Bottle Wall
Oxygen passing through PET walls can influence oxygen-sensitive products during storage. OxyBLO2 is positioned to help block external oxygen and protect the packed drink over time.

OxyBLO2 PET Oxygen Barrier for Beverage Bottles
When a beverage packaging oxygen barrier solution must protect flavor, aroma and bottle appearance, OxyBLO2 gives packaging teams a focused active scavenger route. Work with an active oxygen scavenger manufacturer to match PET grade, filling method and shelf-life expectations before specifying the additive direction.

Start With How Oxygen Reaches The Beverage
PET packaging decisions become clearer when the team separates the oxygen paths, the beverage sensitivity and the bottle appearance target.
Headspace
Oxygen remaining above the liquid can continue reacting after sealing. Active scavenging helps reduce that oxygen load before it affects flavor, aroma or color.
Liquid
Juice, tea and functional drinks can lose sensory and nutritional quality when oxygen remains in the product system. Package design should account for the beverage itself, not only the bottle.
Variant boundary
Match The OxyBLO2 Direction To The Packaging Target
The OxyBLO2 series works best as a tailored packaging choice rather than a single universal additive. The strongest inquiry starts by naming the protection window, PET process and visual requirements.
USO-1002A
For PET bottle projects that need active oxygen absorption while keeping production straightforward.
- No prior activation requirement.
- Compatible with PET grade use described by ColorWay.
- Works with existing single-layer injection molding equipment.
- Built for oxygen absorption while maintaining bottle transparency.
USO-1001P
For beverage packaging programs that need stronger oxygen barrier and absorption performance.
- Designed for enhanced oxygen defense.
- Useful when longer shelf-life protection is part of the packaging brief.
- Presented with minimal impact on transparency.
- Best discussed with bottle thickness, dosage and storage context.

Keep The Packaging Conversation Tied To The Beverage
Oxygen protection is not a one-line specification. The drink type, filling route and visual standard shape the first technical conversation.
| Packaging case | Oxygen concern | OxyBLO2 discussion point | Buyer note |
|---|---|---|---|
| Juice PET bottles | Flavor, color and nutrient stability can be sensitive to oxygen. | Review internal oxygen absorption and external oxygen blocking together. | Prepare formula sensitivity and target shelf-life expectations. |
| Tea packaging | Aroma and color can change across storage and distribution. | Balance oxygen protection with bottle clarity and brand presentation. | Share storage route and retail display conditions. |
| Functional beverages | Oxygen may affect delicate ingredients and sensory quality. | Discuss whether the project needs standard or enhanced OxyBLO2 protection. | Send ingredient sensitivity and expected protection window. |
| Aseptic PET bottles | Protection must support both oxygen control and bottle appearance. | OxyBLO2 can support cold and hot aseptic filling applications. | Clarify filling temperature, process route and delamination concerns. |

Questions To Settle Before The Packaging Trial
What does OxyBLO2 do in PET beverage bottles?
OxyBLO2 is an active oxygen scavenger for PET beverage packaging. It helps block oxygen entering from outside the bottle and absorb oxygen from the bottle wall, headspace and liquid.
Which beverages are a strong fit for active oxygen protection?
Juice, tea and functional beverages are strong candidates because oxygen can affect flavor, color, aroma and nutritional quality during storage and distribution.
How do USO-1002A and USO-1001P differ?
USO-1002A is positioned for no-activation PET use with existing single-layer injection molding. USO-1001P is positioned for enhanced oxygen barrier and absorption when a longer protection window is needed.
Can OxyBLO2 support aseptic filling projects?
Yes. OxyBLO2 can support both cold and hot aseptic filling applications where PET bottle oxygen protection must work with bottle appearance requirements.
What affects oxygen absorption performance?
Additive amount, bottle thickness and storage conditions can affect absorption efficiency and PET packaging performance.
What should a packaging team send before asking for a recommendation?
Share the beverage type, PET grade, bottle structure, filling method, target shelf-life window, transparency expectations and storage conditions so ColorWay can discuss the right OxyBLO2 direction.
