Low Lignin Document Storage Box
This specification covers the requirements for a document storage box which is one piece, shipped flat, self locking, and made from low lignin corrugated board.
The shipped flat clam shell box shall consist of one B- or E-flute corrugated singlewall (double-faced) board, comprised of two facings (liners) adhered to one fluted medium with fluting running perpendicular with the spine of the box as indicated in [Figure 1-1]. Assembly shall be self locking. Assembly shall not include adhesive or metal fasteners. Construction shall be such that the self locking walls are double thickness and alternate, that is, when the box is closed, both side walls and front wall shall be double thickness. The self locking assembly shall be such that the tabs fit snugly into "U" shaped incisions cut in the top and bottom of the box. See [Figure 1.2], [Figure 1.3], and [Figure 1.4]. All fold lines are to be scored or crimped, with no perforations. When the paperboard is scored twice to assemble a double wall, the space between parallel scores shall not exceed two board thicknesses. A shallow thumb cut shall be centered on the outside foredge. The thumb cut shall not exceed 1/4" in height. See [Figure 1.1] and [Figure 1.2], [Figure 1.3], and Figure 1.4. The distance between the lower edge of the extension flaps at the spine and the tray of the box shall not be greater than 1/8". The spine of the box shall be cut so that it is flush with the side walls when the assembled box is closed. See [Figure 1.1] and [Figure 1.2], [Figure 1.3], and [Figure 1.4] (drawings are not to scale).
The dimensions of the box shall be specified in the contract as inside measurements in the following order: length, width, and depth with a tolerance of plus or minus 1/16"; and the specified maximum outside dimensions. All box sizes shall be constructed from the same corrugated board type.
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-236cm-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 T406cm-88). Surfaces shall be free of knots, shives, and abrasive particles.
The color shall be gray or tan.
Alkaline sizing (surface, internal, or both) shall be used (ASTM D4988-89).
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 10.0 when tested according to TAPPI T509cm-88.
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-236cm-85.
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-91).
(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
-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
The corrugated paperboard thickness shall be no greater than 0.125 inches and no less than 0.115 inches for B-flute and no greater than 0.073 inches and no less than 0.062 inches for E-flute when tested according to TAPPI T-411 om-89.
The corrugated paperboard shall be tested for stiffness in accordance with TAPPI T489cm-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 an average minimum stiffness of 3700 plus or minus 1000 Taber Stiffness Units for B-flute and 2600 plus or minus 1200 Taber Stiffness Units for E-flute. Collapse of the corrugating medium shall constitute failure.
The corrugated paperboard shall be smooth and free of knots, shives, 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.
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-452cm-87.
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 panels 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. Perforations along fold lines are not acceptable. Scores shall be continuous and deep enough to permit precise folding during assembly. When the paperboard is scored twice to assemble a double wall, the space between parallel scores shall not exceed two board thicknesses. All folded edges shall be free of fraying, cracks, and breaks. The lid shall be able to withstand repeated opening without cracking, splitting, fraying, or otherwise losing strength along the hinge.
Shallow thumb cut on outer foredge shall be smooth, centered, and symmetrical.
Paperboard fluting shall be perpendicular to the spine. (See Figure 1.)
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.
Preparation for Delivery
The document storage boxes shall be shipped flat in a standard commercial container that is sealed with tape. The number of knocked down boxes to be packed in each container shall be specified in the purchase order.
