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
