Product Overview

From the Roll
to the Finished Pack.

On an automatic packaging machine the film is fed from the roll, formed around or over the product, filled, sealed and cut into finished packs in one continuous process.

The film therefore has to run straight through the machine, seal reliably at line speed and hold print in register from pack to pack. Web handling, mechanical performance and heat sealing are designed together for your equipment.

How It Works

  1. 01

    Unwind

    The film is fed from the roll into the machine.

  2. 02

    Form & Fill

    The machine forms the pack and the product is filled.

  3. 03

    Seal & Cut

    The pack is sealed and cut from the web.

Applications

Suitable Foods.

A first recommendation by food type. The final structure is always confirmed with samples on your own product and machine.

Samples & Technical Support

Tested on Your Machine
Before You Order.

A structure only proves itself on your product and your line. Our engineers propose a film or bag, prepare samples and review the trial results with you before production starts.

  • Samples Tested on Your Machine

    Trial samples are made to the proposed specification so you can check forming, sealing and pack appearance on your own equipment.

  • Structure Proposal

    Tell us the food, storage conditions and machine. We suggest the layer structure, barrier level and thickness to start the trial with.

  • QC Report with Every Lot

    Incoming, in-process and finished-product checks in our in-house lab, with the inspection report supplied with each delivery.
