The PL304WH is a 4 gallon white HDPE plastic square pail lid with tear-tab (no gasket). This is a heavy-duty pail lid and is ideal for industrial, heavy-duty applications. When fastened to a pail, these filled pails can be stacked on top of each other to optimize storage space. This lid has been equipped with a tear-tab tamper-evident mechanism. Once the lid has been initially fastened to the pail, it cannot be removed without removing the tear-tab. High density polyethylene (HDPE) is marked with the resin identification code of 2. HDPE has a high tensile strength, good resistance to chemicals, good impact resistance, highly rigid, and highly scratch resistant.
