Carestream Health said Tuesday it's again boosting prices worldwide for X-ray and other medical, dental and industrial film stock in the second general price hike in a matter of months as the company says it faces rising commodity costs.

Rochester, N.Y.-based Carestream blamed the price hike on the skyrocketing costs of raw materials used to manufacture film, especially silver. As of Tuesday afternoon, silver was trading at $29.79 an ounce, up 76 percent from the beginning of the year and near a three-decade high.

Carestream announced a price hike on film in August, which was its first general price increase in nearly three years.
