4. Main secondary packaging

Those concerning food liquids are :

• packing cartons ;

• PACKAGES ;

• bottle racks ;

• plastic film bundles.

They require the use of materials that are not specially food-grade, but are specific to the conditions in which they are to be used.

Secondary packaging is handled on free or motorized roller conveyors, belt conveyors and, in some cases, pallet chain conveyors.
