Among the four major pillars of packaging printing - paper, plastic, metal, and glass - the growth of paper is the fastest. Paper is the cheapest in price, has a wide range of raw material sources, and unlike plastic which is not easily soluble, or glass which is fragile, or metal which is heavy, paper is convenient to carry. Moreover, paper products are easy to decompose, they can be recycled into再生paper or used as plant fertilizer, and they can also reduce air pollution and purify the environment. In this regard, compared with plastic, metal, and glass packaging, paper packaging is considered one of the most promising green environmental protection packaging materials.
