Advantages Of Mono-material PBL One-time Blown Tube
Laminate(One-formed Tube Thick Film) Recyclable Mono-Material PBL Tube Laminates- 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: - 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.
- 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.
- 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.
