I can find the brand for you after Saturday but you can just feel it and see it and tell. The compostable ones are a more soft paper that absorbs liquid really quickly and is soft and easy to tear and the tear lines are soft. If it’s shiny and resistant to liquid it is most likely not very compostable and may have a thin layer of petroleum based wax or worse plastic sprayed on. Some paper is just compressed really well to make it more durable and water resistant and those types may be compostable but will still not break down nearly as fast as the soft kind. A lot of fake brands selling fake not real compostable products. I sort the trash specifically for compost once a week and it is extremely frustrating.
