[0002] Plastic packaging bags are packaging bags made of plastic as raw material, used in the production and daily life of various products. They are widely used in daily life and industrial production. However, this convenience brings long-term harm. Most commonly used plastic packaging bags are made of polyethylene film, which is non-toxic and can therefore be used to hold food. Another type of film is made of polyvinyl chloride (PVC). PVC itself is also non-toxic, but the additives added to the film depending on its intended use are often substances that are harmful to the human body and have a certain degree of toxicity. Therefore, this type of film and the plastic bags made from it are not suitable for holding food.
