FPL 22 - Assessment of Common Carrier Shipping Environment - March 2015

An assessment of available data and information describing the common carrier shipping environment was conducted. The assessment included the major shipping hazards of shock, vibration, impact, temperature, and humidity associated with the handling, transportation, and warehousing operations of typical distribution cycles. Previous environmental studies and current data are reviewed and assessed for applicability to general type cargo design and/or evaluation. The data for each hazard are summarized in a format considered most useful to packaging engineers when such data are available.

Product Fragility Analysis Made Easy - March 2017

The Damage Boundary method of product fragility analysis has been around since the late 1960s and has proven itself to be an outstanding tool for reliability analysis, protective package design, and product fragility analysis. Yet it is not widely used in any of the areas where it can create a positive input. There are many possible reasons identified for this in the text. Possible different approaches and recommendations for procedure modifications are given in order to improve the effectiveness of product shock and vibration fragility assessment.

ASTM F3039 Dye Penetration Summary & Review - August 2014

ASTM subcommittee F02.40 has released a new standard to complement the package integrity testing standards already in use. The new standard, ASTM F3039 Standard Test Method for Detecting Leaks in Nonporous Packaging or Flexible Barrier Materials by Dye Penetration, is to be used for detection of edge seal channel leaks through a nonporous package equal to or greater than 50µm (0.002in). While the traditional ASTM F1929 Dye Penetration standard is used for porous packaging material, the ASTM F3039 is intended for nonporous packages – both transparent pouches such as nylon-nylon and opaque (foil-foil) packages.

Why Shipping Tests Don't Work - March 2017

“Shipping tests” or “trial shipments” are often used to determine if a product/package system will survive the distribution environment without damage to the product. The reality is that a single shipping test is statistically insignificant; utilizing this approach will often lead to incorrect conclusions unless further testing is conducted. This paper will explore the reasons for this while recommending a much more feasible approach to evaluating product/package systems.
