Built For You

We can forge tank liners of all sizes and shapes from a range of chemical- and corrosion-resistant plastics. While our team can source any plastic product for our customers, the types they use most often for process tank fabrication include:

  • Polypropylene, or Polypro
  • Polyvinyl chloride, also called PVC
  • Polyvinylidene fluoride, or PVDF
  • High-density polyethylene, also known as HDPE


No two applications are the same, and each has its unique requirements. We understand this, and we can fabricate them for a range of processes. Our tank liners are ideal for the following operations:

  • Photo-etching
  • Food manufacturing
  • Micro-machining
  • Cleaning
  • Pharmaceutical
  • Electro-polishing
  • Electro-plating
  • Passivation
  • Anodizing
  • Galvanizing
  • Semiconductor
  • Rinsing
  • Dipping
  • Non-destructive inspection
  • Bulk chemical transfer

Attention To Detail

At Chicago Plastic Systems, we stand behind our work. All corners of tank liners we fabricate are butt welded before being extrusion welded, ensuring a comprehensive seam through the plastic. This process also provides improved support and strength. Other techniques we use to create long-lasting process tanks include:

  • Corner plates provide reinforcement when the design requires
  • Steel or plastic support can be added to tank sidewalls, eliminating flexing and stress

Every one of our welders is either certified by the American Welding Society and German Welding Society, or they are working towards that distinction while assisting already certified welders.

The German Welding Society, or DVS, is dedicated to education, training, qualification, and certification in the field of welding and related technologies, and the organization is the leader in thermoplastic fabrication techniques. Chicago Plastic Systems is proud to be the only thermoplastic fabrication facility in the United States with 100 percent of its welders either certified by or are currently undertaking apprenticeships with the DVS.

Rehabilitate your existing chemical process tanks with high-quality tank liners from Chicago Plastic Systems. We have the experience and capabilities to create well-performing, simple to install turnkey solutions.
