Inverted Long Dwell Flow Wrapper
Hermetic Sealing for Difficult to Handle Products

Products
Fresh produce, fresh bakery goods, meat and cheese, and products packaged in thicker film, such as most medical goods. The Pack 301 ID is ideal for the packaging of multipacks, soft, sticky, flexible and difficult-to-handle products, that require hermetic sealing.
Functional Principle
To ensure secure product handling and reduce jams, the Pack 301 ID’s inverted design gently transports products on top of the film from the folding box through the cutting head. In order to produce air-tight packages the machine features a long dwell cross sealing system.
Hermetic Sealing
The long dwell cross sealing system allows for sealing times of up to 1 second, resulting in hermetically sealed packages for extended pro-duct shelf life and safety. With the sealing time being independent of the machine speed, consistent seal quality is ensured at all times, even during ramp up and ramp down periods. This results in consistent high-quality packages and a reduction of product and film waste. Since the hermetic seals prevent any exchange of gases, the Pack 301 ID is ideal for applications that require Modified Atmosphere Packaging (MAP)
High Flexibility
The modular machine backstand can be located in various positions relative to the infeed and wrapper, allowing users to select the optimal film path, decreasing film waste and rejects and speeding changeovers. Quick changeovers are further enhanced by reproducible settings and fast and easy sealing height adjustments.
Fast and Easy Maintenance
The machine features an open construction for easy access and has been designed according to the Total Productive Maintenance (TPM) principle. Knives can be changed and cleaned without tools and the transport belt at the sealing station is easily exchanged for cleaning and maintenance benefits. The hinge-able finwheel assembly can effortlessly be lifted in order to get access to the transport belt.
