Does the environmental protection index of cigarette package uv varnish meet the industry requirements?
Release Time : 2024-12-04
The environmental protection index of cigarette package uv varnish meets the industry requirements to a large extent, but there are also some key points that need attention.
From the perspective of volatile content, the industry has strict requirements on the residual solvent content of cigarette package uv varnish, which is generally required to be less than 0.5% to reduce the emission of volatile organic compounds (VOC) and avoid harm to the environment and human health. Many cigarette package UV varnishes produced by regular manufacturers can meet this standard, such as the "Baihemei" brand water-based varnish produced by Guangzhou Baihe Chemical Co., Ltd., which has no irritating odor, meets high standards of environmental protection, passes SGS testing, and meets export standards to Europe and the United States.
In the selection of photoinitiators, some high-performance cigarette package UV varnishes use tmo (2,4,6-trimethylbenzoyl) di (p-tolyl) phosphine oxide, 2- (4-methylbenzyl) -2- (dimethylamino) -1- (4-morpholinylphenyl) -1-butanone, polymerized benzophenone derivative type 2 photoinitiator, etc., to achieve odorless and environmentally friendly zero VOC emissions, in line with the latest VOC standards of the cigarette packaging industry and EU EN71 Part3, RoHS and other standards.
However, there are also some poor quality UV varnishes on the market. In order to reduce costs, some suppliers may add a large amount of solvents, such as alcohol and toluene, which will lead to excessive volatile content, which will not only have a pungent smell, but also pollute the environment.
In addition, the selection of raw materials for cigarette package uv varnish is also related to environmental protection indicators. If improper chemicals are used, it may cause residual odors to be difficult to dissipate after construction, affecting the quality and safety of cigarette packages.
In general, cigarette package uv varnish produced by regular manufacturers usually meets industry requirements in terms of environmental protection indicators, but when selecting and using it, it is still necessary to strictly control the quality, pay attention to its volatile content, the type of photoinitiator, and the environmental protection of raw materials, etc., to ensure the environmental protection and safety of cigarette packages during production and use.
