A packaging method includes feeding products, ordered into two rows, into a first ring winding unit of extensible film and winding the products in a first film having a first rotation direction to form a continuous packaging or bundle; feeding the wound products to a second ring winding unit of extensible film in a second film having a second rotation direction opposite to the first rotation direction to form a continuous packaging or bundle with two layers of film; and feeding the continuous packaging or bundle into a cutting unit, which moves in synchrony with, and cuts, the continuous packaging or bundle transversely into finished groups of products. A ring winding machine is provided at each of the two ring winding units, obtaining a continuous winding also when the film becomes exhausted in at least one of the two ring winding machines. A packaging machine is also provided.

Packaging method using extensible film and machine therefor includes feeding the groups of products, spaced apart and separate from each other, into a first and a second winding units to wind the groups of products with a first and a second extensible film disposed in opposite rotation directions to form a continuous packaging wrapped in two layers of film in opposite directions; and advancing the continuous packaging into a cutting unit, which cuts the continuous packaging transversally into finished groups of products. The winding step in each of the two ring winding units is selectively and alternately actuated with one of two ring winding machines provided at each of the two ring winding units, thereby achieving a continuous winding of groups of products even when the extensible film in at least one of the two ring winding machines at each of the two ring winding units is exhausted.

A thermoform packaging machine comprising a forming station, a sealing station, and a cutting station for separating sealed packaging troughs from one another. The cutting station may comprise at least one cutting unit which is adapted to be positioned within the cutting station at different positions in the production direction. The cutting station may comprise a support that supports bottoms of the sealed packaging troughs conveyed into the cutting station for the purpose of separation from below. The support may comprise a plurality of support elements arranged in a horizontal bearing plane and which form a gap at a position in the support at which a cutting operation takes place according to the position of the cutting unit. The gap may be repositioned by moving the support elements to different positions to position the gap to accommodate a different position of the cutting unit within the cutting station.

A method for packaging and installing high performance insulation of a loose, granular, moisture-resistant nature, suitable for providing insulation in walls, ceilings, or other cavities in traditional buildings, cabinets or other structures requiring thermal or sound insulation, in a practical, easy to manage, modular fashion. The method provides for the packaging of insulation material to be contained in an air-tight but moisture permeable material that traps the particulates but not moisture vapor. The insulation material may also be blended with other materials to adjust the product's resistance to thermal or sound conductivity, cost, and in order to prevent leakage in the event of puncture.
