542812 五、發明說明(1) 本發明是有關於一種食品包裝組合用透氣性材料,且特別 是有關於一種具有與溫度相關之透氣選擇性材料及其製造 應用方法。 自古以來,食品之烹煮大多以火烤、高溫水煮或蒸炊方式 來進行熟食,而使用高能源效率之微波進行加熱或烹煮食 品至今已有超過5 0年之歷史。其中,工業化程度較高之國 家,在方便與速捷的訴求下,於一般家庭、學校、餐廳或 其他公共場所使用微波爐烹煮與加熱食品比率也較高。 微波電磁波(M i c r 〇 w a v e )之加熱食品原理,乃利用被加熱 材料中各成分極性分子本身具有之偶極矩’於微波電磁波 向量場内為了要配向於磁電場,因而發生激烈的振動或迴 轉運動。材料藉本身之阻尼(D a m p i n g )作用將偶極矩之振 動能量藉摩擦消散轉化成熱能(h e a t)而使整體系統内内能 能量累積與增溫,致使含材料之系統溫度上升,一般而 言,偶極矩強度越高或材料成分之相對介電常數 (dielectric constant)值越高者,其轉化電磁波能量為 熱能的比率越高,意即材料昇溫效果越佳與受熱的速度也 越快。純水的相對介電常數值於室溫下接近8 0,而聚乙烯 的介電常數值於室溫下為2. 5 1,所以含水之食品包覆於聚 乙烯之包裝材料中同時在微波電磁場下受熱,理論上大部 分之微波電磁能由水成份轉化為熱能,換言之,受熱系統 内之加熱升溫以食品為主,包裝材料反而因熱轉換比例低 其本身材質升溫較少。並且,微波具有一般電磁波的穿透542812 V. Description of the invention (1) The present invention relates to a breathable material for food packaging combination, and in particular to a temperature-dependent breathable selective material and a method for manufacturing and applying the same. Since ancient times, most foods have been cooked by fire-baking, high-temperature boiling or steaming, and energy-efficient microwaves have been used to heat or cook foods for more than 50 years. Among them, countries with a high degree of industrialization have higher ratios of cooking and heating foods using microwave ovens in ordinary homes, schools, restaurants or other public places due to convenience and speed. The principle of microwave food (Micr 0wave) for heating food is to use the dipole moment of the polar molecules of each component in the material being heated in order to align with the magnetic field in the vector field of the microwave electromagnetic wave, so intense vibration or rotary motion occurs. . The material uses its own damping action to convert the vibrational energy of the dipole moment into heat through friction dissipation, which causes the internal energy energy in the overall system to accumulate and increase the temperature, which causes the temperature of the system containing the material to rise. Generally speaking, The higher the dipole moment strength or the higher the relative dielectric constant of the material composition, the higher the ratio of converting electromagnetic wave energy to thermal energy, which means that the better the material's heating effect and the faster the rate of heat. The relative permittivity of pure water is close to 80 at room temperature, and the permittivity of polyethylene is 2. 5 1 at room temperature, so water-containing food is coated in polyethylene packaging material while being microwaved. When heated under an electromagnetic field, theoretically most of the microwave electromagnetic energy is converted from water to heat energy. In other words, the heating temperature in the heating system is mainly food, but the packaging material has less heating due to the low heat conversion ratio. In addition, microwaves have the penetration of general electromagnetic waves

Description of the invention (5) It is not delicious. In order to prevent food packaging materials from exploding in microwave heating applications, research and development work has continued in the early days. 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 material manufacturing methods, such as U.S. Patent Nos. 3, 3 7 8, 5 07, 3,310, 505, 3, 607, 793, 3,812, 224, 4, 247,498, 4,466, 9 3 1 and The technology disclosed in 5, 9 2 8, 5 8 2 includes the use of incompatible materials to form a film, and then using a stroke method to dissolve one of the components to form a hole-like structure. Most of these breathable materials It is used for filtration and separation, such as the separator in the battery that allows the electrolyte to flow and the isolation dialysis membrane (d 1 a 1 y 11 cf 1 1 m) for pure water purification or seawater desalination. The mechanical strength of the material layer is inversely related to the porosity. This material is used in microwave food packaging applications, and the private explosion phenomenon still occurs when U-wave heating occurs, and the residual unextracted material is too much, which is easy to cause during the microwave heating process. It has a relatively high dielectric constant value and forms a heat spot during the conversion of microwave energy into heat, which causes the packaging material to be partially melted and penetrated by heat. As a result, a large amount of volatile components in the food is lost. This material is not suitable for microwave food packaging, and has extremely high manufacturing costs and complicated extraction solvent recovery procedures. Another type of breathable material, such as the technology disclosed in U.S. Patent No. 5, 8 6 5, 9 26, is the use of non-woven or fiber cloth with breathable properties. However, these methods will make the air-permeable film have giant holes (m a c r 0 p 〇 r 〇 u s) characteristics, most of which

At present, this type of U-port is not used consistently, and there is still an explosion phenomenon that occurs in the microwave heating process. Similarly, most of the inorganic salt additives added in it It belongs to a material with a low ratio and a relatively high dielectric constant, which is more likely to form a local impact in a heated environment, and the heat spot 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, processing temperature, film thickness, and raw material formulations, etc., which will lead to inconsistent pores / same size, and the use of additives will affect the subsequent environment. Different impacts', for example, may cause environmental issues. In addition, it is limited by the choice of the film material, and the film formation is not transparent after the film formation due to the multiple phases of the additives. Furthermore, a stretching step is required. In addition, when this breathable material is applied to food packaging, there is a concern that the additive will contaminate the packaged food, causing unpleasant odors.

Description of the invention (23) Other temperature ranges are also applicable to 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, inscriptions, dictionaries, copper, copper, special compounds or chemical compounds such as sodium bisulfate, sulfuric acid, sulfuric acid Iron (ferrous sulfate), zinc sulfate (zinc sulfate) and other materials that easily react with oxygen, or the above-mentioned oxygen scavenger materials are packaged in sachet and then sealed together In the packaging film of the invention. In practice, because these oxygen-removing materials are doped in low-melting-point materials or films, the inventory period before the subsequent heat-sealing step can be used to remove oxygen. It is stored until it is sealed, and it does not have its function of removing milk gas or it can retain part of its function of removing oxygen. It is worth noting that in this heat sealing step or the subsequent heat treatment step, a part of the sealing material layer 16 further penetrates into the crack, so that the present invention obtains a further sealing effect. Therefore, during the processing of the film of the present invention, a heat treatment step such as microwave or infrared heating can be selectively used, so that the sealing material coated on the film surface can be reliably filled into the cracks on the film surface. In this way, the above-mentioned packaging materials have freshness, moisturization, 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 without cooking, due to microwave energy conversion. Make food for heat

Another object of the present invention is to use materials with further oxygen components on the material. The present invention is not limited to the use of the packaging bag of the present invention and the simultaneous use of microwave ovens, which must be cost-effective without coating and sealing. The structure of the sentence body is similar to the water content contained in a sub-food. At the same time, due to the concentration of the amount, the low-temperature packaging bag used in foods can be thawed and used directly in food applications. This is necessary for every second. For food applications, it achieves the purpose of coating a food layer. For food cooking, air-tight vapor pressure, microwave cooking of wine, ice in this package> Eastern food is competing with hot air and high-temperature and high-pressure steam. The external compression space becomes larger, and the crack becomes a smaller resistance. At this time, if the sealing material is coated with a sealing material, it will also become thinner due to softness or a smaller resistance.
