Plastic container maker Inline Plastics Corp. has increased manufacturing capacity at its Connecticut location by up to 10 million containers per month.

The Shelton, Conn.-based company installed the high-speed thermoforming equipment in late December, according to a news release.

Inline plans to hire up to 18 employees to support the new line.

The Connecticut Department of Economic and Community Development and the Connecticut Development Authority helped finance the addition, according to the release.
