Polyethylene Comments
POLYETHYLENE BAGS: Used for Packing Orchids Dry out the plants first (superficially) pack fairly tighly in polyethylene bags and place a 1/2 teaspoon to 1 tablespoon of malathion powder with each plant; tumble it about then press out the air; pack them well in a light box for air shipment. OD78-165 0
POLYETHYLENE FILM: As Greenhouse Insulation Liner Use the regular type rather than the ultraviolet resistant type because the former is adequate; greenhouse glass filters out rays shorter than 312 millicrons. A68-911 0
POLYETHYLENE FILM: Inside Insulation 6 mil. will not block out too much light if kept clean. A77-995 0
