Packaging inserts for products made by an air-laid web process that uses natural fibers and a thermoplastic binder. The process involves generating imprints in the unbonded web, heating it to partially melt the binder and bind the fibers, then cutting the bonded web into inserts with the imprints retained. This allows customized cavities for product fitting without extra processing steps. The imprints conserve shape due to fiber elasticity. The binder can be monocomponent thermoplastic fibers or powder. The air-permeable web is captured on a conveyor and compacted by vacuum.
