Express bags are also a kind of plastic packaging bags. The general express bags need to consider people's color thoughts when planning the color.
First, a sense of warmth
Supply bags produced in summer use cold colors to give people a cool feeling, while bags produced in winter use warm colors to give people a sense of warmth.

The lightness and darkness of the colors, the warm and cold, the obvious confusion, and the contrast will give people a different distance to understand.

Different colors will give people different tastes, but you can choose different color packaging materials for the taste of food.
