Definitions

  • a moisture barrier coating e.g., a polymeric material
  • the process for manufacturing such packages is usually intensive and costly. Further, the presence of the moisture barrier coating can interfere with gluing during assembly of the carton because some adhesives may not adhere properly to the polymeric material of the moisture barrier coating.
  • This application is directed generally to a material or structure that is suitable for use as cartonboard, and a carton blank and/or carton formed from the cartonboard.
  • the material generally includes a printed (or printable) facing layer joined to a single-face corrugated substrate.
  • the material also includes a barrier layer for reducing the transmission of moisture through the material.
  • the barrier layer may be disposed on a side of the printable facing layer facing the flutes (or “medium”) within the interior of the cartonboard structure. In this manner, the material may be formed into a carton using conventional gluing techniques without the barrier layer preventing gluing of the carton.
  • the barrier layer may comprise any suitable material, for example, a polymer film or polymeric material or coating.
  • the cartonboard may have a moisture vapor transmission rate of about 1 g/100 sq. in/day. In another aspect, the cartonboard may have a moisture vapor transmission rate of less than about 1 g/100 sq. in/day.
  • a carton formed according to the disclosure may generally have excellent top load compression and increased bulge resistance while maintaining a barrier to moisture transmission, thereby providing improved overall product protection while reducing carton failure and, therefore, unsellable products (“unsalables”). Accordingly, the material may be especially suitable for large load cartons (e.g., greater than 4 L), although it may be used for other carton sizes.
  • FIG. 1 is a schematic cross-sectional view of an exemplary cartonboard according to one aspect of the disclosure
  • FIG. 2A is a perspective view of an exemplary carton that may be formed from the cartonboard of FIG. 1 according to another aspect of the disclosure, in a closed configuration with the tear strip intact;
  • FIG. 2B is a perspective view of a top portion of the carton of FIG. 2A , with the tear strip removed;
  • FIG. 2C is a perspective view of a top portion of the carton of FIG. 2B , in an open configuration
  • FIG. 2D is a schematic top plan view of one side of an exemplary blank for forming the carton of FIG. 2A according to yet another aspect of the disclosure.
  • FIG. 1 is a schematic cross-sectional view of an exemplary corrugated cartonboard structure 100 according to one embodiment of the disclosure.
  • the structure 100 generally comprises a corrugated substrate 102 including a back liner (or facing layer) 104 joined to a corrugated medium (or flutes) 106 .
  • the structure 100 also includes a top liner (or facing layer) 108 and a substantially continuous barrier layer 110 (e.g., moisture barrier layer) disposed on a side of the top liner 108 facing the medium 106 .
  • the barrier layer 110 on the top liner 108 may be joined to the medium 106 and to the top liner 108 using adhesives 112 , 114 , or using any other suitable material.
  • adhesive 114 may be omitted in some embodiments, as discussed below. Further, it will be appreciated that other embodiments may include a fewer number of layers or a greater number of layers.
  • the facing layer 108 may comprise coated recycled board (CRB), SBS, white top kraft, or any other suitable material.
  • the facing layer 108 may have any suitable basis weight, for example, from about 40 to about 100 lb/msf (lb/1000 square feet), for example, from about 50 to about 80 lb/msf, for example, about 69 lb/msf.
  • the facing layer 108 may have a quality suitable for printing, for example, using lithographic reproduction or other printing techniques.
  • the facing layer 108 may have a basis weight of from about 40 to about 70 lb/msf, for example, about 56 lb/msf. However, other basis weights and ranges of basis weights may be used, depending on the strength requirements for the carton.
  • the barrier layer 110 may comprise any suitable material that provides the desired degree of resistance to moisture for the particular application (e.g., to prevent hardening or clumping of the powder or granular package contents), for example, a polymer or polymeric material in the form of a polymer film or a polymer coating.
  • the barrier layer 110 may comprise a polyolefin, for example, low density polyethylene or high density polyethylene.
  • the barrier layer 110 may comprise a polyester, for example, polyethylene terephthalate.
  • countless other polymers or polymeric materials may be suitable.
  • the barrier layer 110 may have any suitable thickness, for example, from about 0.5 mil to about 5 mil, for example, from about 1 to about 4 mil, for example, from about 2 to about 3 mil, depending on the level of moisture barrier that needs to be achieved. However, other thicknesses and ranges of thicknesses are contemplated.
  • the cartonboard may have a moisture vapor transmission rate of from about 0.25 to about 1.5 g/100 sq. in/day (as measured using ASTM D895-79), for example, from about 0.5 to about 1 g/100 sq. in/day. In another aspect, the cartonboard may have a moisture vapor transmission rate of less than about 1 g/100 sq. in/day (as measured using ASTM D895-79), for example, less than about 0.9, less than about 0.8, less than about 0.7, less than about 0.6, or less than about 0.5 g/100 sq. in/day. However, the cartonboard may have a different moisture vapor transmission rate, depending on the needs of the particular packaging application.
  • the barrier layer 110 may undergo one or more surface treatments to improve adhesion between the barrier layer 110 and the medium (e.g., flutes) 106 of the corrugated substrate 102 .
  • the barrier layer 110 may be corona treated, for example, to a dyne level of from about 30 to about 50 dyne, for example, about 40 dyne.
  • other suitable treatment levels may be used.
  • other surface treatments for example, plasma treatment, may be suitable.
  • the barrier layer 110 may be joined to the medium (e.g., flutes) 106 and to the facing layer 108 in any suitable manner.
  • the barrier layer 110 may be joined to the medium 106 using an adhesive 112 , for example, a polyvinyl alcohol (PVA) adhesive (e.g., National Henkel 33-9192, Henkel North America, Düsseldorf, Germany).
  • PVA polyvinyl alcohol
  • the medium 106 may be joined to the liner 104 in any manner, for example, using an adhesive 114 .
  • One exemplary suitable adhesive 114 may comprise starch; however, any other suitable adhesive material may be used.
  • the particular adhesive(s) 112 , 114 chosen may depend on the composition of the barrier layer 110 and/or other numerous factors. Further, it will be appreciated that adhesive 114 may be omitted in some embodiments, for example, where layer 112 is applied to layer 108 as a coating (extrusion or otherwise).
  • any suitable corrugated substrate 102 may be used to form the cartonboard 100 of FIG. 1A .
  • the facing layer or back liner 104 of the corrugated substrate 102 may comprise paper or paperboard have a basis weight of from about 40 to about 70 lb/msf, for example, about 56 lb/msf.
  • the medium (e.g., flutes) 106 may comprise paper or paperboard having a basis weight of from about 20 to about 40 lb/msf, for example, about 33 lb/msf.
  • any suitable flute size may be used for a given application. In one example, flute size B may be used.
  • the flute size may be adjusted to provide the desired degree of strength in the resulting carton, with A, B, and C flutes generally providing more strength than E, F, N, or G flutes.
  • All or a portion of the medium 106 and/or facing layers 104 , 108 may comprise recycled fiber, and in one example, the medium comprises at least 50% recycled fiber. However, other possibilities are contemplated.
  • the present cartonboard provides numerous advantages over known commercially available packages. For example, as will be appreciated by those of skill in the art, by positioning the barrier layer 110 as an interior layer of the structure 100 (rather than an outermost layer or surface), the barrier layer polymer does not interfere with the adhesives used in erecting and gluing the carton. Further, since many carton forming machines include heated components (e.g., rollers), positioning the barrier layer as an interior layer generally prevents any undesirable softening or melting of the barrier layer polymer on the equipment, for example, when the machine is stopped and the carton or carton blank is exposed to heat for an extended period of time. Additionally, the present cartonboard may offer a simplified carton construction as compared with traditional bag-in-box type packages or other barrier packages.
  • FIG. 2A schematically illustrates an exemplary carton or package 200 for containing a powdered or granular product or other article, in a closed configuration.
  • the carton 200 includes a front panel or wall 202 , a back panel or wall 204 ( FIG. 2C ), a pair of opposed end or side panels or walls 206 , 208 ( FIG. 2C ), and a pair of opposed end closure assemblies 210 , 212 (discussed in detail below).

  • a “fold line” can be any substantially linear, although not necessarily straight, form of weakening that facilitates folding therealong. More specifically, but not for the purpose of narrowing the scope of the present invention, a fold line may be a score line, such as lines formed with a blunt scoring knife, or the like, which creates a crushed portion in the material along the desired line of weakness, a cut that extends partially into a material along the desired line of weakness, and/or a series of cuts that extend partially into and/or completely through the material along the desired line of weakness; or any combination of these features.
  • one type of conventional tear line is in the form of a series of cuts that extend completely through the material, with adjacent cuts being spaced apart slightly so that a nick (e.g., a small somewhat bridging-like piece of the material) is defined between the adjacent cuts for typically temporarily connecting the material across the tear line.
  • the nicks are broken during tearing along the tear line.
  • Such a tear line that includes nicks can also be referred to as a cut line, since the nicks typically are a relatively small percentage of the subject line, and alternatively the nicks can be omitted from such a cut line.
  • various exemplary blanks and packages are shown and described herein as having fold lines, tear lines, score lines, cut lines, kiss cut lines, and other lines as extending from a particular feature to another particular feature, for example from one particular panel to another, from one particular edge to another, or any combination thereof.
  • such lines need not necessarily extend between such features in a precise manner. Instead, such lines may generally extend between the various features as needed to achieve the objective of such line. For instance, where a particular tear line is shown as extending from a first edge of a blank (or panel) to another edge of the blank (or panel), the tear line need not extend completely to one or both of such edges. Rather, the tear line need only extend to a location sufficiently proximate to the edge so that the removable strip, panel, or portion can be manually separated from the blank or package without causing undesirable damage thereto.
