The Hendi concrete tray sealer is designed for the safe packaging of fresh food. It is aimed at catering companies, restaurants, and supermarkets. The robust and stable construction is made of stainless steel. The lid features a spring mechanism for easy and safe opening. The sealing process is facilitated by the use of bearings and special slippery material. The pressure suppressor ensures airtight packaging and prevents the containers from being crushed. The handle is made of durable material. An automatically folding French knife is placed on a special rail and cuts the film precisely behind the sealed container (air-cut technology). The sealing surface is coated with titanium, which prevents the film from sticking and allows quick sealing within 1-3 seconds.
