Explaining Packaging Jargon
A handy A-Z guide of packaging terms
Ever struggled to understand your packaging designer? Found yourself bogged down in technical terms that mean nothing? Or just wished you could have things explained in plain English?
You’re not alone!
Whilst there are occasions where unfortunately there is no alternative to a technical term or phrase, certain amounts of jargon can be easily avoided.
But what about those specialist terms? Until now there hasn’t been a single place to find an explanation of packaging industry terms. But this is exactly what this guide aims to achieve.
Besides specialist terms, it also covers a wide range of brand, product and process names that you may be unaware of, all available in one quick reference guide to use as and when required.
So as well as getting a straight-forward explanation of a huge range of packaging terms, you can use it to potentially boost your own knowledge of packaging too.
