What are the differences between PS and PVC seedling trays?
PS seedling trays are made of polystyrene (PS), while PVC seedling trays are made of polyvinyl chloride (PVC). Currently, most seedling trays on the market are made from recycled materials. PS seedling trays are more expensive than PVC seedling trays. PS seedling trays are more stable, heat-resistant, and have a longer service life. PS seedling trays are environmentally friendly and recyclable, containing no harmful substances, odorless, and pollution-free. They are also antioxidant, waterproof, moisture-proof, mildew-proof, insect-proof, effectively flame-retardant, and durable. Conversely, PVC seedling trays are less stable and have poorer heat resistance, especially under light conditions, making them prone to decomposition and thus having a shorter service life. Furthermore, PVC decomposition produces small amounts of chlorine gas, polluting the environment and posing a health risk. Therefore, PS sheet material is generally recommended for seedling trays.
