A Guide To Barcodes Part 2

We have seen that barcodes are now used extensively throughout most industry and retail environments and depending on the application that you need the barcode for, will depend which symbology is used. There are seven commonly used symbologies and we will be more than happy to discuss with you the one that is right for your particular requirements. The most common of these are code 128, EAN 8 and 13, and the latest which is QR code.

What has then to be considered is the material that the barcode will be produced from; again this will depend upon the application. Most common is white paper; however paper can be damaged by light, water, dirt and chemicals and may be torn. Polypropylene, polyester and aluminium are other materials which will withstand the rigours for labels that are likely to be exposed to harsh environments or subject to hard use.

Laminate coatings can be applied to the label to improve their performance in many different applications; coatings are available that increase performance and durability. The all important adhesive will also determine how your barcode will withstand everyday use. Many combinations of adhesive materials are available. Some applications require permanent labels that resist exposure to temperature extremes, high humidity, chemicals or outdoor use. Again, we will be happy to advise you of the most suitable adhesive to use for the environment your barcodes will be used in.
