4223 was developed for the permanent sealing of polythene and polypropylene bags, where a higher bond performance than is achievable with 4123 is required. It is supported by a hot wire/knife cuttable film release liner offering increased manufacturing speeds. Care should be taken with very low gauge LDPE/HDPE bags regarding ease of liner removal.
