This is a custom packaging for bottles in the form of Kraft tube packaging. The raw material of the paper tube is completely made of kraft paper, so that the inner and outer sides of the paper tube are visually completely brown, giving people a concept of environmental protection. Normally, the inner size of the paper tube is 3-5mm more than the product. The size of the 500ml bottle is 75mm in diameter and 270mm in height, so the inner diameter of the paper tube is 78mm and the inner height is 275mm. There are a total of 7 different styles of bottles, and customers can directly determine the type of the bottle through the different bottle patterns on the paper tube. Printing specific product information and simple slogans on the paper tube is also very helpful for customers to understand and purchase products.
