A chill roll for cooling a web is provided and includes a cylindrical outer roll having an inner and an outer surface, the inner surface of the outer roll having circumferential projections spaced at intervals along its length forming circumferential channels therebetween. The chill roll further has a cylindrical inner roll having an inner and an outer surface, and a diameter less than a diameter of the outer cylindrical roll and defining an annular space between the outer surface of the cylindrical inner roll and the inner surface of the cylindrical outer roll, allowing a coolant material to flow into and out of the circumferential channels and to contact the inner surface of the cylindrical outer roll to uniformly cool the outer surface of the cylindrical outer roll. A cylindrical middle shell is disposed between the inner surface of the cylindrical outer roll and the outer surface of the cylindrical inner roll allowing passage of the coolant material from the cylindrical inner roll to be transferred into and out of the circumferential channels through openings disposed along the cylindrical middle shell.

High production chill roll

A non-foil composite structure is provided having a substantial barrier to the loss of moisture, oxygen, and organic vapor and which is easily sealable with a shelf-life to at least one year for food and non-food products during dry shelf storage, and which is environmentally friendly. The laminate may have, from the outer atmosphere exposed surface to the inner surface contacting the contents of the container; a first exterior layer of a low density polyethylene polymer; a paperboard substrate; a first interior layer laminate coating of nylon with a tie layer; a second interior layer of low density polyethylene polymer; a third interior layer of high density polyethylene polymer; and an innermost and product contacting layer of low density polyethylene polymer.

Non-foil polymer coated carton for packaging food and non-food products

A multilayer non-foil barrier bag or liner constructed to house hazardous chemicals such as pesticides and herbicides. The unique bags or liners maintain the efficacy of the active ingredient of the herbicide or pesticide over extended periods of time.

Non-metallic bag or liner for hazardous chemical containment

The present invention relates to a novel coextrusion coating for paper or paperboard substrates. The coextrusion includes a nonpolar polymer layer and a thin exterior skin layer made up of a nonpolar polymer and a polar copolymer. The addition of the polar polymer improves long term treatment level retention which improves long term wettability for printing and gluing adhesion during package or carton formation.

Paperboard laminates having polar copolymer/nonpolar polymer blend

The present invention relates to an improved container for food and non-food products. The container utilizes a novel combination of materials to overcome polymer odor-emission problems that detract from the packaged product. The novel material structure includes a polymer flavor/fragrance concentrate which imparts an enhanced fragrance to the product when the container is opened, increasing consumer appeal.

Flavor/fragrance enhanced composite structures

The present invention relates to an improved container for food and non-food products. The container utilizes a novel paperboard barrier laminate structure which maintains an isolated gas environment in the container. The laminate makes use of a high strength, heat-resistant and caulking polymer layers which prevent pinholes, cuts, or cracking of the barrier layers during blank conversion, package formation, and package distribution. In addition, the novel polymer resin layers act to caulk the seams and channels present in the carton providing a sealed leak free container.

Oxygen impermeable leak free container

The present invention relates to an improved container for food and non-food products. The container utilizes a novel paperboard barrier laminate structure which maintains an isolated gas environment in the container. The laminate makes use of high strength, heat-resistant and caulking polymer layers which prevent pinholes, cuts, or cracking of the barrier layers during blank conversion, package formation, and package distribution. In addition, the novel polymer resin layers act to caulk the seams and channels present in the carton providing a sealed leak free container.

The present invention relates to an improved composite barrier laminate for an improved container for citrus juices and other liquids. The container utilizes a paperboard barrier laminate for the containment of essential oils and the prevention of losses of vitamin C. The laminate makes use of an inner barrier layer of a heat-sealable oxygen and flavor oil barrier material to enhance the barrier properties of the laminate as well as an extremely thin low density polyethylene food contact layer to provide a resultant secure homogenous non-polar heat seal.

Composite polyethylene barrier structure

The present invention relates to an improved container for food and non-food products. The container utilizes a novel paperboard barrier laminate structure which maintains an isolated gas environment in the container. The laminate makes use of high strength, heat-resistant and caulking polymer layers which prevent pinholes, cuts or cracking of the barrier layers during blank conversion, package formation, and package distribution. In addition, the novel polymer resin layers act to caulk the seams and channels present in the carton providing a sealed leak free container.

The present invention relates to an improved container for citrus juice and other liquids. The container utilizes a paperboard barrier laminate for the containment of essential oils and the prevention of losses of Vitamin C. Also disclosed is a process of making the laminate. The laminate makes use of a layer of a heat-sealable ethylene vinyl alcohol copolymer to enhance the barrier properties of the laminate.
