Applications - Bottles

High gas barrier bottles

By using Nichigo G-Polymer as a middle layer, multilayer bottles with high gas barrier performance can be made.
As an adhesive resin, maleic anhydride modifed PO can be used.


Features of emulsions that use Nichigo G-Polymer

Acrylic emulsions that use Nichigo G-Polymer have the following features.

  • Stable emulsification polymerization is possible with a wide range of monomer compositions
  • Excellent mechanical stability, chemical stability, pigment mixture stability, freezing and melting stability, and low temperature viscosity stability 
  • Strong adhesion with hydrophilic materials
  • Forms tough films with excellent solvent resistance 
  • Water resistance can be increased when used with crosslinking agents 
  • Possible to manufacture powder emulsions that can be re-emulsified

Recommended grades

*1: Measured using the DSC method
*2: 2160 gf at 210oC

Oxygen permeability

Co-PET multilayer bottles with Nichigo G-Polymer as a middle layer have high gas barrier performance that is 3 times that of single layer co-PET bottles.
Furthermore, by placing a Nichigo G-Polymer layer on the outside, gas barrier performance that is 50 times higher can be achieved.
