plastic vials

MGC’s new multilayer advanced material,
OXYCAPT™, integrates the best of plastic and
glass for plastic vials

What is OXYCAPT™?The best of glass and plastic, without the drawbacks

Traditional glass and plastic materials for syringes and vials are filled with problems. Glass suffers from a range of issues—such as high-breakability and poor PH stability—while plastic has an insufficient oxygen barrier and UV barrier. The US FDA and pharmaceutical companies have searched for solutions. Competitors have launched advanced material products, but their imperfect oxygen barriers and stability have been met with criticism.

This led to the creation of OXYCAPT™—MGC’s new, lightweight, multilayer material, with all the benefits of glass and plastic.

MGC’s OXYCAPT™ unites the best qualities of glass and plastic in a three-tiered, multilayer, advanced material that features an excellent water vapor barrier & drug contact layer made from COP (Cyclo Olefin Polymer) and an oxygen barrier layer with an oxygen barrier polymer. With low extractables, low protein absorption, and low breakability, all components come together to produce the best high oxygen barrier material on the market.

Why it’s betterA breakthrough in longer-lasting, safer medications

OXYCAPT™ provides high oxygen barrier —along with the low inorganic extractables, low breakability, and lightweight properties of plastic. Inorganic low molecular extractables are below that of Type I glass. Excellent UV absorption means drugs last longer, with improved stability and efficacy throughout their lifespan.

Also for biologics and biosimilars, OXYCAPT™’s low extractables, high-breakage resistance, and high oxygen barrier—plus an improved UV barrier that absorbs UV and preserves drugs longer—make it the best, advanced material. Pharmaceutical companies with epinephrine, gene/cell therapies or emergency drugs like dopamine will also see benefits.

OXYCAPT™ in useThe best choice for plastic vial use

MGC’s OXYCAPT™ plastic vials are the right solution for parenteral pharmaceutical liquid medication storage. OXYCAPT™’s multilayer construction preserves drug stability and shelf life in plastic vials, with significantly reduced oxidation, compared to COP. Long-term trials find OXYCAPT™ eliminates the problem of delamination (visible small flakes and particles from glass deterioration over time) in glass, while maintaining its oxygen barrier. OXYCAPT™ also resolves poor stability and low visibility issues found in plastics.

The OXYCAPT™ AdvantageOutperforming plastic with superior material

Oxygen Barrier

OXYCAPT™-P Vial has high oxygen barrier property. The oxygen permeability is about 14 times better than COP. The result ensures consumers, pharmaceutical companies, biopharmaceutical companies, and entrepreneurial ventures looking to deliver biosimilars and biomedicines of advanced biologics, receive effective medication after longer periods of storage time.

UV Barrier

Pharmaceutical companies heavily focus on improving UV barriers of packaging container materials because UV deteriorates drug contents and stability. Through UV absorption, OXYCAPT™ protects drugs better than COP and Glass Type I by cutting off UV light below 300 nm.

Inorganic Extractables

Increased scrutiny by regulators has led the medical, pharmaceutical and biopharmaceutical industry to focus on inorganic extractable assessments to ensure patient safety and drug interaction. OXYCAPT™ outperforms all plastic and glass advanced materials—including Type 1 Glass, COP, PP, and PE—currently on the market.
