Ben,
I’m pretty sure that if it is completely encased with ‘shrink wrap’, that is a perfect picture of ‘encapsulation’. If the top of the pallet is left open but wrapped on the sides, then it would be non-encapsulated.

This is all based on the 2013 edition of NFPA 13. Section 5.6.3.1 gives you three criteria for how a noncombustible product is packaged. #3 says: Shrink-wrapped or paper-wrapped as a unit load with or without pallets. So my question is, does the shrink wrapping count as encapsulation, or can you ignore it since its already included in the base definition of a Class 1? For example: I have pre-made sheetmetal ductwork (no insulation) being put onto a pallet and then shrink-wrapped to keep water out. Is that just a class 1 commodity, or is it an encapsulated class 1 commodity? For my purposes, if its encapsulated my density goes up to 0.282 which exceeds my class 3 commodity in the same building!
