ABSTRACT:
A pouch or sachet for packaging biologic liquid substances is made of two thermoplastics material films welded together. The weld delimits a pocket. A filler passage is connected to the top of the pocket. One of the thermoplastics material films has a peelable area at the top. The peelable area contains wax. After filling, the pouch is sealed in a sealing area inside the peelable area, near the top of the passage and transversely to its axis. The pouch can be opened easily, in the required area, without using any cutting tools, by manually separating the two thermoplastics material films. Positive guidance is then assured on insertion of a probe into the passage of the pouch.
