What are the shortcomings of the existing PET micro-prismatic reflective tape?

As a more common reflective film product, PET micro-prismatic reflective tape is widely used in daily production and life. With the continuous improvement of market demand, people also put forward higher requirements for its products. At present, in the existing PET micro-prismatic reflective tape production and processing process is limited by the production process and equipment manufacturing capacity. It usually relies on intermittent production technology to produce the PET micro-prismatic reflective tape into a product form with limited specifications. PET micro-prismatic reflective tapes need to be spliced into a reflective film product of the required length through splicing technology. However, in the actual production and processing process, the production efficiency of this kind of monolithic production and splicing processing is low, and it will cause serious waste of raw materials, and excessive processing procedures will affect the uniformity of the reflective brightness of the PET micro-prismatic reflective tape. At the same time, the obvious splicing seams on the surface of the PET micro-prismatic reflective tape also bring a lot of inconvenience to its normal use. The prism structure of the existing PET micro-prismatic reflective tape is unreasonably set, and the effective incident angle and the observation angle are small, which cannot meet the comprehensive reflective recognition requirements under different lighting conditions and different recognition distances in practical applications. In addition, the large-size prism structure is difficult to lift out during production and requires high coating performance, which causes the problem of excessive production costs.

How to solve the existing shortcomings of PET micro-prismatic reflective tape?

A PET micro-prismatic reflective tape includes a transparent base film and a micro prism layer. When the company produces PET micro-prismatic reflective tape, a layer of light-curing paint is coated on the surface of one side of the transparent base film; the photocurable coating is formed by a master mold with a micro prism structure, and the micro prism structure of the master mold is complementary to the micro prism layer of the PET micro-prismatic reflective tape. The photo-curing coating is cured by light irradiation during the molding process; the master mold is removed so that the photo-curing coating on the surface of the transparent base film forms a micro-prism layer. It also includes: performing surface treatment on the surface of the formed micro prism layer; after the surface treatment, depositing a reflective layer on the surface of the micro prism layer.

The micro prism layer of our PET micro-prismatic reflective tape includes a variety of different specifications of triangular pyramid structure prisms and truncated triangular pyramid structure prisms, which can increase the observation angle of the micro prism reflective film and reduce the PET micro-prismatic reflective tape’s difficulty of demolding in the manufacturing process.
