Packaging material having patterns of microsphere adhesive members that allow for bending around objects

A packaging material, comprising:

• a bendable substrate having a surface;
• and
• a plurality of adhesive members adhered to the surface, each adhesive member having a triangular shape and comprising a plurality of expandable microspheres,
• wherein the adhesive members are arranged on the surface in a pattern so as to define (i) a first pair of linear arrays of the adhesive members that extend along a first direction and are spaced from one another so as to define a first gap that is elongate along the first direction between the linear arrays of the first pair, each linear array of the first pair having a plurality of linear edges that are aligned with one another along the first direction so as to define the first gap, (ii) a second pair of linear arrays of the adhesive members that extend along a second direction, angularly offset from the first direction, and are spaced from one another so as to define a second gap that is elongate along the second direction between the linear arrays of the second pair, each linear array of the second pair having a plurality of linear edges that are aligned with one another along the second direction so as to define the second gap, and (iii) a third pair of linear arrays of the adhesive members that extend along a third direction, angularly offset from the first and second directions, and are spaced from one another so as to define a third gap that is elongate along the third direction between the linear arrays of the third pair, each linear array of the third pair having a plurality of linear edges that are aligned with one another along the third direction so as to define the third gap, and
• wherein the packaging material is configured such that the substrate bends between the adhesive members along the first gap, the second gap, and the third gap.

• wherein each linear array of the first and second pairs of linear arrays has a plurality of array elements, and each array element defines a rectangle formed from first to fourth ones of the adhesive members, each adhesive member having a triangular shape, the first and third adhesive members spaced from the second and fourth adhesive members so as to at least partially define a gap that extends along a first oblique direction, and the first and second adhesive members spaced from the third and fourth adhesive members so as to at least partially define a gap that extends along a second oblique direction, wherein the first and second oblique directions are each at an oblique angle relative to the first and second directions and are at a non-zero angle relative to one another.
