ABSTRACT:
The carton is machine formed into a flattened erectable configuration by folding and gluing a paperboard blank. The flattened configuration is later erected by a suitable machine and the contents are inserted into the carton and the carton is closed. In order to ensure that glue oozing from the glue seam does not interfere with the erecting of the carton, a layer of glue release varnish is applied to the inside surface of the carton opposite the glue seam. In this manner, any glue which may ooze from the glue seam during formation of the flattened form will not stick to the opposite inside surface of the flattened carton and will not prevent expansion of the flattened form to the erected form.
