HEAT-SHRINKING PACKING SYSTEM AND METHOD Russian patent published in 2015 - IPC B65B53/02 B65C1/02 B65C3/00 

FIELD: transport; packaging.

SUBSTANCE: group of inventions relates to packing systems including a heat-shrinking container with a flexible wall or cover and a label applied to them. A method for packaging and application of the label onto an item involves production of a material subject to shrinkage, production of the label subject to shrinkage, application of the label onto the material, laying of the packed item into the material with the label and further shrinkage of the material. As per another version, the method for packaging and application of the label onto the item unlike the previous one is characterised by vacuum treatment prior to shrinkage of the inner volume of the container. The method for obtaining the packing system involves production of a container with a flexible wall, which is subject to shrinkage and has the first set of shrinkage characteristics, production of a label subject to shrinkage and having the second set of shrinkage characteristics, and approval of these sets so that after the label is fixed on the container and at their simultaneous shrinkage they are subject to shrinkage to a similar degree. The packing system itself is characterised by the fact that the first set of shrinkage characteristics of the container and the second set of shrinkage characteristics of the label are coordinated with each other. As per another version, the method for packaging and application of the label onto the item involves production of a material and label that are subject to shrinkage, application of the label onto the material, shaping of at least one label and material with change of its shape, and laying of the item being packed into the material subject to shrinkage with the label applied onto it and further shrinkage.

EFFECT: group of inventions provides quality improvement.
