The Micro Gravure™ coater is a relatively new specialized coating technique that has found extensive use in the manufacturing of low coating weights on light gage films. It is used to coat a variety of products, for imaging, electronics, packaging, coated thin film batteries, and other specialty applications. This method can achieve a coating weight uniformity, of +/-2% at the low coating weights and the high quality levels required for these products. The majority of the standard coating methods cannot achieve the uniformity and quality required for these products. (...) Read More...

The Test & Toll Coating Service Division at Yasui Seiki’s subsidiary, MIRWEC Film Inc, in Bloomington, Indiana, has been experiencing unprecedented growth since the end of 2013 due to rising demands in manufacturing thin battery components. Yasui Seiki has installed five coating machines with its patented MICROGRAVURE™ coating method, as well as a variety of slot dies, at MIRWEC. Recently the company has been supporting customers in anode/cathode coating as well as battery separator coatings. MICROGRAVURE™ can easily, quickly and evenly apply less than 3 microns of a variety of slurry and other coatings onto substrates with less than 2% variation. The web thickness that has been successfully handled has been as thin as 8 microns.
Consumer demand is increasing so much that Yasui Seiki’s existing coating lines can no longer handle all requests. The company has a plan in place to build a brand new 700mm-wide coating machine exclusively for battery coating customers. The door to the new coating room is scheduled to open in early 2016. The MICROGRAVURE™ coating method has had a very solid client base in Japan for over 30 years, and Yasui Seiki has been very excited to see the growth in the USA in recent years.

[Summary] Yasui Seiki Japan developed non-silicone laminated film. The film consists of three layers: a release layer (99.99% pure polypropylene), an adhesive layer, and PET. Eliminating all additives from the polypropylene to protect its purity is the key to easy release. The heat tolerance has been improved from the PP's normal 80 deg. C to 120 deg. C. The surface texture can be glossy or mat. Yasui Seiki is working closely with the customers to increase the effectiveness of the film and is getting ready to launch it on the market.
Yasui Seiki's subsidiary, Labo, Co., Ltd. handled the research and development. Yasui Seiki will purchase PP film for high voltage capacitors from the US subsidiary, MIRWEC Film. In addition to the main application as the non-silicone release film, the new film has a wide range of possibilities. It could replace PET use in wrapping, post-mold decoration, sandmat process, etc.
