What does closed cell mean for this foam?

The cells are sealed, so the foam does not soak up water like open-cell foam. That makes it better for outdoor, damp or sealing uses.

How does 2 lb density compare with denser PE foam?

It is lighter and softer than 4 lb or 6 lb PE foam. It cushions well for light to medium loads but compresses more under heavy weight.

Yes. Closed-cell PE foam cuts cleanly with a sharp utility knife or hot wire. A straight edge helps for long cuts.

It is rated from -110 to 212°F, so it holds up in freezers and hot environments where other foams soften or crack.

It works for light and medium items. For heavy or sharp objects, a denser sheet gives more impact protection.
