A coating system for coating a web of paper includes spaced apart support rollers, a guide roller, a tension roller, a motor, a dispenser, and a control system. The support rollers support respective spools of paper. The guide roller is configured for guiding the paper along a path between the spools of paper. The tension roller is positioned along the path and is configured to engage the paper. The motor is operable to rotate the support rollers and/or the tension roller. The dispenser is fixed proximal to the path and is operable to guide liquid coating onto the paper located on the path. The control system is in communication with the motor and is configured to direct the motor to cause the paper to shift in either direction along the path between the spools.

A metalized powder painted color sample for facilitating selection of a powder paint, the powder paint being applicable to a base material, is described. The metalized powder painted color sample includes a paper substrate sheet including a first side, a metallic layer bonded to the first side of the paper substrate sheet, and a powder paint layer bonded to the metallic layer. The metallic layer includes aluminum and has a thickness of between 15 nanometers and 50 nanometers. The powder paint layer includes a cured polymer powder paint and having a thickness of between 20 micrometers and 140 micrometers. In some embodiments, at least a portion of the metalized powder painted color sample has a same color and a same texture as the base material when the powder paint has been applied to the base material.

The invention discloses a paperboard for packaging of a heat-sealable packaging material comprising: a paperboard substrate comprising a first and a second side, a first and an optional second dispersion coating layer on the first side, which first and optional second dispersion coating layer provides a barrier against at least one of liquid, moisture, grease and gas, an extrusion coated barrier layer comprising a polyolefin, wherein the first and optional second dispersion coating layer is applied between the paperboard substrate and the extrusion coated barrier layer, and wherein the coat weight of the extrusion coated barrier layer is less than 15 gsm. The packaging material according of the invention minimizes the amount of plastic coating, but still provides the needed barrier properties for the packaging of food and/or liquid. The packaging material has especially been shown to provide a longer shelf life for food items packed in a packaging made from the material. Especially, the packaging material provides gas-, liquid and/or grease barrier properties. Although the packaging material comprises such low amount of extruded thermoplastic polymers, the material is readily heat-sealable.

The present invention provides water-based coatings that provide liquid resistance when applied to various substrates. The coatings are particularly suitable for cellulosic substrates such as paper or paper board. In addition to liquid resistance, the coatings have good heat sealability, and are resistant to roll blocking. Preferably, the coatings are recyclable and/or repulpable with the substrates to which they are applied. The coating compositions comprise one or more polymer binders, and one or more particles. Preferably, at least one polymer binder has a glass transition temperature (Tg) less than 10 C. Preferably, at least one polymer binder has a heat seal onset temperature of less than 200 C. Preferably, at least one particle has a mean particle size greater than 4 m. It is also preferable that the particles have a melting point greater than 60 C.

The methods and compositions of the present disclosure pertain to a package blank, having one or more fiber containing layers and having die cut edges. The methods and compositions provide multi-surface barrier protection for alcohol and liquid permeation along multiple axis of the packaging blank. The packaging blank can have many exposed surfaces depending upon how the blank is designed and cut from a sheet or roll. The methods and compositions provide permeation protection for the entire package, including the flat surfaces and the cut edge surfaces that make liquid contact, particularly alcohol, which are found enclosed or within the finished packaging structure. This is accomplished by both coating the blanks and structural methods of cutting, die cutting, and folding techniques.
