Challenge One: The client required a latex diaphragm delivered on rolls for ease of automatic dispensing. The diaphragm, however, did not require adhesive. How the diaphragm would stay on the liner without adhesive was the first challenge.

Solution One: We searched for an ultra removable adhesive that contained a high differential release (i.e. one side of the adhesive or liner could be removed far easier than the other side.) This differential release is most often controlled by the silicone content applied to the release liner. In this case, an ultra removable adhesive allowed the part to be removed from the carrier without any adhesive residue. The tight release between the adhesive and the liner allowed the adhesive to stay on the liner after the part was removed.

Challenge Two: Tolerances remained tight. The part has a 0.003 tolerance in the x, y and z dimension. Maintaining this while working with the elastic properties of natural rubber and ensuring compliance within the lot was the second challenge.

Solution Two: Label Innovation made certain that the rubber was under the least amount of tension possible - its own weight. After converting, a sample population was measured. That data was then used to statistically calculate the mean, standard deviation and upper and lower control limits. Because the mean plus or minus three times the standard deviation was within the upper and lower specification limits, we had a 99.8% assurance that all parts will fall within this range.
