A system includes a source of sheet material and a conversion machine. The conversion machine is configured to receive the sheet material and to form the sheet material into a fill material. The conversion machine further includes a cutting system configured to selectively cut the fill material either partially or completely to form two pieces of the fill material. When the cutting system partially cuts the fill material, uncut portions of the fill material remain between the two pieces of the fill material. When the cutting system completely cuts the fill material, no uncut portions remain between the two pieces of the fill material.

A system () for closing mailers includes a forming funnel () and a fusing device (). The forming funnel includes funneling surfaces that receive an opening of a mailer in an insertion direction () and constrain the opening of the mailer after the opening of the mailer is inserted. The funneling surfaces are arranged to continue constraining the opening of the mailer as the mailer moves in a sliding direction (). The fusing device includes a slot that receives the constrained opening of the mailer from the forming funnel. The fusing device applies pressure and heat to the opening of the mailer as the opening of the mailer moves through the slot. The pressure and the heat applied by the fusing device cause portions of the opening to fuse together to close the mailer.

A dispenser () includes a supply structure () and a biasing structure (). The supply structure holds mailers (). A mailer from the mailers includes a first wall and a second wall. The first and second walls are closed at a first side of the mailer, closed at a second side of the mailer, and closed at a closed end of the mailer. The first and second walls are not closed at an open end of the mailer. The mailer is arranged to be dispensed from the supply structure (). The biasing structure () is arranged to engage the mailer as the mailer is dispensed from the supply structure (). The biasing structure () has narrowing surfaces configured to contact the sides of the mailer as the mailer is dispensed. The narrowing surfaces of the biasing structure () are arranged to narrow the open end of the mailer thereby causing the open end to be biased open.
