Description

It is provided with the packaging bag for refrigerating of handle

Technical field

The present invention is the food pack about using for interim storage chilled food or frozen food.Especially for Maintain the holding temperature of above-mentioned packaging bag to close heat keeper processed, be simultaneously provided with zip for opening and closing sack, the present invention be in order to Prevent from coming off and set handle above it, simultaneously when using handle, provide convenience on using because preventing it from opening.? When manufacturing this invention, provide again the simplicity in manufacture.

Meanwhile, the bottom of packaging bag can be opened up roomy, sets surface layer bottom this, not only increases the property being prone to paste Matter, the most also also improves apparent aesthetic feeling, again can protective packaging bag.

Background technology

It is generally desirable to the freezing or various food of cold preservation keeping, as put at normal temperatures, then can cause under its freshness Fall or perishable problem, frozen food goes bad while being then melted and reduces product quality.Therefore major part needs cold Hide or freezing keeping, therefore when selling this series products, then need the packaging bag with heat insulating function.

Especially, in recent years due to the purchase form of food, the most all in the place such as large supermarket or department store, as at this When class place is bought, situation about making a big purchase in large quantities is more, and now such as popsicle, meat, seafood etc. need to be incubated the food of cold insulation, because buying After take the overlong time of family, and period causes the problems such as food spoilage at normal temperatures because of dew, it is therefore desirable to singly have cold insulation The packaging sack of function.

The most this packaging sack with cold insulation function, its purpose is to provide packaging to use, therefore needs i.e. While being easy to the most again preserve, heat-preserving function difficult to understand to be also also easy to carry while getting well and should seal.

Therefore, the synthetic resin film that major part can produce automatically foams with by the polyethylene tube for the purpose of insulation cold insulation Film uses and makes from dynamic circuit connector system for spool.

In general, this class formation, its crust employs, and not only transparency is good and its printing is strong with thermostability and volume The PET film that axle draw tension is strong, therefore its not coplanar, can possess different printing surfaces as required, and in different faces, As required, can silver-plated paper tinsel film, after another side can close polyethylene tube expanded polystyrene sheet processed, at another side, it is considered to waterproof or consider To packaging food hygiene, close the PE film making harmless material, and make disconnected heat pad, and by folded for above-mentioned disconnected heat pad After Hao, both sides heating will paste and form edge sticking veneer around, and become and be provided with interior space, to be packaged as the bag of purpose Shape.

But this system point is, when bottom is opened, it is impossible to form face, and when the thing that packaging volume is big, Not only packaging efficiency declines, and when skin packing material cannot be close to bottom packaging bag, the problem such as can tear, can also result in bag The problem that dress state is bad.

Therefore, contrast an equal amount of packaging bag recently, by internal capacity relative to setting a little louder, not only can fill a large amount of food Product carry out keeping, also can stand in ground and carry out keeping, invent for ease of process

Therefore, this class formation is, fold above-mentioned section heat pad carry out two edge joints time, comprise by the definite part of its underpart with W shape carries out the part folded, and tilts to engage, when forming jointing edge edge, by the outside of the part with W-fold, enters Row cuts, and is made as the packaging bag making bottom surface open.

Therefore, when launching this type of packaging, in packaging bag bottom, with horizontal, it is provided with bottom surface, not only can increase packaging bag Keeping consumption, also can hang down package bag and erect.

But its shortcoming is, during by above-mentioned bottom with W-fold, in the part folded, it is provided with composition surface, edge obliquely, When cutting outside it, the part folded with W shape can divide into the first angled engaging surface and the second angled engaging surface, is using Before, this type of thing can drift and separate in the lower end of packaging bag, causes affecting the attractive in appearance of its outward appearance, and meanwhile, this type of is divided into first Angled engaging surface and the 2nd tilts the part of faying face, when packaging, opens the lower end in packaging bag, simultaneously to prolapse Go out, this type of first angled engaging surface and the 2nd composition surface and the 2nd composition surface, it is easy to will be set as sharp-pointed blade-like, one is the least The heart then can hurt the problems such as the back of the hand.

Therefore, in order to solve the problems referred to above, the part that folds with W dress with skewed joint, but is tried to think and set by portion There is the part at junction surface, edge, with the direction of straight lower section, extend and tilt to engage, but the part now folded with W shape, with first While fold plane and the second fold plane overlap, because being provided with the PET film of surface layer, become the state relatively regarded mutually, and cause The problem cannot pasted mutually by heat.

Therefore to solution the problems referred to above, in the invention that former registrant first registers, fold with W shape, and by surface layer Inner side, i.e. ET film hopes that the part in face or entirety are punched out mutually, and is set to expose the part of Pasting, and makes PE series (adhered layer is every, thermosphere, final layer) exposes, and when being pressurizeed by heating, while PE series is mutually melted, can paste mutually, And while the problems referred to above can being solved, it is possible to maintain the aesthetic feeling of outward appearance.

But, because it being needed on making more cheap, produce continuously during automatic assembly line, and by wearing Hole, should expose the exposed portion of pieceable part, engages while correct position engages, but as by bottom surface When being set to W shape, the first composition surface and the 2nd composition surface can maintain correct position, because of this feature of plastic bag, and automatically producing During line, the error of produced plastic bag, during reality closes system, then can produce the biggest problem.

And keeping is freezing, cold preservation food in space in this type of packaging bag, and the opening in the above-mentioned interior space of sealing During top, general fold after use glue step etc. to paste, and in isolation is outside space, and obtain cold insulation function, problems exists In, during as being stained with in the way of stickup on top, side can produce gap, and causes sack not fully seal, and makes outside gas Stream enters and reduces cold insulation function, and especially when carrying, very portion is convenient.

Therefore, recently in the upper inner of opening of this type of packaging bag, if to be sealed into the synthetic resin zip of purpose, and Propose to make packaging bag fully seal by this zip, but constitute the system of closing for the purpose of waterproof of above-mentioned section of heat pad, at PE When pasting zip on film, the health of the most above-mentioned packaging food goes wrong, also because closing system for the purpose of waterproof grade PE film is the thinnest, and makes the process being set zip by stickup the most complicated, and the section of making hot advance capital for body, by multifilm with Between it, polyethylene foam film publishes and pastes composition, therefore, by zip, even if with the interior face thickness of the section of being equivalent to heat pad PE film is pasted, when closing processed because of PE film and polyethylene foam film, such as the adhesion of zip, than with this quasi-polyethylene When the adherence force of the PE film that expanded polystyrene sheet closes system is strong, when opening and closing zip, then PE polyethylene foam film can be caused to distort Problem.

Further, in this class formation, the upper end of drag-line sets elongated surfaces, and when setting handle, then can cause because being packaged in interior sky Between thing lower heavy, and cause distortion or the problem pulled open.

Meanwhile, for pasting this type of zip, on the top of the opening of package bag, if elongated surfaces, this elongated surfaces when opening, As under next state, during as used handle, the elongated surfaces opened because of left and right, then can cause awkward problem.

Summary of the invention

Solve the technical problem that

Therefore the present invention is as Refrigerated packing bag, it is characterised in that while can preventing drag-line distortion, set handle in elongated surfaces Under state, can be impaired prevented also from handle according to weight or fluff, and can prevent the elongated surfaces setting handle from mutually opening.

And prevent, with this type of, the instrument that opens, be changed into the structure of packaging bag for the purpose of cold insulation, can reach with letter The effect that single process also can make.

Further, being rolled over the bottom surface of packaging bag is W shape, by the hot sticky patch in face around, can reach not only in automation process Become the effect of simplicity and accuracy, also can make to set the reinforcing of the PET film of surface layer.

Solve the technological means of technical problem

To this end, the packaging bag of the present invention, including surface layer, adhered layer, thermal insulation layer, final layer lamination closes the heat insulation of the folding of system Pad, and top is provided with peristome, engages both sides and sets edge sticking veneer, when having interior space, opening in packaging bag Mouthful the inner side on top, at adjacent final layer, the primary and secondary zip being made of plastics is with corresponding position, and with a constant temperature Paste under the state that degree heats and pressurizes, set elongated surfaces in the upper end of above-mentioned stickup zip, set rectangle perforation in its elongated surfaces Portion, when as handle, for improving the tension force of handle, reinforces film in the elongated surfaces system of closing, for preventing its elongated surfaces from opening, is adding Gu film perforation exposes thermoplastic resin, when making packaging bag, edge sticking veneer is made mutually to paste.

Detailed description of the invention

Hereinafter, with reference to the appended drawings of the present invention, it is as follows that the present invention is described in detail:

First, the packaging bag of the present invention, as illustrated in Fig. 1 ~ 9, folding heat-insulated pad (100), edge sticking veneer is set on both sides (210), and while making it have interior space, while top sets peristome so that it is by peristome, cold preservation or cold is received After jelly food, setting packaging bag (200) for packaging, the laminated construction of above-mentioned heat insulating mattress (100) is, outside by surface layer (10) Constitute with thermal insulation layer (30) and final layer (40), above-mentioned surface layer (10) and thermal insulation layer (30), closed by adhered layer (20) System, to the outside exposed of above-mentioned thermal insulation layer (30), prevent moisture while thermal insulation layer (30), for prevent foreign body to be stained with or every Thermosphere (30) is impaired, and closes final layer processed (40).

In the present invention, above-mentioned surface layer (10), use the PET film being set as by thermosetting resin that tension force is strong, another at it Simultaneously, as required, when setting printing layer (11) printed by various stripeds with color structure, it is typically based on needs, for Make printing layer can easily see, increase layer native silver or make native silver according to foldable layer, and by close system in the way of, if light shield layer (50).

Meanwhile, for making above-mentioned surface layer (10) close system, adhered layer 20 with thermal insulation layer (30)) by thermoplastic PE resin, root According to T-Die construction method, by melting liquid, plated film and be located on the PET film of surface layer (10), thermal insulation layer (30) is then with making thermoplasticity The polyethylene foam film of the PE foaming of resin, by rolled form, closes system, above-mentioned final layer in the way of automatically feeding (40) then using harmless moldable resin HDPE film, this final layer (40) is also by rolled form, and with certainly System is closed in dynamic supply.

Therefore, fold and have this type of laminated construction, there is the heat insulating mattress (100) of certain area and length, by both sides, logical Overheated stickup sets edge sticking veneer (210), while the morphosis of packaging bag, in the inside on the top of peristome, The medial surface of final layer (40), by be made up of moldable resin PE molding, the zip (70) combined with primary and secondary form, and with one Fixed temperature and pressure, heating pressurization, make zip (70), dissolve the formation one of thermal insulation layer (30) and final layer (40), at table The adhered layer (20) of surface layer (10) integration, makes its hot sticky patch while fusing.

Therefore, the surface layer (10) constituted with by PET film because of zip (70) is integrated and pastes, and can prevent zip (70) Setting the film breakage of thermal insulation layer (30) when opening and closing or break out, final layer (40) uses polyethylene foam film or HDPE film.

Meanwhile, if the ET film of the thermosetting resin of surface layer (10), because its tension force is with heat-resist, prevent because of Heat and the phenomenon that deforms.Above-mentioned adhered layer (20) and thermal insulation layer (30) and final layer (40), use more low-melting thermoplasticity than PET Resin PE series, for the fusion temperature of applicable PE, while heating, can prevent thermal deformation, therefore when lamination, above-mentioned While thermal insulation layer (30) melts with final layer (40), including zip (70), and reach mutual joint.

Now, above-mentioned surface layer (10) and adhered layer (20), respectively by PET film and PE, constitute, PET film and PE, because of phase Adherence force between Hu is too low, at PET film, dissolves PE and sets adhered layer (20) with T-Die mode plated film, can reach firm gluing Effect.

Simultaneously in above-mentioned heat insulating mattress (100), in the upper end pasting zip (70), if elongated surfaces (110), in its elongated surfaces (110) setting rectangle punching portion (220), while can making zip (70) opening and closing, punching portion (220) being used is handle, up to Effect to carrying convenience.

Now, as the punching portion (220) of handle, when packaging bag produces excessive weight, for eliminating this type of punching portion (220) damaged problem, at the inner face of the above-mentioned elongated surfaces (110) setting punching portion (220), if the stiffening piece of thermosetting resin (60) closing system, this type of stiffening piece (60) with final layer (40), in the present invention, using is the PET film or nylon that draw tension is strong.

But now, because of the elongated surfaces (110) in the punching portion (220) as handle, left and right is opened, during use, because of this type of The reason opened, then can make troubles as handle, for preventing the generation of problems, in the present invention, in elongated surfaces (110) Stiffening piece (60), while constituting packaging bag, if the inner side of the part of the edge sticking veneer (210) pasted, during apertured (211), It is positioned at the final layer (40) of the PE of stiffening piece (60) inner side, while being exposed by hole (211), by this type of final layer (40), Even if when setting thermosetting resin stiffening piece (60), can prevent from being located at the edge sticking veneer (210) of elongated surfaces (110) While stickup, the problem that elongated surfaces (110) left and right is opened.

Meanwhile, in the inner side of elongated surfaces (110), as above-mentioned, when stiffening piece (60) closes processed, to elongated surfaces (110) upside of upper end, more exposes and closes system, and in the upper end of elongated surfaces, if exposing elongated surfaces (110a), above-mentioned exposing prolongs Long face (110a), uses the PE film of final layer (40), therefore, according to the hot sticky patch of PE film, is located at the upper end of elongated surfaces The edge, left and right exposing elongated surfaces (110a), while hot sticky patch, paste by adhered layer (111) and prevent it Open.

Therefore, for the punching portion (220) of handle, prevent from according to surface layer (10) and the internal tension of stiffening piece (60) producing Raw impaired while, while reinforcement effect can being improved, expose elongated surfaces (110a) when being set as, eliminate and set according to hole (211) The difficulty of position, therefore can be easily fabricated.

On the other hand, between above-mentioned surface layer (10) and thermal insulation layer (30), as Fig. 7 depending on such as setting light shield layer (50) time, Can prevent exterior light from penetrating into sack, now light shield layer (50), should be by aluminum material vacuum layer.

Further, for this type of heat insulating mattress (100) embody color or performance publicity literary composition, advertisement literary composition etc., should be emerging in heat insulation The form on the surface of pad (100), if the another side of the PET film of surface layer (10), if printing layer (11), more should be on surface Layer (10) sets the previous stage of light shield layer (50), at the another side of surface layer (10), carrys out print advertisements with magazine printing etc., a surname Pass sentence, and guarantee the vividness according to light shield layer (50).

Therefore at the another side of the PET film setting the transparency surface layer (10) relatively high with elongatedness, print advertisements, a surname Pass sentence and prevent the problem impaired according to print contents such as frictions.

Meanwhile, it is being provided with the elongated surfaces (110) in the punching portion (220) used with handle, when closing stiffening piece processed (60), is examining Considering to surface layer (10) and stiffening piece (60) is identical material, when overall conjunction is processed, makes troubles when causing carrying because of really up to the mark, because of This closes system in the way of dispersion point-like, while its pliability not only can be kept to have also can ensure that flexibility, can reach firm conjunction The effect of system.

Simultaneously for eliminating the problem opened, set edge sticking veneer (210) in elongated surfaces (110), only in stiffening piece (60), if Hole (211) or expose elongated surfaces (110a), after making PE material (foldable layer, thermal insulation layer, final layer) all expose, heating same Time, if pressurization, while PE series is mutually dissolved all or in part so that it is mutually paste, make to set the elongated surfaces of handle (110), firmly paste, can prevent from being prone to, because of too strong external force, the problem opened..

And set the surface of above-mentioned PET film (10), dissolve PE with T-Die mode plated film, if PE film plating layer (1), and can be true While protecting the flexibility of surface layer (10), useless gloss can be eliminated the making being prone to as opening bottom surface is provided.

Now PE film plating layer (1), its coating film thickness should be with the thickness plated film of 10 ~ 30, because its characteristic is molten at 105 ~ 110 DEG C Changing, at the PET film of the surface layer (10) setting heat insulating mattress (100), under the state of plated film, the roller in side constitutes cooling line, And made cold rolling while, with equilibrium thickness plated film while, can reach the purpose of cooling.

When being less than 10 such as coating film thickness, when closing processed, the problem that can cause correctly pasting.For another example with 30 with On thickness plated film time, then cause the generation of break-off.

As above-mentioned, the heat insulating mattress (100) of PE film plating layer (1) will be set, after rolling over for half, be the heat insulation of W shape by playing lower end folding When the right and left of pad (100) heats, rolling over the part (a) for W shape, the part (b) being half with folding together folds, because setting edge Sticking veneer (210), because of the taping process of one side, while making the packaging bag (200) that bottom surface is opened, not only makes its bottom surface wider Ground still prevents it while opening and waves, and can reach the effect of correct stickup.

And by PE film plating layer (1), it not the form with film, but after making PE dissolve in the way of T-Die, and plate While film, not only can save raw material, it is not required that particularly paste medium and also can reach the effect of stickup.. will be heat insulation Pad (100) folding is half, and sets to constitute the edge sticking veneer (210) of packaging bag (200).During because pasting, the face hoped mutually, all with PE, because being identical material, without alite paste, and only by heat, it is possible to reach the effect pasted.

And it is provided with PE film plating layer (1) in the upper end of packaging bag (200), it is set to the elongated surfaces of handle (110), because of This is when packing overweight thing with packaging bag (200), such as because of carry overweight thing cause packaging bag (200) sagging time, Handle can be reinforced and prevent the problem fluffing or distorting.And set up silver at the back side of the PET film of above-mentioned surface layer (10) The light shield layer (50) of foil matter, it is possible to reduce the change of the external temperature impact on the cold insulation effect of packaging, at this type of native silver material On the light shield layer (50) of matter, make and have expanded polystyrene sheet.When being provided with light shield layer (50), the only packaging for the purpose of insulation Bag is made with stickup in the same way before.
