unprinted roll stock of various Mylar structures

Rollstock refers to long unbroken printed or unprinted flexible film sold on rolls. Rollstock is used for a wide range of applications, most commonly it is a key packaging material component to automatic VFFS and HFFS equipment (Vertical and Horizontal Form Fill Seal machines). They can also be used in a number of manual applications to create bags of any size or shape using heat sealers.

IMPAK has a selection of 53 materials on the floor, available in rolls from 24 to 51 inches wide and as much as 6,000 feet long.

What is FFS?

FFS stands for "Form Fill Seal." These automated systems take laminate film rollstock and use it to create, fill, and seal pouches with product quickly and easily. Invented in 1936, these machines are widely used around the world, and are available in vertical (VFFS) and horizontal (HFFS) varieties.
