In the current international situation of saving energy and preventing environmental pollution, pollution-free and pollution-free “green packaging†is quietly rising in the world.
The so-called green packaging has not yet seen a complete definition. Generally has four connotations, namely: the most provincial materials, the least waste, and save resources and energy; easy recycling and recycling; waste combustion produces new energy without secondary pollution; packaging materials and self-decomposition , does not pollute the environment. Therefore, the goal of packaging is to preserve the maximum natural resources, to form the minimum amount of waste and minimal environmental pollution.
The four pillars of modern packaging - paper, plastic, metal, glass. Among these four kinds of packaging materials, paper products have the fastest growth, paper and plastic are the cheapest, and raw materials are widely available. Therefore, paper and plastic packaging are widely used in daily life. According to international health organizations and domestic environmental protection experts, plastic waste may cause white pollution and is not conducive to environmental protection. Therefore, the use of plastic food bags should be gradually banned and regulations must be made in environmentally friendly paper bags. This year's shopping uses non-toxic, harmless "full paper eco-bags." Paper products are prone to decay and can either recycle recycled paper or make vegetable fertilizers, reduce air pollution, and purify the environment. Therefore, paper packaging and plastic, metal, glass and other three major packaging compared, and LCA technology for quantitative evaluation, paper packaging will become one of the most promising green packaging materials.
