| Résumé : |
The use of bio-based plastic materials – accompanied by high prices, new packaging designs and frequent technical refinements – present packaging manufacturers with a whole range of challenges. As more biopolymer packaging makes its way to the market, ultrasonic welding is proving its worth in sealing these import new polymers. Today, modern vertical form, fill and seal machines (VFFS) are capable of sealing through the package contents. |
| Note de contenu : |
- The sensitive material requires new sealing equipment
- The advantages ultrasonic welding systems offer
- Quality control immediately sorts out faulty batches
- Fig. 1 : Reducing waste due to weld failures, Branson ultrasonic components for VFFS systems by Emerson can seal directly through package contents and other contaminants at the sealing point of a wide variety of product packages
- Fig. 2 : The Bosch VIS aroma protection valve is connected to the packaging film by ultrasonic welding. The valve enables degassing and at the same time prevents the inflow of harmful oxygen
- Fig. 3 : Ultrasonically welded seals ensure the integrity of Pocket Shot, a 50 ml, three-layer plastic film pouch containing various spirits. Pocket Shot is a durable alternative to plastic bottles for people on the go |
