Description
Technical field
The utility model relates to the fender guard field of goods transportation, refers in particular to a kind of aerated packaging film.
Background technology
Current Developing Logistics is rapid, the appearance of particularly ecommerce and fast development, day by day increases the buffering package protection demand of product in logistics progress.Traditional packaging packing adopts the materials such as fluting board, sponge or foamed plastic usually, by being filled between article and casing by packing, thus reaches shockproof protected effect.But the shockproof effect of above-mentioned packing is not very desirable.Market is in great demand to new amortizing packaging material.
At present, gas flushing pouch market occurred.Be not containing an air valve film, also need after inflation to seal, comprise limit inflation edge sealing.Another kind is the gas flushing pouch containing being spaced heat-resisting print structure air valve film, uses after inflating containing the gas column packaging bag being spaced heat-resisting printing air valve film without the need to sealing.All there is shortcoming in the product of above-mentioned two kinds of structures, the first in use must be supporting with inflation heat-seal equipment, and market use cost is high, complex operation; And gas flush packaging product can only use with filling bag and mat form, cannot form packaging bag pouch-type and use.The second is containing being spaced the gas flushing pouch of heat-resisting print structure air valve film when manufacturing, quite high requirement is had to packaging bag production facilities, namely require when producing that equipment has high-precision location and tension force controlling functions, simultaneously need accurate position point more in process of production, the inaccurate or tension force of position point is uneven excessive or too smallly namely cause the bad and loss of gas flush packaging product.Simultaneously because production operation is complicated, equipment operating workman needs long period professional training.Containing being spaced heat-resisting print structure air valve film, to the pitch requirements of heat-resisting printing, equidistantly also accuracy rate is high simultaneously, the base material of air valve film is PE plastic film stretch-proof poor performance, in production printing, dry answer, the process such as to cut in very easily to produce heat-resisting print gap bad and then produce and lose, thus this type of needs special production facilities and producer to provide containing being spaced heat-resisting printing air valve membrane material for specialities, make the manufacturing process of such gas flushing pouch loaded down with trivial details, productive costs is high, efficiency is low, is unfavorable for gas flush packaging industry development.Very easily defective products is produced containing the gas flushing pouch being spaced heat-resisting print structure air valve film owing to adopting, it is difficult that automation inflation realizes, therefore market still adopts manual inflation, causes at the bottom of work efficiency, client's user satisfaction is not high, increases gas flush packaging marketing difficulty.
Therefore, the present inventor makes further research this, and develop a kind of aerated packaging film, this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of aerated packaging film, and structure is simple, is easy to produce.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of aerated packaging film, comprise basement membrane, lower basement membrane, air valve film, described air valve film is double-decker, and air valve film wherein one deck scribbles heat-resisting printing, described heat-resisting printing is the list structure that free of discontinuities continues to connect, and air valve film shrinks formation free air diffuser gradually; Air valve film is arranged between basement membrane and lower basement membrane, and upper basement membrane and lower basement membrane are welded together to form filling channel by heat-sealing, and free air diffuser is communicated with filling channel, and filling channel is communicated with inflating cavity by free air diffuser.
Further, the structure of described inflating cavity is linear pattern or Pear-Shaped.
Further, described heat-resisting printing is no more than 1/5 of air valve film width.
Further, described upper basement membrane is connected by the short envelope of the heat of some dislocation with between air valve film.
Further, isolated between described inflating cavity by hot-sealing line, the lateral part of hot-sealing line is positioned in heat-resisting printing.
After adopting such scheme, the utility model compared with prior art, has the following advantages:
The gentle pressure be pressed in outside and inflation air cavity of the strip heat-resisting print structure air valve film that gas flush packaging of the present utility model utilizes free of discontinuities to continue to connect changes and material deformation interacts carries out air inlet and sealing, thus make the production structure of this gas flushing pouch simple, loss and cost reduce, easily manufactured, production efficiency is high; Meeting while manual inflation normally uses and realization can also used to complete gas flush packaging automation inflation in conjunction with another patent of contriver (patent No. ZL201420511661.6), be easier to meet the different demands that market uses gas flush packaging, improve market user's user satisfaction further.

Label declaration:
Upper basement membrane 1, lower basement membrane 2, air valve film 3, free air diffuser 4, filling channel 5, inflating cavity 6, heat-resisting printing 7, hot short envelope 8, hot-sealing line 9.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in the figure, the aerated packaging film of one that the utility model discloses, comprise basement membrane 1, lower basement membrane 2, air valve film 3, described air valve film 3 is double membrane structure, two-layer air valve film 3 shrinks formation free air diffuser 4 gradually, the intersection of free air diffuser 4 and filling channel 5, and be coated with the heat-resisting printing 7 of one deck in the aspect of upper basement membrane 1, described heat-resisting printing 7 continues the list structure of connection for free of discontinuities.Upper basement membrane 1 and lower basement membrane 2 are linked together by the short envelope 8 of hot melt heat be crisscross arranged with the hot-sealing line 9 forming independent inflatable cavity 6, form inflating cavity 6; this inflating cavity 6 is regular shape geometry container (see Fig. 3 or Fig. 4) structure; isolated by hot-sealing line 9 between adjacent inflating cavity 6; the lateral part of hot-sealing line 9 is positioned in heat-resisting printing 7; the top structure that adjacent two inflating cavities 6 are formed is conducive to bearing larger force value in inflating cavity 6, and then ensures gas flush packaging gas storage in use and quality supervision for arbitration.
One end of upper basement membrane 1 and lower basement membrane 2 is provided with a filling channel 5, and air, is filled with in inflating cavity 6 again through air valve film 3 by filling channel 5.
When inflating, being entered by filling channel 5 higher than atmospheric pressurized air, and entering in inflating cavity 6 through the free air diffuser 4 two-layer air valve film 3.After inflation, filling channel 5 is positioned at outside inflating cavity 6, air pressure in rear inflating cavity 6 is withdrawn higher than external pressure higher than atmospheric pressurized air, now, the air valve film 3 of double membrane structure is closed (Fig. 2) to side extruding by the air in inflating cavity 6, air between air valve film 3 is two-layer flattens closed naturally under being subject to the effect of material tension and squeese pressure, make inflatable chamber just can realize self-closing sealing and without the need to carrying out solder up, prevent gas from escaping.
Above are only specific embodiment of the utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
