A flexible container liner, preferably for use in containers capable of dissipating electrostatic charges, with at least one liner wall which includes a single layer or multilayer wall material, preferably of polymers, such as LDPE monofilm, a co-extruded polymer film or the like, the liner wall having a layer which is electrically non-conductive, in order to meet high requirements with respect to the non-chargeability of the container and with regard to very good barrier properties against the passage of gases, is so constructed that either at least one layer of the liner wall has microrecesses extending at least over a portion of its thickness or microprotrusions, which have material of reduced thickness in their front region lying parallel to the layer, are disposed in at least one layer of the liner wall.
A flexible container, comprising:
A flexible container, comprising:
A flexible container liner, comprising at least one liner wall which includes at least one layer, said at least one layer including at least one non-conductive layer, at least one of said at least one layer having microrecesses extending over only a portion of the thickness thereof, an electric breakdown voltage measured over a whole of the liner wall not exceeding 4 kV.
A flexible container liner, comprising at least one liner wall which includes at least one layer, said at least one layer including at least one electrically non-conductive layer, at least one of said at least one layer having microprotrusions which have at least portions of reduced thickness in front regions thereof lying parallel to a remainder of the at least one of said at least one layer, an electric breakdown voltage measured over a whole of the liner wall not exceeding 4 kV.
A method of inhibiting development of a static charge in a flexible container for bulk goods while concomitantly providing a barrier against outward passage of stored product, the flexible container including conductive structures for dissipating electrostatic charges transferred thereto from the stored product, the method comprising:
