ZS-720W 5-Servo Reciprocating Packaging Machine (Box Motion Flow Wrapper)

Why Choose Reciprocating (Box Motion) Technology?

Standard flow wrappers use rotary cutters that limit product height and sealing quality. The ZS-720W solves these limitations:

• Handle Taller Products: The box motion jaw design allows for products up to 130mm in height (standard machines usually stop at 60-70mm).

• Superior Seal Integrity: The sealing jaws travel with the film, applying heat and pressure for a longer duration. This creates a hermetic (airtight) seal, essential for frozen foods (dumplings) to prevent freezer burn, or for extending shelf life in bakery products.

• Gusseting Capability: The reciprocating motion makes it easier to create neat, gusseted (block bottom) bags for a premium shelf appearance.

Application Scenarios

This machine is built for "Difficult-to-Pack" items:

• Frozen Food: Trays of dumplings, frozen meats, and seafood (requires airtight sealing).

• Bakery: Large cakes, loaf bread, and pastries in trays (requires gentle handling and tall clearance).

• Fresh Produce: Bulk vegetables, leafy greens, and fruit trays.

• Industrial: Large paper boxes, multipacks, and hardware kits.

Key Features & Technical Advantages

• 5-Servo Motion Control: The entire machine is driven by a motion controller with 5 servo motors. This ensures absolute precision in film feeding, pulling, and sealing positions.

• Massive Capacity: Supports a maximum film width of 720mm, allowing you to wrap large, family-sized bundles or wide trays.

• User-Friendly Interface: Features a large LCD display where all parameters (seal time, speed, cut position) can be set digitally.

• Hygienic Design: Built with engineering mechanics in mind, the open frame design makes it quick to clean and maintain—crucial for food safety standards.

• Flexible Setup: The stop position, print position, and cutting position can be set arbitrarily without mechanical adjustments.

Technical Specifications

Service & Support

• Custom Engineering: We can integrate gas flushing (MAP) systems for extended shelf life applications.

• Installation: Due to the machine's size and complexity, we offer detailed video installation guides or on-site engineer support.

• Warranty: 1-Year Warranty on servo motors and PLC.

Frequently Asked Questions (FAQ)

Q: Why is the speed (60 bags/min) lower than the ZS-500S?

A: The ZS-720W uses "Box Motion" sealing. While slower than rotary sealing, it provides a much stronger, airtight seal and handles much taller products. It prioritizes quality and size over raw speed.

Q: Can this machine pack frozen dumplings with trays?

A: Yes, this is the perfect machine for it. The reciprocating seal ensures the bag is airtight, preventing frost and freezer burn inside the package.

Q: What is the maximum product height?

A: It can handle products up to 130mm high, making it suitable for large cakes or stacked products.
