压敏胶的粘性测试,主要分为:初粘性测试、持粘性测试(同时持粘性测试,又叫做保持力测试)、剥离力测试。
初粘性测试遵循的标准为:GB/T 4852-2002|压敏胶粘带初粘性试验方法(滚球法)、JIS Z0237 ;
持粘性测试遵循的标准为:GB/T 4851-1998|压敏胶粘带持粘性试验方法、 JIS Z0237、ASTM D3654
压敏胶剥离力遵循的标准为:GB/T 4850-2002压敏胶粘带低速解卷强度的测定
另外world不干胶标签协会(FINAT)有一套独立的测试标准。FINAT是一家国际贸易协会,致力于推动自黏标签的发展,FINAT官方网站:http://www.finat.com 。网站上有相关的技术手册,下为目录,如果您需要,可以到官方网站购买相应的技术手册,应该有中文版的手册。
