HFFS Application
Chocolate Bar Flow Wrapping Machine
Chocolate bars are regular solid products suited to horizontal flow wrapping, but surface temperature, scuffing, breakage and precise printed-film registration can affect pack quality. The machine and production environment must keep bars consistently oriented and clear of the sealing zones.

Illustrative packaging example
Published HYS Configuration Facts
- HFFS model range: HFS-260, HFS-350 and HFS-450
- Published speed range: 20–250 packs/min
- Published finished bag widths: 25–110, 25–150 and 50–200 mm by model
- Published suitable film thickness: 0.03–0.06 mm
Final model, options and output are confirmed from product and package samples.
Custom functions: Nitrogen flushing, dust extraction, metal detection and checkweighing require a customized machine or line configuration.
Temperature and Product Handling
- Provide bar length, width, height, weight and acceptable surface-contact method.
- Product temperature and room conditions should prevent softening, bloom or transfer to guides.
- Flights and guides must maintain pitch without chipping corners or marking the surface.
- Automatic feeding must be matched to the molding, cooling or upstream conveyor output.
Printed Film and Sealing
- Confirm film structure, thickness, friction, eye-mark position and heat-seal window.
- Artwork registration should be tested at the intended speed.
- Bag dimensions must leave clean end-seal clearance beyond the chocolate bar.
- Seal temperature and dwell must protect both package integrity and product appearance.
Acceptance Test Inputs
- Product samples at realistic production temperature.
- Printed or plain film roll and final pack dimensions.
- Required good packs per minute and upstream spacing.
- Coding, easy-open, reject and downstream carton requirements.
Frequently Asked Questions
Potentially, when all sizes fit the model range. Bag length recipes may change, while width or height changes can require forming-set adjustments.
Only a rated machine range can be discussed. Stable good-pack output must be tested with the real bar, film, dimensions and seal criteria.
