How do I choose the most suitable products for packaging with wrap-around and American (RSC) cases?
Wrap-around carton is formed by wrapping the carton die around the grouping of products in their primary packaging. To ensure the proper sealing of the cardboard, it is necessary that the glue applied by the guns is subjected to pressure for a few seconds and, therefore, that the grouping of the primary packages inside the cardboard exerts a contrasting force with respect to the external compression applied. In other words, the size of the wrap-around carton must be carefully defined based on the grouping of primary packages to be wrapped. If the products to be packaged are in rigid packages – such as cardboard boxes, bottles or jars in glass or plastic – determining the size of the grouping is direct. If, on the other hand, the products to be packaged are in flexible packaging – such as envelopes or bags – it is necessary to take into account a certain deformation of the packs before their grouping exerts a contrasting force with respect to the compression applied from the outside of the carton.
