1. Heat Sealing Machines
- Function: Cartridge heaters are installed in heat sealing bars or jaws to provide uniform heat across the sealing surface. This ensures the proper bonding of packaging materials like plastic films, bags, and pouches.
- Usage: Set the cartridge heater at a specific temperature to match the type of material being sealed. The heater ensures a tight, leak-proof seal by applying heat and pressure for a designated time.
2. Shrink Wrapping Equipment
- Function: In shrink wrapping, cartridge heaters help maintain the necessary heat to shrink plastic films tightly around products. The heater is installed in the sealing bar or shrink tunnel.
- Usage: The heater generates enough heat to trigger the shrinking process without damaging the product, ensuring a smooth and secure wrap.
3. Hot Knives for Cutting Plastic Films
- Function: In machinery where plastic films need to be cut or perforated, cartridge heaters are used to heat the cutting knife, allowing it to slice through the plastic smoothly.
- Usage: Install the cartridge heater in the cutting knife assembly to maintain a high temperature. This ensures a clean, precise cut without leaving rough edges or damaging the film.
4. Blister Packaging and Thermoforming
- Function: Cartridge heaters are used in thermoforming machines to heat molds that form plastic sheets into desired shapes (like blister packs).
- Usage: Cartridge heaters are embedded in molds or platens, heating them uniformly. The heated mold then presses against plastic sheets, creating a vacuum or pressure-formed shape for packaging products.
5. Labeling Machines
- Function: Cartridge heaters are installed in the hot-stamp printing heads of labeling machines, which apply labels using heat.
- Usage: The heater maintains the necessary temperature to activate adhesives on labels or emboss labels onto packaging, ensuring the label sticks properly without damaging the material.
6. Heat Transfer in Packaging
- Function: Cartridge heaters are also used in machines that perform heat transfer printing onto packaging materials, including designs and barcodes.
- Usage: The heater ensures precise heat distribution to transfer ink or other materials from a film onto the packaging.
