white bar codes with white background

Hi,

We're struggling with our bar code scanning rate for Baxter's "Mini-bag Plus" containers. The bags have a white bar code, and our scanners won't read them if there is fluid behind the bar code or if there is a white label on the other side of the bag.

The only way that we can get the bar code to scan is if we squeeze the bag so that there is air behind the bar code AND also angle the scanner so that the flat water surface is below and serves as the background.

I've attached some pictures to illustrate this. Have any of you solved this issue? I'm not sure why they used white bar codes.

Thanks!
Dan Sheridan
