Thermoforming bottom web films are multi‑layer co‑extruded forming roll‑stock for automatic thermoforming deep‑draw packaging machines. The film is heated and vacuum‑formed into cavities on‑machine to hold products, then sealed together with matching top web/lidding film. Excellent deep‑drawing formability, high puncture resistance, optional medium‑high oxygen barrier with EVOH. Compatible with vacuum and MAP modified atmosphere packaging for meat, seafood, cheese and processed food.
