Manufacturing process of flexible packaging with dispensing valve

摘要

Method for manufacturing flexible packages having a dispensing valve; which comprises: the vertical forming of a tubular body (2) by means of the vertical displacement and the longitudinal folding of a thermosealable film (1); the longitudinal sealing of two vertical ends (11, 12) of thermosealable film (1); obtaining independent flexible envelopes (3) from the tubular body (2), provided with a closed bottom and an open upper mouth (33), by means carrying out successive transversal sealings (32) and transversal cuts in said tubular body; and the horizontal displacement of the successive flexible envelopes (3) by a series of workstations in which the metering of the product to be packaged is carried out, the insertion of a dispensing valve (4) in the upper mouth (33) of the flexible envelope (3) and the sealing (34) of the upper mouth (33), fixing the dispensing valve (4).

1. Method for manufacturing flexible packages having a dispensing valve characterized in that it comprises the following steps:
a) the unwinding of a flexible thermosealable film (1); b) the vertical forming of a continuous tubular body (2) by means of the vertical displacement and the longitudinal folding of the thermosealable film (1) such that the vertical ends (11, 12) of the thermosealable film (1) are arranged opposing each other along their entire length; c) the longitudinal sealing of the two opposing vertical ends (11, 12) of the thermosealable film (1) laterally closing the tubular body (2); d) obtaining independent flexible successive envelopes from the tubular body (2), provided with a closed bottom and an open upper mouth (33), by means of carrying out successive transversal sealings (32) and transversal cuts in said tubular body; e) the horizontal displacement of the successive independent envelopes (3) by a series of work stations in which the metering (D) or filling of the product to be packaged in the interior of the successive flexible envelopes (3) is carried out, the insertion of an dispensing valve (4) in the upper mouth (33) of the flexible envelopes (3) and the sealing (34) of the upper mouth (33) of the flexible envelopes, establishing its closing and the fixing of the dispensing valve (4) to the corresponding flexible envelope (3).
