Bacomex™: Tube heading for plastic tubes
Tube heading for plastic tubes
PTH plastic tube barrier heading using Bacomex™ compression moulding technology
In the production of seamless extruded plastic tubes, the moulded shoulder is known for being the weakest part where oxygen can enter and aromas escape. Bacomex™ multilayer compression moulding technology is an efficient barrier protection embedded into the entire tube head.
Unique Sales Proposition:
  • Technology based on evolutionary PTH equipment
  • One step moulding and assembly process
  • Cost competitive
  • Unchanged shoulder design and no process waste
  • Opens new opportunities for plastic tubes
  • Potential for higher margin tubes
  • Offers extended shelf life packaging for sensitive products
