The advantages of a well-designed and manufactured thermoform tells their own story. Known as birefringence, the repeating rainbow pattern is a sign of stress in the package. More repeating violet bands, higher stress. Fewer repeating violet bands, less stress. Lower stress blisters are much more resilient and resist cracking and warping better than blisters with high stress levels.
The key to minimizing stress is maintaining the proper sheet temperature. Computer Designs uses closed-loop infrared termal imaging to achieve the optimum heat profile for a given material. The scanner monitors the temperature of the sheet constantly and adjusts the oven settings - as much as 16 times in one minute. Quality Assurance validates the entire process, so our customers are assured the package is to specification.
