Pack 301 LD

Long dwell horizontal flow wrapper for hermetic packaging

  • Overview

    The Pack 301 LD horizontal flow wrapper is equipped with a long dwell sealing head to produce hermetically sealed packages that provide optimal product protection and longer shelf life.

    With speeds up to 150 packages/min, this innovative packaging machine can be used for the packaging of a wide range of products. It is however, especially suited for fresh, perishable goods as well as products packaged in thicker film like most medical goods.

    The machine's mechanics and controls can be adapted for simple hand fed operation or for fully automated medium-speed wrapping. Designed in accordance with the Total Productive Maintenance (TPM) principle, the Pack 301 LD simplifies maintenance and maximizes uptime.



    • Long dwell sealing times of up to 1 second ensure hermetically sealed packages
    • Seal time independent of machine speed guarantees constant sealing conditions
    • Independent temperature control of top and bottom sealing jaws
    • No jam feature - automatic detection of product between cross-sealing jaws prevents jamming, minimizing cleaning time and reducing downtime
    • Designed in accordance with the TPM to simplify maintenance and maximize uptime
    • Toolless knife change

    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
