Preferably, the pattern protrusions or the pattern grooves are formed by a plurality of groups of petals which are regularly arranged, and the directions of two adjacent groups of petals are opposite.

The above arrangement rule means that the petals in the group are oriented in the same direction. Such as to the left or right as viewed in fig. 2. The opposite orientation is one set to the left and the other set to the right.

Preferably, the pattern protrusions or the pattern grooves are formed by a plurality of groups of petals which are irregularly arranged, and the petals in each group face oppositely.

The irregular arrangement means that the petals in the group are not in the same orientation, two or more adjacent petals can face leftwards, the other two or more petals can face rightwards, and the like, or the petals in the group face in different orientations. The petals of an adjacent group are oppositely oriented relative to the group.

Preferably, the pattern protrusions or the pattern grooves are formed by arranging a plurality of petals in the same or different directions.

The arrangement refers to the petal individual arrangement in any direction.

Preferably, the petals extend from the forming edge to the tail end of the pattern bulge or the pattern groove in an inclined mode. The side surfaces of the petals are inclined surfaces, so that a rough surface can be better established, and the national standard requirements are met.

Compared with the prior art, the beneficial effects of the utility model are that:

firstly, the forming template is formed by embossing, so that the effect of rough surface is achieved, and the design requirement is met;

secondly, the forming template is formed in one-step by stamping, secondary processing is not needed to be carried out on the rough surface, the process cost and the personnel cost are saved, the labor intensity is reduced, and the productivity and the efficiency are improved;

compared with the PE film sticking, the scheme has the advantages that the working procedures are reduced, the resources are saved, the generation of garbage is reduced, the efficiency and the productivity are greatly improved through one-step forming, and the cost is saved;
