HEAT SEALER】This heat sealer uses a large-size constant temperature heating workbench (30*40cm) with a multi-function LCD display panel and dual temperature display, With memory function, you can set it once and use it easily. UNIFORM HEATING】 The packaging machine uses a special heating workbench made of aviation-grade aluminum. The multi-tube technology has high conduction efficiency, uniform heat transfer, and will not deform after long-term use. PRECISE TEMPERATURE CONTROL】 The cellophane packaging machine uses a microcomputer chip for precise temperature control, PTC positive temperature coefficient heating, automatic constant temperature, and a temperature difference of ±1℃, so it is not afraid of dry burning. The temperature range is 0℃-200℃. SAFE AND CONVENIENT】 The shrink packaging machine uses a three-hole radiator to dissipate heat evenly and is not hot. It uses a safety edge to wrap the aluminum plate to effectively absorb heat. Equipped with a white heating panel cover, you can cover the heating plate when not in use to prevent burns.
