Abstract: A product required to be kept in a clean environment is packaged by removing outer layers of a multi-layer film and immediately thereafter introducing its inner core sheet inside a clean room. A bag with an opening is produced inside the clean room by superposing and sealing together two of such core sheets, by splitting one core sheet into two sub-layers and superposing and sealing together these two sub-layers or by folding one core sheet and superposing and sealing together its folded parts. The product may be packaged in such a bag either by using the same apparatus which makes the bag or by using another apparatus. The bag is made of a multi-layered material, and its outer layer is peeled off immediately before it is put inside a clean room to be torn apart and to have the produce taken out.
