// Why Buy From The Bag Broker
Sealers, closures and spares sit in the same Melbourne warehouse as the bags they are used with — one order, one delivery, and a team that can tell you which one fits your packaging.
Held locally, not shipped from overseas to order — so there is no long wait for a machine or a part.
Order online before the daily cut-off and it leaves the warehouse the next working day, with the bags on the same order.
Compatibility with our box bottom, side gusset, stand up and flat pouches is stated on every product — check the seal width against your bag.
Not sure which sealer or spare fits? Ask before you order — we have supplied flexible packaging since 2004.
