Foreword

For the implementation of the "People's Republic of China Environmental Protection Law" to reduce offset printing ink in the production and use of the environment and human health Ring, protect the environment, the development of this standard. This standard on offset printing ink production process, the product of toxic and hazardous substances limited and packaging and description of the requirements. This standard has revised the technical requirements for "environmental labeling products" (HJ/T 370-2007). The main changes are as follows. - Adjusted scope, terms and definitions; - Increased restrictions on hazardous substances in the production process; - Adjusted the limited requirements of hazardous substances in the product; - Added packaging and description requirements. This standard is organized by the Ministry of Environmental Protection Science and Technology Standards Division. The main drafting of this standard. Environmental Development Department of Environmental Protection, China Daily Chemical Industry Association of ink, Beijing Green Business Development Center, Hanghua Ink and Chemical Co., Ltd., Tianjin Toyo Ink Co., Ltd., Xinxiang City, Germany and Germany Cheung Chuan Ink Co., Ltd., Suzhou Koswood Ink Co., Ltd. This standard is approved by the Ministry of Environmental Protection on October 17,.2016. This standard has been implemented since January 1,.2017, and is replaced by HJ/T 370-2007 since the date of implementation. This standard is explained by the Ministry of Environmental Protection. This standard replaced the previous version of the standard release. - HJ/T 370-2007. Environmental labeling products Technical requirements Offset printing ink
