A child resistant paperboard tube is a type of packaging used to store and protect products such as medications, vitamins, and other small items. It is designed to be difficult for children to open and to be child-resistant. The tube is usually made from paperboard or cardboard, and is often lined with a plastic or foil liner to protect the contents from moisture and air. The tube is typically sealed with a child-resistant cap, which is designed to be difficult for children to open. The tube may also include additional features such as a tamper-evident seal or label to help ensure the product is not tampered with.
