A package includes a stack of hinged trays for holding media discs, having a flexible hinge member affixed to the hinge edges of the trays, mounted in a protective container having a base, a spine and a cover. The bottom tray in the stack is mounted in the base for pivotal movement about the tray edge opposite the hinge edge, whereby, as trays are pivoted about the flexible hinge member from the stack onto a second stack, the hinge edge of the bottom tray pivots away from the base when the second stack contains at least one more tray than the original stack. Pivotal mounting is achieved by providing a slot on the bottom tray which engages slot receiving means mounted on the base.

Packaging for multiple media discs

This invention relates to a laminate substrate. An exemplary embodiment comprises a paperboard layer with a heat sealable layer secured substantially adjacent to one side of the paperboard layer. A co-extruded layer is secured substantially adjacent to the other side of the paperboard layer. The co-extruded layer has five layers: a heat sealable layer secured to the paperboard layer, a first tie layer secured adjacent to the heat sealable layer, a semi-crystalline nylon layer secured adjacent to the first tie layer, a second tie layer secured adjacent to the semi-crystalline nylon layer, and a heat sealable layer secured adjacent to the second tie layer. A fourth heat sealable layer is secured adjacent to the co-extruded layer.

Laminate substrate with oxygen barrier properties

This invention relates to paperboard composite structures with a glass-coated film. Such structures of this type, generally, improve the shelf life of refrigerated and other oxygen-sensitive products and provide a barrier to flavors and fragrances to maintain product quality.

This invention relates to paperboard materials for carrying static cling vinyl products for transport to end users. Such structures of this type, generally, provide good adhesion for the static cling vinyl product, but allow the vinyl product to be peeled off easily.

Paperboard carrier for static cling vinyl products

This invention relates to paperboard laminates for pharmaceutical blister packaging. Such structures of this type, generally, employ a hot melt adhesive and calcium carbonate (CaCO.sub.3) blend which is capable of sealing to polytrichlorofluoroethylene (Aclar.RTM.). Aclar.RTM. film is commonly used for high moisture barrier packaging in pharmaceutical applications.

This invention relates to a method and apparatus for heat sealing polymer coated paperboard substrates with light energy. Such structures of this type, generally, use lasers which allow a very accurate placement of the sealing energy and a controllable energy level.

Method for heat sealing paperboard substrates using a uniform energy

This invention relates to paperboard and plastic composite package structures that combine an intricate thermoformed shell with a paperboard base or cover. Such structures of this type, generally, provide a lightweight package with a good printing surface on the outside of the package.

This invention relates to making paperboard and plastic composite package structures that combine an intricate thermoformed shell with a paperboard base or cover. Such structures of this type, generally, provide a lightweight package with a good printing surface on the outside of the package.

This invention relates to a method and apparatus for heat sealing polymer coated paperboard substrates using a uniform energy distributed light energy beam. Such structures of this type, generally, use lasers which allow a very accurate placement of the sealing energy and a controllable energy level.

A method is disclosed for producing, in a continuous throughput, high quality paper from recycled waste paper utilizing high consistency, low shear pulping, followed by a series of cleaning steps to produce a wet, friable pulp which is digested and optionally bleached. The resulting pulp can be run on a paper machine alone or blended with virgin pulp to produce a paper containing at least 5 by weight recycled paper with less than 20 ppm per unit area solid non-fibrous contaminants larger than 0.3 mm.sup.2, and which may be blade coated on a high speed paper machine. A blade coated paper produced by the method is disclosed.

The resulting pulp can be run on a paper machine alone or blended with virgin pulp to produce a paper containing at least 5% by weight recycled paper with less than 20 ppm per unit area solid non-fibrous contaminants larger than 0.3 mm.sup.2, and which may be blade coated on a high speed paper machine. The pulp and paper produced by the methods are also disclosed.

A method is disclosed for producing, in a continuous throughput, high quality paper from recycled waste paper utilizing high consistency, low shear pulping, followed by a series of cleaning steps to produce a wet, friable pulp which is digested and optionally bleached. The resulting pulp can be run on a paper machine alone or blended with virgin pulp to produce a paper containing at least 10% by weight recycled paper with less than 20 ppm per unit area solid non-fibrous contaminants larger than 0.3 mm.sup.2, and which may be blade coated on a high speed paper machine.
