Pre-formed tray with vacuum
New Angle - Pre-formed tray packaging for produce
Pre-formed tray packaging for produce often applies materials like APET, EVOH, and PE.With such packaging, the natural air in the package is replaced with fresh-keeping gases which is often a combination of carbon dioxide, nitrogen, and oxygen. The actual gas ratio depends on the food's properties.
It’s also optional to apply colored bottom film to make the bottom tray. And the design of extra beam ribs can make the package more firm.In this way, we can protect the food from moisture and microorganisms.
