工程级反光胶带
工程级反光胶带，也是比较常见的5100工程级反光膜，材质是以大玻璃微珠PET为原材料制成的，具有大广角反射（接近180度平角依然反光）、容易刻字、贴板、耐候性、不易干裂、加厚面层和背纸
（防晒、防水、耐冻）的特性，常见用于高速公路临时标牌，一、二级公路等路牌施工，地下停车场标牌、文明用语等，产品如下图：
The second type is engineering grade reflective tape, which is also a
common 5100 engineering grade reflective film. The material is made of
large glass bead pet. It has large wide angle reflection (close to 180
degree flat angle still reflects light), easy to engrave, paste board,
weather resistance, not easy to dry crack, thicken the surface layer and
back paper (sunscreen, waterproof, frost resistant) characteristics,
commonly used in the construction of temporary signs on expressways,
road signs of first and second class highways, signs of underground
parking lots, civilized expressions, etc., as shown in the following

第三类，晶彩格反光胶带，表面蜂窝状的反光胶带的代表性产品，多以PVC材质为原材料，具有耐寒性、阻燃性、 防水性，多适用于喷绘机、户外写真机直接喷绘，应使用溶剂型油墨，不可使用户内写真机和水性油墨喷绘；适合于 PVC 透明油墨丝印这种场景。产品图如下：
The third category is crystal lattice reflective tape. The
representative products of honeycomb surface reflective tape are mostly
made of PVC material, which has cold resistance, flame retardancy and
water resistance. It is suitable for direct painting of inkjet printer
and outdoor photo machine. Solvent based ink should be used instead of
internal photo machine and water-based ink. It is suitable for screen
printing of transparent PVC ink. The product diagram is as follows:
