Mismatch Between Paper Selection and the Gift Wrap Square Box.
If the thickness and toughness of the selected wrapping paper do not match the hardness and size of the surface of the gift wrap square box. For example, overly thin wrapping paper is prone to deformation due to pulling and pressing forces during the process of fitting the gift wrap square box, which in turn causes wrinkles.If the fiber direction of the wrapping paper is inconsistent with the pasting direction of the gift wrap square box, the paper will also be unable to bear force evenly during fitting, resulting in wrinkles.
Problems with Pasting Operation.
When pasting the surface of the gift wrap square box, if the position and amount of glue or tape applied are not appropriate. For example, if the glue is applied unevenly and there is too much glue in some areas, the wrapping paper will swell after being soaked by the glue, and cannot fit perfectly with the surface of the gift wrap square box. The excess glue will also cause uneven force on the local area of the paper, forming wrinkles.If you do not smooth the paper slowly from the center to the surroundings of the gift wrap square box when pasting, but press it randomly, air will easily remain between the wrapping paper and the box surface, and the air will lift the paper, forming irregular wrinkles.
Influence of Environment and Storage.
If the gift wrap square box is stored in a humid environment, the wrapping paper will absorb moisture and swell slightly. When the environment becomes dry later, the paper will shrink, causing it to separate from the surface of the gift wrap square box and form wrinkles.In addition, if the gift wrap square box is squeezed or collided after pasting, the originally flat wrapping paper on the box surface will also shift and wrinkle.
