Plastic bags and plastic films are one of the most "bad" waste materials in the waste recycling industry. For example: bubble bags, packaging materials, zipper bags, garbage bags, tarps, cling film, cereal box liners, shopping bags, porous plastic file covers containing newspapers, etc.
The reason why these materials are "not good" is that they have a problem that they cannot be decomposed by organisms. They are broken down into small particles by light. Small particles will pollute the soil and water, and it is difficult and expensive to dispose of.
It is estimated that in the process of incineration and landfill, recycling of plastic bags and plastic films can create six to ten times more jobs.
The recycling of these materials creates a need for compression balers, because if compression and baling are not carried out, these waste materials are not convenient to transport.
