Description

522123

The present invention relates to a food & and to a temperature-dependent application and manufacturing method. Since ancient times, cooked food has been available up to now. In other public-field microwave electromagnetic wave materials, the cooking of most of the electromagnetic waves that vibrate or rotate the polar moment is mostly cooked by fire, and the use of high energy efficiency exceeds 5 0 years of history. Among them, with the speed and speed, in a microwave oven to cook and add (Microwave) heated food, the polar molecules themselves have a field in order to align with magnetic motion. The material can be converted into, heat-cooked or steamed by microwave to dissipate by its own resistance. The microwave is used for heating or cooking, and the households, schools, restaurants or hot foods in countries with a higher degree of industrialization also have a higher ratio. The "right principle" uses the intrinsic characteristics of the heated dipole moment in the micro electric field. As a result of the intense Damping effect, the dipole heat is generated and the internal energy energy in the overall system is accumulated and warmed, resulting in a system containing materials. As temperature rises, generally speaking, the higher the dipole moment strength or the higher the relative dielectric constant of the material component, the higher the ratio of converting electromagnetic wave energy to thermal energy, which means the better the material's heating effect and heat Speed

Faster. The relative permittivity of pure water is close to 80 at room temperature, and the permittivity of polyethylene is 2.51 at room temperature. Therefore, water-containing food is coated in polyethylene packaging materials while under microwave electromagnetic fields. Heating, in theory, most of the microwave electromagnetic energy is converted from water to heat energy. In other words, the heating and heating in the heating system is mainly food, and the packaging material has less heating due to the low heat conversion ratio. In addition, microwaves have the penetration of general electromagnetic waves

Π :: η heating the object in any corner of the mass, and dissipates with damping (Damping) into the original thermal energy and makes it within the system: > :: ^ The higher the knife damping heat conversion efficiency, the better the temperature effect. The better. The better the product, the better the fruit. 'In the industrial and consumer markets, microwave equipment, π port for heating, drying, cooking, baking and sterilization are often used. The heating microwave frequency used is 915 million Hz. (〇2) and 245 million million hertz = (MHz) electromagnetic waves, in addition, the relative dielectric constant value of food materials and microwave heating temperature and microwave frequency are related. The rapid loss of water and the drying and drying of food are two major problems that are often encountered in the process of using microwaves to enhance food quality. This is due to the high dielectric constant and high volatile components (such as water) in the food, which has a high dielectric constant. The material composition can convert microwave electromagnetic energy into heat energy in a microwave field. This temperature rise causes high volatility and south vapor pressure characteristics of the material composition to be easily heated and rapidly volatilized and transmitted, which makes the food dry and hard and loses its deliciousness. In the microwave heating application market, the more commonly used packaging materials for microwave ovens on the market include cling film (wrapfi 1 m, microwave bags and trays, etc.). The raw materials used in the packaging materials include polyethylene (p E), Polypropylene (PP), polyamide (nylon), polycarbonate (PC),

Polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polymethylpentene (PMP), ethylene-vinyl acetate (EVA), polyurethane (PU), or SurlynTM ( Dupont ionomer (brand name of ionic polymer compound), polyethylene terephthalate (PET), polyvinyl alcohol (ρ ο 1 yviny 1 a 1 c 〇h ο 1, PVA), paper, synthetic paper ,cellophane

522123 V. Description of the invention (3) (cellophane), wax paper, ceramic, glass, or a combination of the above materials. The material structure can be a single structural layer, a composite multi-layer structure, a foamed structure, etc. In practice, in order to facilitate the manufacture of such packaging materials, the packaging industry will add some plasticizers (p i a s t i c i z er additives) in the process of packaging products. Therefore, the addition of swords on food packaging materials will often cause direct contact with food packaging, storage, transportation or microwave ovens, and cause food artifacts. In view of this, the U.S. Food and Sanitation Regulatory Commission has indicated a trend for food packaging materials. In addition to the requirement that food should not be packaged, the temperature resistance of packaging materials used at high temperatures. In recent years, due to the general consumer's knowledge of the high energy efficiency of microwave ovens, the degree of cooking has also increased. Therefore, finding the same humidity, low cost and easy to use has become the current food packaging industry. In addition, sealed packaged foods use microwaves to rapidly warm up and pressurize. The high temperature and high pressure weather produced in the packaging bag or pan. The United States Ziploc company in the production of hot cooking process, because of food contamination and health hazards (FDA) and domestic health requirements and restrictions have become increasingly stringent packaging materials pollution, but also increased Specification of low temperature and high temperature cracking. The knowledge and economic standards have been greatly improved, and the acceptance and development of features such as thermal convenience and speed are applicable to different temperature, non-microwave special food packaging materials, and we have considered the goals of improvement and hard work. When heated, it is often caused by gas explosion in the sealed bag. In order to avoid gas explosion, it is recommended to use a microwave oven or an opening on the jewellery to release pressure from the heated cooking body and avoid microwave cooling when the explosion occurs;

522123 Fifth bag micro Invention description (4) = on the bag 'teaches that the user must leave the ‘:: vent hole to avoid explosion and accidents before using the microwave oven. Such an application puts the food subjected to the force ^ ',,, and overlying food in an open space, and the volatile components in the food are beautiful. A large number of them are lost due to heat during the process, causing the food to dry and lose its cause. Whether the food packaging bag is completely sealed or detachable plus a jacket 3 = In a closed packaging space, if placed in a microwave oven type: the critical tension that can withstand is strong 1, and the food is exploded ^ ▲ material At 1 o'clock, a large amount of water vapor is lost and the food is dehydrated and becomes no longer. 'When you want to heat cooked flour-related foods, spaghetti, etc., the general method of use is two sons and two meals? After steam cooker) or food wrap ^ use a milk oven. Although the former can get the result of gourmet, but the absorption of the convection oven for the addition may cause swelling or bluffing; while the latter is covered with & excessive flour food :: the product is heated by the microwave, the water inside is fast J can save time, ΓΓ!

Only the packaging materials are heated in the microwave.

522123 V. Description of the invention (5) The problem of the explosion of warm air has occurred 'early to date, research and development work has continued, and many different types of breathable materials have been developed, but most of them focus on wastewater filtration, air purification filtration, Paper diapers are hygroscopic, wet paper towels, breathable medical supplies, etc., but they are not suitable for microwave heating applications of food packaging. One of these conventional breathable materials manufacturing methods, such as U.S. Patent Nos. 3, 378, 507, 3, 310, 505, 3, 607, 793, 3, 812, 224, 4, 247,498, 4, 466, 93 1 The techniques disclosed in Nos. 5, 928, 582 include the use of incompatible materials to form a film, and then using an extraction method to dissolve one of the components to form a hole-like structure. Such breathable materials are mostly used in filtration and Filtration and separation, such as the separation membrane (separat 〇r) in the battery that allows the electrolyte to flow and the isolation dialysis membrane (dia 1 yticfi 1 m) for pure water purification or desalination, due to the mechanical strength and pores of the material layer There is an inverse relationship between the degree and the application of this material to microwave food packaging applications. When the microwave heating process has an explosion phenomenon and the remaining unextracted material is too much, the microwave heating process is liable to have a higher dielectric constant. A constant value is formed during the conversion of microwave energy into heat to form a heat spot, which causes the packaging material to locally melt and penetrate into holes. The volatile components in the food are thus lost in large quantities. Material is not suitable for microwave food packaging and high manufacturing cost and complicated procedures extraction solvent recovery. Another type of breathable material, such as the technique disclosed in U.S. Patent No. 5,8,65,9,26, is to use a non-woven fabric or a fiber cloth having breathability. However, these methods will make the breathable film have macro porous characteristics. Most of them are used in applications such as paper diapers and wet tissues. They are not suitable for microwave food packaging and have extremely high manufacturing costs.

522123 V. Description of the invention (6) There is also a conventional method for manufacturing breathable materials, such as U.S. Patent Nos. 3,679,540, 4, 187390, 4,350, 655, 4,466, 931, 4 777 073, and 5, The technology disclosed in Case No. 34 0, 64 6 uses inorganic material powders, such as calcium carbonate (CaC03), titanium oxide (Ti02), or aluminum oxide (A12〇3), to be mixed into organic polymer materials, such as The polyethylene is then extruded into a film. The film forming method includes a method of using a concentric circular die (d i e) extrusion injection method to obtain a column pull bag or a blow bag, an extension tenter (tenter) stretching, or extrusion injection. Next, the film is stretched and stretched at a processing temperature below or near the softening point of the material. Although this manufacturing method can produce micro holes, the manufacturing cost is too high and the difficulty is high. At present, ancient products are not practical, and there are still explosions that occur during microwave heating. Similarly, the Most of the added inorganic salt additives belong to a kind of material with low specific heat and high dielectric constant. 'It is easy to form a local heat spot in a heated environment, which may melt through the packaging material. It is worth noting that this manufacturing method will lead to inconsistent quality control of breathable membranes, such as elongation rate, processing temperature, film thickness, and raw material formula, etc. will cause inconsistent hole sizes, and the use of additives will affect the subsequent environment Differing, for example, may cause environmental issues. In addition, it is limited by the selectivity of the thin film material, and the film is often not transparent after the film formation due to the multi-phase combinations of the additives. Furthermore, a stretching step is required. In addition, when such a breathable material is applied to a food package, there is a concern that the additive may contaminate the packaged food, causing unpleasant odors. When this kind of breathable film comes in contact with food containing oil or alcohol, it cannot effectively block oil and alcohol, so it will cause impregnation due to capillary adsorption ^

522123 V. Description of the invention (7) Oil and alcohol content, the further effect is when it should be installed and contains a small bag of oxygen scavenger (po 'permeability film is wrapped in food bag and stained without ... keep two deaerators : You Genkou belongs to the heating or cooking process-:: 工 ， 月 agger〇 When the microwave oven is directly heated, microwave heating is often used; :::: 2 Cooking food itself, "Microwave heating has been done for two times ::::: The air pressure increases greatly, and 0 itself has a low specific heat characteristic component. ^ When this film is used to package food, the material is heated in the microwave, so it is easy to generate hot spots (heating ^ pot, and Melt into a larger hole, causing the gas and liquid in the package to leak more, and in the process of filling items and high temperature sterilization, the breathable film is easily peeled off. Therefore, the main object of the present invention is to provide A breathable material, and a manufacturing method and application thereof, for improving the shortcomings of the conventional breathable material and 1 ° According to the purpose of this volume, a breathable material for food packaging bags is proposed, including a film layer and a child film. There are several cracks on the surface. The geometry of the cracks can be of various shapes. The average size of the cracks is between 0.05 mm and 3 mm. Another layer of synthetic material can cover one side of the film layer. And progressively filled in the cracks, wherein the film layer is a low melting point material layer. According to the purpose of the present invention, a packaging for packaging microwave food heating is proposed.

Page 10 522123 V. Description of the invention (8) The combination and manufacturing method thereof include: providing a film layer; and a process of rolling the film layer 'to form a plurality of gaps on the film layer. Wherein, before or after performing the rolling process step, a coating step is performed to cover a non-stick sealable material layer on the film layer, which acts as a gap filler to fill holes and cracks. The film layer has barrier properties without being deformed under pressure in a normal environment, but when the two sides of the crack of the film layer are deformed in a temperature and pressure difference environment, it becomes a through-hole breathable structure. Here, the material selection of the sealing material layer may be: (1) oleaginous materials, saturated, unsaturated, and hydrogenated grease; (2) wetting agent For example, wetting surfactants (surfactants); (3) Wax (wax), the wax type can be natural wax (natural wax) or synthetic wax (man-made or synthetic wax), such as natural wax Paim or carnauba wax, paraffin wax, microcrystal 1 ine wax, beeswax, rice bran wax, and other unlisted natural waxes, as well as synthetic waxes For example, polyethylene (PE) synthetic wax, polypropylene (PP) wax, polyethylene ο X ide (PE 0) emblem, and other unlisted petroleum products, mineral oil products, Synthesis of oxides of polyolefins (ρ ο 1 y ο 1 efi η), fakes and other materials; (4) fatty acids and its derivatives; (5) starch and its starchy derivatives (Starch and amyloid materials or their derivatives); (6) gum

522123 V. Description of invention (9) Second? . Two outsiders, the steps of the present invention further include performing-heat treatment to fill the sealing material layer-microwave food special packaging = breathable material for seed packaging cracking, this inconvenience restrictions · bismuth ^ material 'has been overcome The existing environmentally friendly materials used in microwave packaging materials are designed to be very flexible, 7 in order to completely make carbon without pollution. After J burns, only a large amount of water and dioxide are generated to avoid this special "material 2 foreign material pollution, except Can be exposed to pollution at the same time: ^ ^ In the microwave heating or cooking invention, β is free from gas explosion caused by heating and pressurization, this area = there is a very wide range of temperature to make an optimization Material and specification design. For the purpose of ^ χ, a breathable packaging bag is proposed, which includes the following structures: a film layer material is folded in half from the middle area and the inner side is overlapped with each other; A plurality of cracks, the folded overlapping film layer has an open end and the rest of the sealed seaied edges, which can include a layer of synthetic material On the surface of the film layer, it acts as a joint filler for the cracks on the film layer to fill the cracks, so that the film layer has barrier properties under normal pressure without deformation. As for the opening area, if necessary The structure with sealing function can use a similar sealed packaging bag (ziploc storage bag). Both sides of a mouth are borrowed from the grooves and protrusions of the zipper strip zipper located on the inside surface of the opening area of the film layer (gr 0 0 veandrib) linked to the inter locking) structure to open and close the open area and seal the opening

Page 12 522123 V. Description of the Invention (ο) The mouth-end method can also be heated and pressed. This product is cold. East-packaged food is heated in a microwave oven or in between shots. At the direct temperature of food that has been over-frozen and packaged, the vapor pressure associated with heat in the packaging bag is also low. Vibration and friction effects are often used by users of packaging materials (Polyethylene electric constant values are about 2. More than that in the microwave energy conversion system, the temperature rise is mainly in the cooking; the steaming associated with the heating and subsequent heating also increases, due to the bag The crack on the film layer of the bag increases toward the gap. As for the above, the position of the film cloth and the thickness of the film layer can be used to determine the final heat of the food. Adhesive tape, ultrasonic compression or air-permeable packaging bags can be used directly. When packing cold food, it is not necessary to open the open end to use it directly. ^ High temperature steam cooking, boiling and infrared photo & medium 'For example, in the microwave oven heating process, it is heated by the cold father. The low environmental shirt is also low, and the moisture content inside the food is increased. At this time, the temperature and pressure generated in the bag are still sealed. There is no clear gas through hole. At this time, the microwave energy is converted into heat energy by the ingredients in the food and will be confined to the bag. Because it is made of polyethylene, polypropylene, or polyethylene terephthalate (PET), etc. Dielectric 5 'The relative dielectric constant value of water is lower than 8 〇 It is changed to heat energy process, food has the highest ratio. The food itself, which means that the packaged food can be fully continued. The internal water pressure is gradually increasing, the pressure difference between the inside and outside of the packaging bag expands, and the internal pressure of the bag film is squeezed outwards, which causes the deformation of the extension to increase. The cracks are opened or the packaged food is cooked to what extent. The number of cracks on the layer, the shape, the distribution density, the distribution, the film material and the sealing crack material and other factors depend on the maturity or maturity. Here, when the heated food packaging bag is at a high level

522123 V. Description of the invention (π) The relative vapor pressure is also high under the temperature environment, which will promote the caulk material to gradually soften or become liquid or become thin or cracked due to heat, and the film will be extruded and extended by high temperature and high pressure. The deformation makes the crack opening space larger, and at this time, the crack also becomes a safe pressure-relief adjusting through hole with small resistance, which can avoid the hot air and high-pressure steam that slowly accumulate in the bag due to the heating process ( hot air and steam buildup) caused by instant explosion: In addition, the high-temperature air-permeable packaging bag for food can be stored and frozen directly after cooking for future use, as long as it is placed in a heating device Inside, such as a microwave oven, it can be directly heated. After heating for a short time, the packaging bag film can be peeled and the food can be used directly. According to the purpose of the present invention, another process for producing a breathable packaging bag is provided, which includes: a first film layer and a second film layer directly overlapping each other, wherein at least the first film layer has a product produced by a rolling process. A plurality of cracks, the first film layer and the second film layer are overlapped with each other and have an open end (〇pen end) and the remaining edges sealed (and the rest 〇f sealed edges) For the other side methods, heat pressing (heat: = 1 ing), ultrasonic pressing, or bonding with adhesive tape can be used. Among them, heat sealing is the most convenient. Furthermore, the air-permeable packaging bag to which the present invention is applied may also include two layers of synthetic material on the surface of the film layer. For the cracks on the film layer, a sealant is used to fill the cracks, so that the film The layer has barrier properties under normal environment without pressure deformation. In addition, the opening area also includes a similar sealed packaging bag (zip 1 〇cst 〇rage bag) which can be easily opened and closed. A sliding zipPer or any zipl0ck groove on the inner side of the opening area of the film layer

522123 Five convex and interlocking interlocking structures are used to open and close the open area. In addition, the open end can be sealed by using adhesive tape, ultrasonic pressure fusion, or heat compression. The types and combination of materials used in the microwave food packaging bag used in the present invention can be manufactured and designed according to the required specifications. The manufacturing method of the packaging bag material is described as follows: 77 1. A single material and a single film substrate, a. Stretcher (tenter), after extruding the molten polymer plastic material from the strip-shaped extruder (s 1 ot), clamp and fix it with two ends of the clamp and move in the vertical mechanical stretching direction (TD) Extend, and then perform another stretching action along the machine direction (MD) of the parallel film. The resulting film is a biaxially stretched film. Biaxially oriented polypropylene (Biaxially oriented polypropylene) currently used in the market, B0PP)), polyethyiene terephthalate (PET), polyethylene glycol pairs? Extension film such as dioyethyiene naphthalate (PEN). b · Blown film machine, extruding the melted polymer plastic raw material through the die nozzle, the cylindrical film is extended under high temperature and high pressure gas to make the blown film follow the manufacturing process. Extending in two directions in the axial direction and the stretching direction is a type of biaxially stretched film. It is rolled up in the later stage after cooling and overlapping the material along the half-circle length. Dividing at the folding corner, you can get a film width that is the total length of the blown film. If you divide the two folding corners, you can get two single-layer plastic films with half-circle length. This process uses a lower melting point. Comparison of polyethylene and polypropylene

Equivalent layer: owing to concentricity ^ κ ^ τ, the multilayer film formed into a column extends in a high-temperature environment and a high-pressure gas branch, so that the blown film is extended in the axial direction and in the stretched second-degree space during the manufacturing process. This type of film is mostly used in food packaging. Φ The film of Bushishi is a multi-layer composite film formed at one time, such as multi-layer co-extrusion propylene film (CPP) and EVA / PE co-extrusion film. ^ • Laminating film / CUrtain Coating machine), the molten polymer plastic material is squeezed out through the die T-die to form a uniform molten plastic film on the carrier film, which is the most common Examples are paper, plastic film substrates such as PETS coating film pE, eva or wax materials on it. In the manufacturing process, the melted plastic material is directly adhered to the substrate paper, PET or PP film when melted at high temperature. 'In order to improve the adhesion between the substrate paper, PET or PE, the substrate paper, PET or PP can be treated by corona discharge or surface modifier reagent on the coating. To change the surface energy to improve its adhesion to the coating material. c. Laminated composite film, using gravure wheels, wire rods, doctor blades, or five-wheel coating processes, on a single-layer film or a multi-layer a film on one side of another film layer intended to be laminated The above method is to first apply an adhesive layer, and then apply pressure to another film layer to obtain another new multilayer composite film.

Page 23 522123 V. Description of the invention (21) Solution type, dispersion solution type, or mi cron i zed powder type and other types are recoated. It is worth noting that if the present invention is applied to food packaging materials, the sealing material used can be edible waxes or oils approved by the US Food and Drug Administration (FDA), such as the aforementioned types Sealable material. This sealable material has many characteristics including that it does not affect the gloss, printability and heat sealability of the film, and does not have a special odor during use, and is imperceptible. In addition, the rolled breathable film structure with a soil coating has better water repellency and heat sealability than the rolled breathable film structure without a coating. Among them, an emulsion wax and an FDA approved The edible and antibacterial sealing material can be widely used in food packaging. As for Paraffi η 躐, it is mainly used for its excellent water repellency (waterrepe 1 1 abi 1 ity), but it can improve the water vapor permeability rate, so when it is used in sealed food packaging bags, it can avoid excessive water. The vapour pressure broke the packaging bag. Although the 'crack region 15' will return to a pseudo planar shape with cracks, this layer of sealing material layer 6 will also partially penetrate into the cracks. The preferred melting point range of this sealing material is between 40 ° C and 110 ° C, but other temperature ranges are also suitable for the present invention. In addition, if the present invention is applied to food packaging materials, in order to maintain the freshness of the sealed food, it is also possible to mix the sealing material or the film layer with a material that removes oxygen components in the packaging bag Materials, such as some oxidizable metal components, such as iron, Shao, Ci, nickel, copper, manganese, etc.

Save it, and it will not have its function of removing milk gas until it is sealed, or it can keep part of its work of removing oxygen b. It is worth noting that in this heat-sealing step or subsequent heat-treatment step, a part of the sealing material layer 6 further penetrates into the cracks', so that the present invention obtains a further sealing effect. Therefore, in the processing of the film of the present invention, a heat treatment step can be selectively used: for example, microwave or infrared heating, so that the sealing material coated on the surface of the film can be reliably filled into the cracks on the surface of the film. In this way, the above-mentioned packaging materials have freshness, moisture retention, moisture resistance, discoloration prevention and odor prevention for the sealed food under low temperature and ordinary temperature environment. However, as the heating process continues, the food is heated in the microwave oven due to microwave energy. The conversion into heat energy causes food and the bag to slowly accumulate hot air and high temperature and high pressure steam (hot steam buildup). At this time, the packaging bag film is extruded and deformed by high temperature and high pressure, which causes the opening space of the slit to become larger and cracks It becomes a low-resistance pressure relief through-hole. At this time, if the sealing material is coated with a sealing material, it will become soft and thin due to the high-temperature and high-pressure environment.
