As a widely used item in life and business, plastic bags can be seen almost everywhere. With the improvement of living standards and the deepening of environmental protection concepts, the society has higher and higher requirements for plastic bags. Degradable plastic bags are more popular and praised. This is also the mainstream of the future society and the development direction of plastic bag manufacturers.
This environmentally friendly and degradable plastic bag is different from ordinary plastic bags in terms of technology and materials.
We can divide them into four categories:
1. Photodegradable plastics: under sunlight, they can be gradually decomposed by adding photosensitizers into the plastic bags. This method of making plastic bags belongs to the early technology, and the application is relatively successful, but its disadvantage is that it is difficult to control the plastic according to the sunshine and climate. The decomposition time of the bag.
2. Biodegradable plastic bags: can be naturally eliminated under microbial decomposition. This plastic bag has a wide range of applications and is especially popular in the medical/pharmaceutical industry.
3. Water-degradable plastic bags: After adding water-absorbing substances, the material of the plastic bag changes, and it can be dissolved in water after use. These plastic bags are mainly used in the medical/pharmaceutical industry for easy disinfection and destruction
4. Plastic bags that combine photodegradation and biodegradation: Environmentally friendly plastic bags are produced by combining these two plastic bag manufacturing technologies. No more usage than regular plastic bags. Ordinary plastic products take hundreds of years to completely decompose in the natural environment, causing great harm to the environment. Therefore, the development of environmentally friendly plastic bags requires people’s strong support, and every plastic bag factory must respond positively!
