According to the Environmental Protection Department's inspection and approval of the following licenses, it is confirmed that the sewage generated from the production process does not cause damage to the environment and grant the relevant discharge authorization. Again, this prove that our production is highly eco-friendly. To protect the Earth, we insist to use fully biodegradable flexo (a kind of mold for printing) from Japan and use the water-based ink from UK. The material cost is much expensive than the traditional material but we counterbalance the cost by increasing our productivity and efficiency.
