Did you read this article before posting the link? It's admirable that you want to help fellow CCers by googling for them, but the info in that article suggests that co-packing is for large companies with years of experience. Unfortunately, our OP is neither.  0_0

Aaaaaaa, yeah......Yes I did. I also read yours:

The kind of private label business relationship you are referring to is called co-packing. But typically, a food business looking for a co-packer will not contract with a small business or a new business with no track record. Sorry.

Funny, I thought the link explained why you should do your research on the subject and what it entails with resources at the bottom of the article that might offer more information to the OP about private labels and co-packing since she did ask:

"The question I have is who are the suppliers that people like windsor cakecraft are going to for there own label products?? Any help will do"

I was researching info for labels and packaging ideas for a brownie mix  to sell at an upcoming event. Like the last three above and these below which have nothing to do with what she was looking for but were on a list of links I had opened in MS Word. I copied and pasted them on here and tried to delete mine unfortunately my computer crashed.

That is why I posted, "tried to edit this in but waited to long , computer problems:(", when I re-logged on I could not edit it again.

I was just trying to help but I should have just left your post as the final word which is more admirable.

Sorry
