Raghav band sealer machine

Raghav band sealer machine

A horizontal continuous band sealer is an automated packaging machine designed to seal pre-filled thermoplastic pouches, bags, and film materials while lying flat on a motor-driven conveyor belt.Unlike vertical band sealers (used for liquids or powders that spill when laid flat), horizontal models are ideal for dry, solid, or flat-packed products like snacks, hardware, bakery items, electronics, and spare parts.

Motorized Conveyor Belt: Moves pouches smoothly through the heating and cooling zones at a synchronized speed.

Heating Blocks & Thermocouple: Temperature-controlled brass or aluminum heating blocks melt the inner lining of the pouch material to create a secure weld.

Cooling Blocks: Air- or fan-cooled blocks solidify the melted plastic under pressure right after heating, ensuring a clean, leak-proof seal.

Teflon Sealing Belts: Seamless PTFE bands carry the bag mouth through the heating and cooling elements without sticking to the plastic.

Embossing / Printing Wheel (Optional): Applies batch numbers, manufacturing dates, or expiry codes directly onto the sealed seam using solid-ink or embossing wheels.

Feed: The operator places a filled pouch flat onto the moving conveyor and guides the open top edge into the machine’s intake slot.

Heat & Seal: Motorized belts grip the pouch edge and transport it through adjustable heating blocks that melt the inner pouch layers.

Cool & Press: The pouch edge immediately passes through cooling blocks and knurled pressure wheels to set the seal and create a neat pattern.

Exit: The continuously sealed package exits the conveyor, ready for secondary packing or retail display.
