Due to a rapidly aging society, easy-to open packages have moved into the focus of the packag-ing industry. For the field of food and cosmetic products on one hand but also for medical products on the other hand these packages are indispensable today.
The test standard DIN 55 409 and the guide values for peelable packages (both developed by Fraunhofer IVV Dresden) are being very well received and are in high demand.
The production of a high quality, safely closed and easy to open package imposes high require-ments on the process control, the packaging material and the quality assurance because of the reduced seam strengths. Contamination of the seam and deviations in the packaging process cannot generally be avoided. Nevertheless, it must be ensured that the product reaches the con-sumer in an excellent quality. The question arises, how strong a peelable seam must be to at least endure the transport, handling and storage processes on its way from the manufacturer to the consumer and which variables exist to minimize the strain on the sealed seam.
The aims of the project are:
