Density and Crystallinity Grading of Polyethylene Packaging

Ensure incoming polymer film barrier properties and density grading using rapid reflectance scans.

Polymer Film Quality Control

B2B chemical packaging films must meet strict thickness, density, and crystallinity specifications to guarantee chemical resistance and barrier properties. Differentiating between High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), and Linear Low-Density Polyethylene (LLDPE) on warehouse floors is critical to prevent contamination.

Rapid Quality Verification

Using USTECH handheld reflectance spectrometers, operators scan incoming rolls of packaging film. The system calculates density and barrier properties in seconds, ensuring material specifications are met.
