Appl. No.:

09/441742

Inventors:

Henry G. Schirmer - Spartanburg SC

Assignee:

BBS Corporation - Spartanburg SC

International Classification:

B29C 4706

US Classification:

428 341, 4251331, 425192 R, 425380, 220 622, 220 2383, 220844, 215 121, 215370, 264 96, 264171

Abstract:

A coextrusion die includes a plurality of annular cells stacked on top of each other. Each annular cell includes a plurality of openings aligned with openings in the adjacent cell, thus forming multiple streams. Plastic melt may be supplied to the die coplanarly. Stacks of annular disks may be joined to form the annular cells through which plastic melt can be axially directed.

B32B 3/00

US Classification:

428220, 4283044, 4283155, 428141

Abstract:

Cellular thin films include a first side separated from a second side, the separation of which defines the thickness of the thin film; at least one layer of a polymeric material arranged along the thickness of the thin film, wherein the polymeric material includes cells and the first and second sides of the thin film have exterior surfaces that have substantially the same thickness as the interior walls forming the cells. The surfaces of the thin films have bumps caused by the cells. The thin exterior surfaces of the thin films is advantageous to allow the films to be flexible.

Appl. No.:

13/752458

Inventors:

HENRY G. SCHIRMER - Spartanburg SC, US

Assignee:

BBS Corporation - Spartanburg SC

International Classification:

B29C 47/06

US Classification:

4251311

Abstract:

A layer sequence repeater module for a co-extrusion die includes a cell formed of a plurality of thin annular disks stacked on top of each other in an axial direction of the co-extrusion die. Each disk includes a plurality of openings aligned with openings in the adjacent disks, thus forming multiple inner and outer melt passages. At least one of the layer sequence repeater module includes at least one first cap disk, at least one second cap disk, at least one distribution disk, at least one repeater disk and at least one spreader disk. The layer sequence repeater module may be a separately assembled and individually removable module of the co-extrusion die. Alternatively or additionally, the layer sequence repeater module may be incorporated into a module of the co-extrusion die.

Assignee:

W. R. Grace & Co.-Conn. - Duncan SC

International Classification:

B32B 3128

US Classification:

1562726

Abstract:

Thermoformable barrier sheet includes a barrier film having low oxygen transmission, and a thermoformable plastic, especially a foamed or unfoamed polystyrene sheet bonded thereto. Bonding can be accomplished by corona bonding or by thermal bonding.

Filed:

Mar 6, 1986

Appl. No.:

7/316588

Inventors:

Henry G. Schirmer - Spartanburg SC

Assignee:

W. R. Grace & Co.-Conn. - Duncan SC

International Classification:

B65D 3010

US Classification:

383119

Abstract:

A seamless, bone puncture resistant bag is provided that representatively includes a length of lay-flat seamless tubular film folded to a double lay-flat configuration and having all adjacent film surfaces interfacially bonded, respectively, except at one outermost interface. The configuration thus forms a seamless envelope with one face thickened integrally to triple thickness. In a less preferred mode, a similarly reinforced bag is provided but which has either an end-seal or side-seals. Associated methods for making such bags are also provided.

US Classification:

428 367

Abstract:

A multilayer laminated film useful in chub packaging comprises a core film comprising a biaxially oriented film, and an outer hot blown film bonded to each of the opposing surfaces of the core layer, at least one of the films including a layer of an oxygen barrier polymeric material.

International Classification:

B65D 6504
B65D 8500

US Classification:

206471

Abstract:

A package and a method of producing a package by forming a pocket in the central portion of a sheet of wrapping material, preferably a thermoplastic film, placing a product within the pocket, folding the flat portions of the film into face-to-face contact and bonding the flat portions together. The package can also be evacuated and hermetically sealed. If the film has been oriented, the pocket may be heat shrunk.
