TechII, located in Springfield, Ohio, is a manufacturer of injection-molded products, extruded sheet, and thermoformed products. It uses plasma-enhanced chemical vapor deposition to coat the inside of thermoformed PP buckets with a thin layer of silica (glass). The glass layer is only a few nanometers thick, but it can give the packaging extremely high oxygen and vapor barrier properties. In the past, vapor deposition technology was used in PET bottles, but Shiffer, the president of TechII, believes this is the first time it has been applied to thermoformed PP containers.
Shiffer said that the packaging is still in the research and development stage, but once commercialized, it will achieve what he calls the "Holy Grail" of plastic packaging, with barrier properties comparable to those of glass and metal containers. Shiffer indicated that in some cases, with this packaging, food companies can use less preservatives to improve flavor and freshness.
The significance of barrier packaging is beyond doubt. What matters is what process we choose to achieve it. In fact, while choosing barrier layers such as EVOH and nylon, how to better combine the characteristics of traditional high-barrier materials like glass and metal with new plastic materials might be a direction we can consider when developing high-barrier products. The key is to balance processing efficiency and barrier performance.
