Packaging Design Danquan 168 Cave Aging Premium Liquor by Chuangyi Packaging Design Co., Ltd. in Chengdu Danquan 168 is a packaging design for a premium sauce flavoured Baijiu produced in Nandan, Guangxi. The bottle is made of high borosilicate glass with a titanium plated surface, shaped by 3D embossing and laser engraving with a precision of 0.1 millimetres. The engraved textures recall the sedimentary formations of limestone caves and refract light when the bottle is turned. The outer box uses a layered structure that abstracts the local cave landscape. The packaging measures 180 by 108 by 290 millimetres and links the regional cave ageing tradition to the product.
