Which of the following is NOT a common casket material used in funeral merchandising?

In the context of funeral merchandising, plastic is not a common material used for caskets, making it the correct choice in this scenario. Traditionally, caskets are predominantly made from wood or metal, reflecting the longstanding preferences and practices within the industry. Wood caskets, such as those crafted from hardwoods like oak or cherry, are valued for their natural beauty and craftsmanship. Metal caskets, often constructed from materials like steel or bronze, provide durability and have a long history in funeral services.

Biodegradable materials are gaining traction in response to environmental concerns, leading to innovations in casket design that prioritize sustainability. However, plastic does not generally fit the traditional expectations associated with casket materials, which are typically selected for their aesthetic and structural qualities rather than the characteristics of plastic. Using plastic may not convey the same sense of reverence and tradition commonly sought after in funeral settings.
