Analysis of Stretching Machines

As the main equipment for film manufacturing, stretching machines transform ordinary plastics into high-strength and high-barrier functional materials through precise molecular orientation technology!

1. Why is the stretching process irreplaceable?  

Performance Multiplication: Longitudinal and transverse biaxial stretching increases film strength by over 200%.  

Thickness Reduction: Achieves micron-level ultra-thinning, directly reducing material costs.  

Functional Evolution: Endows special properties such as water resistance, oxygen barrier, and temperature resistance.  

Industry Consensus: Key processes for "necklace" materials like lithium battery separators and capacitor films rely on stretching machines!

3. Solving Industry Problems – Ube's Solutions  

Ube Precision Industry has provided advanced technical solutions for common issues in medical packaging production, achieving remarkable results:  

For uneven thickness, an online thickness measurement closed-loop feedback system monitors and adjusts in real time, controlling tolerances to one-third of industry standards.  

To address edge film breakage, an intelligent edge compensation system dynamically optimizes, significantly reducing reject rates.  

For high energy consumption, a waste heat recycling device enables efficient energy use, effectively lowering comprehensive energy consumption and improving production efficiency and product quality.  

4. Application Scenarios  

Ube's technology has achieved performance breakthroughs through targeted equipment and solutions in multiple fields:  

In new energy, for lithium battery separators; in electronics; in packaging, BOPP high-barrier film production lines reduce oxygen permeability and extend shelf life.  

In industrial production, PET optical base film stretching technology achieves haze below 0.5%, successfully replacing imported products and empowering high-quality development across industries.
