The production of soft film light box is mainly to assemble the aluminum profile of Kabu light box, and then cut the back plate according to the size. The back plate is mostly made of KT board, and finally the LED light bar and power supply are fixed. The price of soft film light boxes marked by Tianlang is generally around 250 yuan.

To make a soft film painting, we must first sew rubber strips around the soft film. The specification of the rubber strip is12mm wide and 3mm thick. It is necessary to ensure that the size of the soft film is the same as that of the soft film light box after the adhesive tape is sewn, because the four sides of the soft film picture should be stuffed into the card slot, and the size of the actual picture is 2cm smaller than that of the Kabu light box.

At room temperature, the soft film of 1 m can be pulled out 1 cm. If it is winter, the soft film should be made bigger.
