Low Lignin Flat Storage Box

May 1996

Scope

This specification covers the requirements for an assembled flat storage box with a removable full telescoping lid, made from low lignin corrugated board.

Requirements

Construction

The two piece box shall consist of a top and bottom assembled from B-flute corrugated single-wall (double-faced) board, comprised of two facings (liners) adhered to one fluted medium. The assembled box shall consist of two die cut corrugated box blanks cut, scored, and adhered as indicated in Figure 1. Adhesives shall meet the NARA Quality Assurance Provisions included in this specification. Assembly shall not include metal fasteners. Construction shall be such that the adhered walls are double thickness and alternate. The full telescoping lid shall be 1/4" shallower than the box bottom height to allow ease of removal. When the paperboard is scored twice to assemble a double wall, the space between parallel scores shall not exceed two board thicknesses. Drawing is not to scale.

Dimensions

The dimensions of the box shall be specified in the contract as

inside box bottom

measurements in the following order: length, width, and depth with a tolerance of plus or minus 1/16".

Paperboard

Composition
All layers of the corrugated paperboard laminate shall be made from cotton or linen pulp, fully bleached chemical wood pulp, or a mixture. The paperboard shall be free of groundwood (ASTM D1030, X 5 Spot Stains and Tappi T-236om-85), alum-rosin sizing (ASTM D549-88), particles of metal, waxes, plasticizers (i.e. wet strength additives), plastics, and shall contain less than 0.0008 percent reducible sulfur (Tappi T406om-88). Surfaces shall be free of knots, strives, and abrasive particles.


Color
The color shall be gray.


Sizing
Alkaline sizing (surface, internal, or both) shall be used (ASTM D4988-89).

Alkaline Reserve
The corrugated paperboard shall have a minimum of 3 percent calcium carbonate, magnesium carbonate, or a combination of both evenly distributed throughout all layers of the lamination, when tested according to ASTM D4988-89.

Hydrogen Ion Concentration (pH) (cold extraction method)
The pH value of the corrugated paperboard shall be between 8.0 and 9.6 when tested according to TAPPI T509om-88.

Lignin
To demonstrate the adequacy of bleaching or lignin removal, all layers of the corrugated paperboard shall have a negative reading in the phloroglucinol test when tested according to ASTM D1030 or shall have a KAPPA number of 5 or less when tested according to TAPPI T-236om-85.

Abrasion
Outer surface of the paperboard shall show a loss of less than 0.3 percent of the total weight (mounting card and sample) when tested with #CS 10 wheel and 100 wear cycles (TAPPI T-476om-01).

Surface Smoothness (to determine the property of adhesion of a pressure sensitive label to the paperboard surface)
The surface of the paperboard shall hold a piece of weighted pressure sensitive tape securely in place for at least 10 minutes in 6 out of 9 trials, when tested according to ASTM D286-90, Procedure B modified as follows: -use 3M brand #810 3/4" wide, pressure sensitive tape to conduct the test -adhere the tape to the paperboard surface with 2 rolls of a 10kg steel roller; allow samples to set 3 days before testing -suspend a 2OZ weight from the tape

Thickness
The corrugated paperboard thickness shall be no greater than 0.125 inches and no less than 0.115 inches for B-flute when tested according to TAPPI T-411 om-89.

Stiffness
The corrugated paperboard shall be tested for stiffness in accordance with TAPPI T-489om-92 except that for each specimen tested the corrugations shall run in the long direction of the specimen. Test conditions shall include 7.5 degrees deflection and a 5,000 Taber unit weight. The board shall have a stiffness of between 3,000 and 6,000 Taber Stiffness Units. Collapse of the corrugating medium shall constitute failure.

Finish
The corrugated paperboard shall be smooth and free of knots, strives, and other abrasive particles. The paperboard shall be free of dirt, marks, stains, surface or edge damage, or other imperfections or contaminations which might affect the utility or appearance of the product.

Color Retention
Dyes used to color the paperboard shall show no bleeding when soaked in distilled water for 48 hours while held in direct contact with white bond paper. The board shall not show a loss or gain of more than 5 points of brightness after exposure in a Sunlighter II apparatus for 96 hours or a fadeometer for 36 hours, when tested according to TAPPI T-452om-87.

Adhesive Used in Laminating the Corrugated Board

Water resistant purified starch adhesive shall be used which shall contain no free sulfur or other impurity which would detract from the properties of the paperboard (i.e. reduce the alkaline reserve, increase the percentage of sulfur, decrease the pH, decrease the stiffness).

Adhesive used in Assembly

Water resistant adhesive shall be used to adhere fold downs in both box top and bottom. Pressure sensitive adhesives shall not be used in assembly. When aged in an over at 50 degrees centigrade and 87 percent relative humidity, the adhesive shall not soften or run, but shall firmly and evenly adhere fold downs to box sides. The properties of the adhesive shall not detract from the properties of the corrugated board (i.e. reduce the alkaline reserve, increase the percentage of sulfur, decrease the pH, or decrease the folding endurance. The adhesive shall not be visible through or alter the color of the corrugated board. If it is necessary to buffer the adhesive, the same buffer as in the corrugated board (i.e. calcium carbonate, magnesium carbonate, or a combination of both) shall be used.

Workmanship

Each box shall meet the requirements stated in this specification, shall be assembled in accordance with good commercial practice, and shall be free of imperfections that may affect its utility or aesthetic appearance.

Each box shall be made to the dimensions specified. When assembled, all components shall fit closely without gaps or warping. All edges shall be cut straight and shall be smooth and even. The corners of the box shall be square. When assembled the top and bottom shall rest flat on a flat plane. When locked into place, the self locking sides shall remain in position. When closed the top and bottom shall fit snugly and remain closed. The completed box shall contain no surface dirt (smudges, fingerprints, and the like) and shall not be marred (dents, bumps, etc.) in any way.

The paperboard shall be scored evenly. When the paperboard is scored twice to assemble adouble wall, the space between parallel scores shall not exceed two board thicknesses. All edges shall be free of fraying, cracks, and breaks.

Identification Markings

The following information shall be legibly embossed on the outside bottom of each box:name of manufacturer, pH range, year of manufacture, and the words low lignin. Figure 2.

Preparation for Delivery

Packaging

The map storage boxes shall be shipped assembled and the box spacers and liners shall be shipped flat in standard commercial containers that are sealed with tape. The number of boxes to be packed in each container shall be specified in the purchase order.

Marking

The outside of each packing container shall be legibly marked with the following information: the purchase order number and the size and number of map storage boxes and associated components packed in the container.
