Something as easy as applying a shipping label seems easy, but there are some helpful tips you could use. First of all make sure that the Package that you’re affixing the label to is clean and dust free. It wouldn’t hurt just to run a very lightly damped rag over the surface just to get that dust off. Then wait a few minutes so that any dampness can evaporate before applying the label. Make sure that the surface you’re affixing the label to is free of any oils or materials that are flaking off such as old paint or old labels. Don’t affix your labels to surfaces that have old clear tape, the labels might be more prone to come off. Hey, there are a lot of small companies out there that just can’t go out and buy brand new boxes with perfectly clean surfaces. Anyway re-using boxes is better for the environment. It might not look as pretty, but you’re saving the planet one cardboard box at a time.
