ABSTRACT:
The present invention relates to a packaging method. It also relates to a packaging bolster and to a packaging line employing the method of the invention. The bolster of the invention, adapted particularly to the method of the invention, includes at least one flexible base material or support of elongated shape and indefinite length, intended to be trimmed to the dimension required at the packaging site, the base material carrying spacer elements for spacing apart the product to be packaged at predetermined positions. The bolster is remarkable in that the base material includes at least two films weldable in such a way as to make cushions or bulges filled with a swelling agent.
