Description

1326666 IX. Description of the Invention: [Technical Field of the Invention] The present invention provides a composite film and a manufacturing method for a gas-tight food heating automatic pressure regulation, which are mainly used in various food packaging boxes or bags. After cold, chilled food and sealed tightly, the microwave heating process can partially adjust the generated high-temperature circulating steam to break the granules and avoid the rupture of the package or food box. High = Vapor does not cause a large amount of loss and maintains a delicious food. (, automatic (four) packaging [previous technology] Since ancient times, 'food cooking is mostly based on fire, high-temperature water or base, the way to cook, and use high-energy efficient microwave heating or ', cooking food so far It has a history of more than 50 years. Among them, countries with higher industrialization's use of microwave ovens and heated foods in general households, schools, restaurants or other public places are also high under the convenience and speed of appeal. (Microwave)'s principle of heating food is to use the dipole moment nature characteristic of the polar molecules of each component in the material to be heated, and to excite the magnetic field in the microwave electromagnetic wave vector field, so that the vibration or the rotary motion occurs. By its own damping (DQ action = vibration energy of the dipole moment is converted into heat energy by friction dissipation ((10)): the internal system & energy 3: accumulation and warming in the body system causes the temperature of the system containing the material to rise, In general, the higher the dipole moment strength or the higher the dlelectricconstant value of the material composition, the more the electromagnetic wave energy is converted. 326,666%

The higher the ratio of Git, the better the material heating effect and the faster the heat. The relative dielectric constant value of pure water is close to 80 at room temperature, and the value of the electric spoon constant is "A? at room temperature." In the door of the agricultural materials of Juyi:: The water-containing food is coated with Daegu Ba x #中同夸heated under microwave electromagnetic field. In theory, the Γ can be converted from heat to heat. In other words, the low temperature is based on food, and the material is low. Its own material heats up less. Penetration characteristics, which can penetrate into the material... - The wide skin has a general electromagnetic wave: vibration and damping (Damping) make the heating and heating effect better, and the industrial quality is better. The equipment of the article is used for twisting, dry-drying, 1, and the use of microwaves in the city's %. When using ά/P, dry 'cooking, baking and sterilization, etc., the electromagnetic wave is 915. 'In addition, the relative median value of food materials, temperature and microwave frequency during microwave heating are related. The rapid loss of moisture and drying hard are two major problems often encountered in the cooking process of food. This heating and cooking constants and high volatile components (such as water) ^ two from the food inside the high in the microwave field will be able to The microwave electromagnetic wave energy has = 丨; the constant temperature of the material is used to cause high volatility and gas qi to be converted into heat energy, and the volatile volatility is externally transferred to make the food dry and hard, and loses = the component is susceptible to heat and is faster than microwave heating. In the application market, the use of packaging materials has a fresh-keeping 瞑 (;: π is more common in microwave ovens, etc. The use of the package material composition furnace canisters only include polyethylene (PE), 6 1326666 1 Polypropylene (PP), polyamide (nylon), polycarbonate (pC), polyethylene (PVC), polyvinylidene oxide (PVDC), polymethylpentene (PMP), ethylene Ethylene-vinyl acetate (EVA), polyurethane (PU) or SurlynTM (trade name of Dupont ionomer), polyethylene terephthalate (PET) ), P〇丨yvinyl alcohol (PVA) , paper, synthetic paper, cellophane • ( cel l〇phane ), ant paper, ceramic (ceramic), glass, etc. The combination of materials, material structure, can be a single structural layer, composite multilayer structure, foaming Structure, etc. In practice, in order to facilitate the manufacture of such packaging materials, the packaging industry will add some plasticizers to the packaging product process. Therefore, the additives on the food package will be in the food package _ acreage = heating or microwave heating During the cooking process, because the food is often smashed!:: and the food is contaminated and damaging the health of the body. Health and health: standard: Bureau 2 == FDA) The second is = there is - the more the packaging material is added to the high 4 material shake, but also the specification of cracking. ', and, 'the characteristics of the dish and the low-temperature, high-temperature environment, the cattle, because of the high energy efficiency of the microwave oven, the ^ and the level of the face is greatly improved, the acceptance is relatively improved. How to convenience and speed, such as the characteristics of not losing and retaining the original taste, ^ two, in the conditioning process, camp,, ' ° microwave heating and steam cooking 7 1326666 35 $ σσ seems to have become a - stock style ' This is a rapid cold; East organic vegetables and fresh frozen vegetables in the cooking application can fully retain a variety of vitamins after the ingredients, seal 4 foods using microwave heating ..... Ba Yi Town, typhoon seal empty inside the fast The phenomenon of warming and high heat steam pressurization causes the bag to burst.

In order to avoid the phenomenon of gas explosion, the general food packaging provides Weishang's recommendation. Before using the microwave to heat or cook the food, an opening must be reserved on the packaging bag or the dish to make the high temperature generated during the heating process. The gas can be pressed, : Free: fried. The microwave ovens produced by Zlploc in the United States are used to teach the user that they must be opened by the bag before the microwave oven is used - venting holes to avoid explosions and accidents. Such an application makes the food subject to the microwave heating process in an open space, and the volatile components in the food are largely lost due to heat during the heating process, resulting in food: drying and delicious, #然此-reserving the open-mouth package U In the air, oxygen is exposed to the 'microbial strains', and the cockroaches and insects are also prone to k 'Pc cm. Not the United States: ^ In addition, when you want to heat the cooked foods related to flour, Italian noodles (talking hettl) f, the general use of the package; gas 8 1326666 f (steam cooker) or food coated wrap film after using the microwave oven Progress = force J heat. Although the result of the food can be obtained, but when the water is too much, the flour 2: there will be swelling or smashing (s〇ggy); while the latter coating the plastic wrap can save time, but the food is heated by microwave. The internal moisture will be quickly lost to the outside. Because the plastic wrap is impervious to water and its low dielectric constant material' characteristics, the microwave energy conversion rate of the microwave energy is higher than that of the electric coefficient. The food material is low, and the temperature of the wrap film itself will be low, so this extra water vapor will condense at the interface between the food and the plastic wrap, causing the food covered by the wrap film to be smeared (s〇ggy). The phenomenon of uncovered parts has become dry and hard, which makes the food unsavory. In order to prevent the food packaging materials from being heated in the microwave heating application, the problems of heating and rising gas explosions have occurred. So far, the research and development work is ongoing, and many different kinds of gas permeable materials have been developed, but most of them are concentrated in Waste water filtration, air purification filtration, paper diaper permeable moisture, wet paper towels, breathable medical supplies, etc., but are not suitable for food packaging microwave heating technology applications. One of these conventional methods for producing a gas permeable material, such as U.S. Patent Nos. 3, 378, 507, 3, 310, 505, 3, 607, 793, 3, 812, 224, 4' 247' 498, 4' 466' The techniques disclosed in 931 and 5, 928, 582, including the formation of a film by using incompatible materials, and then using an extraction method to dissolve a certain component to form a pore-like structure, such a gas permeable material is mostly used for filtration. Separation membrane (separat〇r) with separation of electrolytes in the battery, and separation of dialytic film for pure water purification or seawater desalination due to the separation of the material (filtrati〇n and separati〇n) Mechanical strength and porosity are inversely related, the material is applied in microwave food package 9 1326666

In the application, there is an explosion phenomenon in the process of microwave heating, and the residual unextracted (4) Duoji Temple, in the microwave heating process, the microwave energy is converted into heat energy due to the high electrical constant value itself. (heat) process forms heat sp〇t and causes the packaging material to be partially dissolved by heat into pores. The volatile components in the food are thus lost. The material is not suitable for microwave food packaging materials and is extremely expensive to manufacture and is extracted. The solvent recovery process is complicated. Another type of gas permeable material, such as the technique disclosed in U.S. Patent No. 5,865, utilizes a nonwoven fabric or a fiber cloth having a gas permeability f. However, these methods all make the gas permeability (4) have the characteristics of macropores (P10s), and are mostly used in paper diapers and wet tissues, and are used for microwave food packaging and are extremely expensive to manufacture. A method of producing a gas permeable material, such as the technique disclosed in U.S. Patent Nos. 3,679,54, 4,187,390, 4,35, 655, 4,466, 9314, and 5'340,646, by means of inorganic material powders, such as carbonic acid. (CaC〇3), titanium oxide (Ti〇2) or oxidized (a(6) is blended into an organic polymer material such as polyethylene bake, and then extruded into a film. The pot film forming method includes using a concentric die (die) extrusion shot square ^ cylindrical pull bag or blow bag, extension stretcher (tente〇 stretch, or injection, etc. then 'below or near the softening point of the material ^ do thin stretch Extension processing. Although such a manufacturing method can produce = micr〇P〇rous, the manufacturing cost is too high, and the products of this type are not practical, and there is still no right, ji^, and a chicken. Seeing moxibustion, (4) Μ #, ",, there are Qs that explode in the wave heat history, and the inorganic salt additives added in the eight are mostly - low specific heat and higher dielectric constant materials, in a heated environment It is easier to form the heat spot of the 1326666 part of the bureau to melt through the packaging material.值得注意. It is worth noting that this manufacturing method will result in the quality of the gas permeable film not being - 'such as stretch rate, processing temperature, film thickness and raw material distribution; etc. will lead to hole size is not - and additives The use of the subsequent environment is different, for example, may cause environmental problems. In addition, it is limited by the film material. Selective, and often caused by the multiple phases of the additive, the film is often not formed after film formation. It is transparent and needs to be stretched. In addition, when such a gas permeable material is applied to food packaging, there is a concern that the additive contaminates the packaged food, causing unpleasant odors. When oil or alcohol is used, it does not effectively block oil and alcohol. Therefore, it is impregnated with oil and alcohol due to capillary adsorption. The further effect is when the gas permeable membrane is applied to the food and contains an oxygen scavenger inside. In the case of pouch, the oxygen scavenger component is contaminated by oil and alcohol and cannot maintain the function of keeping the food fresh. General food is heated or The cooking process is a kind of heating process. When the microwave is directly heated by the microwave oven, the microwave heating often uses the high dielectric constant component such as water contained in the food to effectively utilize the microwave co-vibration effect and the damping property of the material itself (damping property). The microwave energy can be converted into heat to heat or cook the food itself, so that the microwave heating process causes the water temperature to rise and the internal vapor pressure to increase, because it itself contains low specific heat characteristics, when the gas permeable membrane is used to package food. When the material is heated in the microwave, it is easy to generate hot-spotted jheatingspot in a short time concentrated heat, and melting into a larger hole' causes the gas-liquid external vapor in the package to be more powerful, and in addition to the loaded articles and high temperature. Sterilization 1326666 Process makes this breathable film easy to peel off. The bag body continues to develop and produce food packagings or slings that are prone to blasting problems, in order to introduce a variety of gas-permeable food-packing boxes or bags, so that the film does not need to be opened separately. Layer;::= and m乍 microwave heating

3 or the clothing of the clothing is effective for a short period of storage, because it is usually unable to perform the direct cracking or by changing the packaging environment of carbon dioxide (carbonl (Dxlde, (10)), nitrogen (five) and other inert gases (modified atmosphere

The Packaging, MAP) process is used to extend the shelf life of foods. In addition, during the long-term frozen storage period, it is easy to freeze and dry due to the moisture of the food, resulting in ice burn. In addition, the inventors have been making improvements to the packaging bag or the box for food microwave heating, wherein the related core technologies are disclosed in Taiwan Invention Patent Nos. 153042, 172945, 182938, 201 962, and US Invention Patents No. 7077923 and 7208215 , Japanese Patent No. 3747004, etc., the gas permeable composite film material as a food microwave heating packaging bag can improve the shortcomings of the conventional gas permeable material and provide convenient operation and use characteristics, and at the same time ensure the microwave heating process, food The contained water is retained in large quantities and the juice it contains does not splatter in the microwave oven' to reduce the cost of time-consuming cleaning and water wastage. More importantly, this reversible automatic gas permeable pressure regulating function package I material is in a closed structure before microwave heating; during the heating process, the high temperature hot vapor pressure that the packaging material itself can carry can be automatically adjusted to avoid the bursting of the packaging material. When the cooling is stopped during microwave heating, the material will return to the closed structure. This reversible structural property associated with pressure temperature makes the 12 1326666 material reusable, and this single or destructive microwave package for bagging or slitting-opening differs. ~, (4) The method is extremely [invention] The present invention is to further improve the food packaging or bag body currently used as microwave heating, in order to cope with the body or the bag body, at a low temperature in the normal temperature plate...
