Traditional rust prevention for steel items in the marine environment meant spraying oils onto the metal surfaces and then wiping off before use. Items such as hand tools, fishing hooks, screws, nut and bolts are constantly being discarded due to rust. A typical mariner is all too familiar with a tool or tackle box full of rusted items.

Corrosion inhibitors are lined on the plastic sheeting that make up the bag. In the package environment these inhibitors surround the parts and volatilize to form a protective molecular layer. When these chemicals volatilize, they release vapors which are attracted to the metal surfaces due to their polar orientation.

The corrosion inhibitor molecules align on the metal surfaces to a depth of three to five molecules migrating into recesses. This layer of molecules passivates the charged surface and creates a barrier that prevents oxidation. Protected parts are easily removed from the bag and are ready for immediate use with no smell or residue.

Leland developed this out of necessity for their own business of making CO2 cylinders for inflatable life jackets. The raw steel cylinders rust very quickly without any protection. Rather than follow a traditional oil bath method for rust prevention, the company choose a responsible way to protect their goods; to place the raw steel cylinders into these bags for transport and storage prior to electroplating zinc as the final protective step.
