Constantia Flexibles has introduced the new Live Stress Check for its Constantia Coldform, which is a pharmaceutical packaging solution. Constantia Live Stress Check is a tool that determines the strain level applied to coldform foil and the quality of the forming process when running on blister lines. Results are used to optimize the manufacturing process by uncovering improvements that can be made concerning forming plug designs, plug materials and process setup. To perform the stress check, a pattern of high-resolution dots is printed on the Coldform laminate which, when stretched, changes. The Live Stress Check sample, with cavities that were formed under production conditions, is inspected with a camera system and special software to determine these distortions. Afterwards, an automatically-generated 3D-image illustrates the degree of strain at various areas of the blister.
Constantia Flexibles also offers a simulation of the cross-permeation in coldform blister packs. This concerns the moisture that permeates into a blister cavity in very small quantities along the inner layers of the blister’s punched edge (moisture permeation is only possible along the punched edge because the base foil’s aluminum creates a 100% barrier against water and oxygen). Such cross-permeation can be controlled using laminates whose plastic layers provide a higher barrier to water vapor on the coldform laminate’s inside layer.
