SOFIX® is an innovative product that incorporates plastic injected snaps onto the tape. The snap parts are injection molded onto the tape ensuring a secure fit. Attaching machines or attaching dies are not required. The tape is knitted for a soft touch and feel. The tape is also made using recycled PET which is the same material as our NATULON® zippers. Using SOFIX® NATULON® can help reduce the environmental impact of plastic bottles. For example, 10,000 SOFIX® NATULON® of 20 cm length end up recycling 2,910 plastic bottles (29 g/bottle). The yarn used in the tape of SOFIX® NATULON® mechanically recycled fasteners is made from 97% post-consumer recycled material.
