DuPont packaging resins allow beverage plastic closures and lids to seal tightly and open more easily.  

DuPont™ Elvax® packaging resins maintain outstanding seals around the entire cap to preserve flavor and carbonation, prevent leaks, and provide clear evidence of any tampering. And DuPont™ Appeel® lidding resins provide strong, durable seals, yet remain easy to peel.

Drawing on its global expertise and long history of packaging innovations, DuPont works with packaging converters, manufacturers, and brand owners to match form and function in plastic closures for bottles and cups, from store labels to upscale water brands.

DuPont™ Elvax®  for Plastic Cap Linings

DuPont™ Elvax® ethylene vinyl acetate copolymer resins are available in a wide range of packaging film and coating grades. Cap liners made with Elvax® deliver:

  • Consistent hermetic seals for greater protection against leaks
  • Better flavor preservation and carbonation retention due to good water vapor and gas barrier properties
  • Tamper-evident protection for consumers
  • Easy-open caps through the reduction of removal torque
  • Prevention of unwanted tastes for longer shelf life and greater consumer satisfaction
  • Easy processing at low temperatures results in trouble-free processing
  • Cost savings compared to alternative compounded liner materials

With Elvax®, the bottle necks remain clean and clear. Unlike other compounded liner materials, Elvax® contains no mineral oil, which can mix with beverages and deposit a ring of unsightly brown residue on the inside of the bottle’s neck.

DuPont™ Elvax®  for Metal Beverage Crowns

Elvax®-based applications also meet growing market demand for halogen-free and plasticizer-free liners in metal crowns used in bottling water and carbonated soft drinks. The benefits of using Elvax® are many:

  • FDA approval for direct contact with food and beverages
  • Tight and effective container sealing
  • Easy processing (high productivity on SACMI molding lines)
  • Excellent carbonation retention
  • Consistent lot-to-lot quality
  • Formula and performance approved for water and CSD
  • Halogen-free compound
  • No adverse after taste is transferred to the beverage, a particular concern for taste-sensitive bottled mineral waters

DuPont™ Appeel®  for Easy-to-Peel Cup Lids

DuPont™ Appeel® peelable sealant resins combine tough, low-temperature sealability with excellent peelabilty and puncture resistance. Ideal for use in food service and frozen juice cups, Appeel® lidding resins provide:

  • Tough, low-temperature sealability with excellent clarity, flexibility, and impact & puncture resistance
  • Superior seal-through of liquid on cup rims to create strong seals that are easy to peel
  • Easy processing at low temperatures, providing trouble-free processing of cup lidding
  • One-bag convenience and consistency, assuring superior performance every time

Together DuPont™ Elvax® and DuPont™ Appeel® give beverage plastic closures and lids the sealing performance and integrity that everyone can raise a glass to.
