LEAK-PROOF ULTRASONIC POINT-BONDS |
| 摘要 |
A strong, leak-proof seal includes a number of intermittent ultrasonic bonds spaced closely together. At least two layers of material, such as nonwoven webs laminated to a liquid-impermeable film, can be held together by these bond points. The bond points can be arranged in a pattern, such that material that is displaced during the bonding process blocks the passage of any fluid between the bond points. |
