We have the strongest Waterproof Barcode Labels that you can use in any environment. These are essential if you want the printing to hold up long term, and you don't want the labels to fall off.
All 3 levels of our barcode labels are waterproof. Our Strongest level is most robust, made with laminated polyester, and is 10 mils thick plus 5 mils of 3M adhesive on the back. The next level down is 5 mils of laminated vinyl, and is even stronger than what sign companies use on store windows.
Normally if barcode labels are used outdoors they need to be waterproof. We have seen photos of other barcode labels that were used outside and the printing faded to the point where you couldn't read it. Don't waste your time & money on cheap labels that are not waterproof! Our barcode labels are made to withstand various levels of exposure, so pick which one meets your requirements.
