Desktop heating sealing machine engineered for consistent, durable box sealing and film conversion. Designed for small production lines, sample runs, and cosmetic packaging, this unit combines precise temperature control, even heating, and practical storage to streamline work on the bench. Key benefits Reliable, uniform seals: Special heaters and a aluminum alloy heating plate provide even temperature distribution across the surface for consistent sealing results. Precise temperature control: Sensor closed loop PID control maintains stable temperatures with an automatic constant temperature difference of +/ 0.5 C, improving conversion consistency. Practical, spacesaving design: A hinged lid covers the heating plate when not in use to reduce contact with the hot surface. A hidden storage box keeps tools and accessories organized and accessible. Durable performance: The aluminum alloy plate resists deformation at temperatures for long term use. Compatible with common films: Accepts cellophane films used for normal packaging and cosmetics packaging. Important attributes Heating plate size: 400 x 300 mm Film compatibility for normal packaging boxes: cellophane film thickness 0.022 mm or 0.025 mm Film compatibility for cosmetics packaging boxes: cellophane film thickness 0.03 mm or 0.04 mm Temperature control: Sensor closed loop PID control, automatic constant temperature difference +/ 0.5 C Construction: aluminum alloy heating plate; special heaters for uniform temperature distribution Features: Protective lid, hidden storage box Typical use scenarios Cosmetics packaging: Seal cosmetic boxes using thicker cellophane films for neat, secure presentation. Small batch production: Desktop setup for sealing small runs of retail or promotional boxes with repeatable results. Sample and gift packaging: Fast, reliable sealing of presentation boxes and sample packs where consistent appearance matters. This machine is intended as a desktop heating sealing solution for converting and sealing boxes with specified cellophane film thicknesses and a 400 x 300 mm heating plate, offering uniform heating and precise temperature stability for reliable production.
