At least one of said two film layers has a layer of directionally extended film, and an air-tight automatic pressure regulating region in air permeable mode, in which there are multiple sealed microgap structures. Its making method is also disclosed.
Description
Technical field
The present invention relates to a kind of vacuum packaging that applies to various food, and can be to partly crossing the microwave heating available vacuum-packed bag, and fabricating method that vapor pressure is regulated in microwave heating process.
Background technology
Traditional sealed packed food material adopts the low plastic film of permeability to air to make mostly, in heat process especially in the microwave heating process, normal because of steam rapid temperature-raising, supercharging in the seal cavity, the permeability to air of packing own is not enough with intensity can't support and cause the unavoidable in essence gas explosion of packaging material for food (bursting).For avoiding this phenomenon, the normal food packing provides manufacturer all to advise, before the heating of use micro-wave oven or the food that boils, packaging for foodstuff bag or box body must be opened an opening, make the heating high temperature and high pressure gas that is produced in the process that boils be able to timely adjustment pressure, avoid explosion phenomenon.U.S. SC Johnson company all instructs its user zippered bag must be opened a ventilative opening before micro-wave oven uses, to avoid blast phenomenon and accident on the packaging for foodstuff Mi Baonuo of the freezing special use of its production (Ziploc) zippered bag.
But this occupation mode can make the food in the microwave heating process be in an open space, and volatile component such as water or effumability seasoning thing can be because of a large amount of losses of being heated in heat process in the food, causes food to become dry firmly and loses delicious food.Another emphasis is that the Ziploc zippered bag adopts polyethylene (polyethylene) material to make through the extruding inflation film manufacturing machine mostly, and this kind material belongs to a kind of and has the high and low mechanical strength of gas barrier performance, and at high temperature has very high ductile material.Food is heated under air-tight state in the Ziploc zippered bag, for example heats in micro-wave oven, very easily can't bear higher temperatures because of material itself in heat process and vapor pressure causes the gas explosion phenomenon.In addition,, very easily the high temperature place is melted broken and be in ventilative fully state, cause food become dry (dehydration) firmly because of temperature distributing disproportionation is even because its material melting point is lower.Therefore, industry continues the packaging for foodstuff bag or the box body of traditional easy generation explosion problem are researched and developed and produced, release the packaging for foodstuff box body or the bag of multiple tool permeability to air, satisfied the requirement that packing is freezing, chilled food does not need to open separately rete when microwave heating.Yet, shorter with the shelf life storage that the packaging for foodstuff box body or the bag of this tool permeability to air are packed, usually can't adopt vacuum packaging or filling arbon dioxide (carbon dioxide, CO2), nitrogen unreactable gass such as (N2) changes package, and (modified atmosphere packaging, method MAP) prolongs the food fresh keeping phase to environment.
Other has disclosed notification number is " packaging bag and manufacture method " invention case of 522123, the permeability to air composite film material packaging bag that microwave heating is used as food that it provides can improve the shortcoming of known breathing material, and has a more convenient characteristic of manipulating, more can guarantee in microwave heating process simultaneously, contained moisture can be heated splash in micro-wave oven by the juice that keeps in a large number and contain in the food, reduces cleaning consuming time and water resource waste cost.The more important thing is that this has the invertibility food microwave heating packing of ventilative voltage regulation function automatically, before microwave heating, be in air-tight state, but the excess steam pressure (over pressure) that can bear of automatically regulating packing itself again in heat process is avoided packing explosion in heat process.And when termination microwave heating was in cooling process, this material can return to original closed structure (normallysubstantially closed structure) again.The invertibility structure that this kind is relevant with pressure and temp, the switching characteristic that it has makes this material have reusable characteristic, and the destructive microwave heating occupation mode of single that need open food pack in advance with the Traditional Packing material or sever an opening has very big difference.
In addition, pack zippered bag as this material microwave heating with the ventilative automatically voltage regulation function of the invertibility of embodiment, comprise a rete, have a plurality of microcosmic interstitial structures on all or part of area of rete, also be provided with a zip strip on the rete, this rete is can be by the material layer of heating or super sonic mode and chain combination.Before food microwave heating, zip strip group on the microwave zippered bag needs complete driving fit, so can make High Temperature High Pressure vapours that microwave heating generates fully samming, in bag, circulate apace, and unlikelyly leak in a large number and waste energy, so this zippered bag can also shorten the food required time that boils except effectively using the energy.
But the food pack that above-mentioned microwave heating is used still has the space of improvement.For example normal food packaging bag for saving the storage area and prolonging the food fresh keeping time limit, is adopted vacuum-packed mode usually.Traditional nylon vacuum packaging bag can only carry out the vacuum type packing with the higher railway carriage or compartment type vacuum for industrial use wrapping machine of cost, and can't use desktop easy to carry or hand held suction nozzle formula vacuum suction capper to reach the food vacuum packing, also can't adopt the microwave heating of direct hermetic type simultaneously.And can't carrying out food vacuum with desktop or hand held suction nozzle formula vacuum suction capper too, packs the microwave package that notification number is " packaging bag and manufacture method " invention case of 522123 to be provided, make its use be restricted, especially in the family use is very limited, and can't use the desktop vacuum sealer of general family expenses to carry out the food encapsulation expediently.

Use of the present invention is implemented, and as Fig. 9～shown in Figure 11, after inserting food 70 in the microwave heating available vacuum-packed bag 50, vacuumizes also freezing sealing up for safekeeping behind the heat sealing with desktop vacuum heat-sealing machine 60 from sack.When the cooking is edible, do not need to open or tear this microwave vacuum bag, can directly adopt any type of heating to cook, as microwave heating, steaming is cooked a meal or poach all can.As with the microwave heating cooking, can directly place micro-wave oven to heat from the reach in freezer taking-up.Vacuum packaging bag 50 in-to-in food 70 are in the process that is subjected to the microwave heating cooking, food 70 in-to-in moisture can be converted to heat energy with microwave energy and be heated and heat up and produce gradually simultaneously and disengage the High Temperature High Pressure vapours, when steam pressure is too high, its partly vapours can regulate overvoltage (regulate the over pressure) by the microcosmic interstitial structure 15 in pressure regulation district automatically, prevent to produce gas explosion also can be preferably to food preserve moisture, fresh-keeping.After the cooking, the microcosmic interstitial structure 15 on the vacuum packaging bag 50 can revert to original closed structure (normally substantially closed structure) in essence, with the problem that prevents that extraneous bacterium, foreign matter or small worm from invading.
In addition, the ventilative automatically pressure regulation plot structure of the air hermetic that has in the vacuum-packed bag material of microwave heating among the present invention, in PCT/CN2004/000188 patent application before, disclose, it comprises a base material rete and another the airtight involution rete on it, have most microcosmic interstitial structures (normally substantially closed micro-gap structure) 15 on the automatically ventilative pressure regulation base material rete on this base material rete, as Figure 12～shown in Figure 14, last slot 151 (upper seam portion) has one with its surface and is close to similar ridge marginal texture 153 in pairs, and be combined into a similar line with the following slot 152 (lower seam portion) of a closure and split structure (crazestructure), following finedraw closing structure wherein is that interface, adjacent two edges is in contact with one another to lump together and forms a hermetic type microcosmic interstitial structure 15, it has the structure that is tapered to last contact closure by last slot 151 end faces to following slot 152 bottom surfaces along thickness direction, and microcosmic interstitial structure 15 neighboring edges belong to physics closed contact and leakproofness (physically contact to each other and normally substantially closed) in essence.In the microwave heating process that is applied to food pack, this is the finedraw closed structure down, be not heated or the microwave heating starting stage, when the vapor tension that food is produced by microwave heating in the microwave bag is big inadequately, interstitial structure 15 initial conditions are closed, when microwave heating continues in the process of carrying out, build up the rising effect and extend gradually and strut microcosmic interstitial structure 15 because of being subjected to press in airtight, avoid the gas explosion phenomenon to regulate partly excessively interior the pressure, importantly, when the pressure that acts on these film two sides in microwave heating process has a difference of pressure, as Figure 12～shown in Figure 14, rete 100,200,300 begin to expand and along the film surface direction, are subjected to surface tension effects and extend stretching, microcosmic interstitial structure 15 on the film also begins along under the effect of tension force on the film surface, becomes to part a little and have permeability to air gradually.It should be noted that, closed gradually line splits structure in heating gradually pressurization on this structure, press by regulating in the elevated temperature heat steam too high in the bag of a small amount of vapours from inside to outside through mechanical mobility, so can avoid the explosion of packing, and the inner most moisture of food will be retained down in heat process, simultaneously in microwave heating process, vapor tension in the bag also can maintain and be higher than the atmospheric pressurization state that boils, and this high temperature, high pressure cooking environment help the acceleration prepared food effect of food.The ability of the extension of microcosmic interstitial structure 15, the adjusting Air permenbility that amount of tension had height and the relation of the big or small proportional example of interior pressure of being born, after the difference of pressure disappearance that acts on the film, the microcosmic interstitial structure 15 that becomes air-permeable structure because of differential pressure action will be replied gradually again and will be that original airtight air impermeability structure, the microcosmic interstitial structure of the crack and arrangement for closed configuration that this kind is special are reversible type design.With the food in the micro-wave oven heating microwave bag is example, moisture is under microwave heating action, produce an elevated temperature heat vapor tension in closed bag inside gradually and act on the film with difference of pressure by its association, when the bag internal pressure be higher than the bag outside a barometric pressure time, this difference of pressure acts on slot bottom surface 14 and up slot end face 12 pressure stretch under the automatic voltage regulation film, the microcosmic interstitial structure of closing 15 beginnings are extended along the direction parallel with the film surface widen and gradually open, the interstitial structure 15 of first half rete also begins to enlarge simultaneously.This kind extends open structure because of the difference of pressure effect and can be used for regulating the high-temperature steam overvoltage (over pressure) that produces (build up) in (regulating) microwave heating process in the microwave bag, so can avoid the gas explosion of rising.
It is explosion-proof with adjusting overvoltage (regulating the over pressure) that the present invention also has high pressure cooking effect simultaneously, and its principle is identical with pressure cooker (pressure cooker).In the vacuum-packed material, the involution rete of vacuum tight is provided, can cover a side with a plurality of microcosmic interstitial structures zone, the involution rete by another adhesion layer through the dry type manufacturing process of fitting, or by sticking together liquid coating, dry and applying manufacturing process or hot melt adhesive applying manufacturing process, be linked to base material rete with a plurality of microcosmic interstitial structures zone, make last composite film make food vacuum packaging bag airtight fresh-keeping formula packing for the saving space under general room temperature or chilling temperature simultaneously in conjunction with being applied on the food airtight vacuum packing.In the microwave heating process, the high temperature of involution rete that contains adhesion layer because of being subjected in heat process, to be produced from the packaged food content, high pressure steam penetrates the base material rete with most microcosmic interstitial structures zone, act on simultaneously on the adjacent adhesion layer and make it deliquescing, and viscose glue is behind contact high-temperature water vapor or oil vapour, the adhesion material surface is lost stickness and separation automatically gradually, in microwave heating process, form a ventilative channel, make the automatic base material rete with most microcosmic interstitial structures zone of breathing freely pressure regulation district (self-ventingarea) that is close to involution rete below bring into play its automatically regulating high-temperature steam simultaneously and cross compression functions, make composite film have a scalable packing device, avoid the function of gas explosion in the high temperature vapor pressure that heat process produced.
