Enhanced Adhesion Of Polyethylene Terephthalate To Paperboard

View page
US Patent:
7507473, Mar 24, 2009
Filed:
Aug 15, 2007
Appl. No.:
11/893384
Inventors:
Ladislav Bednarik - Loveland OH, US
Vivek Rohatgi - Owasso OK, US
David V Reed - Blanchester OH, US
Assignee:
International Paper Company - Loveland OH
International Classification:
B32B 27/10
B32B 27/16
B32B 27/30
B32B 27/36
B32B 37/15
US Classification:
428342, 428341, 428219, 428340, 428480, 428481, 428483, 428507, 428511, 428512, 428513, 428514, 4285375, 4285377, 427223, 427299, 427322, 427324, 427326, 427402, 4274071, 427411
Abstract:
A unique primer emulsion chemistry yields excellent adhesion of polyethylene terephthalate (PET)resin to clay coated paperboard (with high starch content) at reduced coatweights of the primer emulsion and the resin as compared to other primer and tie-resin chemistries currently employed for moisture barrier applications. A primer used for adhesion enhancement is an ammonium catalyzed, self-crosslinking copolymer of ethylene-vinyl acetate with N-methylol acryl amide functional groups attached to a polymer backbone. Use of the primer in amounts up to about 0. 5 pounds per ream permits PET coatweights of as low as 10-12 lbs per ream and lower for some applications.

Maged Botros - West Chester OH, US
Richard Previty - Milford OH, US
Gregory Castle - Wilder KY, US
International Classification:
A01N001/00
B29C047/90

Paper Based Retortable Can And Method For Making Same

View page
US Patent:
20040052987, Mar 18, 2004
Filed:
May 9, 2003
Appl. No.:
10/434566
Inventors:
Shankara Shetty - Milford OH, US
Thomas Fu - Milford OH, US
Vivek Rohatgi - Loveland OH, US
Ashok Adur - Cincinnati OH, US
International Classification:
B32B001/08
US Classification:
428/034200, 428/036910, 156/203000
Abstract:
An improved retortable can is provided in which a primary structural element is a layer of paper or paperboard, which is laminated with a shielding layer on each side of the paper or paperboard core, and at least one barrier layer. The shielding layer is resistant to heat and moisture, and the barrier layer substantially reduces the transmission rate of oxygen, moisture, and flavor. A method for manufacturing the paper-based retortable can is also provided, which converts a web of the laminate material into tubes, either in a spiral-wrap (or a convolute) shape or a cylindrical shape that uses a side seal. An additional method for manufacturing paper-based retortable cans is provided in which two separate “half-structures” of laminate are joined in a spiral-wrap manufacturing step to form a single laminated structure with two paper/paperboard interior layers having an adhesive therebetween.

Oil And Moisture Absorbent Material And Food Package

View page
US Patent:
20040156957, Aug 12, 2004
Filed:
Feb 12, 2003
Appl. No.:
10/365303
Inventors:
Sandeep Kulkarni - Morrow OH, US
Ladislav Bednarik - Loveland OH, US
Keith Shih - Loveland OH, US
Richard Previty - Milford OH, US
I. Sand - Loveland OH, US
Vivek Rohatgi - Loveland OH, US
Richard Tedford - Loveland OH, US
John Tonelli - Batavia OH, US
International Classification:
A23B004/00
US Classification:
426/127000
Abstract:
A oil and moisture absorbent material suitable for use in food packages and a food package made of such material. The material comprises an oil and moisture absorbent layer covered by an oil and moisture repellent substance that has a multiplicity of perforations or which is applied in a pattern so that oil and moisture can pass through. Alternatively, the oil and moisture absorbent layer may be covered by an oil and moisture permeable substance. The oil and moisture absorbent layer may have indentations and additives that improve its oil and moisture absorbency. The oil and moisture absorbent layer may be made of a paperboard that is manufactured using a reduced level of calendering and having a reduced amount of sizing applied.

Abstract:
The present techniques provide an extruder screw comprising a high shear melting and mixing zone starting a distance away from an entry point of the screw corresponding to 35%-50% of the overall screw L/D. The extruder screw may also include elements capable of increasing a degree of fill of the high shear melting and mixing zone. In accordance with present techniques, the extruder screw is configured to blend two or more polyolefin polymers having greater than about a 200,000 difference in weight-average molecular weight in a single extrusion step. The extruder screw of the present techniques may be used in a single screw or twin screw extruder, and may be incorporated into a polyolefin production plant for producing multi-modal resins.
