A method of producing a gable-top paper or paper-board based packaging container is disclosed, the packaging container having a plurality of top-closure sub-panels, including a top-closure sub-panel (132) configured to form a pouring spout of the packaging container when the packaging container is in an open position, the top-closure sub-panel being configured to form a pouring spout comprising top-fin panel sections (182a, 182b) being at least partially hot-sealed to each other prior to a first opening of the packaging container, the top-fin panel sections abutting one another in a contact region when the packaging container is in a closed position. The method comprises the steps of: producing a blank (100) from a laminate packaging material having an outside heat sealable layer; and treating the outside heat sealable layer in a sub-region (192a, 192b) of at least one of said top-fin panel sections (182a, 182b) reducing or eliminating the heat-sealing capacity of the outside heat sealable layer in the sub-region. A related blank and a packaging container produced from such a blank is also disclosed.

Disclosed is a thermal insulating shipping container with a five-sided box wherein a bottom and four sides all have an inner layer of corrugated polymer, a middle layer of shrink-wrapped panels with each panel being a vacuum panel, and an outer layer of corrugated polymer. The container is formed by inserting polyurethane liquid into the gaps and spaces between the shrink-wrapped panels and the inner and outer layers and foaming the polyurethane liquid and allowing it to harden. Weather stripping may be adhered to the edges of the container which are opposite to the bottom of the container.

A moisture resistant poultry box having a composite structure with a fluted paper medium, a top backing board assembly secured to one side of the fluted medium and a bottom backing board assembly secured to the other side of the fluted medium. The backing board assemblies and the fluted medium are impregnated with a hydrogenated triglyceride, and each backing board assembly has PET film glued thereto covering an outside surface to provide moisture resistant recyclable poultry box so that it has a Cobb value ranging between about 0 to about 1.

A coated paperboard container includes an inner paperboard substrate, an outer paperboard substrate, a first aqueous barrier coating located on the inner paperboard substrate, and a second aqueous barrier coating located on the outer paperboard substrate. The inner paperboard substrate and the outer paperboard substrate are coupled with an adhesive. The first aqueous barrier coating and the second aqueous barrier coating include a pigment and a binder and the first aqueous barrier coating is heat sealable.

Methods for securing a shrinkable film to a paperboard substrate and methods for making paperboard containers therefrom. In one or more embodiments, a band of adhesive may be applied about a perimeter of a paperboard substrate having a first edge and a second edge opposed to one another and a third edge and a fourth edge opposed to one another. The band of adhesive may surround a first area that is substantially free from the adhesive. A second area that may be substantially free from the adhesive may be located along a portion of the third edge, between the first and second edges. The first area and the second area may be separated by the band of adhesive. A shrinkable film may be secured to the paperboard substrate with the adhesive to produce a paperboard blank. The third edge and the fourth edge may be overlapped to form a sidewall. A bottom panel may be secured to the sidewall at or adjacent the second edge. The first edge may be curled to form a brim.

The invention relates to the field of cups, bowls and containers, particularly beverage cups, and to the production of cups, bowls and containers. According to the invention, the cups, bowls and containers comprise, in a first variant, a first layer (5) made of cellulose hydrate, also known as cellophane, or cellulose hydrate which is coated with a primer material (4). In addition, the cups, bowls and containers can comprise a second layer (3), made of paperboard or fibre/cellulose-starch mix, for example. In a second variant, the cups, bowls and containers according to the invention comprise a first layer made of natural rubber or plant-based wax and a second layer made of cellulose hydrate, paperboard or fibre/cellulose-starch mix. By using exclusively biodegradable materials, the present invention can provide completely biodegradable/compostable cups, bowls and containers. The invention also relates to a method for producing such cups, bowls and containers. In addition, the present invention also comprises the production of lids made of the aforementioned materials and the provision of cups, bowls and containers having such lids.

Processes, assemblies, and sleeve blanks for forming a two-piece paper container are provided in which the sleeve blank includes an adhesive printed onto the sleeve blank while the sleeve blank is still part of the paper web. The adhesive can optionally be printed onto the sleeve blank in-line with printing a graphic on the sleeve blank prior to providing the sleeve blank to a container forming machine that wraps and seals the sleeve blank to a bottom blank.

A method of manufacturing a coated paperboard container includes: providing a coated paperboard bottom blank, the coated paperboard bottom blank comprising a paperboard substrate and a first barrier coating layer on a first outermost surface of the paperboard substrate; heating the coated paperboard bottom blank; shaping the heated coated paperboard bottom blank, thereby forming a peripheral skirt portion about a periphery of a bottom wall portion of the coated paperboard bottom blank; and sealing a coated paperboard sidewall to the first barrier coating layer of the peripheral skirt portion.

A method is proposed for manufacturing a cup intended for containing a food beverage. The method includes cutting out at least one sheet of coated paperboard to form a side wall and a bottom and joining the sheets thus cut out by heat-sealing to form the cup. The at least one paperboard sheet is coated on at least the interior side of the cup with a biodegradable varnish according to a coating/spreading technique. In this way, the cup is easy to manufacture, and complies with environmental standards in being easy to recycle and compost, even at home. Thus, the biodegradable varnish does not disturb or pollute the operation of the pulper used in the paper industry.
