Yes, they can be thrown directly into the trash can, but you need to sort them according to their type.
1. Material properties determine classification: OPP bags are made of polypropylene plastic (the main recyclable material), but the actual disposal depends on their condition. If the bag is clean and uncontaminated (e.g., packaging new clothes, unstained oil), it is recyclable waste; if it is stained with oil, food residue, etc., and cannot be cleaned, it should be classified as other waste.
2. Regional classification rules: Some cities have stricter requirements for trash cans. For example, Shanghai allows direct recycling of single-material plastics, while Beijing may prioritize other waste disposal due to differences in end-of-life processing capacity. It is recommended to check local regulations through community announcements or official mini-programs.
For example, OPP bags used for packaging frozen food in supermarkets often have water residue inside after thawing. If these bags cannot be thoroughly cleaned, directly throwing them into the recycling bin may affect sorting efficiency due to impurities; classifying them as other waste is safer. Other common applications such as clothing packaging and inner bags for express delivery can be directly recycled if they are not dirty, promoting resource reuse.
