Packaging advice

Drawing on decades of packaging expertise and an industry-unique chemical compatibility database containing over 50 years of packaging advice, our in-house chemists are available to support you in finding the most suitable packaging, lining, and closures for your packed product.

What can we offer

With your product’s MSDS or formulation, our chemists can often directly recommend the most suitable closure, lining and packaging by consulting our database. If the information is incomplete or in case the product is not in our database, we can perform in-house tests with a 250 ml product sample.

What we need to know

  • What product is packed*
  • Specific chemical name and/or trade names
  • components and their concentrations including water content
  • Density, vapour pressure, boiling / melting point, viscosity, pH, etc.
  • Filling / emptying temperatures
  • Storage conditions and desired shelf life
