SUBSTANCE: invention relates to the field of vacuum packaging technology and concerns a vacuum tight package with an easy-to-open/resealable bottom leaf. Package contains the bottom leaf, the product and the top leaf. Bottom leaf contains a laminate with a die-cut and a label applied to the die-cut and adhered to the laminate in such a way that when the label is peeled off, a part of the laminate peels off, opening the package, while the packaging can be re-closed by returning the label to its original position on the layered material. Method of manufacturing easy-opening/re-closing vacuum tightly fitting package is also described, comprising forming a bottom leaf; product placement on the bottom leaf; forming a thermoformed top leaf and promoting the product through the vacuum packaging steps into a tightly fitting film to form a package whose top leaf touches and conforms to the shape of at least part of the product; while the lower leaf contains a layered material with profiled carving and a label superimposed on the profiled carving and coupled with the layered material.

EFFECT: invention provides the creation of packaging that can be used without modifying the packaging equipment of the food packaging company, ensuring easy opening and re-sealing of the packaging.
