Our candlebags are made of Kraft paper white, 60 gm² / PE 23 gm² and, like paper, are flammable. We do not offer "light flammable" light bags, mostly imported from China. If you attach importance to high safety standards, we recommend that you have the test report according to DIN 4102 (B1 - flame retardant) submitted. Also, a data security sheet of the adhesive and binder or the impregnating agents used would be recommended.
