Description

Pliable and tough tillot bag

The utility model is addressed the textile bags of being made by pliable and tough internal layer, is used for preserving and transporting goods, for example fertilizer, flour, sugar, chemical substance etc.

Usually lot cargo is placed in the textile bags, is in order to preserve easily and to transport goods.But if place certain goods, textile bags just must have an inside liner so, to keep goods cleaning and excellent.

Textile bags road with inside liner often is to be made by textile material, and this textile material makes this bag that a large amount of pores be arranged, and inside liner is to be made by plastic sheeting.When lot cargo is loaded in the bag, in the local time that we trying to move to another, inside liner (being made of plastics) is torn sometimes, and this can cause steam to enter in the bag, goods is made moist and damages.

In addition, the pore of plastic sheeting is too little, so air can not pass.If textile bags is placed in the room of a heat, because of in owing to be heated, the water evaporates that contains in the goods and make interior the air change of bag damp, this can cause goods to make moist and damage.

The utility model will address the above problem, because inside liner is to be made by firm nonwoven fabrics, and have very high elasticity and can tearing hardly.

The purpose of this utility model provides has high-flexibility and firm inside liner textile bags.Another purpose provides a kind of inside liner, and it is harmless that this inside liner can make the goods that is housed in the bag remain intact.

For these purposes, the utility model uses a kind of nonwoven fabrics inside liner of being made by polypropylene, polyethylene, and its pore allows air to pass, but stops steam to enter in the bag, and goods remains intact harmless in the feasible bag.

Textile bags includes two linings, promptly outer lining and inside liner.Be to make in outer the benefit by 97% polypropylene and 3% calcium carbonate fabric or polypropylene, polyethylene plastic fabric.Inside liner is the nonwoven fabrics of 10 micron thickness, is made by polypropylene, polyethylene.Inside liner can be with two kinds of method settings: 1. the nonwoven fabrics inside liner is placed on the inboard of textile bags.This bag is used for preserving chemical substance, so that we can guarantee that this textile bags of wrapping inside liner can not tear.2. form in the interior benefit, be by folding and make nonwoven fabrics until looking like a big pocket, closed end that then will this big pocket is placed on the bottom and the medial surface of textile bags, or stitched together with the edge of textile bags bottom, but the open end of big pocket is placed on the inside portion, top of textile bags.The open end of big pocket is higher 10 centimeters than the top of textile bags, after perhaps the top of big pocket openings partial sum textile bags being kept flat, again with them together towards the inside portion folding and sew it up, so that the open end of big pocket and the top of textile bags are pasted together.The top of the textile bags of sewing it up is then done in this folding action after textile bags is filled.This folding partly is to be used for preventing that goods from pouring out from textile bags.The width of inside liner is wideer 2 centimeters than textile bags, and therefore when filling goods, the surface energy of textile bags medial surface is pasted together with inside liner securely.

This textile bags (having inside liner) is by filling any lot cargo, for example flour, sugar, fertilizer, chemical substance etc., and have the same place of different humidity and temperature to place some times at some to do overtesting, test finds that goods remains intact harmless.

Fig. 1 is the schematic perspective view of the utility model tillot bag.

Symbol among the figure: 1-polypropylene, polyethylene nonwoven fabrics is as a nonwoven fabrics internal layer

2-polypropylene, polyethylene plastic fabric bag is as the outer bag/layer of fabric

The pliable and tough tillot bag of the utility model comprises the outer lining be made up of fabric and the inside liner of nonwoven fabrics.Inside liner is placed on the medial surface of the outer lining that is pasted together with the textile bags inside part, the perhaps formation of inside liner, be that nonwoven fabrics is looked like a big pocket through folding with being sewn into, closed end that then will this big pocket is placed on the bottom and the inboard of textile bags, or it is stitched together with the edge of textile bags bottom, but the open end of big pocket is placed on the inside portion, top of textile bags, after perhaps the top of the opening portion of big pocket and textile bags being kept flat, again with them together towards the inside portion folding and sew it up, so that the open end of big pocket and the top of textile bags are pasted together.Inside liner is made by the nonwoven fabrics of polypropylene, polyethylene, and the 10-100 micron thickness is arranged, and the width of inside liner is wideer 2 centimeters than the width of textile bags.The packaging bag project organization has two layers of combination layer, and polypropylene, polyethylene/plastic fabric (barrel-type bag/fabric cloth/shell bag) is as fabric outer 2, with polypropylene, polyethylene nonwoven fabrics internal layer 1 (barrel-type bag/nonwoven fabrics/bags) combination as inside liner.These two layers of combination layer structures with PP/PE fabric and nonwoven fabrics are particular design, and it has three functions, for example:

1. a good airiness circulation can be arranged in the package/bag the inside.

2. can absorb watermark and moisture, keep in the bag xeothermic state being arranged.

3. it must be firm, because packaging bag is to be used as the instrument that distribution is sold.Its requirement can be caught, and the weight of the minimum 20-2500 kilogram of packing in a bag/container/cloth, must be in transit firm.It must be to have good tensile strength and stretch ratio, cleans and is food stage.

Pliable and tough textile bags is used in particular for replacing gunnysack and cotton bag.Though they are to have used different raw materials, they have similar function.With compare with cotton bag as the gunnysack of their raw materials with cotton with the jute fiber, the design of our new packing bag is as raw material with polypropylene, polyethylene.Having this packaging bag design-calculated purpose is:

1. there be not other bag can replace gunnysack and cotton bag and their function at present.

2. limited their former section a period because have: jute and cotton, this is to just finding these bags

Be restricted.

It price every year all increasing.

We know that flour preferably packs with cotton bag.Reason is that cotton bag can keep the hot state of the inside universe, because they have a good airiness.Second reason is that they also can absorb watermark, because flour is heat/temperature before in the bag of packing into.Flour is identified and is confirmed by watermark.

They require have a kind of like this packaging bag to be used for packing into can absorb the goods of watermark, if there is not this bag, be insect, tick, bedbug just also then, the undesired plant larva, fungi and growing of other bacterium provide the place, this will directly influence by the life-span of consumption goods, the color of goods and the original also slight change of comparing sometimes.

The 3rd reason requires to have these special bags to be used for loading when distribution is sold.This bag of picture gunnysack and cotton bag is most popular to the flour producer, and regrettably these two kinds of bags are difficult to find.And price also goes up during this period.Yet they still use this two kinds of bags, Gu for there not being other bag, even this still is a bigger problem to them some day sooner or later.

This product is the replacement of identity function, and its project organization is compared with being substituted thing, also has additional advantage:

A. pliable and tough tillot bag is compared with gunnysack does not have fiber;

B. be food stage;

C. firmly, cleaning, obtain easily, and produce easily anywhere;

D. make raw material with polypropylene, polyethylene;

E. the quality that when transportation, keeps goods in the bag;

F. seeming has reasonable performance, exquisite appearance and useful protection;

G. price is a considerably cheaper.
