Abstract
A dual chamber sachet with a dispensing outlet can be made in a form/fill sequence by attaching the dispensing outlet to the film that is to form the chamber divider wall followed by attaching films that are to form the outer walls of the sachet to the dispensing outlet. The upper and side lateral edges of the sachet then are sealed together to produce a sachet with an open bottom end. The sachet can be produced from three film sources, two film sources with the outer walls being formed from a single film, or from a single film formed into a W-shape. The sachet preferably is filled through the open bottom end and the bottom end then sealed. However the sachet can be top filled through the nozzle. The sachets then are severed one from the other by cutting along a lateral seal and packed into a carton, or preformatted along a lateral seal and cut to produce a string of a set number of sachets. The sachets can have a single use dispensing outlet or a reclosable dispensing outlet. Larger sachets will have a reclosable dispensing outlet.
