Small-bubble wrap (3/16") conforms to product shapes and excels at surface protection — it's your wrapping material. Large-bubble wrap (1/2") absorbs impact from drops and fills voids for heavier items — it's your cushioning material. Using large bubbles to wrap delicate items leaves gaps. Using small bubbles to fill big voids underperforms on impact. The match between product and bubble size matters more than most sellers realize.

Most packaging damage happens because only the top or bottom of a box is padded. The industry standard for fragile item shipping calls for at least 2 inches of cushioning on all six interior surfaces. A single layer of bubble on the bottom and nothing on the sides leaves your product one sideways drop away from a return.

When a product can shift inside its box, it will. Every stop, jostle, and conveyor transfer lets it build momentum and strike the interior walls. The fix isn't always more void fill — it's a box closer to the product's size so movement is minimized before cushioning has to do its job.

A box sealed with a single strip of thin tape fails more often than most sellers expect. The H-tape method — full center seam plus both end seams on top and bottom — is the industry standard because it distributes stress across the entire closure, rather than relying on one strip. One extra pass of tape is cheap. A lost customer isn't.

Packages get stacked, sorted at high speed, loaded into hot trailers, and dropped at varying heights throughout their journey. A package that's fine if handled carefully is not a package that's fine. Design for the conditions your shipment will actually encounter — not ideal handling.
