Description

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

Ren, He-all corners and all of them are heating the object, transforming temperature, eight +: mping) / Xiao San into the principle of thermal energy and The effect of "turning: = higher in the system to increase the temperature effect is better. Article two: heating, drying, cooking, baking, sterilization and other processing should be Hertz (Mil heat microwave frequency is 91 5 million Hertz ( MHz) and 245 0 million 4 ill, magnetic waves. In addition, the relative permittivity value of food materials: 2 temperature and microwave frequency during heating are related. Process: Ϊ bleed and harden food using microwave for heating The two big questions about cooking:;:,;: This is because the food has high dielectric constants :: ,, and components (such as water). High dielectric constant components can convert electromagnetic wave energy into The characteristics of heat energy and high volatility and high vapour pressure make the material knife easy to fork heat and volatilize quickly, which makes the food dry and hard, and loses its deliciousness. In the microwave heating application market, the more common microwave ovens use packaging materials with fresh-keeping film (Wrap f ilm), microwave container Such as dishes, bowls, etc. The packaging material used is selected from polyethylene (PE), polypropylene (pp), nylon (nyoni), polystyrene (PS), polycarbonate (pc) ), Polyvinyl chloride (PVC), polyvinylidene chloride (PDVC), polyvinyl pentamidine (pmp), ethylene-vinyl acetate (EVA), polyurethane (PU), or SurlynTM (Brand name of Dupont ionomer), polyethylene terephtha1ate (PET), polyvinyl alcohol

In practice, in order to facilitate the manufacture of such packaging materials, packaging companies often add plasticizers (plastieizer additives) in the packaging material manufacturing process to improve their processing convenience. And this—food packaging materials ^ The additives used in food packaging, storage, transportation, or microwave processing: in the process of cooking, because of direct contact with food, which may cause food contamination and harm health. == This, the US Food and Health Administration (fda) and domestic health = quasi 2 food packaging materials requirements and restrictions: In addition to the requirement that food must not be contaminated with packaging materials, it also increased = material: high temperature The use of temperature resistance characteristics and low and high temperature cracking specifications.

For example, the food contained in t at time is easy to smoke: 2 The food is in the open air: and: 1 is lost, causing the food to dry and hard. 2 points Due to the heat, the food is lost in the heating process.

Make food

542812 V. 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

542812 V. Description of the invention (6) It is applied to paper diapers and thirsty paper towels. It is suitable for the manufacture of microwave food packaging. S = customary materials, such as US patent number 3, 679,540 ^ 4,187390 ^ 4 350 a λ a η, bb 4,466, 93, 4, 777, 073 and 5,340, 646, the technology disclosed in the case, by the use of inorganic material powder, such as calcium metabolite (C = C03), titanium oxide (Ti〇2) or aluminum oxide (Ai203), uniformly blended into the organic surface molecular material φ; take 7 Qi Ke inch ten such as + ethylene 'and then extrude into a film.

Although this manufacturing method can produce micro holes

Uicyoporc ^ s), but the manufacturing cost is too high and the difficulty is high. 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.

This kind of breathable membrane contains oil or 2 block oil and alcohol, so it will be adsorbed by capillary, and cannot: alcohol content, its further effect is when applied: 70% impregnated with t ΐ inside contains deoxidation In the case of a pouch, the combination of ^ food bag ^ and ㈣ is not contaminated and cannot maintain the function of maintaining the oxygen agent ingredients during heating or cooking. = When heating directly, microwave heating often borrows food; =, when using ingredients such as water, it can effectively borrow microwaves to co-vibrate with the effect library: =: damping property of the electric cymbal can lift the micro 52 2 itself to the inside Steaming: The body ... The microwave heating process caused the water temperature to rise. When this breathable film was used by Yuntian because it contains low specific heat characteristics, it is easy to: 1: package food Risi, the material is heated in the microwave spot) However, when the melt is melted and the heat is generated during the day and day, the hot spot (heating is more severe, and // =, which causes the gas and liquid inside the package to be easily peeled off.) During the process of sterilization and disinfection of articles and high temperature, The pirate-like, two: If the packaging container is covered-the traditional air-impermeable packaging film forms a closed system.

V. Description of the invention (12) Fresh, water repel lent, barrier and gas barrier properties of the coating layer of I material need to be considered.

According to the purpose of the present invention, a breathable material for food packaging containers is proposed. This microwave food special packaging material has overcome the limitations and limitations of existing microwave packaging materials. The material formula is very flexible in design and can be completely used. Recyclable materials. After the material is completely burned, it only generates water and carbon dioxide. There is no pollution problem and the food is not contaminated by foreign objects. In addition to avoiding this special packaging material in the microwave heating or cooking process, it can also be contaminated with food. Avoid gas explosion caused by temperature increase and pressure increase. The manufacturing method and packaging material of the present invention have a very wide temperature range. According to food characteristics and customer requirements, the temperature resistance requirements, size and shape of packaging products can be regulated袼 Do an optimized material and specification design. In addition, according to the purpose of the present invention, a breathable packaging bag is provided, which includes the following structure: a film material is folded in half from the middle area and the inner side is overlapped with each other. The utility model has a plurality of cracks generated by the pressing process, and the folded heavy film layer has Has an open end (0pen end) and the rest of the seal

The rest of sealed edges. It can include a layer of synthetic material located on the surface of the film layer.

(i n t e r 1 〇 c k i n g) structure, in order to open and close the opening area, in addition to sealing eight sections, the mouth end method can also use direct tape bonding, ultrasonic compression ^ = heating compression method. The air-permeable packaging bag can be directly used for packing cold food mouthfuls. When taking cold / east packaged food, it can be directly heated in a microwave without opening the open end, or indirectly using high-temperature steam cooking, boiling, and infrared heating. In the heating process, such as in the microwave oven, the food that is frozen and packaged is directly heated. The initially heated food is at a lower temperature, the temperature in the packaging bag is lower, and the moisture contained in the food is ^ $ The steam pressure associated with the heat is also low. At this time, the temperature and pressure generated in the bag are still low. 'The film layer of the packaging bag and the cracks on it are still bulging deformations and vent holes through which the sealing structure is not obvious. Microwave energy is converted into heat energy by the vibration and friction effects of the eight ingredients in the food and will be confined in the bag. The common users of packaging materials are polyethylene, polypropylene, or polyethylene terephthalate (PET). The relative permittivity values of other materials are about 2.5, which is much lower than the relative permittivity value of water, which is 80%. In the process of converting microwave energy to thermal energy, the ratio of food is the most. high,

= The increase in temperature is mainly in the food itself, which means that the packaged food can be fully cooked by the lamb. As the heating continues, the temperature in the bag gradually rises, and the vapor pressure associated with the water trauma fever in the food in the bag gradually increases. The pressure difference between the inside and outside also increases. 'As the bag swells, the internal pressure of the bag film is squeezed outwards, and the deformation of the cracks on the bag film layer extending outwards increases, and the cracks open or the crack gaps increase. The degree of cooking can be determined by controlling the number of cracks, shape, distribution density, distribution location, film thickness, film material and sealing crack material in the film layer.

542812 V. Description of the invention (14) The final heat or maturity of the food is determined. Here, when the heated food packaging bag has a relatively high vapor pressure in a high temperature environment, this will cause the caulk material to gradually soften due to heat due to heat or It becomes liquid or the thickness becomes thin or cracks. In addition, the film is deformed by high temperature and high pressure to extend and deform, so that the crack opening space becomes larger. At this time, the crack = place also becomes a safe pressure-relief adjusting through hole with less resistance. The instant explosive dangerous phenomenon caused by the hot air and steam buildup that slowly accumulate in the bag due to the heating process. In addition, the high-temperature air-permeable packaging bag can be used to store the frozen food directly after cooking for future use. When it is eaten, it can be placed in a heating device, such as a microwave oven, and directly heated. Use the food directly after tearing the packaging bag film. '、 According to the purpose of the present invention, another process for producing a breathable bag is provided, which includes: a first film layer and a second film layer directly stacked on each other, and at least the film layer 1 has 11 pressing processes. A plurality of t-slits are produced. The f-th layer and the second film layer are overlapped with each other and have an open end and the rest sealed edges, which are sealed. The other side methods can use pressure-sealing, ultrasound compression, and use Zheng Zheng to deal with people. The entrance is glued with standing glue π, in which two private seals are sealed by hot pressing. In addition, the air-permeable bag using the present invention may also include a -1L material layer on the surface of the film layer. For the crack system on the film layer = true seam agent is used to fill the cracks, the film layer is used in + Under normal environment, the film layer has barrier ... The outer opening area also includes f-like a sealed packaging bag (ziPl0C storage bag) that can be easily opened and closed.
