Reclosable packaging using low-tack adhesive fastener

FIELD: packaging industry.

SUBSTANCE: flexible film package with reclosable fastener on adhesive base comprises a flexible film substrate, from which is formed a plurality of package walls, forming a sealed inner cavity for arrangement of a product; plurality of walls, including at least two opposite flexible walls; package mouth, initially sealed, provide access to inner cavity; low tack pressure sensitive adhesive (LTPSA) layer on each external surface of parallel walls, wherein size and arrangement of LTPSA layers is set so, that they are located opposite each other in multiple positions when reclosing package and provide gradual reduction of size of inner cavity with extraction of product,and where adhesion strength of LTPSA and flexible film substrate is greater than adhesion between portions of LTPSA.

EFFECT: mouth can be formed by peel seal or preset area of weakening strength.

SUBSTANCE: tube case of a flat sheet blank made of resilient dense material such as plastic sheet contains slots with figured locks positioned opposite the slots and designed so that to enable fixation in the slots. The tube case is equipped with butt-end closing means. The sheet blank is rectangular shaped; the tube case has a drop-shaped cross section including a chute-shaped area with the walls conjugated with the rectangular flat areas. On one side of the blank there is a bending flap separated from the other surface of the sheet blank with at least one line off the blank material attenuation parallel to the shorter sides. There are at least two lines of the blank material attenuation (parallel to the shorter sides) positioned at equal distance from the crosswise symmetry axis of the remaining blank surface. The tube case is equipped with at least one butt-end closing means formed by a longitudinal slot oriented along the longer side of the blank connecting the centrally positioned blank material attenuation lines turned towards the shorter sides.

EFFECT: minimisation of document sheet deformation during storage.

SUBSTANCE: cardboard for liquids contains fibrous base on which at least from one side a layer of polymer coating is applied. And the fibrous base contains at least 1.3 kg of hydrophobic adhesive agent comprising alkyl ketene dimer, per 1 ton of dry matter, and at least 1.0 kg of water-resistant adhesive agent per 1 ton of dry matter, the density of the fibrous base is 630-800 kg/m3, the amount of thermosealing polymer in the coating layer is higher than the amount of shagginess of uncovered fibrous base, measured at the Bristowe's wheel and/or comprises at least 14 g/m2, the pH value of the cardboard aqueous extract measured by the method of ISO 6588, is higher than 7.0. The drinking glass made of such cardboard is resistant to 30 wt % solution of ethanol at a temperature of 23C for at least 1 hour.

EFFECT: group of inventions provides resistance of cardboard to solvents by reduction of absorption capacity of the cardboard through the rough edge.

SUBSTANCE: present invention relates to container made from cardboard fibre-based and containing shell and bottom. Bottom comprises coated with polymer cardboard and is connected to shell by heat sealing. Shell includes fibre-based cardboard, which taped to have absorption at Cobb below 100 g/m2 for one hour measured according to ISO 535, wherein shell is uncovered by polymer coating and is formed by way of its two edges to form lateral seam.

EFFECT: container according to invention is resistant to fluid and/or fat, its manufacturing is economically beneficial and it can be processed for reuse.
