Identifying Problems

Identifying the causes of slow line speeds and down-time can be difficult.  Resolution of package related customer complaints can be challenging.  


Precise Packaging Services offers detailed lab analysis to resolve problems with:

  • Cocked caps
  • No caps
  • Slow feeding
  • Loose caps
  • Cracks
  • Bulging / collapsing side walls
  • Leakers
  • Bad welds
  • Liner incompatibility 

Laboratory Testing

Our lab equipment includes an optical comparator for precision measurment, microscopes both digital and 7X binocular, melt flow indexer for plastics analysis, automatic and manual closure torque measurement meters, submersion leak chamber, vacuum chambers, digital scales and a variety of hand held measurement tools. Photographic and video documentation of testing can be provided as requested.


Our lab can perform the following evaluations on your packaging samples:

  • FDA/EPA/DOT Standards Compliance Testing
  • Bottle finish analysis (T,E, I, H, ovality, CR function)
  • Consistency and conformance to specifications
  • Cap and bottle analysis
  • Vacuum Chamber leak test up to 1 Liter size
  • Internal pressure testing (any size package)
  • Induction Seal integrity
  • Photo microscopy (find liner pinholes, etc)
  • Cross section analysis
  • Gram weigh checks
  • Functional Testing including 
  • Torque Testing
  • Leak
  • Pressure Decay
  • Liner Compatibility
  • Dimensional Layout
