paddedenvelope - shipping packing materials

Packaging Supplies Company''s boxes are "200 lb burst test" paddedenvelope certified. (We do carry some "275lb burst test" paddedenvelope certified boxes too.) This means that the corrugated walls of the box would require paddedenvelope 200 pounds per square inch of force to break through the wall of the box. The burst test has been a standard certification for years. More recently a new certification test has started to be used called the Edge Crush Test (ECT). Generally, 200lb test boxes are 32 ECT. ECT is the edgewise-compressive strength, parallel to the flutes of a short column of corrugated fibreboard. Test results are reported as the pounds per inch required causing compression failure. ECT relates directly to box compression strength which is important in today''s world of box stacking.

Metallocene film is a new hybrid stretch wrap that offers up to twice the tear and puncture resistance of conventionally manufactured films. Metallocene resins are cleaner, stronger, and tougher than conventional resins like octene, hexene, and butene. Metallocene film is available in rolls that require a hand dispenser. Packaging Supplies Company stocks metallocene film that is 16" wide and ranges from 14-19 microns. Gauge Chart The thickness (and therefore strength) of stretch wrap is measured in gauge or microns. A larger number means more thickness and more strength. Refer to the chart below for comparisons with other common measurements.
