Hi , This is Petko Gluharski from Toni Fil Ltd. Our company has been in Bulgaria for years. Can you provide me with more information regarding the fabric for vacuum cleaner bags - The material of the bag should be 3 layers around 75 - 90 g/m2 all together. At the moment we are using 25 g/m2 Spondbond + 40 g/m2 Meldbond +25 g/m2 Spondbond, but even 25 g/m2 Spondbond + 25-30 g/m2 Meldbond +25 g/m2 Spondbond, is OK for us. Enclosed I’m sending you pictures of the end product and the material with separated layers. Please send me the information to I would appreciate it if you can reply to me as soon as possible. Best Regards
