The SMP material is made of the shape memory polymers, SMPs are polymeric smart materials that have the ability to return from a deformed state (temporary shape-stable at -10℃ to 50 ℃) to their original (permanent) shape induced by an external stimulus (trigger), such as temperature change. It can store embossed logo/text shape information in the synthetic-paper-like film, and release these 3D patterns when exposed ≥65°C in 3 seconds. The material is harmless and has passed the EU ROHS Test and the ISO 9001:2008.
