I use PayPal for my online business. Will I be able to print the shipping label and packing invoice all on one sheet with these? How would that work and would anyone know how to set it up? Right now I am using a dymo label printer and still having to print the packing slips then cut and put in order.

With PayPal shipping, we offer our OL1569IF - 7.375" x 4.5" Integrated Form Label that would be better suited for printing your shipping label and packing invoice all on one sheet, since PayPal requires the 7.375" x 4.5" label size. https://www.onlinelabels.com/Products/OL1569IF.htm For more information on how to create a PayPal shipping label, please review our help article included below: https://www.onlinelabels.com/articles/how-to-create-paypal-shipping-labels.htm If you would like to request samples of the OL1569IF labels for testing with PayPal, you are welcome to use our sample request form. https://www.onlinelabels.com/samples

These labels were fine to apply on boxes etc but do not hold on to compostable bags (with which we have no problems with thermal label rolls). I believe the glue it not enough?

Our Integrated Form Labels (IF) feature a permanent adhesive that works well on most surfaces. However, there is a wide range of factors that can contribute to how well a label adheres to the surface it’s being applied to so we’ve included some recommendations below. -It’s important to ensure that the surface is clean and free of any debris, dust or moisture before attempting to apply your label. -Applying the center of the label first, and then continuing to apply pressure outward will ensure a nice, even application that should promote better adhesion. -Be careful when handling the label before application. Oil from your fingers can negatively affect the strength of the adhesive - try to hold the labels by the edge and touch the adhesive as little as possible. -Remember, our labels are pressure sensitive, so be sure to use some force when applying them to your surface or container. If you’ve followed the suggestions listed above and are still experiencing issues please feel free to send us a support ticket at the link below with details on the surface and method of application.
