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 jumbo bags 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.

  1. 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.

  1. 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.

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.
