ELASTIC MATERIALS FOR ELASTIC CONTAINERS Russian patent published in 2016 - IPC B32B27/08 B32B27/30 

FIELD: chemistry.

SUBSTANCE: invention relates to polymer materials used for making containers for fluids, and concerns elastic materials for elastic containers. Flexible material for a flexible container comprises a first laminate comprising in following sequence: a first sealing layer, which is a linear low density polyethylene, which forms outer layer of first laminate; bonding layer; reinforcing layer, which is a nylon; gas-impermeable layer, which is an ethylene-vinyl alcohol; second reinforcing layer, which is a nylon; second bonding layer; sealing layer, which is a linear low density polyethylene, which forms outer layer of first laminate; second laminate containing in following sequence: a third sealing layer which forms outer layer of second laminate; second gas-impermeable layer, which is an ethylene-vinyl alcohol; printing layer, which includes surface to receive and retain ink and which forms outer layer of second laminate; wherein part of third sealing layer is connected to part of second sealing layer so that connected parts form at least one junction, with bonding strength from 20 N/m to 10,000 N/m, layers of first laminate are characterised by lamination strength between all adjacent layers from 2 N/m to 10,000 N/m, and layers of second laminate are characterised by lamination strength between all adjacent layers from 2 N/m to 10,000 N/m.

EFFECT: invention enables to create containers for fluids, having manufacturability and which are easy to use.
