The following bags were originally designed in the early 90's for a specific medical application, the packaging of microwell plates. Uses and applications have grown to include some electronic components, storage of personal moisture sensitive items, seeds, tissue samples and many other items that are sensitive to moisture, oxygen or even UV (ultraviolet) light.
IMPAK CORPORATION can produce high barrier ziplock bags in custom dimensions from 2.5" wide by almost any length up to 24" wide by several feet long.Let us know if you have a custom requirement. The best way to contact us via email: sales@sorbentsystems.com
Our ZipSeal pouches are divided into two styles. The top section of the page (items A-G) are tamper evident- providing the highest possible moisture, and gas barrier properties; the product is loaded into the bottom which then must be heat sealed. Items (H-M) are Open Zipper End (OZE) pouches made in the same style as the retail " Ziploc® sandwich bags" meaning these pouches can be opened and resealed using just the plastic zipper.
NO other manufacturer can produce ZipSeal bags in the Open Zipper End style as large as IMPAK. We have stock aluminum foil bags as LARGE as 18" x 28" (PAKVF4).
