Abstract

The utility model relates to an exhaust-type gasbag packaging bag; a bag body thereof is formed by plastic layers and provided with an inner bag and an outer bag; the inner bag is arranged in the middle of the outer bag; the two plastic layers of the inner bag are in belt-shaped combination with the two plastic layers of the outer bags; the four plastic layers are provided with inlet ends; an inflation tube is arranged between the inner bag and the outer bag; a one-way valve plate is mounted at the opening of the inflation tube; exhaust holes are formed on the plastic layers of the outer bag; and adverse pressure valve plates are mounted on the exhaust holes. The exhaust-type gasbag packaging bag is an energy-saving and environment-friendly plastic gasbag packaging product which integrates the functions of vacuumizing, inflating and exhausting, and is made of the double-layer material and structure, thereby forming the inner/outer double-layer bag; when the article to be packaged is placed in the bag for inflating, the packaged article can be packaged by the inner bag in a manner that the inner bag is fully attached to the packaged article by the shape thereof, so that the article is fixed at the center of the bag body; and the gasbag is formed between the inner bag and the outer bag, thereby providing secure protection for the article fixed by the inner bag. The gasbag packaging bag has the advantages of easy manufacture, low cost and recycling use for a plurality of times.

Description

The packaging bag of exhausting air bag

Technical field

The utility model relates to gas packing bag, but particularly a kind of air sac packaging bag of Puffer-type exhaust.

Background technology

Existing gas packing bag is a Puffer-type, be with inner bag vacuumize, outer bag inflation, utilize outer bag inflation and produce air pressure, make inner bag vacuumize naturally, the article that firm thus inner bag is loaded make it be difficult for moving, and can prevent that external force is to the wherein extruding of connection with wrapping of piece.But the Bag structure of existing gas packing bag is comparatively complicated, makes comparatively trouble, and can not recycle, and does not meet environmental protection.

The utility model content

Task of the present utility model provides the packaging bag of a kind of improved exhausting air bag, and it has solved the problem that the Bag structure of existing gas packing bag is comparatively complicated, make trouble, can not recycle.

Technical solution of the present utility model is as follows:

The packaging bag of a kind of exhausting air bag, it constitutes bag by plastic layer, be provided with inner bag and outer bag, inner bag is arranged on the centre of outer bag, two layers of plastic layer of described inner bag are banded with two layers of plastic layer of outer bag respectively and combine, one end of these four layers of plastic layers is an entrance point, inner bag and outside the bag between be provided with appendix, at aerating pipe port check valve sheet is housed; The plastic layer of described outer bag is provided with deflation hole, and the contrary valve block of pressing is housed on deflation hole.

Exhausting air bag of the present utility model packaging bag is that vacuum, inflation and degassing function are combined; adopt double layer material and structure fabrication to form; thereby formed inside and outside double-ply bag; after products to be packaged are placed in the bag inflation; inner bag fully by the shape of products to be packaged with its fit wrapping; article promptly are fixed on bag central authorities, produce air bag between the inside and outside bag, and the article that utilize the air bag cushioning principle that inner bag is fixed obtain safety guard-safeguard.When packaging bag was clashed into or shake, article can not be affected in bag, thereby had prevented the article damage.Because the utility model has adopted the professional contrary valve of pressing, therefore gas can not leak out in the bag.

The utility model is a kind of energy-saving and environmental protection plastic air bag packaging product, meets environmental protection.The utility model can be according to the corresponding shape of the shaped design of packaging article, thereby makes article packing reach minimum volume.The volume of the volume ratio expanded material packing behind the article packing is little, has dwindled storage, transportation space thus, has alleviated the overall weight of products to be packaged, has reduced storage, cost of transportation.This product is owing to be transparent wrapper, so the article of packaging can show its authenticity, is convenient to again confirm article in the bag, played anti-fake effect.

This product adopts gas flush packaging, and is much simpler than traditional manner of packing, and shortened the operating time, can save the time about 50%.This product is pressed in the valve as long as insert the contrary of deflation hole with common suction pipe after each the use, the gas in the air bag emitted, and the taking-up article, packaging bag just can repeated usage, has saved packing cost thus.This packaging bag can fill matched with it gas at different connection with wrapping of piece, carries out best protection with the article to packaging.When packaged food, fruit, can charge into corresponding gas at different commodity, make food, fruit reach best fresh-keeping effect, and can take freezing, insulation measure in good time.

Exhausting air bag packaging bag manufacturing of the present utility model is simple, with low cost, and the intensity height is not fragile, safe and reliable, easy to use, can repeatedly recycle, and is environment friendly and pollution-free, saved the energy.But this packaging bag widespread use is used for the packing of high-accuracy and frangible explosives such as medical machinery, precision instrument, electronics package, stream juice body, drinks, workmanship, pottery art, glass ware, fruit, vegetables, food, electronics electronic toy, Liquid Crystal Display (LCD), ice bag, air conditioner, laundry machine, digital product, is applicable to fields such as national defence, science and technology, family life, supermarket, market, industrial enterprise, postal consignment, express delivery logistics.

Description of drawings

Accompanying drawing is the structural representation of a kind of exhausting air bag of the present utility model packaging bag.

The specific embodiment

Referring to accompanying drawing, the utility model is the packaging bag of a kind of exhausting air bag, and it constitutes bag by plastic layer, and whole bag is provided with inner bag and outer bag, and inner bag is arranged on the centre of outer bag.

Two layers of plastic layer of inner bag are banded with two layers of plastic layer of outer bag respectively and combine, and it is bonding that this band shape is combined into 1 compacting of hot pressing band.This hot pressing band 1 can be provided with some, just forms air bag between the inner bag between the adjacent hot pressing band and the outer fluid-pressure moulding bed of material.

One end of four layers of plastic layer of inner bag and outer bag is an entrance point, various article can be put into inner bag from entrance point.

Inner bag and outside be provided with appendix 2 between the bag, appendix 2 leads to bag outside.2 mouthfuls check valve sheet is housed at appendix, to charge into gas to internal bag and between the plastic layer between the outer bag.The air pressure that charges into gas by check valve sheet is directly oppressed inner bag, thereby makes the inner bag chamber of depositing article form vacuum.

For making the air bag packaging bag adapt to the environmental protection needs, be convenient to repeated usage, be provided with deflation hole 3 on the plastic layer of special bag outside, the contrary valve block of pressing is housed on deflation hole 3.After using up the air bag packaging bag, insert the contrary of deflation hole with common suction pipe and press in the valve block, the gas in the air bag is emitted, just can the repeated usage packaging bag.

When air bag packaging bag of the present utility model was inflated, factory operation can adopt the constant pressure type air pump, carried out the balance inflation; The then available common air pump of small-scale packing material, inflator are put on the air.

Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim variation, the modification of the foregoing description.
