• Don't uniformly/globally remove glass; loading stresses vary by specific bottle region and glass removal must be strategically targeted.
• Don't heavily restrict the bottle dimensions; there must be sufficient flexibility to allow for adjustments of volume/capacity values.
• Don't make the design overly complex and intricate; more cosmetic features equates to fewer opportunities for lightweighting.
• Don't ignore the importance of using Finite Element Analysis (FEA) to guide the lightweighting process; removal of glass without knowledge can result in either missed opportunity or unacceptable performance degradation.
• Do think outside the current boundaries and specification limitations for glass container designs.
• Do understand that lightweighting glass containers should also include the optimization of filling lines.
• Do combine the use of modern Hot End process control equipment with sound GMPs to achieve the best results.
• Do develop a partnership between the glass manufacturer and the filler to ensure acceptance and success.
• Do lightweight first — initiating the process on a new design, prior to first manufacture saves time and money.
