So you can search until you are blue in the face... I should title this "SPINNING YOUR WHEELS" because that is how finding OEMs seems. If you take good notes and build solid lists, you can narrow your list and find a handful of good options to do the tighter price/timeframe/customer service/references comparison to make your decision on the best company to partner with... because they will be a partner!
Here are some resources to help:
- Retail Packaging Association
- GlobalSources.com (has a China section if that is what you are into)
Many other directories exist, but I like these the best. Some industries have their own directory or two, such as retail packaging association. Just note that these sites take listings as advertising and it is not comprehensive. More of the small mom and pops don't advertise like this (and they don't have a searchable site... if at all) so check our your local yellow pages or call around to local companies who may supply products to them (paper to a book binder or textiles to a seamstress) and see if they will help one of their customers out.
Local is better - less shipping costs, more of a partnership cause you do business face-to-face, and your support your local economy. What could be better.
