I think the main problem is your packaging, as Stan mentions in his comment. The packaging is wrinkled such that, no matter where you place your lights, you are going to have some surfaces reflecting onto the camera. If you try to move your lights closer, to make the light softer, you'll have light bouncing off those things at literally every possible angle.

A few ideas.

• Open the packaging from the back and remove the contents and attempt to flatten out those wrinkles. Carefully refill the packaging with something stiff and flat to give it some shape, but at the same time keeping the wrinkles at a minimum.

• If you have modelling lights, you may be able to carefully tweak the position and angle of each package to reduce the amount of glare.

• As Jim mentioned you do have some harsh shadows, so you must have pretty strong lighting from both sides. Perhaps use a key light right over the camera and lower the power on the lights to the side - keep enough side-lighting to give some depth, but not too much depth, which might be the problem here. Can't be sure that will work at all, and you may need to angle some of the packages because if they are square to the camera, of course they'll just reflect back.

• If all else fails, shoot a number of shots, moving your lights around, so in post processing you have a variety of shots to choose from. Any problem areas, mask in areas from other images that have less glare on that particular package. In this case I think it might be far easier to "head swap" a few problematic packages in post than try to perfect the lighting.

And if you haven't read Light, Science and Magic, that's the bible of doing this sort of thing - reflective surfaces, angle of incidence = angle of reflection, all that good stuff.
