Dumpling Thermoforming Vacuum Packaging Solution

Dumplings are delicate products that require packaging which preserves their shape, prevents sticking, and maintains freshness during frozen or chilled storage. Utien Pack’s thermoforming vacuum packaging solution uses flexible bottom film to create deep, supportive cavities that cradle each dumpling individually. Vacuum sealing removes air to prevent freezer burn, oxidation, and moisture loss — ensuring clean, intact dumplings for consumers.
