I have some products that I've always had a difficult time getting great shots of because of the packaging.  I can't seem to find a way to remove all the reflections from the different surfaces.  The products are things like mixed nuts, candies, popcorn, etc.  They come in clear plastic zipper bags that because of their nature are not flat and cannot be flattened in any way.  The other packaging options are round tub like containers with multiple compartments holding each snack type.  These are flat but have a huge label on the front.

 

Does anyone do this type of photography and have any good solutions to getting the glare/reflections off the plastic surfaces?

You need a light box, or lighting with diffusers on it.

 

Like a big umbrella with a sock over it.

 

A light box bounces light on all sides.  You can experiment with this using Foam Core Board.

 

If you want to see some sample images from this type of setup, follow these two links:

and

See the setup picture.  If you put Foam Core across the top as well, you get even better light.... I didn't have the extra board.

 

and.... a final one... with one less board to reflect the light.

Like people with glasses, you have to use angles. You need to use a tent, or feather the lights. You will to defuse the light as well. They sell light tents, Art, has one. I don't, I use softboxes.

I missed Arts post.

Thanks, Dennis.

I was going to suggest white foam board for reflectors.  It is a bit of a tricky set up.  I used to have light shining almost into the camera to reflect soft onto fingerprints.

Thanks guys, your ideas helped out quite a bit.  I'm still unable to get them exactly perfect, but the nature of the wrinkled plastic bag I think isn't going to allow for perfection.  I'll have to settle with dealing with it in post for the areas I can't seem to get right in camera.  However getting as close as I can does save time, so thank you.

My reply may have been overtaken by events, but I have finally started watching the Table Top Photography course that I downloaded just after Xmas.  The presenter is a gent named Don Gianatti and his course covers a lot of what you are asking about.

 

Here's the link if you want to look into it a bit more:

Thanks Sailjunkie, might have to take a look at that one.

A circular polarizer can be helpful too...

 

Cheers, Don

I played around with them, and they did help a bit.  However the bags we use not being flat in any way it still had areas that would be unaffected completely.  I've also heard that there are people who use a polarizer on their lights in conjunction with a polarizer on their lens.  Allowing for much finer control.  I'm thinking of giving that a go if I can find them somewhere at a decent cost.  Thanks for the suggestions though everyone!  It's slowly getting better.

I bought polarizing material from http://polarization.com/ and then made foam core frames that fit over 20" x 20" softboxes.

For this shot, I wanted controlled reflections without them being blown out...

Two other things you can try, first is a light tent.  With this technique, it helps if you are handy with post processing.  The images are slightly off color and lack that certain pop.

 

The other is a globe.  My 20" has a 7 1/4" opening.  

 

This is my 16" globe, the opening is 5 1/4".  I made a styro foam stand and cut a piece of foam core to fit inside....

SOOC, to be fair, this was a set up shot and is slightly out of focus :)
