What are the precautions for label use in winter?
不干胶标签材料是20世纪30年代由美国人R.斯坦顿.艾利发明的。开始使用手工制作,后来,艾利先生发明了第一台涂布机和标签生产设备并开始机械化生产。
不干胶材料是对传统标签材料的巨大挑战,是标签领域内的一场革命。自30年代后,不干胶材料技术迅速传播 到世界各地。一些国家纷纷建厂,研究和开发了各种各样、不同种类的标签材料。 不干胶材料的发展史也是本世纪科学技术的发展史,目前,国际上不干胶材料的基本现状是: 1、面料。以纸张类为主并向多种材料、特种用途发展,如 合成材料、防伪材料和转移材料等。 2、粘合剂。由对环境有污染的溶剂型、热熔型粘合剂向对环境无污染的水溶型乳剂粘合剂发展。 3、涂布技术。有多种涂布方法,目前的发展方向是由传统的辊式涂布、刮刀涂布向高压流延涂布发展,以最大限度的保证涂布的均匀性,避免气泡和针眼的产生、保证涂布质量。
The material of non-drying label was discovered by R• Stan Avery, an American, in the thirties of 20th century. The label was made by hand firstly, and later, Mr. Avery discovered the first coating machine and label production equipment, and began the mechanized production.
The non-drying adhesive material is a titanic challenge for traditional label material, which is a revolution in label field. Since the thirties of 20th century, the technology of non-drying adhesive material began to spread all over the world. Some countries followed to build factories, research and develop kinds of label materials. The development history of non-drying adhesive material is also that of scientific technology in this century. At present, the basic current status of non-drying adhesive material in the world is as follows:
1. Fabric It mainly focuses on paper and develops various materials and special uses, such as synthetic material, anti-counterfeiting material and transfer material, etc.
2. Adhesive It develops from the solvent-type and hot melt adhesive, which pollutes environment, to the environmental-friendly water-borne emulsion.
3. Coating technology There are many coating methods, and at the present, it aims to develop from the traditional roll coating and blade coating to the high-pressure cast coating, which maximally ensures the coating evenness, avoids bladder and pinprick, and guarantees the coating quality.
