Good afternoon,
In general polypropylene (PP, #5 plastic) is considered safe for organic gardening, as it is non-toxic, chemically inert, and does not leach harmful substances into the soil. It is commonly used for durable, UV-resistant plant pots, seed trays, and fabric grow bags.
However, if you want to avoid plastics, you can us an alternative such as cardboard to help suppress weeds.
