HyGuard Oxygen Scavenging System

Oxygen scavenger system HyGuard is ColorMatrix’s game-changing oxygen barrier system, engineered to enable fully recyclable, fully protective PET packaging for oxygen sensitive beverages and foods.

This revolutionary new technology will allow significant advances to be made to the sustainability of the global PET packaging industry and is the first and only oxygen scavenger to deliver:

HyGuard® oxygen barrier innovation

Perfect container clarity

Unlike conventional oxygen scavengers, HyGuard requires nothing in the container wall that could cause haze leaving a perfectly clear appearance

Full recyclability

HyGuard oxygen scavenger containers are the only containers suitable for bottle to bottle recyclability.

HyGuard is the first oxygen scavenging technology to be recognised by both the EPBP (European PET Bottle Platform) and the APR (Association of Plastics Recyclers) as having no negative impact on recyclability.

Fully controllable shelf life

HyGuard is activated only once the container closure is applied allowing maximum longevity in preform/container storage. Shelf life can be adjusted and controlled according to specific applications up to and beyond 24 months if required.

HyGuard will open up new opportunities for the global PET packaging industry:

Container light-weighting and reduced portion size

HyGuard can be combined with other additive technologies such as UV protection where required without compromising performance.Thinner and smaller PET containers require greater protection from oxygen ingress and the impact on cost and container clarity can make these options unviable.  As a catalytic system, HyGuard requires no adjustment to the level of material used. The same ppm of catalyst is used whatever the level of protection required opening up new opportunities for container light weighting and reduced container portion sizes. HyGuard delivers increased product protection without impacting container clarity and recyclability.

Additive combination

HyGuard can be combined with other additive technologies such as UV protection where required without compromising performance.

Availability

As the leading global innovator of plastic colorants and additives, ColorMatrix’s R&D team has developed HyGuard in partnership with a number of key global PET industry players, and will be making the technology available under licence through these preferred partner companies.
