We do not have many contacts in the container of ton bags in our lives, but their application in factories and enterprises is indispensable. Tons of bags-literally the explanation is that it can hold more than one ton of bags. Ton bags, like ton bags, space bags, and space bags, are a common name for container bags. Because ton bags are usually contained in 1 ton of goods, they are commonly called ton bags. The cargo has various specifications of 0.5-3 tons. FIBC is a flexible transport packaging container, which is widely used in the transportation and packaging of powder, granules, and bulk goods such as food, grain, medicine, chemical industry, mineral products, etc. Warehousing packaging products.
The ton bag FIBC is mainly made of polyethylene or polypropylene resin, and a small amount of auxiliary materials is added. After mixing, the plastic film is melted and extruded by an extruder, cut into silk, and stretched below the melting temperature of the resin. Molecular orientation and heat setting make high-strength, low-elongation flat yarn, and then warp, weave, and laminate to make plastic woven cloth as the base cloth, and sew with the sling and surrounding belt to make a flexible container bag. Among them, the sling is also made by mixing, drawing, weaving and other processes. At present, a sling caused by cracked silk weaving is getting more and more widely used. It has the characteristics of low weight, high tensile strength and beautiful appearance.
For flexible container bags used as transport packaging for export commodities, according to SN/T0264-93 "Inspection Procedures for Flexible Container Bags for Export Commodity Transport Packaging", handle type flexible container bags according to SN/T0183-93 "Export Commodity Transport Packaging The inspection regulations for carry-on FIBCs stipulate the inspection and refer to GB10454-89 "Flexible FIBCs".
①The warp and weft of the base fabric is not allowed to appear in the same place with 2 broken holes, within 100mm2, there is no sparse 2 less, and no obvious misweave is allowed.
②The compound quality problems such as cracking, lack of film, delamination, air bubbles and hard blocks are not allowed for the base fabric coating.
③Sewing needs to be straight, without needle removal, thread breakage, floating thread, no hanging needle, over-needle, and no more than 3 stitches at the needle drop position.
④ Slings are required to be of equal length, with a limit deviation of 40mm.
⑤The printed patterns, characters and marks are correct and clear, and the position is accurate.
(2) Performance inspection: Flexible container bags used as export packaging for export commodities shall be subjected to top lifting test, dumping test, vertical impact drop test, position test, tear propagation test, etc. Handle-type flexible container bags are only subjected to vertical impact drop test, dump test and base cloth test.
① Lifting test at the top: hold the pressure for 5 minutes with 6 times load.
②Vertical impact drop test: free fall at a height of 0.8m.
③Dumping test: drag the drop frame at a height of 0.8m, suspend one end of the movable plate, and make the sample bag fall on the ground.
④Position test: Lift the single belt or double belt close to the ground (if there are four slings) to make the bag body leave the ground.
In the above tests, the bag body and the sling must not be damaged, and the contents should not be leaked.
⑤Tear propagation test: draw a cut with a length of 100 mm and a vertical line of 45° on the bag body, hang it from the ground, apply 2 times the load, and keep it for 5 minutes.
