So the store I work at wants to have bike baskets that you can shop with. I've designed an insert that sits at the bottom of the basket but we have no idea what to make it out of. We were thinking metal with a sticker stuck to one side or would screen printing the image onto metal be an okay option? The other thing I thought of was a thick laminated plastic kind of like a place mat. It needs to be something that can be cleaned and pretty weather/use proof.
I would look in to Polypropylene sheets, it's both offset and screen printable as well as die cuts really nice. Available in colors and different opacities. It is also recyclable and with some research you could probably find a manufacturer that uses recycled content.
Print them out of a large format printer on white adhesive back vinyl. Laminate them and then apply the decal to coroplast (yard sign material)
then put gromments on them (3 on top 3 on bottom) the zip tie them to the baskets.
