The most stringent "ban on plastic" is fully promoted, and the demand for new environmental protection materials is released at a faster pace
Perhaps many people do not know that their usual disposable paper cups, seemingly very environmentally friendly, but in the garbage classification is not recyclable category. Paper can not cover fire, also can not cover water, in order to achieve the barrier of water and oil, paper cup often need to add a layer of plastic film (film) on the base paper, the vast majority of the current market for polyethylene (PE) film. However, PE coating products are non-degradable, non-repulpable and difficult to recycle, so they are classified as non-recyclable waste.
Previously, disposable paper cups mainly comply with GB/T 27590-2011 "paper cup" standard, but this standard does not include coated paper cups, technical indicators can not meet the needs of coated paper cups. "Plastic Free Paper Cup (including Plastic Free paper Cup paper)" group standard solicit draft further proposed that "paper cup base paper should meet the requirements of QB/T 4032. White oil shall comply with GB 1886.215. Inks and adhesives should meet relevant standards. Additives used in paper cup base paper, white oil, ink, adhesives and water-based coatings shall meet the requirements of GB 9685."
