Abstract
Description
本創作係有關一種加熱可移除標籤,其具有良好印刷性及加熱可移除之效果,移除後不殘膠,使用於印刷包裝技術領域。 This creation is related to a heat-removable label, which has good printability and heat-removable effect . After removal, there is no residual glue. It is used in the field of printing and packaging technology.
目前市面上已知加熱可移除標籤,其承載膜層為一熱收縮膜(台灣新型專利公告號碼:M535642)。該熱收縮膜其生產製造時因雙向延伸率不同,以致該加熱可移除標籤在加熱時容易出現雙向收縮率不均勻,而無法達到穩定的加熱可移除之效果。 Currently, there are known heat-removable labels on the market, and the carrier film is a heat shrinkable film (Taiwan New Patent Publication Number: M535642). The heat shrinkable film is produced due to different bidirectional elongation rates, so that the heated removable label is prone to uneven bidirectional shrinkage rate during heating, and cannot achieve a stable heating removable effect .
本創作為一種加熱可移除標籤,其感壓膠層中至少含有一種可熱膨脹性微球體以形成一加熱可熱膨脹感壓膠層,該加熱可熱膨脹感壓膠層經過加熱後可讓該加熱可移除標籤達到穩定的加熱可移除之效果。因此,完成本創作加熱可移除標籤。 This creation is a heat-removable label. The pressure-sensitive adhesive layer contains at least one heat-expandable microsphere to form a heat-expandable pressure-sensitive adhesive layer. The heated heat-expandable pressure-sensitive adhesive layer can be heated after heating. The removable label achieves a stable heating and removable effect . Therefore, the label can be removed by heating to complete this creation.
本創作的技術內容說明如下,該項說明為實施例,並非用來侷限本創作的專利保護範圍。 The technical content of this creation is described as follows. This description is an example and is not used to limit the scope of patent protection of this creation.
本創作為一種加熱可移除標籤,其結構由上而下包括第一層承載膜層、第二層底膠層、第三層加熱可熱膨脹感壓膠層及第四層離型層。 This creation is a heat-removable label, and its structure from top to bottom includes a first layer of carrier film, a second layer of primer layer, a third layer of heat-expandable pressure sensitive adhesive layer and a fourth layer of release layer.
本創作為一種加熱可移除標籤,其中第一層承載膜層所使用 的材料,包括珠光紙或合成紙,其厚度為30~100微米(μm),其厚度38~75微米(μm)為較佳者。 This creation is a heated removable label, in which the first layer of carrier film is used The material includes pearl paper or synthetic paper, with a thickness of 30-100 microns (μm), and a thickness of 38-75 microns (μm) is preferred.
本創作為一種加熱可移除標籤,其中第二層底膠層為壓克力系底膠,其厚度為1~10微米(μm),其厚度3~8微米(μm)為較佳者。 This creation is a heat-removable label, in which the second primer layer is acrylic primer with a thickness of 1-10 microns (μm), and a thickness of 3-8 microns (μm) is better.
本創作為一種加熱可移除標籤,其中第三層加熱可熱膨脹感壓膠層之感壓膠,其包括壓克力系感壓膠或橡膠系感壓膠,且其中至少含有一種可熱膨脹性微球體。其中加熱可熱膨脹感壓膠層的厚度為15~40微米(μm),其厚度20~30微米(μm)為較佳者。 This creation is a heat-removable label, in which the third layer of heat-expandable pressure-sensitive adhesive includes acrylic pressure-sensitive adhesive or rubber-based pressure-sensitive adhesive, and contains at least one heat-expandable adhesive. Microspheres. The thickness of the heat-expandable pressure-sensitive adhesive layer is 15-40 micrometers (μm), and the thickness of 20-30 micrometers (μm) is preferred.
本創作為一種加熱可移除標籤,其中第四層離型層所使用的材料包括紙及塑膠薄膜,其厚度為25~150微米(μm),其厚度38~100微米(μm)為較佳者。 This creation is a heat-removable label. The materials used for the fourth release layer include paper and plastic film. Its thickness is 25~150 microns (μm), and its thickness is 38-100 microns (μm). By.

圖式1為一種加熱可移除標籤的結構示意圖。 Figure 1 is a schematic structural diagram of a heated removable label.
如圖式1所示,本創作係有關一種加熱可移除標籤,其經印刷成各種圖案及模切成各種形狀,其包括承載膜層(1)、底膠層(2)、加熱可熱膨脹感壓膠層(3)及離型層(4)。其中第一層承載膜層使用珠光紙,其厚度為54微米(μm);第二層壓克力系底膠層,其厚度為5微米(μm);第三層加熱可熱膨脹感壓膠層為壓克力系感壓膠且含有一種可熱膨脹性微球體,其厚度25微米(μm);第四層離型層為聚酯薄膜,其厚度為50微米(μm)。 As shown in Figure 1, this creation is related to a heating removable label, which is printed into various patterns and die-cut into various shapes, which includes a carrier film layer (1), a primer layer (2), and a heat-expandable label. Pressure sensitive adhesive layer (3) and release layer (4). The first carrier film layer uses pearl paper with a thickness of 54 microns (μm); the second laminated acrylic primer layer has a thickness of 5 microns (μm); the third layer is heated and expandable pressure sensitive adhesive layer It is an acrylic pressure-sensitive adhesive and contains a thermally expandable microsphere with a thickness of 25 microns (μm); the fourth release layer is a polyester film with a thickness of 50 microns (μm).
前述本創作實施例所得標籤產品,經測試結果,標籤在90℃及1%鹼水(氫氧化鈉)浴中,經過3分鐘後其加熱可熱膨脹感壓膠層會均勻 的加熱膨脹而失去黏性,亦即此標籤可以穩定的從啤酒瓶脫離,經觀察發現沒有殘膠存在,可完全滿足啤酒瓶回收再利用的要求。本創作一種加熱可移除標籤具有產業利用性,且合乎新型專利要件。
