LDPE is overwhelmingly a film business: shrink hood, agricultural sheet, heavy-duty liner, bread bag, and the extrusion coating grades that go onto board and foil. Prime lots are bought on melt flow and density in the usual way, with most film grades sitting between roughly 0.3 and 2 g/10min, and the additive package — slip, antiblock, UV — mattering as much as the base resin for how the film behaves on a line.

The reprocessed side of the market has its own vocabulary, and it is worth using it precisely. Natural film scrap is graded on how much colour is tolerated in the bale, which is what a 95/5 or 90/10 offer is describing, and clear natural commands a premium over mixed colour for the obvious reason. Beyond that, the questions are moisture, whether agricultural film has been washed free of soil and silage residue, and whether printed film has been kept out of a natural stream — ink is a colour contaminant like any other.
