More and more countries have begun to restrict the use of plastic bags and promote degradable packaging bags. There are many types of degradable materials on the market, and the most well-known one is PLA, which is a material based on corn or sugarcane. After certain composting conditions, it can be degraded into corn or sugarcane. This material can indeed be 100% degraded and recycled. However, this material has two major limitations. First, the composting environment is very restrictive, which is difficult to reach in ordinary places. The second is the most important point. The material can only be degraded when used alone and cannot be used as a composite packaging material. We know that food packaging bags are composited with PET, OPP, PE and other films, and when PLA composited with these materials,it cannot help the degradation of these materials, PLA can only be partially degraded, and other composite materials are still non-degradable.
1, First, we can make single layer biodegradable packaging, like below the shopping and garbage packaging.
2, Second, We currently use reverte masterbatch in BOPP and PE, and the zipper can also be made degradable. The report is avaliable.
3, Third, biodegradable paper packaging is the most popular one. Cos no matter what kind of plastic bag you use, people wont treat them as biodegradable packaging, but paper packaging is different, paper bag itself is treated as biodegradable one. Like below the white paper bag, you can see, its just made of 2 layers, paper+PE, we directly print on the white paper, this way, we save one more plastic layer, which make it more like a biodegradable bag. Thne we use biodegradable PE instead of common PE, then the bag can be totally biodegradable. Just one thing about printing, left white paper bag, we directly print on the paper, right brown paper bag, we print on the outside layer BOPP, if you compare carefully, you will find the printing on the right brown bag is clearer than left white one.
