Packaging Supplies Company''s boxes are "200 lb burst test" certified. (We do carry some "275lb burst test" certified boxes too.) This means that the corrugated walls of the box would require 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.

Packaging Tips Select a box that is strong enough to protect the contents. Leave space for cushioning inside the carton. Cushion package contents with shredded or rolled newspaper, bubble wrap, or Styrofoam peanuts. Plain air-popped popcorn is also good for cushioning; it''s inexpensive and environmentally friendly. Pack tightly to avoid shifting. Always use tape that is designed for shipping, such as pressure-sensitive tape, nylon-reinforced kraft paper tape, or glass-reinforced pressure-sensitive tape. Do not use wrapping paper, string, masking tape, or cellophane tape. Put the delivery and return addresses on one side only of the package. Suggestion: Place a return address label inside the package. Stuff glass and fragile hollow items, like vases, with newspaper or packing material to avoid damage due to shock. When mailing framed photographs, take the glass out of the frame and wrap it separately. Remove batteries selfsealingbag from toys. Wrap and place them next to the toys in the mailing box. Take packages that weigh at least 1 pound into the post office for mailing.

A surcharge, in addition to the applicable postage and fees, is applied to each piece of nonstandard size mail for two reasons: it compensates the Postal Service for the added cost of manually handling nonstandard mail, and it promotes the design and use of mail that can be processed mechanically.
