Pack 301 IN

Inverted Flow Wrapper

  • Overview

    The Pack 301 IN flow wrapper gently transports products by carrying them on top of the film from the former through the cutting head minimizing jams and ensuring superior package appearance. This gentle product handling makes the machine ideal for soft products, multi-packs, and other products that are difficult to handle using a standard upright flow wrapper design.

    The Pack 301 IN features a modular film backstand that can be located in various positons relative to the infeed and wrapper. This allows users to optimize the film path, avoiding unnecessary film path length, resulting in supreme package appearance, minimal film waste, and few rejects.

    To further enhance product transport, the Pack 301 IN was designed to integrate with a variety of infeeds such as flighted, lug-less, trough style and belt feeders to meet a variety of maufacturing needs. Additionally, the finwheel assembly can be easily raised or lowered to accomodate products of different heights for short changeovers.



    • Inverted design feeds film from below the product to securely carry hard to handle product through the wrapper
    • Film backstand can be located in various positions for ideal product transport and minimal film waste
    • Flexibility to integrate with a variety of infeeds (flighted, lug-less, trough style, belt feeders)
    • Hinged overhead finwheel assembly provides easy access to film for fast set-up and clearing of jams
    • Vacuum conveyor to cutting head precisely controls product and film
    • Stainless steel product contact points

    White Paper

    Product Distribution Conveyors vs. Robotic Feeding

    This white paper addresses the selection criteria involved in identifying an optimal feeding solution as part of an integrated packaging line. Many manufacturers face this decision when automating their packaging line to achieve higher outputs or lower costs. This paper will discuss the key considerations that should be kept in mind when making a decision and compare Delta robotics and product distribution conveyors. Both technologies have there place in modern packaging lines. The decision to choose one technology over the other often can often be made after evaluating the suitability of each versus the following three characteristics of the packaging line and product:

    1. Pack Configuration

    2. Product Characteristics

    3. Operating Environment

    More information on Product distribution conveyors versus Robotic Feeding solutions you will find in our white paper „Product Distribution Conveyors versus Robotic Feeding“. Feel free to download the white paper via our
