Energy Protein Bar Chocolate Candy Flow Packing Machine
Machine Description:
This flow packing machine also called semi-automatic pillow packing machine typically refer to automated equipment where manual intervention or assistance is required in certain stages of the packaging process.
It gets its name from the pillow-like shape of the packaged product. It is widely used in automated production line packaging for regular-shaped objects such as food product of cookies, biscuit, bread, candy, energy bar, chocolate, ice lolly and non food product of soap, mask, cutlery, hardware parts, ect.

Machine Features:
The key features of semi-automatic horizontal packaging machines lie in their "human-machine collaboration" and "high cost-effectiveness." While retaining core automation functions, they reduce equipment costs and enhance flexibility by simplifying the front-end feeding process. Here are their specific features:
Specialized Design for Protein Bars, Chocolate & Candy
This horizontal flow wrapper is perfectly tailored for bar-shaped and block-shaped snacks. It adapts well to different sizes and surface textures of protein bars, chocolates and candies, ensuring smooth feeding without product shifting or damage.
Stable Continuous Feeding & Wrapping
Equipped with optimized conveyor and transmission structure, the machine realizes uninterrupted automatic feeding, film wrapping, sealing and cutting. It supports high-speed mass production and effectively boosts daily output.
Gentle Handling to Prevent Damage
The low-friction conveying system avoids extrusion, collision and surface abrasion. It keeps chocolates from melting or scratching, and maintains the complete shape and attractive appearance of protein bars and candies.
Excellent Sealing & Fresh-keeping Performance
Adopts constant-temperature heat sealing technology. The sealed edges are firm, flat and neat with great leak-proof, dust-proof and moisture-proof effects. It effectively locks flavor and extends the shelf life of finished products.
Flexible Specification Adjustment
The machine can be quickly adjusted to fit different product sizes and packaging film types. Multiple production parameters can be saved as preset groups for one-key switching, meeting diversified production demands.
Machine Details:
Machine commonly consists of manual feeding conveyor and the flow pack machine.
①The manual feeding conveyor is customized per product characteristic and placement for machine automatic conveyor to feed in bagging machine.
②Flow pack machine automatically completes the entire process of roll film bag making, product wrapping, bag sealing and bag cutting.
