Lap seal wrappers place a nearly invisible overlap seal under the package making a very attractive package while using the minimum width film. Lap sealers use flat (single wound) film which is pulled over a forming plow, overlapped under the package and sealed by use of either a static or thermal seal. As the products flow through the former, they are encapsulated in a continuous tube of film and cut apart downstream by the end seal device. Lap sealers are most popular in applications which call for long runs of constant-sized products because each product requires: An individually-sized plow / A specific width of film to be stocked
