What is Excevier™

• Organic-inorganic hybrid aqueous coating agent
• Delivers excellent gas-barrier properties achieved by coating then drying
• High aroma retention, solvent resistance and transparency in addition to oxygen and water vapor gas barrier properties
• Wide range of applications, from vacuum molding and stretch blow molding to non-molding use (film or metal)

Caution

Coating usage

Please prevent from using Excevier™ at innermost or outermost layer of multi layer composition of the container, sheet or film, since it is water soluble material. Use a top layer or perform resin-film dry lamination as shown in the examples(① and ②) below.
