Monoaxial MDO stretching machine for films (machine direction orientation) MDO

Overview MDO (Machine Direction Orientation) is a proven monoaxial stretching process for cast and blown films that optimizes film properties for specific applications. With W&H MDO systems, films can be processed on- or offline to improve barrier performance, tensile strength, stiffness, shrink behaviour, gloss and transparency, while enabling material savings for cost-efficient barrier solutions.

Your advantages

• Improved film barrier and mechanical properties
• Enhanced tensile strength and stiffness
• Optimized shrink and dimensional stability
• Increased gloss and transparency
• Reduced use of expensive raw materials
• Adaptable to a wide range of film formulations and applications

Film applications: Examples

• Barrier films
• Breathable films for hygiene and construction sectors
• Heavy-duty sacks
• Adhesive tapes
• Labels
• Stand-up pouches
• Food packaging

NEW: Mini Nip Roller Technology Improve MDO production quality and process robustness with Mini Nip Roller Technology.

• Wider and more stable process window for diverse MDO applications
• Superior film profile after stretching
