You don't know the common sense of washing powder bags.
The development of laundry detergent bags has gone through a simple to complex process, from 1-2 color PE printing bags in the 70s and 80s to 1-6 color composite printing bags in the 1990s. Newly produced materials such as PVDC, PT, and vacuum-aluminized film (VM) have also been researched and used, and the detergent packaging bags are moving toward more practical and aesthetics.
Most of the materials used in laundry detergent bags are made from PP, PE, OPP, and BOPP plastic materials. Generally, households rarely recycle them, and only throw them away when they are waste or garbage. For packaging materials, some large companies have done some research, but the effect is not very satisfactory. They use paper instead of plastic film, because the washing powder is easy to absorb moisture, agglomeration and other factors, the cost of adding paper is high, it is not easy to seal, etc. This caused the new thing to die.
With the continuous development of the printing industry and the continuous advancement of technology, good inks will replace low-quality and low-cost inks. Edible and environmentally friendly laundry detergent bags will become mainstream.
