How does polyethylene handle exposure to tree sap?
Polyethylene, a widely used plastic, exhibits strong resistance to tree sap due to its non-polar molecular structure, which repels water-based and organic substances. While short-term exposure typically causes no significant damage, prolonged contact may lead to surface discoloration or minor swelling in some cases. High-density polyethylene (HDPE) performs better than low-density variants against sap's natural acids and sugars. For outdoor applications where tree sap exposure is likely, polyethylene remains a durable choice, though regular cleaning helps maintain optimal performance. Industrial-grade polyethylene formulations offer enhanced protection against organic compounds found in tree sap.
