Best labels for poly-bags

Hello.
First timer planing for first shipment to Amazon fulfillment centers.
Items will be packed in transparent zip-lock bags. Current labels, some cheap 32 labels per page, do not want to stay on the bags, as soon as items are placed inside.
Currently I have 3 options to consider:
*)Place a scotch tape over labels, keeping them in place;
*) Print the labels on thicker paper and place inside the bag, showing the information to outside through the bag;
*)Find a good brand of labels that really stick to poly-bags or bubble wrap.

Additional question regarding fragile items - Do Amazon accept stock, wrapped in layers of bubble wrap, scotched close and label present on outside?

Kind regards
