Description

感壓標籤Pressure sensitive label

本發明係關於一種感壓標籤，特別是一種具有蛋白質層的感壓標籤。The present invention relates to a pressure sensitive label, particularly a pressure sensitive label with a protein layer.

目前食品廠商為了延長食品的保存期限，通常會採用超高壓技術(high pressure processing，HPP)來對於食品進行加工。所謂的超高壓技術係指將以液體(通常為水)作為傳遞壓力的介質，使其存在於超高壓(例如100MPa以上)環境下，同時搭配適當的時間與溫度(例如50℃以下)，進行食品的物理性處理，進而達到食品加工、保存及滅菌之目的。At present, in order to extend the shelf life of food, food manufacturers usually use high pressure processing (HPP) to process food. The so-called ultra-high pressure technology refers to the use of liquid (usually water) as the medium to transfer pressure, so that it exists in an ultra-high pressure (for example, 100MPa or more) environment, and at the same time, with appropriate time and temperature (for example, 50°C or less). The physical treatment of food, and then achieve the purpose of food processing, preservation and sterilization.

目前廠商在宣傳其所生產之食品的時候，通常會採用其生產的食品有經過高壓處理程序等宣傳用語，以強調食品的食用安全性。然而，大部分的廠商僅是單純利用文字或話語說明其生產之食品有經過高壓處理，而未透過其他手段向消費者實際證明食品加壓之壓力是否達到標準，故消費者仍對於食品的食用安全性仍存有疑慮。因此，如何證明食品已經過標準加壓壓力處理儼然已成為此領域的研發人員急待解決的問題之一。At present, when manufacturers promote the food they produce, they usually use the words that the food they produce has undergone high-pressure processing to emphasize the safety of the food. However, most manufacturers simply use words or words to explain that the food they produce has undergone high-pressure treatment, without actually using other means to prove to consumers whether the pressure of the food is up to the standard, so consumers are still concerned about food consumption There are still doubts about security. Therefore, how to prove that the food has undergone standard pressure treatment has become one of the urgent problems for researchers in this field.

本發明在於提供一種感壓標籤，藉以解決先前技術所述之廠商未實際證明食品加壓之壓力是否達到標準，而讓消費者對於食品仍存有疑慮的問題。The present invention is to provide a pressure-sensitive label to solve the problem that the manufacturers described in the prior art have not actually proved whether the pressure of the food pressurization meets the standard, and consumers still have doubts about the food.

本發明之一實施例所揭露之一種感壓標籤，用以附著於一撓性包材，包含一基材層、一護膜層及一蛋白質層。基材層有相對的一第一附著面及一第二附著面，第一附著面用以附著於撓性包材。護膜層附著於基材層的第二附著面，且基材層與護膜層共同形成一容置空間。蛋白質層經由芳香族胺基酸組成，其設置於容置空間，蛋白質層具有至少一壓力測定區。當至少一壓力測定區所受到的壓力大於或等於一臨界壓力值時，至少一壓力測定區自一初始資訊改變為一壓力識別資訊。A pressure-sensitive label disclosed in an embodiment of the present invention is used for attaching to a flexible packaging material, and includes a substrate layer, a protective film layer and a protein layer. The substrate layer has a first attachment surface and a second attachment surface opposite to each other, and the first attachment surface is used for attaching to the flexible packaging material. The protective film layer is attached to the second attachment surface of the base material layer, and the base material layer and the protective film layer together form an accommodating space. The protein layer is composed of aromatic amino acids and is arranged in the accommodating space. The protein layer has at least one pressure measuring area. When the pressure received by the at least one pressure measurement area is greater than or equal to a critical pressure value, the at least one pressure measurement area changes from an initial information to a pressure identification information.

根據上述實施例之感壓標籤，由於感壓標籤之蛋白質層的壓力測定區受到壓力大於或等於其臨界壓力值時，壓力測定區會自初始資訊改變為壓力識別資訊，故消費者可從附著於撓性包材上之感壓標籤的壓力測定區之資訊，判斷撓性包材內的食品是否確實經過加壓處理，且加壓之壓力是否達到標準。According to the pressure-sensitive label of the above embodiment, since the pressure measurement area of the protein layer of the pressure-sensitive label receives a pressure greater than or equal to its critical pressure value, the pressure measurement area will change from initial information to pressure identification information, so consumers can change from the attachment Use the information in the pressure measurement area of the pressure sensitive label on the flexible packaging material to determine whether the food in the flexible packaging material has actually been pressurized and whether the pressurized pressure meets the standard.

以上關於本發明內容的說明及以下實施方式的說明係用以示範與解釋本發明的原理，並且提供本發明的專利申請範圍更進一步的解釋The above description of the content of the present invention and the description of the following embodiments are used to demonstrate and explain the principle of the present invention, and provide a further explanation of the scope of the patent application of the present invention

請參閱圖1至圖3。圖1為根據本發明第一實施例所述之感壓標籤附著於撓性包材的立體示意圖。圖2為圖1之感壓標籤的分解示意圖。圖3為圖1之感壓標籤的剖視示意圖。Please refer to Figure 1 to Figure 3. Fig. 1 is a perspective view of the pressure-sensitive label attached to a flexible packaging material according to the first embodiment of the present invention. Fig. 2 is an exploded schematic diagram of the pressure sensitive label of Fig. 1. 3 is a schematic cross-sectional view of the pressure-sensitive label of FIG. 1.

本實施例揭露了一感壓標籤1a。感壓標籤1a例如用以附著於一撓性包材2。此撓性包材2例如為用來裝食品的包裝袋或瓶子。感壓標籤1a包含一基材層10a、一蛋白質層20a、一護膜層30a及一黏膠層40a。This embodiment discloses a pressure sensitive label 1a. The pressure sensitive label 1a is used to attach to a flexible packaging material 2, for example. The flexible packaging material 2 is, for example, a packaging bag or a bottle used to hold food. The pressure-sensitive label 1a includes a substrate layer 10a, a protein layer 20a, a protective film layer 30a, and an adhesive layer 40a.

基材層10a的材質例如為聚對苯二甲酸乙二酯、棉紙、不織布或泡棉。基材層10a具有相對的一第一附著面11a及一第二附著面12a。蛋白質層20a疊設於基材層10a的第二附著面12a。The material of the base layer 10a is, for example, polyethylene terephthalate, tissue paper, non-woven fabric, or foam. The substrate layer 10a has a first adhesion surface 11a and a second adhesion surface 12a opposite to each other. The protein layer 20a is stacked on the second attachment surface 12a of the base layer 10a.

護膜層30a的材質例如為聚對苯二甲酸乙二酯、聚丙烯或聚乙烯。護膜層30a例如為透明的片材，其具有一第一表面31a、一第二表面32a及一容置槽33a。護膜層30a的第一表面31a相對於第二表面32a，且容置槽33a位於第一表面31a。護膜層30a的第一表面31a例如透過黏附的方式附著於基材層10a的第二附著面12a，且護膜層30a的容置槽33a與基材層10a的第二附著面12a共同形成一容置空間50a。蛋白質層20a是位於此容置空間50a內，而受到護膜層30a及基材層10a的包覆，以避免外界物質(例如清潔劑或尿素等)汙染蛋白質層20a。在本實施例中，護膜層30a透過黏附的方式附著於基材層10a的用意在於，因為基材層10a上的蛋白質層20a容易因熱而變質，故避免採用有高溫影響的熱壓方式結合護膜層30a與基材層10a，而採用不會有高溫影響的黏附方式結合護膜層30a與基材層10a。The material of the protective film layer 30a is, for example, polyethylene terephthalate, polypropylene, or polyethylene. The protective film layer 30a is, for example, a transparent sheet, which has a first surface 31a, a second surface 32a, and a receiving groove 33a. The first surface 31a of the protective film layer 30a is opposite to the second surface 32a, and the containing groove 33a is located on the first surface 31a. The first surface 31a of the protective film layer 30a is attached to the second attachment surface 12a of the base layer 10a, for example, by adhesion, and the accommodating groove 33a of the protective film layer 30a and the second attachment surface 12a of the base layer 10a are formed together A accommodating space 50a. The protein layer 20a is located in the accommodating space 50a, and is covered by the protective film layer 30a and the substrate layer 10a to prevent contamination of the protein layer 20a by foreign substances (such as detergent or urea). In this embodiment, the protective film layer 30a is attached to the substrate layer 10a through adhesion, because the protein layer 20a on the substrate layer 10a is easily deteriorated by heat, so avoid using hot pressing methods that have high temperature effects. The protective film layer 30a and the base material layer 10a are combined, and the protective film layer 30a and the base material layer 10a are combined by an adhesion method that is not affected by high temperature.

黏膠層40a附著於基材層10a的第一附著面11a，基材層10a的第一附著面11a用以透過黏膠層40a附著於撓性包材2。The adhesive layer 40a is attached to the first attachment surface 11a of the substrate layer 10a, and the first attachment surface 11a of the substrate layer 10a is used to attach to the flexible packaging material 2 through the adhesive layer 40a.

在本實施例中，蛋白質層20a例如是經由芳香族胺基酸組成。更詳細來說，蛋白質層20a具有沿一排列方向D並排排列的四個壓力測定區21a、22a、23a、24a。這些壓力測定區21a、22a、23a、24a的材質皆選自由色胺酸、酪胺酸及苯丙胺酸所構成的群組，且這些壓力測定區21a、22a、23a、24a的材質彼此相異。舉例來說，壓力測定區21a的材質為色胺酸及酪胺酸的組合，壓力測定區22a的材質為酪胺酸及苯丙胺的組合，壓力測定區23a的材質為色胺酸及苯丙胺酸的組合，且壓力測定區24a的材質為色胺酸、酪胺酸及苯丙胺酸之組合。In this embodiment, the protein layer 20a is composed of, for example, an aromatic amino acid. In more detail, the protein layer 20a has four pressure measurement areas 21a, 22a, 23a, 24a arranged side by side along an arrangement direction D. The materials of the pressure measuring areas 21a, 22a, 23a, 24a are selected from the group consisting of tryptophan, tyrosine, and phenylalanine, and the materials of the pressure measuring areas 21a, 22a, 23a, 24a are different from each other. For example, the material of the pressure measurement area 21a is a combination of tryptophan and tyrosine, the material of the pressure measurement area 22a is a combination of tyrosine and amphetamine, and the material of the pressure measurement area 23a is a combination of tryptophan and amphetamine. The combination, and the material of the pressure measuring area 24a is a combination of tryptophan, tyrosine and amphetamine.

當這些壓力測定區21a、22a、23a、24a各別所受到的壓力大於或等於一臨界壓力值時，這些壓力測定區21a、22a、23a、24a自一初始資訊改變為一壓力識別資訊。在本實施例中，初始資訊及壓力識別資訊例如為顏色。即，初始資訊例如為原色，而壓力識別資訊例如為壓力識別色。這些壓力測定區21a、22a、23a、24a之這些臨界壓力值彼此相異，這些壓力測定區的這些臨界壓力值於排列方向D上由小至大，且這些壓力測定區21a、22a、23a、24a的這些壓力識別色彼此相異，以下段落將舉例說明。When the pressure received by the pressure measurement areas 21a, 22a, 23a, 24a is greater than or equal to a critical pressure value, the pressure measurement areas 21a, 22a, 23a, 24a change from an initial information to a pressure identification information. In this embodiment, the initial information and pressure identification information are, for example, colors. That is, the initial information is, for example, a primary color, and the pressure recognition information is, for example, a pressure recognition color. The critical pressure values of the pressure measurement areas 21a, 22a, 23a, 24a are different from each other, and the critical pressure values of the pressure measurement areas are from small to large in the arrangement direction D, and the pressure measurement areas 21a, 22a, 23a, These pressure recognition colors of 24a are different from each other, and the following paragraphs will illustrate them.

首先，壓力測定區21a的臨界壓力值例如為1.1 bar，且壓力測定區21a的原色例如為暗紅色。壓力測定區22a的臨界壓力值例如為1000 bar，且壓力測定區22a的原色例如為白色。壓力測定區23a的臨界壓力值例如為3000 bar，且壓力測定區23a的原色例如為白色。壓力測定區24a的臨界壓力值例如為6000 bar，且壓力測定區24a的原色例如為白色。First, the critical pressure value of the pressure measurement area 21a is, for example, 1.1 bar, and the primary color of the pressure measurement area 21a is, for example, dark red. The critical pressure value of the pressure measurement area 22a is, for example, 1000 bar, and the primary color of the pressure measurement area 22a is, for example, white. The critical pressure value of the pressure measurement area 23a is, for example, 3000 bar, and the primary color of the pressure measurement area 23a is, for example, white. The critical pressure value of the pressure measurement area 24a is, for example, 6000 bar, and the primary color of the pressure measurement area 24a is, for example, white.

接著，以下之說明請搭配表1，表1為壓力測定區21a、22a、23a、24a在受到位於不同區間之壓力後所呈現的顏色。以下將假設撓性包材2內食品所需之滅菌加壓需求為3000 bar以上。Next, please use Table 1 for the following description. Table 1 shows the colors of the pressure measurement areas 21a, 22a, 23a, and 24a after being subjected to pressure in different intervals. The following assumes that the sterilization and pressurization requirement for the food in the flexible packaging material 2 is above 3000 bar.

表1 Table 1   To 壓力 測定區21a pressure Measurement area 21a 壓力 測定區22a pressure Measurement area 22a 壓力 測定區23a pressure Measurement area 23a 壓力 測定區24a pressure Measurement area 24a 1.1bar>P 1.1bar>P 暗紅色 dark red 白色 white 白色 white 白色 white 1000bar>P≧1.1bar 1000bar>P≧1.1bar 白色 white 白色 white 白色 white 白色 white 3000bar>P≧1000bar 3000bar>P≧1000bar 白色 white 黃綠色 yellow-green 白色 white 白色 white 6000bar>P≧3000bar 6000bar>P≧3000bar 白色 white 黃綠色 yellow-green 綠色 green 白色 white P≧6000bar P≧6000bar 白色 white 黃綠色 yellow-green 綠色 green 藍色 blue

當這些壓力測定區21a、22a、23a、24a受到的壓力小於1.1 bar時，這些壓力測定區21a、22a、23a、24a會維持於原色，即分別為暗紅色、白色、白色及白色。假若消費者看到撓性包材2上的壓力測定區21a、22a、23a、24a分別為暗紅色、白色、白色及白色，則可判斷出位於撓性包材2內的食品在製造過程中所承受的壓力小於1.1 bar，即可得知位於撓性包材2內的食品僅於一般環境中加工，而未經過加壓處理。When these pressure measurement areas 21a, 22a, 23a, 24a receive pressures less than 1.1 bar, these pressure measurement areas 21a, 22a, 23a, 24a will maintain the original colors, namely dark red, white, white, and white, respectively. If the consumer sees that the pressure measurement areas 21a, 22a, 23a, 24a on the flexible packaging material 2 are dark red, white, white, and white, respectively, it can be judged that the food in the flexible packaging material 2 is in the manufacturing process If the pressure is less than 1.1 bar, it can be known that the food in the flexible packaging material 2 is only processed in a general environment and has not been subjected to pressure treatment.

當這些壓力測定區21a、22a、23a、24a受到的壓力大於等於1.1 bar且小於1000 bar時，壓力測定區21a會從原色轉變為壓力識別色，而其他壓力測定區22a、23a、24a會維持於原色。即，壓力測定區21a會從暗紅色轉變為白色，而壓力測定區22a、23a、24a則維持於白色。假若消費者看到撓性包材2上之壓力測定區21a、22a皆為白色，則可判斷出撓性包材1內之食品所受到壓力雖大於1.1 bar但未達1000 bar。因此，在撓性包材2內的食品所需之滅菌加壓需求為3000 bar以上的前提下，即判斷撓性包材2之食品所經加壓的壓力不符標準。When the pressure on these pressure measurement areas 21a, 22a, 23a, 24a is greater than or equal to 1.1 bar and less than 1000 bar, the pressure measurement area 21a will change from the original color to the pressure recognition color, and the other pressure measurement areas 22a, 23a, 24a will maintain In the primary colors. That is, the pressure measurement area 21a changes from dark red to white, while the pressure measurement areas 22a, 23a, and 24a remain white. If the consumer sees that the pressure measurement areas 21a and 22a on the flexible packaging material 2 are all white, it can be judged that the pressure of the food in the flexible packaging material 1 is greater than 1.1 bar but less than 1000 bar. Therefore, under the premise that the sterilization and pressurization requirement of the food in the flexible packaging material 2 is more than 3000 bar, it is judged that the pressurized pressure of the food in the flexible packaging material 2 does not meet the standard.

當這些壓力測定區21a、22a、23a、24a受到的壓力大於等於1000 bar且小於3000 bar時，壓力測定區21a、22a分別會從原色轉變為壓力識別色，而其他壓力測定區23a、24a會維持於原色。即，壓力測定區21a從暗紅色轉變為白色，壓力測定區22a從白色轉變為黃綠色，而壓力測定區23a、24a維持於白色。假若消費者看到撓性包材2上之壓力測定區22a、23a分別為黃綠色及白色，則可判斷出撓性包材2內之食品所受到壓力雖大於1000 bar但未達3000 bar。因此，在撓性包材2內的食品所需之滅菌加壓需求為3000 bar以上的前提下，即判斷撓性包材2之食品所經加壓的壓力不符標準。When the pressure of these pressure measurement areas 21a, 22a, 23a, 24a is greater than or equal to 1000 bar and less than 3000 bar, the pressure measurement areas 21a, 22a will change from the original color to the pressure identification color, and the other pressure measurement areas 23a, 24a will Maintain the original color. That is, the pressure measurement area 21a changes from dark red to white, the pressure measurement area 22a changes from white to yellow-green, and the pressure measurement areas 23a and 24a remain white. If the consumer sees that the pressure measurement areas 22a and 23a on the flexible packaging material 2 are yellow-green and white respectively, it can be judged that the pressure of the food in the flexible packaging material 2 is greater than 1000 bar but less than 3000 bar. Therefore, under the premise that the sterilization and pressurization requirement of the food in the flexible packaging material 2 is more than 3000 bar, it is judged that the pressurized pressure of the food in the flexible packaging material 2 does not meet the standard.

當這些壓力測定區21a、22a、23a、24a受到的壓力大於等於3000 bar且小於6000 bar時，壓力測定區21a、22a、23a分別會從原色轉變為壓力識別色，而壓力測定區24a會維持於原色。即，壓力測定區21a從暗紅色轉變為白色，壓力測定區22a從白色轉變為黃綠色，壓力測定區23a從白色轉變為綠色，而壓力測定區24a維持於白色。假若消費者看到撓性包材2上之壓力測定區23a、24a分別為綠色及白色，則可判斷出撓性包材2內之食品所受到壓力大於3000 bar但未達6000 bar。因此，在撓性包材2內的食品所需之滅菌加壓需求為3000 bar以上的前提下，即判斷撓性包材2之食品所經加壓的壓力符合標準。When these pressure measurement areas 21a, 22a, 23a, 24a receive a pressure greater than or equal to 3000 bar and less than 6000 bar, the pressure measurement areas 21a, 22a, 23a will change from the original color to the pressure identification color, and the pressure measurement area 24a will maintain In the primary colors. That is, the pressure measurement area 21a changes from dark red to white, the pressure measurement area 22a changes from white to yellow-green, the pressure measurement area 23a changes from white to green, and the pressure measurement area 24a remains white. If the consumer sees that the pressure measurement areas 23a and 24a on the flexible packaging material 2 are green and white, respectively, it can be judged that the pressure of the food in the flexible packaging material 2 is greater than 3000 bar but less than 6000 bar. Therefore, under the premise that the sterilization and pressurization requirement for the food in the flexible packaging material 2 is more than 3000 bar, it is determined that the pressurized pressure of the food in the flexible packaging material 2 meets the standard.

當這些壓力測定區21a、22a、23a、24a受到的壓力大於等於6000 bar時，壓力測定區21a、22a、23a、24a分別會從原色轉變為壓力識別色。即，壓力測定區21a從暗紅色轉變為白色，壓力測定區22a從白色轉變為黃綠色，壓力測定區23a從白色轉變為綠色，且壓力測定區24a從白色轉變為藍色。假若消費者看到撓性包材2上之壓力測定區24a為藍色，則可判斷出撓性包材2內之食品所受到壓力大於6000 bar。因此，在撓性包材2內的食品所需之滅菌加壓需求為3000 bar以上的前提下，即判斷撓性包材2之食品所經加壓的壓力符合標準。When these pressure measurement areas 21a, 22a, 23a, 24a receive a pressure greater than or equal to 6000 bar, the pressure measurement areas 21a, 22a, 23a, 24a will change from the original color to the pressure recognition color, respectively. That is, the pressure measurement area 21a changes from dark red to white, the pressure measurement area 22a changes from white to yellow-green, the pressure measurement area 23a changes from white to green, and the pressure measurement area 24a changes from white to blue. If the consumer sees that the pressure measuring area 24a on the flexible packaging material 2 is blue, it can be judged that the pressure of the food in the flexible packaging material 2 is greater than 6000 bar. Therefore, under the premise that the sterilization and pressurization requirement for the food in the flexible packaging material 2 is more than 3000 bar, it is determined that the pressurized pressure of the food in the flexible packaging material 2 meets the standard.

從上述之內容可知，由於感壓標籤1a之蛋白質層20a的壓力測定區21a、22a、23a、24a受到壓力大於或等於其臨界壓力值時，壓力測定區21a、22a、23a、24a會自原色改變為壓力識別色，故消費者可從附著於撓性包材2上之感壓標籤1a的壓力測定區21a、22a、23a、24a之顏色，判斷撓性包材2內的食品是否確實經過加壓處理，且加壓之壓力是否達到標準。It can be seen from the above content that the pressure measurement areas 21a, 22a, 23a, 24a of the protein layer 20a of the pressure-sensitive label 1a will be changed from the original color when the pressure is greater than or equal to the critical pressure value. Change to the pressure identification color, so consumers can judge whether the food in the flexible packaging material 2 has actually passed through the color of the pressure measurement areas 21a, 22a, 23a, 24a of the pressure sensitive label 1a attached to the flexible packaging material 2 Pressurized treatment, and whether the pressurized pressure meets the standard.

在本實施例中，蛋白質層20a並不限具有四個壓力測定區21a、22a、23a、24a。在其他實施例中，可依據實際需求將蛋白質層的數量調整為小於四個或大於四個。In this embodiment, the protein layer 20a is not limited to have four pressure measurement areas 21a, 22a, 23a, 24a. In other embodiments, the number of protein layers can be adjusted to less than four or more than four according to actual needs.

此外，上述之壓力測定區21a、22a、23a、24a的臨界壓力值的大小、原色及壓力識別色之顏色僅是舉例說明，並非用以限定本發明。在其他實施例中，可依據需求調整壓力測定區的臨界壓力值的大小、原色及壓力識別色之顏色。In addition, the size of the critical pressure value, the primary color, and the color of the pressure identification color of the pressure measurement areas 21a, 22a, 23a, and 24a described above are only examples, and are not intended to limit the present invention. In other embodiments, the size of the critical pressure value of the pressure measurement area, the primary color, and the color of the pressure identification color can be adjusted according to requirements.

另外，在本實施例中，上述之壓力測定區21a、22a、23a、24a的顏色係可經由肉眼直接判斷，但並不以此為限。在其他實施例中，壓力測定區的顏色可為肉眼無法直接判斷，而係可經由其他介質或光學儀器來將肉眼無法判斷之壓力測定區的顏色轉換為肉眼可直接判斷的顏色。In addition, in this embodiment, the color of the pressure measurement areas 21a, 22a, 23a, 24a can be directly judged by the naked eye, but it is not limited thereto. In other embodiments, the color of the pressure measurement area may not be directly judged by the naked eye, and other media or optical instruments may be used to convert the color of the pressure measurement area that cannot be judged by the naked eye into a color that can be directly judged by the naked eye.

此外，前述之初始資訊及壓力識別資訊是以顏色為例，但並不此為限。在其他實施例中，初始資訊及壓力識別資訊可以是數值，且此數值可為光譜、透光度、吸光度或偏光度。在壓力測定區受到大於或等於臨界壓力值之壓力之後，壓力測定區之數值會產生變化。就消費者方面，可經由光學儀器偵測壓力測定區的數值，來判斷撓性包材內之食品是否確實經過加壓處理且加壓之壓力是否達到標準。In addition, the aforementioned initial information and pressure identification information are based on color as an example, but not limited to this. In other embodiments, the initial information and the pressure identification information may be numerical values, and the numerical values may be spectrum, transmittance, absorbance, or polarization. After the pressure measurement area receives a pressure greater than or equal to the critical pressure value, the value of the pressure measurement area will change. As far as consumers are concerned, optical instruments can be used to detect the value of the pressure measurement area to determine whether the food in the flexible packaging material is actually pressurized and whether the pressurized pressure meets the standard.

Fig. 4 is an exploded schematic diagram of the pressure sensitive label according to the second embodiment of the present invention. Fig. 5 is a schematic cross-sectional view of the pressure-sensitive label of Fig. 4.

本實施例揭露了一感壓標籤1b，其類似於圖1的感壓標籤1a，故以下僅針對二者之間的差異處進行描述，關於相似的部分則不再贅述。This embodiment discloses a pressure-sensitive label 1b, which is similar to the pressure-sensitive label 1a in FIG. 1. Therefore, only the differences between the two are described below, and the similar parts are omitted.

在本實施例的感壓標籤1b中，基材層10b具有位於第二附著面12b的一容置槽13b，且容置槽13b與護膜層30b的第一表面31b共同形成容置空間50b。蛋白質層20b位於容置空間50b內，並受到基材層10b及護膜層30b的包覆。In the pressure-sensitive label 1b of this embodiment, the substrate layer 10b has an accommodation groove 13b located on the second attachment surface 12b, and the accommodation groove 13b and the first surface 31b of the protective film layer 30b jointly form an accommodation space 50b . The protein layer 20b is located in the accommodating space 50b and is covered by the substrate layer 10b and the protective film layer 30b.

根據上述實施例之感壓標籤，由於感壓標籤之蛋白質層的壓力測定區受到壓力大於或等於其臨界壓力值時，壓力測定區會自初始資訊改變為壓力識別資訊，故消費者可從附著於撓性包材上之感壓標籤的壓力測定區之資訊，判斷軟性包材內的食品是否確實經過加壓處理，且加壓之壓力是否達到標準。According to the pressure-sensitive label of the above embodiment, since the pressure measurement area of the protein layer of the pressure-sensitive label receives a pressure greater than or equal to its critical pressure value, the pressure measurement area will change from initial information to pressure identification information, so consumers can change from the attachment Use the information in the pressure measurement area of the pressure sensitive label on the flexible packaging material to determine whether the food in the flexible packaging material has actually been pressurized and whether the pressurized pressure meets the standard.

雖然本發明以前述之諸項實施例揭露如上，然其並非用以限定本發明，任何熟習相像技藝者，在不脫離本發明之精神和範圍內，當可作些許之更動與潤飾，因此本發明之專利保護範圍須視本說明書所附之申請專利範圍所界定者為準。Although the present invention is disclosed in the foregoing embodiments as described above, it is not intended to limit the present invention.
