Automatic Packaging Line for Sandwich Biscuits
Automatic Sandwich Biscuits Packaging Line Typical Applications
- Sandwich Biscuits: Classic sandwich biscuits with cream or chocolate filling
- Wafer Biscuits: Multi-layer cream-filled wafers
- Chocolate-Covered Sandwiches: Soft or coated sandwich biscuits
- Multipack Retail Products: Small packs of 3, 5, or 6 biscuits in a pillow bag
- Family & Bulk Packaging: Larger multipacks or cartons for supermarkets and exports
An Automatic Packaging Line for Sandwich Biscuits is an all-in-one solution that combines filling, sandwiching, and packaging into a single automated system. Unlike standard packaging lines that only wrap ready-made biscuits, this line goes further by injecting creamy or flavored fillings between biscuits to create sandwich biscuits before wrapping them.
Think of it as both a production line and packaging line in one:
- Biscuits are first aligned and prepared.
- A high-precision system injects cream or flavored filling between biscuit layers, forming uniform sandwich biscuits.
- The finished products are then counted, stacked, and packaged into pillow bags, pouches, or cartons.
Why It Matters
- Integrated process – Eliminates the need for separate filling and packaging equipment.
- Flexibility – Handles individual packs or family-size multipacks with ease.
- Efficiency – Reduces manual handling and increases throughput.
- Consistency – Ensures every sandwich biscuit is evenly filled and neatly packaged.
How It Works
Biscuit Feeding & Alignment
- Plain biscuits are delivered from the upstream production line or feeder.
- Conveyors and alignment guides ensure that each biscuit is positioned precisely for filling.
Filling Injection
- A high-precision filling system injects cream, chocolate, or flavored filling onto one biscuit layer.
- The system controls the exact weight and position of filling, ensuring uniform taste and avoiding leakage.
Sandwiching
- A second biscuit is automatically placed on top, completing the sandwiching process.
- Gentle handling ensures biscuits are not cracked or misaligned.
Counting & Grouping
Finished sandwich biscuits are counted and grouped into the required format:
- Single packs (individually wrapped biscuits)
- Multi-piece stacks (e.g., 3, 5, or 6 biscuits in one pack)
- Family-size layered packs
Primary Packaging
- Biscuits or stacks enter the pillow packing machine (flow wrapper).
- Film is wrapped, sealed, and cut, creating airtight pillow packs.
Secondary Packaging (Optional)
- Small packs are automatically loaded into cartons or larger bags, ready for retail or wholesale.
- Cartons are sealed, coded, and palletized for shipment.
👉 In short, the line transforms plain biscuits into sandwich biscuits with fillings, then packs them automatically—all in one seamless process.

FAQ About Automatic Packaging Line for Sandwich Biscuits
Q1: Can the line handle different types of fillings, such as chocolate, cream, or fruit paste?
Yes. The filling injection system is highly customizable. It can be equipped with servo-driven nozzles and interchangeable pumps to handle creams, chocolates, fruit pastes, or flavored fillings with different viscosities. The system ensures stable flow and precise dosing for each type of filling.
Q2: How do you ensure consistent filling weight and avoid leakage or overflow?
Our system uses servo-controlled filling injection with real-time monitoring. Each biscuit receives a consistent dose of filling, with deviations kept under ±1 gram. Special design in the nozzle head prevents cream “dripping” or overflow, ensuring neat product presentation.
Q3: What formats of sandwich biscuits can the line produce?
The system supports single packs, multipacks (3, 5, 6 biscuits per pack), and layered family packs. By adjusting the counting and stacking unit, the machine can switch between formats without extensive changeover.
Q4: Is it possible to run plain biscuits (without filling) on the same line?
Yes. If needed, the filling system can be bypassed, and the line can operate as a standard biscuit packaging line, handling plain biscuits in single or multipack formats.
Q5: How does the system handle fragile biscuits without breaking them?
The feeding conveyors and sandwiching unit are designed with gentle handling mechanisms, such as soft pushers and precision alignment guides. This reduces pressure on the biscuits, minimizing breakage and keeping the cream layers intact.
Q6: How does the line improve hygiene and food safety?
The entire system is made of food-grade stainless steel with easy-to-clean surfaces. Filling nozzles can be disassembled quickly for cleaning. The system also supports CIP (Clean-in-Place) options for high-standard hygiene requirements, ensuring compliance with FDA, CE, and other global food safety standards.
Q7: Can the line connect directly to my existing biscuit production line?
Yes. The line is designed for seamless integration with upstream biscuit production or baking lines. It can be customized to match your current layout, conveyor heights, and speeds, minimizing retrofitting costs.
