Compared with fossil-based plastic bags, what are the unique features of renewable plastic bags? How to define recyclable plastic bags and degradable plastic bags? What is the difference between degradable plastic bags, renewable plastic bags and recyclable plastic bags? Today, the professional flexible packaging manufacturer Chuangyi Union packaging will provide you with a science popularization article, one by one to interpret these hot environmental protection words.
Plastic bags from renewable materials VS plastic bags from fossil based materials
To figure out what is a renewable material plastic bag, you first need to understand what is a renewable resource. Renewable resources refer to the resources that can multiply and grow, continuously regenerate to keep up with the rate of consumption, and continuously maintain or expand their reserves and can be reused by human beings under the specific time and space conditions of nature. Forests, soils, grasslands, wetlands, solar energy, wind energy, water energy, animals, plants, microorganisms, and various natural biomes are all renewable resources.
Renewable plastic bags are plastic bags made of materials produced by such renewable resources. Typically, such materials can be made or produced quickly, or replaced or supplemented by biological and other natural processes to keep pace with their use. Wood, cardboard, paper and pulp are all widely used renewable materials. As long as through effective sustainable forestry management, a continuous supply of wood can be achieved to support the normal functioning of human society.
Fossil-based plastic bags refer to those made of materials from the earth's limited fossil resources. Oil, natural gas, coal, mineral deposits or organic fossil deposits are all fossil resources, which are not renewable in the short term. Production materials that rely on the processing of such resources, such as glass, plastics, metals, etc., are fossil-based materials.
Recyclable plastic bags, recyclable plastic bags, as the name suggests, refers to plastic bags made of materials that have recyclable value and can be recycled after recycling. Common recyclable materials in life include paper, cardboard, glass, plastic, metal and so on. Among them, paper and cardboard take into account the dual characteristics of renewable and recyclable materials.
Recyclable materials play a huge role in energy conservation and environmental protection. Data show: a ton of waste paper can produce 850 kilograms of recycled paper, saving 3 cubic meters of wood; Discarded PET plastic bottles can also be recycled into yarn and used as fabric materials in furniture, automotive and other industries.
Degradable plastic bags, in the recycling link, there are two common concepts: biodegradable and compostable.
In recycling, there are two other common concepts: biodegradable and compostable.
Compostable is a higher standard than biodegradable: the efficiency of biodegradation is improved by controlling humidity, temperature, and oxidation processes, and requires that substances are ultimately broken down into completely non-toxic components. The whole process is environmentally friendly. It can be seen that compostable plastic bags must be biodegradable, but biodegradable plastic bags may not be compostable.
Most industrial waste, including traditional plastic bags, takes a long time to decompose under natural conditions, and some take hundreds or even thousands of years, causing great harm to the environment. Wood and paper are typical biodegradable plastic bag materials, compared to traditional plastic bags, their impact on the environment is obviously more friendly.
According to incomplete statistics, the country sends out more than 10 million copies every day, of which a large number of plastic packaging products are used. Considering that it takes at least 400 years for a traditional plastic bag to degrade, more and more consumers are calling for renewable and biodegradable plastic bags to replace traditional plastic bags.
