Jumbo Bags often use the environment in the outdoors by the light, the amount of light in each region is not the same, will cause some foreign mistakenly believe that Jumbo Bags UV protection does not meet the requirements. It is recommended that Jumbo Bags manufacturers increase the amount of anti-Violet masterbatch appropriately according to the light difference of the region on the basis of the requirements of foreign businessmen, in order to improve product quality and prolong service life.

Jumbo Bags factory’s main processing raw materials are generally about three points：

1, the raw material: Hebei Wanfeng Jumbo Bags are using new material, some manufacturers will manufacture jumbo Bags special low price, then consider whether to use the return material, Jumbo Bags price labor costs under the condition of almost, We must see whether the material is a new pellet, whether to add an excess of back material, whether added modifier (calcium carbonate masterbatch),

2, masterbatch: masterbatch prices are also very different, some pigments can play on the anti-aging effect of Jumbo Bags, the impact on the life of Jumbo Bags is also very large, whether the use of Surface-Coated rutile titanium masterbatch, whether the yellow pigment with very good weather resistance, the blue pigment contains free copper, etc. will have a great impact on

3, anti-purple form and dosage can play a big role in the aging of Jumbo Bags, powdery UV due to the specific gravity and size and PP particles vary greatly, will produce precipitation, it is difficult to uniformly disperse the PP pellets, which will lead to pulling out the flat wire some very good, some very poor, thus affecting the anti-agingThe size and specific gravity and PP similar anti-purple masterbatch would not have such a problem.

Jumbo Bags according to the requirements to add anti-UV masterbatch, UV content can be selectively added according to different customer needs.

1, the UV content of masterbatch: each plant anti-purple masterbatch, the content may not be the same, the quality of the price is also very different, if foreign only provides the amount of anti-purple masterbatch, then the factory may use low UV content, low price of masterbatch, resulting in low UV content in Jumbo Bags. Jumbo Bags short turnaround period, UV content is generally low will not be a problem, but once a group of Jumbo Bags use a little longer, there will be damage to the accident, to the foreign impression is the factory used anti-purple masterbatch quality is not stable.

2, masterbatch formula to consider the cost, it is necessary to consider the cost of production should also consider the life of Jumbo Bags, masterbatch formulations in different factories will be different, whether to take into account the various factors affecting the life of jumbo Bags formula, jumbo Bags determines the stability of the application in a variety of climatic conditions.

3, masterbatch production: masterbatch production process parameters mature and stable, can guarantee the masterbatch in the process of UV loss is minimized.

4, masterbatch supplier brand awareness: general production has a long history of the enterprise Jumbo Bags are very mature, will not produce any quality problems, will choose a reliable long-term cooperation of masterbatch supply units, will from all aspects to enhance their product quality, service level, there is a standard system to protect the long-term stability of Enterprise Products, will not

Climatic factors, the quality of raw materials and the UV content of the anti-purple masterbatch are the three elements that influence the use effect of Jumbo Bags.

In everyday life how do we control the printing of space bags, also called Container bag, ton bag?
The colors of ton bags should match real, natural and colorful. The index should include two aspects; one is the field density tolerance of different sheets of the same product, Cyan (C) magenta (M) less than or equal to 0.15 black (BK) less than 0.20, yellow (Y) less than 0.10 ;
Appearance is the first thing, the layout must be clean, no obvious dirt; secondly, the color should be basically the same; that is the text, it should be complete, clear, accurate; and finally the size requirements. Fine product size tolerance is less than 0.5 mm, the general product size tolerance is less than 1.0 mm.
Of course, the printing quality of the Container bag depends on the following factors
First, personnel issues: personnel issues mainly reflect the sense of responsibility and technical proficiency of employees.
Second, the equipment process: the production of tons of container bags equipment aging, drying and send the bag technology will lead to a variety of problems such as adhesion container bag production process.
Third, the quality of raw materials: including ink quality, mixing uniformity, bag quality or offset printing problems and other raw material issues will lead to printing problems.

When we go to the market above to buy Anti-static container bag products is certainly wants to buy products, produce products that need to pick up look, can be seen through the appearance of Anti-static container bag quality is good or bad. Today we are going to introduce the anti-static container bag standard.

Standard of anti-static container bag

　　 Anti-static container bag inside the bag better transparency, surface free of impurities, black spots, heat sealing firm without leakage, damage, etc., the effective size of + 1CM to-2CM sewing size according to process single requirements±1CM, pin pitch 0.7-0.9 CM/needle. Anti-static container bag manufacturers starting and ending needle must coincide 5cm in the same suture line (the only needle pressed needle), strengthen the cloth from the needle in the upper left, suture, from the side of 1CM, sewing material bag is from the needle from the side of 1CM, needle down the needle. In accordance with the requirements of the use of sewing thread, sewing thread is not allowed to overlap, slatted, floating thread, leak buckle, under the Kang, etc., on the line tightness consistent. Sewing thread length retention is not more than 1.5 cm. Body and bottom seams, double Hemming than Qi, sewing three lines, the width of about 2CM, are not allowed to appear obvious wrinkles, lines and lines uniform, do not overlap, only the needle pressed against the needle. Sling sewing thread Margin 0.5 cm, suture from the Sling head 1CM, the body sling to be divided equally.

　　This is an Anti-static container bag. In the purchase of time can go to consider. Now the production of Anti-static container bag manufacturers very much, the enterprise competition is also very large. Enterprises want better development, in addition, to guarantee the quality, the price should be affordable, of course, innovation is an indispensable part.

Before we use the Container bag, we must ensure that it’s quality, performance meets the request, we look at its pressure and drop test methods.

When you stop the pressure test, the demand for the full load Container bag on the pressing machine to stop the pressure test, the pressure applied by the pressure Container bag full four times the weight, or the use of static load approach, namely four full load bag weight, pressing time is eight hours or more, if the contents do not overflow and

In the drop experiment, the full load Container bag, with lifting equipment to make it lifted, the bottom of the bag to separate the air 0.8 m above, and then to the hard flat air once vertical fall, if the contents of no overflow, Container bag no damage situation, it means that after this experiment.

When filling, the Container bag is aligned with the filling funnel mouth, Truss, in order to avoid dust or particles from leaking. Container bag is usually lifted up for filling, put the tray below in order to pull away after filling. er bag pressure and drop test

FIBC bags are different from ordinary woven bags because his bearing capacity than ordinary packaging is much larger, so his various parts of the suture are critical requirements, rather than ordinary plastic bags as simple heat on the line, is the need to go through multiple processes and other components are combined.
This goal is the FIBC bags the most important, the most important goal. The main factors affecting the strength of the suture are the variety and type of suture, stitch size, stitch, stitch, stitch or fold the suture to the edge of the bag scale, eager and cold cutting methods.
In general, FIBC bags production companies should develop internal control objectives for these influencing factors. About FIBC bags, national norms in the rules, the tensile strength of the main part of the convergence is necessary to reach more than 67% of the fundamental strength, the tensile strength of the bottom part of the convergence is necessary to reach more than 42% of the fundamental strength. On the cement bag on the sealing socket, advocate as the seam to the strength of the disposal, on the paper bag seam to the strength of the bottom, usually is not up to the goal, it is advocated to paste the bottom of the bag. About laminating cold cut bag, advocated the use of curling treatment, because of the cold cut marginal suture may tear out from the warp and weft. On the strength of the demand for non-woven bag catchy edge Week, Needle distance can be dense, the line can be fine.
More knowledge about FIBC bags can consult us, FIBC bags manufacturers welcome to order with FIBC bags, tons of bags demand.
