Description

Advantages Of  Mono-material PBL One-time Blown Tube Laminate(One-formed Tube Thick Film)

  • One-time Blown Tube Laminate has good penetration resistance and corrosion resistance，better performance in tube printing and tube making
  • Single material ＞95% can be recycled and reused
  • Compared with the same extruded composite PBL tube laminate, the one-time blown tube has a significant improvement in water resistance and oxygen resistance
  • One-time blown tube laminate can replace ABL tube laminate of the same thickness

Conclusions：

  1. The MD and TD yield strength of the once-formed tube is 25-30% greater than the extruded laminate PBL tube (A,B), making it more rigid.
  2. 60% HD one-formed tube and aluminum-plastic ABL tube(C) have the same yield strength, so the mechanical properties and hardness are equivalent under the same thickness.
  3. Compared with the extruded laminate PBL tube(A,B) of the same thickness, the one-formed tube has greatly improved water-blocking and oxygen-blocking performance.
