DETACHABLE SEALING MATERIAL FOR PACKAGING, COMPRISING MIXTURES OF FILLED THERMOPLASTICS Russian patent published in 2016 - IPC B32B27/20 B32B7/06 B65D30/02 B65D77/10 

FIELD: packaging industry.

SUBSTANCE: package comprises a part with the separable sealed seam comprising a first sealing layer and a second sealing layer. The first sealing layer interacts with the second sealing layer to form a separable sealed seam. The first sealing layer comprises a thermoplastic polymer or a mixture of thermoplastic polymers, organoclay dispersed the thermoplastic polymer, and an additional inorganic additive such as calcium carbonate, dispersed in the thermoplastic polymer.

EFFECT: creation of a package with the separable sealed seam, which has a high specific thermal conductivity, an excellent degree of sealing and about the same characteristics in a wide temperature range of heat sealing, without the loss of desired properties with aging of the seam.
