Anyone who has handled a few rounds of online orders knows that poly mailers don’t have an easy journey. They get dragged across belts, thrown onto stacks, squeezed between boxes and sometimes land in weather that wasn’t part of the plan. At Aly Packaging UK, our custom poly mailers are built with the real conditions that are most likely to occur. Our aim is not to manufacture mailers that offer the best appeal but those that fulfill utility of clients. The ones couriers don’t advertise but every sender has seen at least once.
