Aforesaid bag is made up of forward and backward bag face, and anterior bag surface is made up of double-layer films at least, and film every locate to seal at periphery all round between two-layer be connected to form seal cavity; Described back pkt. face is made up of double-layer films at least, and film is every is connected to form seal cavity in periphery place sealing all round between two-layer;

The forward and backward bag face of bag is made up of three-layer thin-film as mentioned above;

Bag is made up of front, back, the left side, the right side as mentioned above, front, back, the left side, the right side are formed by the film of two separate at least, every layer film all is the tubular of bottom sealing, upper end open, and sealing was connected to form seal cavity at the upper end open place between film was whenever two-layer;

The front of bag, back, the left side, the right side are made up of three-layer thin-film as mentioned above;

The sack inboard is provided with raised line, groove as mentioned above.

The utility model compared with prior art has following advantage:

1, is convenient to detect, any one deck breakage can be with the naked eye or straightforward procedure judge whether bag leaks gas: manufacturer is as long as notices when vacuumizing whether the levels of bag is close together, if it is outer damaged, nexine can be close to clothing when vacuumizing, and can see having bubble or skin not to be close to nexine between skin and the nexine; Whether and it is damaged to detect nexine, can give the suitable inflation of vacuum bag, can see that at this moment skin heaves, and have bubble or skin not to be close to nexine between nexine and the skin; Concerning the customer, only need when buying, bag is open and flat, smeared with hand, just can above glass, paste glass paper, see between the about layer whether bubble is arranged, thereby can differentiate; Certainly the customer also can fold bag, if arbitrary layer of breakage arranged, air inlet between nexine and the skin, folding bag will be heaved, and it is equally smooth to be folded into the scraps of paper;

2, be convenient to producer and judge it is the gas leakage of bag film or closing device, the mouth of bleeding gas leakage, if the not gas leakage of bag film can detect and improve at closing device, the mouth of bleeding by emphasis;

3, reduced the leakage rate of product,, constituted multiple protective because bag has multilayer, one deck gas leakage has other layer to play guaranteeing role, even the customer has staved one deck because of carelessness in buying later use, can also continue to use the service life of having improved product; Have, the possibility that the hard thing in extraneous or interior boundary pierces through bag greatly reduces again, because after thing pierces through ground floor firmly, ground floor plays buffer action, impulsive force has reduced when stinging the second layer again, have second layer smooth surface to increase the difficulty that punctures the second layer greatly again, thereby bag is more durable;

4, saved productive costs: if detect the gas leakage of bag film, film can be reclaimed processing once again and use, so just save material processed; Detecting has not needed expensive equipment and complicated technology means, has reduced the cost of the equipment of acquiring; And method of inspection is simple, does not need for a long time;

5, simple in structure, make easily, help large-scale promotion production and use.
