Co-injected Medical Bottles

Enabling the Conversion from Glass to Plastic in Medical Applications

Mold-Masters Co-injection Multi-Layer Technology is enabling the conversion from glass to plastic in medical packaging applications. A plastic container is lighter than glass and resists breakage which reduces the risk of losing bio-samples and exposing healthcare personnel to infectious substances. Normally one would assume that switching to plastic is a straightforward application, but because medical containers are required to carry various samples and cultures for testing, they must also meet the necessary preservation standards. As a result, plastic containers converting from glass must incorporate high-performance gas and moisture barriers.

For example, Mold-Masters Multi-Layer Co-injection technology was used to produce blood culture collection bottles and vials which enabled the switch from glass to a plastic alternative. The bottles were able to be used by healthcare professionals concurrently with glass versions to aid in the conversion process. The plastic bottles have been validated by all laboratories who stated that there was no difference in organism yield and time to positivity. Collection procedures, safety adapters, collection and volumes all remained the same as its glass predecessor. 

Mold-Masters Co-injection Multi-Layer Technology allows two different resins to be combined into a single 3-layer melt stream without any penalty to cycle time or production volume. Our systems are compatible with various High-Performance Barrier materials suitable for a range of medical packaging applications that enable the conversion from glass to plastic.
