SCOPE: This Corporate General Specification outlines the general requirements for corrugated fiberboard items currently furnished to 3M Company. 1.0 GENERAL INFORMATION 1.1 Conformance All corrugated fiberboard items (boxes, interior parts, etc.) shall conform to requirements set forth in Uniform Freight Classification, NATIONAL MOTOR FREIGHT CLASSIFICATION and/or other governmental and carrier regulations as applicable, as well as to this specification. 1.2 Item Specification Item specifications will be issued for each individual item (box, creased sheet, folder, etc.). The item specification shall be considered as a supplement to this specification and shall supersede conflicting provisions herein. 1.3 Dangerous Articles Boxes and other parts furnished for packing and transportation of explosives and other hazardous materials must conform to appropriate Department of Transportation Regulations (CFR-40) and shall be so marked as required in the current Tarriff. 2.0 MATERIALS AND FABRICATIONS 2.1 New Materials All finished parts furnished under this specification must be made of mill-fresh board. No used board will be acceptable. This does not preclude the use of recycled fibers in the paperboard so long as the strength and performance of the finished part is maintained. 2.2 Substitutions No substitutions of materials from those indicated on this specification or on the item specification are allowed without written prior agreement with 3M Procurement. 2.3 Quality CGS#: 100-3M All Rights Reserved Page 1 Printed 06/23/2005

2 Materials used shall be of good commercial quality. Second Line materials will be subject to rejection by 3M with a request for replacement with acceptable material. CGS#: 100-3M All Rights Reserved Page 2 Printed 06/23/2005

3 2.4 Strength Requirements Acceptable board must meet prescribed strength requirements Bursting Test Apply Mullen or Cady Test as prescribed in Rule 41 of Uniform Freight Classification. (Conditioning for testing shall be in an atmosphere of 50% [+2%] R.H. and 73 o F [+3.5 o ] until equilibrium is reached.) 2.5 Fabrication Fabrication shall be of high quality. All parts shall have true clean-out edges with a minimum of paper dust, ragged edges, and other evidence of poor cutting technique. Cut score (slit score) on double wall board shall be through center liner and at least through one third of thickness of inner corrugated medium. 2.6 Adhesion Facings and corrugated member shall be securely adhered at points of contact. 2.7 Scorelines Scores shall be clearly visible and of adequate depth to permit easy forming, yet shall not cause visible surface breaks on the facings. 2.8 Crushing Crushing of the combined board by printing or other operations shall be held at an absolute minimum. Board should always feel firm when squeezed in the flat direction between fingers. 2.9 Corrugations Corrugations shall be: (per commercial standards) Flute Member per Lineal Ft. Height (Approx) Size (Approximate) Not Including Facings A /16 B /32 C /64 E / Coatings Waxes or other coatings when specified shall be applied only to surface or surfaces indicated. Accidental lap-over to back side of sheets or onto areas not specified shall be cause for rejection Square Folding Flap scores at manufacturer s joint shall be no more than 3/32 mis-aligned from each other.

Measurements should be taken at points near corners and edges so as to avoid measurement between bowed or distorted panel surfaces. 3.2 Folder Dimensions One-piece folder dimensions will be specified as length (the longer dimension of the open face), width (the shorter dimension), and depth (the vertical dimension). The length of the tuck will also be specified. Direction of the corrugations of the one-piece folders shall be parallel to width (shorter dimensions) unless otherwise indicated on item specification. 3.3 Sheet Dimensions Unless otherwise specified, the length dimension of pads, creased sheets, and other sheet forms shall be parallel (with) to corrugation. Dimensions shall be overall dimension of sheet. 3.4 Score Distances Distance between score lines when specified will be from center-to-center of scorelines. 3.5 Dimensional Tolerances Inside dimensions of boxes and other container forms shall be within the tolerances shown below of those specified with the container set up in its form ready for use. All Die-Cut Forms Regular Run (Rotary) Forms Up to /16 From 3 to /16 Over /32 Under 3 or over / Identification of symbols used for: 1. Design Specifications 2. Product Specification Drawings 3. Die Drawings The following symbols are to be used on drawings of corrugated parts: Regular Score (crease) Reverse Reverse Score (or opposite side of sheet) Cut Score (slit score) Reverse Reverse Cut Score (or opposite side of sheet) CORR Perforation (indicated size): Example: 1/8 x 1/8 or 1/4 x 1/4 or 1/8 cut x 1/2 Direction of Corrugation Center Line Cut Line (inside or on edge of part) CGS#: 100-3M All Rights Reserved Page 4 Printed 06/23/2005

9 Fabrication - Edges of sheets and slots are not cut cleanly Flaps of boxes are incorrect length. Do not meet by 1/8 or more or overlap by 1/16 or greater, except when item specifications call for special flap length Scorelines -- Part is difficult to form because scorelines are not deep enough Crushed Board - Printing impressions are greater than.040 deep as measured from undisturbed portion of the sheet Flute Substitution - Flute size not as specified Coatings - Surfaces other than those specified show coating material Joint - Manufacturer s joint of a type other than that specified. Length of tape different than internal box depth by more than 1/8. Gap between abutting ends of box blanks not within specified tolerances. Tape not centered within specified tolerances over joint gap Printing - Layout not as specified Coverage of ink allows the board to be visible through the inked area resulting in unsightly appearance. Excessive ink resulting in filled in type or fuzzy appearing edges on printed areas which result in illegible copy. Color does not match Pages 2.1, 2.1.1, 2.1.2, or (as applicable) of Printing Specification Preparation for Shipments Actual count per marked bundle varies by more than 5%. Average count of all bundles shall be greater or equal to quantity marked on bundles. Load loose on pallet allowing loss of material. Excessive tension on strapping or twine causing cut through sidewalls of boxes or deformation which results in unusable material. 8.3 Minor Defects Defects of this nature would normally result in use of the packaging with supplier notification as to the defective items noted Board has washboard appearance Occasional bits of cutting debris on or among parts Registration of copy is more than 1/8 off from prescribed position but less than 1/ Ink is slightly smeared showing fuzzy appearing edges along printed areas Board is crushed in printed areas more than.025 from undisturbed areas, but not more than Bundle count is more than 2% off marked quantity but not more than 5%. Average count of all bundles shall be greater or equal to quantity marked on bundles Excessive tension on bundle ties causes damage to container edges on outside of bundles causing unusable material Excessive slack causes bundles to be unstable and difficult to control. ** End of Document ** CGS#: 100-3M All Rights Reserved Page 9 Printed 06/23/2005
