Pack 401

High speed wrapper designed for full automation

  • Overview

    The Pack 401 horizontal flow wrapper combines proven technology and application know-how from Bosch Packaging Technology companies around the world, making it truly a best-in-class machine. It marks the next generation of Bosch packaging machines that are available globally and supported locally.

    New features on the Pack 401 flow wrapper provide a high degree of reliability and efficiency. The latest technology in gap control results in consistent and precise seal integrity. A standard dual spindle backstand with power feed roller allows for full automation, providing improved splicing, cutting, auto tracking and tight cut offs.

    The Pack 401 flow wrapper can operate as an independent unit or can be integrated with other packaging systems such as Delta-robotics, secondary packaging equipment, product handling equipment, and various infeed modules.

    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“.

  • Application

    The Pack 401 flow wrapper covers a large variety of high-end applications and is ideal for handling bakery and confectionery items such as biscuits, chocolate and bar-type products, as well as non-food products and much more.
