Flame-retardant cardboard sample 100mL (M1 certificate not provided) – Eurocarton

Cardboard is an extremely flammable cellulosic material, often prohibited in public building decorations without treatment. Fireproofing aims to stop its immediate combustion to meet the M1 standard. However, cardboard is susceptible to moisture. Applying a liquid fire retardant can cause warping or bleed-through of printing inks. This 100ml sample is essential for conducting a “crash test”: it allows you to determine the least invasive application method to preserve the structure of your decorations before purchasing your Cardboard Fire Retardant.

No, this sample has no administrative value and does not provide an M1 certificate. It is used solely to validate technical feasibility. Once your test is successful (no major deformation), you will need to order the Eurocarton sprayer or the 5L container to receive the official documents.

Spray the product onto an inconspicuous area or a scrap piece. Observe whether the cardboard warps as it dries and whether the printed colors remain stable. This will allow you to adjust the spray pattern for the final treatment.
