Is the plastic film used in cigarette packaging biodegradable?

According to Article 11 of the Framework Convention on Tobacco Control regarding tobacco product packaging and labeling, there is no mandatory use of degradable materials. However, the current trend of using this material in European and American countries may not necessarily be used in our country. It is not mentioned in the key points of scientific and technological work of the State Tobacco Monopoly Administration. As for the shrink film bundle materials used for cigarette outer packaging, there are many patents.

If the country does not force the use of degradable materials, which cigarette factory will take the initiative to produce them?
