With the concept of low-carbon environmental protection becoming the main theme of society, low-carbon environmental protection is being implemented in many fields, as is the field of packaging materials. Many packaging materials that pollute the environment are fading out of our life. Green packaging materials have become the development trend and future of the packaging industry.
At present, there are many kinds of green packaging materials, which can be divided into reusable and recycled packaging materials, edible packaging materials, degradable materials and paper materials. Reusable packaging materials mainly refer to the glass bottle packaging used to package beer, beverage and so on, which can be used repeatedly for many times.
Recycled packaging materials mainly refer to plastic packaging materials, which can be made into recycled packaging containers after being disposed of by physical methods. After chemical treatment, it can be made into recycled packaging products. However, the drawback of these two methods is that they only reduce the pollution to the environment. In the final treatment, they have to face the problem of polluting the environment.
