Below is a list of Vacuum Packaging manufacturers from Orangeburg, New York. Vacuum packaging can refer to both those items held or displayed in reduced oxygen containers and any and all packaging materials produced through vacuum forming. Blister packs and clamshells are the most ubiquitous example of vacuum formed packaging materials and are commonly used in a number of industries. The food industry, however, is the most prevalent application of vacuum packaging as a process rather than product.
