Sourcing tips
Confirm film thickness in microns (standard 50–60 microns): co-extruded multi-layer opaque poly blocks interior item visibility.
Courier mailers take substantial shipping volume: request suppliers to compress bundles tightly into export cartons.
At our warehouse, staff inspect side weld tear resistance and verify that the permanent hot-melt adhesive tears the bag on opening.
