Method for Top Sealing a Cardboard Tray Lined with a Plastic Foil and Cardboard Tray Therefor
The invention relates to a method for top sealing a cardboard tray lined with a plastic foil. The method includes the steps of providing a cardboard tray having a bottom, upstanding walls arranged along the periphery of the bottom and a horizontal flange arranged along the upper edges of the upstanding walls, wherein the inside of the cardboard tray is lined with a plast foil, which plastic foil extends at least onto the horizontal flange; arranging the cardboard tray in a lower sealing tool member having a compressible support edge, wherein at least the horizontal flange is supported by the compressible support edge of the lower sealing tool member; arranging a cover foil over the cardboard tray arranged in the lower sealing tool member to cover the opening of the tray defined by the upper edges of the upstanding walls; and pressing a heated upper sealing tool member onto the lower sealing tool member, wherein the cover foil, the plastic foil liner and the horizontal flange are pressed together to seal the cover foil onto the plastic foil liner along the horizontal flange. The overlapping area of the plastic foil liner, the cover foil, and the compressible support edge extends at least partially outside of the area of the horizontal flange.
WAX ALTERNATIVE WATER AND MOISTURE RESISTANT CORRUGATED BOARD
A recyclable corrugated board can include a first outer layer, a second outer layer, and a non-wicking medium attached to and disposed between the first outer layer and the second outer layer. The non-wicking medium is not impregnated and is not coated. The non-wicking medium can be corrugated paper, for example.
FOLDABLE PITFALL BEDBUG TRAP
A trap for certain insect pests may be configured to be particularly suitable for bedbugs and take the form of a foldable pitfall bedbug trap. The pitfall trap walls extend vertically upwardly at an angle and are sufficiently rough to permit bedbugs to climb to an upper edge of the trap, whereas the inner surfaces of the pitfall trap walls have been treated with a smooth material, such as being laminated, causing bedbugs at the upper edge to fall upon initiating contact with the inner pitfall walls and their smooth characteristics. The resultant foldable pitfall bedbug trap is relatively inexpensive to produce and easily user-deployable.
A PROCESS FOR FORMING A CONTAINER
A process for forming a container from a blank, the process comprising the steps of: thermally inducing one or more fold lines on at least one surface of a container blank fabricated from a thermal insulation sheet material, wherein the blank comprises: a first panel portion; a second panel portion located adjacent the first panel portion and sharing a first common edge therewith; and a third panel portion located adjacent the second panel portion and sharing a second common edge therewith, the second common edge being substantially parallel to the first common edge, wherein the first panel portion and the third panel portion are each associated with a pair of flap members adapted for folding movement relative to the respective first and third panel portions such that, when assembled, each of the flap members overlies an edge of the second panel portion substantially perpendicular to the first common edge and the second common edge, folding the first panel portion of the container blank along a first fold line, wherein when folded, the first panel portion is substantially perpendicular to the second panel portion of the container blank; folding the third panel portion of the container blank along a second fold line, wherein when folded, the third panel portion is substantially perpendicular to the second panel portion and substantially parallel to the first panel portion; sealing a portion of each of the pair of flap members of the first panel portion to a portion of each of the pair of flap members of the third panel portion to form a side seam joint; and sealing a portion of the first panel portion adjacent the side seam joint and a portion of the third panel portion adjacent the side seam joint to an edge of the second panel portion to form a bottom seam joint.
CONTAINER AND METHOD OF MANUFACTURING THE SAME
Various embodiments are directed to repulpable and recyclable container comprising an outer liner, an inner liner, a sidewall medium arranged between the outer liner and the inner liner, the sidewall medium being defined at least in part by a sidewall flute, and one or more coating layers adhered to one or more of a first outer liner surface, a second outer liner surface, a first inner liner surface, and a second inner liner surface; wherein the container is configured such that the flute is adhered to the outer liner and the inner liner via at least one volume of adhesive configured to directly engage at least a portion of the one or more coating layers. Various embodiments are directed to a container manufacturing system configured to produce a repulpable and recyclable container. Various embodiments are directed to a method of manufacturing a repulpable and recyclable container.
Blank for forming a container
A blank has an upper surface and a reverse surface. The upper surface is printed in a conventional manner and includes outer side panels and inner side panels. Attachment regions are provided on the inner side panels of the outer surface, and corresponding attachment regions are provided on the outer side panels of the reverse surface. During assembly the respective attachment regions are arranged to face one another and an adhesive is provided therebetween. In the present method, the attachment regions of the upper surface initially have a surface tension in the range from around 34 dynes/cm to 60 dynes/cm before the upper surface is printed. The attachment regions are treated in order to maintain a surface tension in the desired range of 34 dynes/cm to 60 dynes/cm, following printing and before any adhesive is applied. This is achieved by applying an auxiliary printing medium to the attachment regions.
LINE FOR THE PRODUCTION OF COVERED CARDBOARD BOXES
A line and method for the production of covered cardboard boxes are disclosed. The line includes a conveyor unit including a belt and a conveyor actuator that drives the belt intermittently in an alternating sequence of movements and stops. A feed unit individually feeds covering blanks from a reservoir to the conveyor unit in a sequence of feed instants. An erecting machine folds box blanks into corresponding boxes. A positioner individually positions the boxes from the erecting machine, in alignment on corresponding covering blanks disposed on the belt of the conveyor unit. A gluer spreads glue on one face of the covering blanks. A covering machine folds the covering blanks into contact with their respective boxes to cover the boxes. A control unit connected to the feed unit adjustably sets a phase displacement of the feed instants relative to the sequence of stops of the belt.
