Description

具防偽功能之RFID標籤結構及其製造方法
本發明係有關於一種RFID標籤結構及其製造方法,尤其是一種可防止RFID標籤被重複使用,而達到防偽目的之RFID標籤結構及其製造方法。
無線射頻辨識(RFID)標籤(tag)除了可記載產品出處、製造過程、物流品質,以進行各項管理外,其亦可利用標籤所含晶片中的特殊編碼,而達到防偽功能。因此,以無線射頻辨識標籤執行產品身分之辨識及防偽,為目前之趨勢。
請參照圖1,其繪示習知無線射頻辨識標籤之應用示意圖。如圖1所示,目前之無線射頻辨識標籤100於應用時,係將無線射頻辨識標籤100貼附於一貼附物200上,其中,該貼附物200可為但不限於為塑膠膜,在不破壞無線射頻辨識標籤100之情形下,劃幾條切割線210,當要將無線射頻辨識標籤100從貼附物200移除時,會沿切割線210將該無線射頻辨識標籤100上之圖案110破壞掉,而達到防偽及防止該無線射頻辨識標籤100被重複使用之情形。但是,有心人士小心移除時,仍可將該圖案110完整取下,使該無線射頻辨識標籤100可被重複使用,如此將失去該無線射頻辨識標籤100之唯一性,誠屬美中不足之處。
本發明之一目的係提供一種具防偽功能之RFID標籤結構及其製造方法,其係利用材質間附著力之差異,使已黏附在平整表面之RFID標籤經移除時,RFID標籤上之圖案因與基材間之附著力較低而脫離基材,以防止該RFID標籤被重複使用,而達到防偽、防盜之目的。
為達上述之目的,本發明之一種具防偽功能之RFID標籤結構,其包括:一基材;一圖案,係形成於該基材之一表面上;以及一黏膠層,係附著於該圖案之另一未與該基材接觸之表面上,其中該黏膠層之黏性係大於該圖案與該基材間之黏性,且可被黏附於一貼附物上,而形成一RFID標籤;當該RFID標籤被剝離該貼附物時,該基材即脫離該貼附物,而該圖案及黏膠層仍黏附於該貼附物上,以防止該RFID標籤被重複使用。
為達上述之目的,本發明之一種具防偽功能之RFID標籤之製造方法,其包括下列步驟:將一圖案以內含催化成分之油墨印製於一基材上;經乾燥或烘乾後,該油墨與該基材反應產生一第一附著力;再將含有該油墨之該基材浸置於含金屬離子之溶液中,該油墨所含催化成分促使溶液內之金屬離子產生反應而令金屬沈積於油墨上,形成具導電作用之該圖案;最末在該圖案上塗上一層具第二附著力之一黏膠層,且該第二附著力大於該第一附著力。
為使 貴審查委員能進一步瞭解本發明之結構、特徵及其目的,茲附以圖式及較佳具體實施例之詳細說明如后。
請一併參照圖2及圖3,其中圖2繪示本案一較佳實施例之具防偽功能之RFID標籤結構之剖面示意圖;圖3繪示本案一較佳實施例之具防偽功能之RFID標籤被剝離貼附物之示意圖。
如圖所示,本案之具防偽功能之RFID標籤結構,其包括:一基材10;一圖案20;以及一黏膠層30。
其中,該基材10係可承載該圖案20,其可為但不限於為PET(Polyethylene terephthalatepet)、PI(Polyimide)、PVC(Polyvinyl chloride)薄膜,或PET、PI、PVC薄膜與貼紙之複合物。
該圖案20係形成於該基材10之一表面上,可為但不限於為下表面上,且該圖案20可為但不限於為RFID天線圖案,其係將內含催化成分之油墨印製於該基材10上後,再予以浸置於含金屬離子之溶液(圖未示)中,使金屬沈積於該基材10之該油墨上而形成者,其中該內含催化成分之油墨可為但不限於為環氧樹脂,該含金屬離子之溶液可為但不限於為氯化銅(CuCl2 )、硫酸銅(CuSO4 )、氯化鎳(NiCl2 )、硫酸鎳(NiSO4 )溶液,該金屬可為但不限於為金、銀、銅、鋁、鎳。
該黏膠層30係附著於該圖案20之另一未與該基材10接觸之表面上,可為但不限於為下表面上,其中該黏膠層30之黏性係大於該圖案20與該基材10間之黏性,且可被黏附於一貼附物40上,以形成一RFID標籤。其中,該黏膠層30可為但不限於為乾膠或不乾膠,其中該乾膠可為但不限於為強力膠、熱溶膠、AB膠或瞬間膠,該不乾膠可為但不限於為橡膠系膠或壓克力系膠;而該貼附物40則可為但不限於為玻璃、鋼板、磁磚、壓克力板、塑膠板或塑膠膜。
如圖3所示,當該RFID標籤被剝離該貼附物40時,因為該黏膠層30之黏性大於該圖案20與該基材10間之黏性,因此,該基材10即脫離該貼附物40,而該圖案20及黏膠層30則仍黏附於該貼附物40上,如此,即可防止該RFID標籤被重複使用,而達到防偽、防盜之目的。因此,本案之具防偽功能之RFID標籤結構確實較習知技術之RFID標籤結構具有進步性。
此外,本案亦揭露一種具防偽功能之RFID標籤之製造方法。請參照圖4,其繪示本案一較佳實施例之具防偽功能之RFID標籤之製造方法其流程示意圖。如圖4所示,本發明一較佳實施例之具防偽功能之RFID標籤之製造方法,其包括下列步驟:將一圖案20以內含催化成分之油墨印製於一基材10上(步驟1);經乾燥或烘乾後,該油墨與該基材10反應產生一第一附著力(步驟2);再將含有該油墨之該基材10浸置於含金屬離子之溶液中,使金屬沈積於該油墨上而形成具導電作用之圖案20(步驟3);最末在該圖案20上塗上一層具第二附著力之一黏膠層30,且該第二附著力大於該第一附著力(步驟4)。
於該步驟(1)中,將一圖案20圖案以內含催化成分之油墨印製於一基材10上;其中,該基材10可為但不限於為PET、PI、PVC薄膜,或PET、PI、PVC薄膜與貼紙之複合物,該內含催化成分之油墨則可為但不限於為環氧樹脂。
於該步驟(2)至(3)中,經乾燥或烘乾後,該油墨與該基材10反應產生一第一附著力,再將含有該油墨之該基材10浸置於含金屬離子之溶液中,使金屬沈積於該油墨上而形成具導電作用之圖案20;其中,該溶液可為但不限於為氯化銅(CuCl2 )、硫酸銅(CuSO4 )、氯化鎳(NiCl2 )、硫酸鎳(NiSO4 )溶液,該金屬可為但不限於為金、銀、銅、鋁、鎳。
於該步驟(4)中,在該圖案20上塗上一層具第二附著力之一黏膠層30,且該第二附著力大於該第一附著力;其中,該黏膠層30為乾膠或不乾膠,該乾膠可為但不限於為強力膠、熱溶膠、AB膠或瞬間膠,該不乾膠可為但不限於為橡膠系膠或壓克力系膠;而該貼附物40則可為但不限於為玻璃、鋼板、磁磚、壓克力板、塑膠板或塑膠膜。
因此,本發明之具防偽功能之RFID標籤結構及其製造方法,其係利用材質間附著力之差異,使已黏附在平整表面之RFID標籤經移除時,RFID標籤上之圖案因與基材間之附著力較低而脫離基材,以防止該RFID標籤被重複使用,而達到防偽、防盜之目的等優點。因此,本發明之具防偽功能之RFID標籤結構及其製造方法確實較習知技術具有進步性。
本案所揭示者,乃較佳實施例,舉凡源於本案技術思想之局部或均等變更或修飾,而為熟習該項技藝之人所易於推知者,俱不脫本案之專利範疇。
綜上所陳,本案無論就目的、手段與功效,在在顯示其迥異於習知之技術特徵,且其首先發明並合於實用,亦在在符合發明之專利要件,懇請 貴審查委員明察,並祈早日賜予專利,俾嘉惠社會,實感德便。
