is too large.
Stretching temperature is low. Oven temperature is low, or uneven temperature spread, which leads to spinning is stretched at inappropriate temperatures. The extrusion temperature is low. The extrusion temperature is low, the film is not plasticized. The stretch ratio is low. The stretch ratio is low, the blank is not stretched enough. Bag manufacturers in the packaging process of consumption in the process of consumption of bamboo yarn have a great impact on the quality of the bag, so the net bag manufacturers will spend a lot of human and material resources. About this.
jumbo bag is a new type of packaging container. Admittedly not presented for a long time, but it carried out quickly. The use of container bags can speed up loading and unloading efficiency. Its large capacity, loading, and unloading speed. Paper bag packaging a lot; transport is also very bento, the jumbo bag has a special ring, bento lifting equipment used. the jumbo bag takes up very good space. After folding can store empty bags, but after the expansion of the empty bag capacity; container bags use long life, can be used repeatedly.
