Since the Swedish packaging designer Steen Gustaf Turin designed plastic bags in 1959, plastic bags have been around for 61 years. Plastic bags have promoted the development of human society. Now most of the things around us They are all plastic products, but plastics have become the world's biggest environmental pollution problem.
In order to treat these white pollution, scientists in many countries are looking for products that can replace plastic bags and reduce environmental pollution. Later, many kinds of degradation bags appeared on the Internet. There are degradable plastic bags, microbial degradation bags, etc. So what exactly is a degradation bag that can really contribute to environmental protection?
Degradable plastic bag: It is a plastic bag mainly made of polyethylene plastic, mixed with mineral powders such as photodegradants and calcium carbonate, also called photodegradable plastic bags. This plastic bag is decomposed under the action of sunlight. However, the decomposed polyethylene still exists in the natural environment. Although the white pollution is not visible in the line of sight, the white pollution is still injuring our surrounding environment in the form of fine particles.
Microbiologically degradable bag: a plastic bag made of polyethylene plastic as the main ingredient and blended with starch and other biodegradants, also called biodegradable plastic bag. This kind of plastic bag is decomposed mainly by the action of microorganisms, and the effect is the same as that of the photodegradable plastic bag.
I hope everyone can start from the individual and reduce white pollution.
