What is external light box cloth internal light box cloth?

Light box cloth is divided into inner light box cloth and outer light box cloth, respectively called inner light cloth and outer light cloth.

The surface of the inner light cloth is blue, which is a kind of inkjet cloth specially used for the production of light boxes. Its light transmission is higher than that of ordinary inkjet cloth, but it can not be spliced because the spliced gap will be seen clearly after the lighting.

The surface of the outer light cloth is yellow, and it has excellent resistance to light. The outer lighting cloth can dry quickly, both sides can print, print different images, and the outer lighting cloth has good air permeability, high strength and light weight, excellent inkjet performance, stable ink absorption, rapid drying, and strong color expression.

Light box cloth: mainly used in advertising light boxes, banners, large posters, construction sites outside the wall scenery, large T-shaped billboards. Light box cloth printing using oily ink, rain and sun is not easy to fade, durable, which is the biggest feature that distinguishes it from indoor photo advertising materials. The light box cloth material has strong tensile resistance, stable chemical composition and is not easy to deform, and can be used for outdoor advertising for a long time.

How is PETG board different from acrylic board?

1. Different properties: PETG is an amorphous copolyester. In its production process, because a certain amount of ethylene glycol is replaced by 1, 4-cyclohexane dimethanol(CHDM), crystallization can be prevented, thereby improving the processing and manufacturing and transparency. Acrylic is a replacement product of plexiglass.

2, the characteristics are different: the light box made of acrylic plate has good light transmission performance, pure color, rich color, beautiful and flat, taking into account the two effects of day and night, long service life, does not affect the use of characteristics. PETG sheet products are highly transparent, excellent impact resistance, especially suitable for forming thick wall transparent products, its processing and molding performance is excellent.

3, different uses: acrylic plate is widely used in instrument parts, car lights, optical lenses, transparent pipes and so on. PETG sheets are easy to produce products with complex shapes and large tensile ratios.

Extended information:

Note:

1, acrylic plate can not be stored with other organic solvents, but can not contact organic solvents.

2. During transportation, the surface protective film or protective paper can not be scratched.

3, can not be used in the temperature of more than 85℃ environment.

4, clean acrylic sheet only with 1% soapy water, soapy water with soft cotton cloth, do not use hard objects or dry wipe, otherwise the surface is easy to be scratched.

5. The cold and thermal expansion coefficient of the acrylic plate is very large, and the expansion gap should be considered due to temperature changes.
