In order to reduce its cost, in recent years, most companies have joined about 30% of calcium carbonate filled with plastic shopping bags, such plastic shopping bags in the garbage dump when the release of toxic gases.

Paper shopping bags

We all know that the paper strength and water resistance are not good, a lot of water-based products such as seafood can not packaging, heavier metal products are difficult to load. Even if we all switch to paper bags, and that paper is how to it?

First, the raw materials for the production of paper mainly wood, the world's forest resources is extremely scarce, which is the greatest waste of environmental resources; followed by the process of making paper will produce a lot of water pollution, paper mills across the country, such as crossing mice, beaten everywhere. Therefore, a large number of paper bags is the largest waste of environmental resources, the largest environmental pollution.

Such as we are known as environmentally friendly shopping bags of ordinary non-woven shopping bags, polypropylene fiber is made with a special process, in essence, polypropylene (PP) for the typical varieties of plastic, also belong to the plastic bag, so environmental And ordinary plastic shopping bags, also can not be completely degraded. From the specific cost-effective speaking, under the same conditions, the strength of non-woven bags as plastic bags, and not waterproof, the price is higher than the plastic bags as much as several times. More need to mention is the use of more than two kinds of materials made of non-woven shopping bags, recycling more difficult than ordinary plastic shopping bags.

Cotton and linen shopping bags

Cotton and linen shopping bag strength is better than paper bags, can be recycled several times, but the water resistance is not good. The advantages of cotton and linen shopping bags can be recycled, but the bag dirty how to do? Water washing is the most commonly used method, but the water is wasted water resources, with phosphorus-containing detergent will pollute the soil, while ordinary washing and can not kill bacteria.
