Polynet, a low-density polyethylene, protects against damage to exterior surfaces of machined, polished, plated, coated, and threaded areas, especially during shipping.
It doesn't retain moisture and is said to be easy to apply and remove. Polynet is most commonly used during and after costly in-house machining or processing to protect value-added features during shipment. It is available in rolls or can be cut to size. There are also light and heavy-weight versions and can be color coded to help distinguish dimensional sizes.
