Highest Standards
It’s important to note that we weld our plastic tanks to the strict German DVS welding standards. This specification is used to measure the integrity of commercial chemical and acid tanks, assuring the long-lasting integrity for this critical component.
Highest Accuracy and Quality
While creating your fabricated poly tank, we cut all plastic holding tank components with the latest in CNC equipment, and use only Virgin U.S. material to ensure the absolute highest quality. This accuracy and quality is repeated on every custom plastic polyethylene tank for consistent operation and reliable function.

- High tensile strength
- Impact resistant
- High compressive strength
- Excellent dielectric properties
- Resists most alkalis and acids
- Resists stress cracking
- Retains stiffness and flexibility
- Low moisture absorption
- Non-toxic
- Non-staining
- Easily fabricated
- High heat resistance
There are 2 Polyethylene grades which can be welded: Low Density (LDPE) or High Density (HDPE)
- LDPE Polyethylene: Frequently used for plastic tank applications where mobility without stress fatigue is desired.
- HDPE Polyethylene: Non-toxic and non-staining; Meets FDA and USDA certification for food processing
Regardless of the size and performance requirements, Miller Plastics has the expertise to manufacture custom polyethylene tanks to meet even the most demanding application challenges.
