Description

Изобретение относится к способам запечатывания запыленных продуктом горловин пакетов из термопластичной пленки, например, полиэтиленовой, методом сварки и может быть использован в упаковочных операциях в различных отраслях промышленности.The invention relates to methods of sealing the product’s dust-coated necks of thermoplastic film packages, for example, polyethylene, by welding, and can be used in packaging operations in various industries.

Цель изобретения — повышение качества запечатывания за счет обеспечения сварки краев пакета по незапыленным сторонам.The purpose of the invention is to improve the quality of sealing by ensuring the welding of the edges of the package on the non-dusty sides.

На чертеже изображен пакет в момент запечатывания горловины сваркой нагретыми элементами, разрез.The drawing shows the package at the time of sealing the neck by welding heated elements, the cut.

Способ запечатывания термопластичных пакетов осуществляется следующим образом.The method of sealing thermoplastic bags as follows.

После заполнения пакета 1 продуктом 2 5 кромки 3 горловины пакета накладывают друг на друга и загибают вовнутрь пакета на 180° по всему периметру. В зоне, подлежащей сварке, сжимают горловину пакета 1 нагретыми элементами 4 до образования сварного соединения между сво1° бодными от пыли сопрягаемыми поверхностями пленочного материала пакета. Однако нагрев свариваемого материала может быть осуществлен также, например, газовым теплоносителем или с помощью теплового излучения.After filling the bag 1 with the product 2 5, the edges 3 of the neck of the bag are overlapped and bent to the inside of the bag by 180 ° around the entire perimeter. In the area to be welded, compress the neck of the package 1 with the heated elements 4 until a welded joint is formed between its mating dust surfaces by the mating surfaces of the film material of the package. However, heating of the material being welded can also be carried out, for example, by a gas-cooled or by means of thermal radiation.
