'Branches' become a key component in the composite vacuum packing bag manufacturer

composite bags silk yield process consists of raw materials and auxiliary materials mixed after by extruder melt extrusion into a film, it membrane through cooling, cutting into the silk ( Grey silk) , then through stretch orientation flat wire, finally put the flat wire winding on the bobbin, made some send the process engineering produce woven fabric weaving process.

produced by flat silk weaving cloth woven fabric weaving process is the flat silk cloth. About cylinder cloth, with circular loom weaving, circular loom warp the rack there are a lot of spindles, according to the weaving BuFu width, and flat wire width, using rules limit the number of warp. Warp before entering the circular loom, a brown box of warp warp in weaving, weft shuttle through the warp in weaving make make circular activity, woven cloth.

its production process is: all woven cloth printing, cutting, sewing, and pure aluminium bag. Is different depending on the equipment, can be cut before printing, also can be printed after the first cut. Active cutting sewing can continue to complete printing, cutting, sewing and other process, also can be made into valve pocket, bag, etc. , that put an end on flat bag after weaving raphe adhesive can be performed. Popular bag bag making process goal first is public servants size, the bottom of the seam and the seam edge to the tensile force, clarity of printing ink and other parts of the cleanliness after printing, the layout position accuracy, sutures, stitch, and suture needle, break the defect such as the

composite plastic woven bag:

two -, three functions such as composite plastic woven bag production process is to weave cloth, Shanghai juji material and paper or film, composite or Shanghai juji. Cylinder cloth or piece of cloth, barrel can be cutting, printing, sewing, made popular seam bottom bag, also can punch, folding, cutting, printing, sewing, make cement bag, piece of cloth, can raphe adhesive, printing, cutting, paste, paste at the bottom of bag. Also can welding, coiling, made, tarpaulins, geotextile. Composite bag making process the key is.

Shanghai juji reason is the resin in molten form coating on substrate woven cloth. Only the molten resin coated to woven cloth and cooling, immediately get two-for-one woven cloth. If the answer of the season, the molten resin film clip at fabric and paper or plastic film center, and then cooling for Shanghai juji triad woven cloth can be plain fabric single Shanghai juji get the piece of cloth, can also be for cylinder cloth double-sided Shanghai juji, Shanghai juji cylinder cloth. Shanghai juji after woven fabric can be printed, cut, suture made into all kinds of bag type, wide Shanghai juji cloth can be winding as a tent factory.

zhisu composite bag through the production of renewable raw materials, can be after dry mixing raw materials, into the wire drawing machine cylinder, for heating the molten plastic. Heating temperature subsection control of wire drawing machine, cylinder temperature is presented. the rise, to the die head to keep constant. Produced zhisu composite bag bag of silk. According to the pure aluminum bag material performance and the type of flat wire, wire and reworked material mixed proportion of different density, wire drawing machine heating temperature control are also different. Usually can be combined with the model of raw material, equipment performance and to determine the actual experience. Polypropylene new material molding temperature control at 160 ~ 250 ℃, the reworked material forming temperature according to the size of the mix proportioning can be appropriately reduced to 150 ~ 200 ℃.

plastic melt before the membrane filtration of paper-plastic composite bags, its purpose: one is the filter material of impurities, the second is stable pure aluminium bag of material flow, three is to make products more compact. Reworked material to the processing of wire drawing machine, in larger networks usually do, and using artificial network, its purpose is: to reduce artificial in network times, reduce the cost to replace the network. Filter layer, in general, should be based on the clean degree of the reworked material and experience. Guangzhou woven bag factory reworked material mixed with large quantity and a lot of impurities, the filter should be loose some; Reworked material mix proportioning of the small and clean, the filter can be close. The filtered molten material through the die out after the film, would immediately for cooling. Flat membrane water, commonly used wire drawing machine. Zhisu composite bag reworked material of cooling temperature can be controlled between 35 and 45 ℃. Cooling has three purposes: one is helping to shape the melt; The second is to avoid material of high temperature oxidation; 3 it is to prevent crystallization of materials, easier to hot stretching.

zhisu composite bag of reworked material hot stretching and finalize the design temperature control at 90 ℃ and 100 ℃ or so, according to the type of flat wire, linear density, size, and then how much can be appropriately adjust the raw mix proportioning. Draw ratio according to how much control to raw mix proportioning in 4 ~ 6 times. Reworked material, draw ratio can be smaller; Reworked material, draw ratio can be larger
