TW482722B - Method for manufacturing an air permeable composite film - Google Patents

Abstract

A method for manufacturing a novel air permeable composite film is disclosed. The air permeable composite film has a polymer layer with a top face and a bottom face and a sealing layer covering the top face. The polymer layer is first perforated by virtue of an impression process to from a plurality of tiny gaps in it for air permeation. Then the sealing layer is coated on the top face of the polymer layer to fill the gaps. The differential pressure between the top face and bottom face of the polymer layer enlarges the gaps and makes the gaps become air permeable.

Description

482722 V. Description of the invention (1) The present invention relates to a breathable material, and more particularly to a material substance having a breathable property and its application and manufacturing method. Many different kinds of breathable materials are currently being developed. One of these conventional breathable material manufacturing methods, such as US Patent No. 3,3 78,5 0 7 ^ 3,3 1 0,5 0 5 ^ 3,6 0 7,7 9 3 ^ 3,8 1 2 , 2 24 ^ 4 ^ 24 7 ^ 4 9 8, 4, 4 6 6, 9 3 1 and 5, 9 2 8, 5 8 2 The techniques disclosed in the case, including the use of incompatible materials to form a film, and then An extraction method is used to dissolve out one of the components to form a pore-like structure. This kind of air-permeable material is mostly used for filtration and separation. Another type of breathable material, such as the technology disclosed in U.S. Patent No. 5,8,65,9,26, uses a non-woven fabric or a fiber cloth having breathability. However, all of these methods can make the air-permeable film have the characteristics of macropores (maCr0P0r0us). 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, 3 4 0, 6 4 6 The disclosed technology involves uniformly blending inorganic material powders, such as calcium carbonate (CaC03), titanium oxide (Ti〇2), or aluminum oxide (A 1 203), into an organic polymer material, such as polyethylene, and then extruding Out of film. The film forming method includes a method of using a concentric circular die (d 丨 e) extrusion injection method to obtain a cylindrical pull bag, an extension tenter (tenter) stretching, or an extrusion injection method. 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,

UicroPorous), but the manufacturing cost is too high and the difficulty is high. It is worth noting that this manufacturing method will lead to inconsistent quality control of breathable films, such as elongation, processing temperature, film thickness, and raw material formulation.

482722 V. Description of the invention (2) The size of the holes will be inconsistent, and the use of additives will have different effects on the subsequent environment, for example, it may cause environmental problems. In addition, it is limited by the selectivity of the film material, and the film is often not transparent after being formed due to the multi-phase combination of additives (mul tipU phases). Furthermore, a stretching step is required. In addition, when this kind of breathable material is applied to food packaging, there is a concern that the additives contaminate the packaging, 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 be impregnated with oil and alcohol due to capillary adsorption. 忐 * ^ ^ ^ ^ Its further effect is that when the air-permeable film is applied to food packaging and contains a deoxidizer pouch inside, it will cause the deoxidizer ingredients to be scooped by oil and alcohol | fresh function. It is not possible to maintain food. When this breathable film is used to heat the breathable film directly in the microwave oven;: Day: If the body has low specific heat characteristics during the heating process, it is 20% of the packaging. Because of its inherent heat spot (heatlng spot), and melting point = time, the gas-liquid inside leaked by the concentrated heat will produce more severe sweat and larger holes, resulting in the sterilization process of the packaging, this breathable film; and The main purpose of the present invention is to peel off during the filling of articles and high-temperature sterilization. The manufacturing method and application are used to change the cover Z f = a kind of breathable material and its point I.

In addition to itb, the step of the present invention further includes performing a heat treatment step so that the sealing material layer is filled into the cracks. According to the purpose of the present invention, a breathable packaging bag is provided, which includes the following structure: a film layer material is folded in half from the middle area and the inner side is overlapped with each other, and the film layer has a plurality of cracks generated by a rolling process. The folded overlapping film layer has an open end and the rest of sealed edges. It can include a layer of synthetic material located on the surface of the film layer. For cracks on the film layer, it acts as a joint sealant to fill the cracks, so that the film layer does not deform under normal conditions. The layer has barrier properties.

Pressing method. The breathable packaging bag can be directly used for packaging frozen food. When the frozen packaged food is taken out, it can be heated directly in a microwave oven or indirectly by high-temperature steam cooking, boiling, and infrared irradiation. During the heating process, For example, during the microwave heating process, the food packaged by the cold bed is directly heated. The initial temperature of the heated food is at a lower ambient temperature, and the temperature in the packaging bag is also lower. The moisture contained in the food is also higher than the vapor pressure associated with heating. Low, at this time the temperature and pressure generated in the bag are still low, and the film layer of the packaging bag and the cracks on it are still in a sealed structure.

482722 V. Description of the invention (5)

The prominent bulge deformation and the ventilating through-hole, at this time the microwave energy is converted into heat by the vibration and friction effects of the constituent molecules in the food, which will be confined to the bag, and the packaged food can be fully cooked. As the heating continues, the bag The internal temperature gradually rises, and the vapor pressure associated with the moisture in the food in the bag gradually increases, and the pressure difference between the inside and outside of the packaging bag also increases. As the bag expands, the internal pressure of the bag film is squeezed outwards, which causes cracks in the bag film layer. As the amount of deformation extending outward increases, the cracks open or the gaps in cracks increase. As for the degree to which the packaged food is cooked, its design can be controlled by controlling the number, shape, distribution density, distribution location, The thickness of the film layer, the material of the film layer, and the material used to seal the cracks determine the final maturity of the food. Here, the relative vapor pressure of the heated food packaging bag is also high in a high temperature environment, which will cause the joint filling material to be solid. Due to heat, it gradually softens or becomes liquid or the thickness becomes thin or cracks. In addition, the film is deformed by high temperature and high pressure, which causes the crack opening space to become larger. It also becomes a safe pressure-relief adjusting through hole with small resistance, which can avoid the instant explosion danger caused by the hot air and high-pressure steam (h 〇tairandsteambui 1 dup) slowly accumulated in the bag due to the heating process. . In addition, the high-temperature air-permeable packaging bag can be directly sealed and frozen after cooking. As long as the food is placed in a heating device, such as a microwave oven, it can be directly heated. After heating for a short time, the packaging bag film can be opened and 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 (open

Wherein, the air-permeable packaging bag to which the present invention is applied may also include an adhesive material layer on the surface of the film layer. For cracks on the film layer, it acts as a joint sealant to fill the cracks, so that the film layer is The film layer has barrier properties under normal pressure without deformation. In addition, the opening area also includes a similarly recloseable zipper storage bag that can be easily opened and closed. Both sides of an opening are located at the opening of the film layer. The sliding structure on the inner side of the area is connected with the structure of the groove and the groove (gr ο 〇veandrib) (inter 1 cking) to open and close the opening area.

However, because it is translucent or even visible, can you see the food in the packaging? The packaging material is increasingly using transparent materials as the material of the film. B The present invention can also follow the trend as the first As shown in Fig. 1C, the structure of the structure of 100 is composed of the first layer of material i 0 and the structure k is expected from the three layers of material 30. The first layer of material]. For example, and the third The layer material 20 is, for example, a low-melting point or a heat-sealable material with a low melting point. The second is, for example, a low-melting point heat-sealable material. The third layer material is 3 0. Please refer to Figures 2A, 2B, and 2C, Figure 28, and Section 2C after the rolling step, and Figure 2C of Figure 2 show the process of the present invention on one side 12 and on the second side 14 in the direction of ^ ° pressure. Is the first process from film 10 including comprehensive rolling or selecting structure 10 for rolling steps (rolling equipment required for rolling) In order to adopt the continuous green rolling method, the rolling method is adopted, especially for the TM wheel set or the counter-roller set in the batch-type flattening or the flat-plate platform under the automation requirements. It is more economical, and its several spiky structures (not shown in the figure), the surface of a round or a platform is made by a double method: (1) the electroplating method can be used to multiply this spiky structure by the following method Similar particles of powder are uniformly plated on I-hedron diamond particle powder or high hardness will harden the plutonium molecule, metal or Taomante; (2), the laser cutting method has a uniform multiple spiky structure chain hair Engraving from face to face "such as laser cut pottery

482722 V. Description of the invention (ίο) Yao anilox rol 1 wheel; (3) Using mechanical processing (tooling) processing method, a metal surface of an appropriate hardness is formed into a desired surface uniform sharp structure 'and then applied Surface hardening treatment (hardening treatment) to form the final rolling surface required; (4) a metal surface is chemically electrolytically carved into a uniform sharp convex structure, and then surface hardening treatment to form a hard rolling surface. In addition, the material of the counter pressure wheel or the counter pressure surface corresponding to the rolling wheel may be a metal, plastic steel or ceramic with a suitable hardness. As mentioned above, regardless of the use of electroplated diamond wheels, mechanical processing wheels or rolling wheels for surface laser engraving, the rolling process makes the structure 1000 have a permanent failure structure and cracks on the structure. The area 15 here, the structure area of the crack area 15 may be various shapes of holes or cracks of various shapes, and the upper part has a breathable structure 102. Here, the stabbed film can be provided with a structural design according to actual needs. Among them, the best can be obtained by selecting suitable rolling mechanisms and conditions. 15 It can also have an inhomogeneous distribution and locality due to actual needs. Regional distribution, distribution, as to the actual use timing and materials, processing conditions, and required because the present invention is applied to this breathable solid fragile material, and most of them are lumpy, so the film has the shape memory effect of short-term rolling The material structure of the material is damaged and deformed for a long time. The required sealing and ventilating functional characteristics are the same as when the material is matched with different rolling wheels. The distribution design of the crack area of the present invention is the same, for example, it can be fully regular. The distribution or irregular sealing application mechanism depends on the material to be encapsulated and the sealant. The material used for the structural structure 1 0 2 is not elastic (viscoelasticity) material. The macroscopic structure after pressing will be largely restored due to the nature of the material, leaving only permanent cracks, such as after rolling.

482722 V. Description of the invention (11) The holes or cracks of various shapes generated, most of the original planar appearance will still return to a flat shape, but at this time it is a multi-phase structure that is a pseudo planar structure phases), which is the second permanent deformation crack-like structural phase in the continuous phase of the rolled film. However, when the present invention is used in the future, the pressure on both sides of the outer membrane [for example, the pressure of hot water vapor pressure in the seal, will be stretched and deformed around the seal structure to show the original slit-like structural change again. Big. The present invention utilizes this principle. In addition, the film achieves a good ventilation effect under a pressure difference environment. The protrusions on the segmented and rolling mechanism used by iil can be line ^ ® cone, pyramid, square cone, Xipinjiang, column or other types, so after rolling :: The shape of the breathable structure before the shape of the plane of the ten child plane will also be equal to the shape of the cone, the pyramid, the pyramid, and the square pyramid. The corresponding line segment: the shape of the crack or other types of cones and cross columns. ^ ^ ^^^^ (v.scoelast.cHyt ^, the macroscopic structure on the structure 100, the memory of most of the two bodies is restored, leaving only the crack material that permanently destroys the deformation and the macroscopic structure will be restored In the figure, only the cross-shaped crack material is used, and the figure of the warrior can be the shape of some areas of Figures 2A, 2B, and 2C. As an example, the schematic diagram of the crack on the air-permeable structure is shown. Showcase 482722 V. Description of the invention (12) Figure 4 shows the schematic diagram of a composite material layer 6 formed on the breathable structure. Please refer to Figure 4, and then you can selectively On the side 1 2 'coated a low melting point sealing material layer 1 6. Here only the first} The structure of a diagram illustrates the example of the present invention. The sealing material layer 16 can also be formed on the film shown in FIGS. 丨 B and 1C. The sealing material layer 16 is borrowed. The direct coating method is applied on the base film layer after being rolled or it is first coated on the base film 10 and then rolled together with the base film. Here, the sealing material layer 16 plays a role The sealant function is used to fill holes and cracks 'makes the film layer deformable under normal conditions without pressure deformation', but when there is a pressure difference between the two sides of the film crack deformation under pressure It becomes a breathable structure with through holes. The sealing material layer selection here can be: (1) grease and (or grease), saturated, unsaturated, and hydrogenated (hydrogenated) fats and oils; (2) wetting agents, such as surf actants; (3) wax, which can be natural wax or natural wax Man-made or synthetic wax, such as palm wax, paraffin wax, microcrystal 1 ine wax, beeswax, rice bran wax, and other unlisted natural waxes.For synthetic soil, for example, polywax Polyethylene (PE) synthetic soil, polypropylene oxide (PP0) wax, polyethylene oxide (PE0) wax, and other unlisted stones, manufactured products, mineral oil products, polyolefins Oxygen (P〇1 y 〇1 efi η), wax and other materials

482722 V. Description of the invention (13) Chemical compound soil, (4) fatty acids and their derivatives (f a 11 y a c d a n d its derivatives); (5) starch and starchy derivatives (starch and amyloid materials). In the case of the present invention, the manufacturing process of the air-permeable membrane of the present name further includes performing a heat treatment step so that the sealing material layer 16 is filled in the cracks. The sealing material layer 6 is recoated by formulating the sealing material into different emulsion solution type, dispersion solution type, or micronized powder type. Made of cloth. 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 wax layer coating has better water repellency and heat sealability than the rolled breathable film structure without a coating layer. Among them, it is more emulsified wax and has FDA approval. The edible and antibacterial sealing material can be widely used in food packaging. As for Paraffi η 蠛, it is mainly used for its excellent water repellability, but it can improve the water vapor permeability rate, so when it is applied to sealed food packaging bags, excessive water vapor pressure can be avoided Packing bag. Although the 'crack region 15' will return to a pseudo planar shape with cracks, it is said that this layer of sealing material layer 16 will also partially penetrate into the cracks. The preferred melting point range for this sealability material is between 40 ° C and 110 ° C, but

482722 V. Description of the invention (14) 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, rhenium, diction, chain, copper, and other materials or compounds (chemica 1 compound) such as sodium bisulfate, sulfuric acid ), Ferrous sulfate, zinc sulfate, and other materials that easily react with oxygen, or package the above materials with oxygen see venger in sachet Co-sealed in the packaging film of the present invention. In practical applications, because these oxygen-removing materials are doped in low-melting-point materials or films, the stock removal function before the subsequent heat sealing step can be preserved. Get up, do not begin to have its oxygen removal function or can retain part of the oxygen removal function until after sealing. It is worth noting that in this heat sealing step or subsequent heat treatment step, a part of the sealing material layer 6 will further penetrate into the cracks', so that the present invention can obtain 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 resistance 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 conversion. Make food for heat

Page 18 482722 V. Description of the invention (15) Hot air and high temperature and high pressure steam (h0t air and steam buildup) are slowly accumulated inside the bag. At this time, the packaging bag film is extruded and deformed by high temperature and pressure to cause cracks. The opening space becomes larger, and the crack becomes a safe bubble pressure adjusting through hole with less resistance. At this time, if the sealing material is coated with a sealing material, it will also become softer and thinner or become a resistance due to the temperature and pressure in the south. The small pressure relief regulator has a through hole and has functions such as relatively high vapor transmission rate. Another object of the present invention is to further apply to the packaging material of food articles (comestible articles). The sealing material layer 6 can be blended to remove oxygen components to achieve the functions of food preservation and deodorization. However, the present invention is not limited to the need to apply a sealing material, and the present invention can also be used to achieve the purpose of the invention in the case where the sealing material layer 16 is not applied and is directly blended into the substrate film layer. . The packaging bag of the present invention is used for packaging of food (comestible articles) and cooking with a microwave oven at the same time. For cooked food, the degree of cookedness is uniform throughout, and the food contains Moisture, wine's oiliness, delicious aroma, and other special ingredients. At the same time, because of the high heating efficiency of cooking in a microwave oven, the cooking time of food is greatly shortened and energy can be saved. In practical applications, this packaging is used. The frozen food in the bag does not need to be thawed first, and the frozen food can be directly heated in a microwave oven to be cooked and eaten directly. This has extremely convenient application characteristics for the modern society where every minute counts. In addition, in the manufacturing process of the present invention, the coating step of the low melting point sealing material layer 16 may be performed first, and then the air-permeable structure 1 2 rolling step may be performed.

Page 19 482722 V. Description of Invention (16). In addition, after the rolling step of the film 10 and the low-melting-point sealing material layer 16 is performed, a heat treatment process may be selectively performed so that the low-melting-point sealing material layer 16 further penetrates into the air-permeable structure 1 0 In the fissure region 15 of 2, a further seal-enhancing effect is obtained. As for an application example of the present invention, please refer to FIG. 5. However, it is worth noting that the application examples listed here are not intended to limit the present invention. Any person skilled in the art will not depart from the spirit and scope of the present invention. Various modifications and retouchings are still within the scope of the present invention. The present invention can be applied to a breathable packaging bag. First, a breathable structure 102 material (as shown in Figures 2 A, 2 B, and 2 C) is provided, for example, including a film layer 10, and the surface of the film layer A low-melting-point sealing material layer 16 may be applied. As described above, in the present invention, the surface of the film layer may not be coated with the low-melting-point sealing material layer 16 in application. Then, for example, the air-permeable structure 102 can be folded in half from the middle region and the inner surface sides are overlapped with each other, so that the low-melting-point sealing material layer 16 is located on the inner side. That is, the low-melting-point sealing material layer 16 is in a state of being adjacent to each other in the folded structure. Next, the two sides of the air-permeable structure 102 are superimposed and sealed together, while leaving an opening 17 for placing an article (such as food). As shown in FIG. 6, it is worth noting that the present invention is not limited to the above-mentioned applications. The air-permeable packaging bag applied by the present invention may also be one in which two air-permeable structures 104 and air-permeable structures 106 are mutually connected. Fold them together to seal the triple edges 32. The method of sealing the three edges can be closed zipper, sliding zipper, or directly using adhesive tape and ultrasonic compression. Or use plus

Page 20 482722 V. Description of the invention (17) The method of heat-pressing, and keep one unfilled refill, and then use a different seal (Cheat seal lng), ultrasonic compression or use of gel structure 1 After the 0 4 and the air-permeable structure 1 06 are stacked, the remaining edges other than the reserved edges are sealed together. When the bag is applied continuously, the food can be passed afterwards, and then the opening can be sealed again to place the food in the layer. As for the method of sealing the opening, there are many methods. As one application example of the present invention, a set of sealing strips 40 can be provided on the application surface of the packaging bag, and the grooves and convex strips are connected to each other for convenience. Make it convenient. After the seal is added, the user only needs to put in or take out the food or the surface to be processed at any time. When the user puts in the articles or food, he can only tightly close the packaging bag and put it in the microwave oven. The user can use the breathable film and technique of the present invention in combination, and can use the sealed packing bag (sliding zipper structure, which can also be used for sealing and unsealing the opening 50) which is applied by the present invention multiple times. Adopt direct adhesive tape bonding and super-heat pressing method. The breathable material film packaging bag of the present invention is practically applied to various foods and extended applications, such as raw food, popcorn or other items. When such openings 50, in a convenient way, such as heating and pressing the tape, the air-permeable unsealed opening 50 is sealed into the sealed packaging bag film as shown in Figure 6, two inside the opening 50 (Groove and rib) When the user opens and closes the article to open the seal, the other party needs to press the seal, which is a technically breathable packaging bag that is heated in a hot water bath. (Sealable recloseable bag can be used.) Sonic compression or use plus can be used to package fresh meat food, cold; East items are sealed in the hair

H-OZ / ZZ V. Description of the invention (18) When the air-permeable packaging gas, water-cooked or red-cooked, the food with the crack of the food seal still in the package is divided into the temperature and vapor pressure of the heat-insulated packaging bag. At the critical value, the deformation expands, and its breathability prevents the joint material from forming closed cracks after an instant cooking, and then the invention uses the article to heat up for a long time, or it decreases simultaneously for a long time, and the joint layer is not as explosive at the same time. The found material will be airtight and tightly sealed with its breathability. Its main efficiency is that it adds less cooking bags after cooking. The cooking line is heated outside the bag. The inside of the bag is effectively lifted by vibration. The sealing of the caulk is like a bag-like gas-tight seal. Due to the temperature structure and the cooling material, the stored food must have special properties. If it needs to be cooked, it can be directly heated and other methods to add the initial stage. The food is The vapor pressure is more uniform than the airtight state, and the friction and conversion are uniform. The food is heated even when the air pressure inside the packaging bag is expanded outward. The sealing material capacity of the film layer is reduced. When the packaging bag is cooled down, it will be lowered and solidified, so that the gas in the bag will shrink and have the function of film-like packaging bags. Besides, it will prevent the loss of volatilization of wine and volatile oil. It is absolutely hot, and it will be safe when the material changes. Another bag of film seals the product. It also seems to contain the package. It can avoid the spices. This can be microwaved under pressure. The film is soft and the cracks are completely leaked. The characteristics of cracking will be due to the empty receiving furnaces, high temperature and environmentally friendly packaging and microwaves. The cracks will be directly heated to atmospheric pressure, the cracks will become thin, and they will become pressure valves. Vapor pressure applications For the seam will be added and packaged in a bag-packed style to uniformly avoid excessive food and other ingredients, because to maintain food, it is more worthwhile / benefit steaming microwave. At this time, the energy on the bag is similar to that of the bag. The subsequent cracking has such an effect that when the force is too large, the heat seals and changes the film again.
