The hole row on the inter-surface layer transfer portion 34 side is parallel to the end surface of the inter-surface layer transfer portion 34, and the distance between them is 1.5mm to 10mm. The distance between the center point of the longitudinal direction of the groove 51 and the end face of the inter-skin layer joint 34 is defined as the distance between the center point of the longitudinal direction of the ridge 52 and the end face of the inter-skin layer joint 34. In actual use, different interval sizes can be selected according to different daily necessities, for example, if the daily necessities are handbag products, the interval size can be set to be 2-7 mm; if the tray is a containing tray product, the interval size can be set to be 2-4 mm; in case of a box-like product, the interval size can be set to be between 2 and 6 mm; in the case of a barrel product, the gap size may be set to between 3-5 mm.

As mentioned above, the panel body 31, the outer skin portion 32, the inner skin portion 33, and the inter-skin interface 34 are integrally formed by injection molding using a mold, the cortical texture region is formed by performing laser treatment and sand blasting treatment on the corresponding region of the mold surface, and the texture concave-convex region 40 further includes a plurality of pits 43 formed corresponding to the sand blasting treatment, as shown in fig. 12, the plurality of pits 43 are randomly distributed in the plurality of texture concave stripes 41 and the plurality of texture convex portions 42.
