The Monolayer Barrier
• PolyShieldTM is a PET barrier resin which provides excellent oxygen and carbon dioxide barrier in combination with outstanding clarity for tinted bottles when blended with MXD6 at the injection machine– PET - MXD6 blend
– Monolayer bottles
– Active O2 scavenging
– Passive CO2 barrier
– Excellent clarity
![Page 11: Beer-in-PolyShield-Drinktec-3.pdf](https://reader034.fdocuments.in/reader034/viewer/2022052701/563db89a550346aa9a953242/html5/thumbnails/11.jpg)

• Oxygen ingress detection
• Bottles filled with gel indicator
• Oxygen turns the indicator blue
• Oxygen ingress can be located
• Oxygen ingress can be quantified
