For this use, I would definitely recommend that you consider our weatherproof products. We have a variety of options available. If you are using a laser printer then I would recommend the OL8500LP (weatherproof polyester for laser printing). If you are using an inkjet printer then I would recommend the OL8500WJ (weatherproof matte for inkjet printing) or the OL8500WI (weatherproof glossy for inkjet printing). Greasy hands have the potential to stain the label so you would need to see if you are happy with the performance of these products for your specific use. We are happy to send some samples for you test at no charge if you would like to fill out our sample request form at https://www.onlinelabels.com/samples.
