Press seal bags are the everyday resealable bag you reach for a hundred times a day — a simple interlocking plastic seal you press closed with your fingers, no heat or tape needed. Also called zip lock or zip seal bags, our press seal bags are made from clear 50 micron LDPE and come in a big spread of sizes, sold by the box.

How press seal bags work

The two sides of the opening have matching ribs that click together when pressed and pull apart when you need the bag open again. That means you can reseal the same bag over and over — ideal for small parts, samples, food, jewellery and documents.
