Step 1: Marsh Product Advisor

Optimise the performance of your
VFFS machines
for Bags, Pouches and Films

It is worth noting that vertical packaging machines must be used with a coding equipment to print batch number and dates on the packaging, as required by the food safety legislation. A date code is just one small part of a finished product, but can have significant consequences if it's printed wrong. The $500 traditional hot stamp may be cheap, but its print performance can be very poor and is often prone to human errors.

To resolve all these pain points once and for all, consider automatic technology such as digital hot stamp, which will set the production dates automatically without the need for operator input, so completely removes the opportunity for human error. This equipment used to be considered ‘specialist’ but is now available at a cost per print the same as traditional hot stamp – there is no longer an excuse for human error and allows you to remove hidden costs from your business.

Optimise the performance of your
for Bottles, Tubs, and Jars

A labeller is a machine that attachs self-adhesive labels to prescribed product packaging, widely used in food, pharmaceutical and other manufacturing industries. Like vertical packaging machines, labellers also need to equip a coding device in order to print batch numbers, and production dates on the labels. Currently on the market, labellers also come with the traditional hot stamp just like the VFFS, therefore, the following pain points exist also in the production process of labellers.

• Time-consuming manual change of brass type
• Type errors such as reversed characters
• Warm-up delays
• Punctured bags
• Poor and inconsistent print quality

Again, the solution to these problems is the same one for the VFFS - simply swap your hot stamp with an automatic digital coder, now available at a cost per print the same as before, your business will be rid of the errors and hidden costs caused by the old, mechanical hot stamp once and for all.
