| 摘要 |
The invention relates to a plastic bag (10), made from plastic film (20) with one or more ports (30). At least one of said ports (30) comprises a plastic element (40), welded between two layers of plastic film (22, 24), thus forming a port welded region (50). The plastic element (40) in the port welded region (50) may be compressed. The cross-section of the free, uncompressed plastic element (40) runs in the form of a wedge to the lateral edges of the port welded region (50). The plastic element (40) comprises at least one first edge (80) in the port welded region (50). The plastic bag (10) permits an optimised production method and is particularly suitable for application in the medical field. |
