The raw material for a high quality baking box is of course paper. Modern paper may come from trees or recycled paper products. If you use the pulp, of course you need to cut down the trees, and the environmental impact needs to be added to the paper bag, it's not so clean. If it is to use recycled paper, of course, less of the crime of cutting down trees, but waste paper recycling, cleaning, deinking, re-pulping process will actually produce a lot of dust and sewage, and need to consume more energy. And, recycled paper because of the short fiber, bearing capacity is a little poor, domestic use it to do paper bags or less, more or made of printing paper. In other words, most of the paper bags you use are probably made of raw pulp.
The raw material of producing plastic bags is ethylene which is fractionated from petroleum. The polymerization process of ethylene is a mature process. If only from the point of view of energy consumption and pollution in the production process, the production of polyethylene plastic bags is more environmentally friendly than the production of paper bags. Plastic bags but the bigger question is buried in the ground a few hundred years can degrade, most neglected waste management in our country, also is light, let people have a more intuitive understanding of pollution to the environment comprehensive analysis of the production process and disposal after use, plastic bag or paper bags have no small impact on the environment, is not to say that bag is a sign of environmental protection and fashion.
So what is green? Break away from the formulaic slogans. If you use plastic or paper bags, use them as many times as possible to keep them in the world. Or, still use cloth bag, after all, cloth bag is used hundreds of times do not have a problem, dirty it is good to wash, still can write on above draw the thing that makes some of have character, enough vogue, even if cloth bag also has environmental cost, use it so hundreds of times, also calculate earn quite this.
