Bagging Film
Four Important Cost Considerations: The price of vacuum bags is influenced not only by the composition of the film but also by four other factors: thickness, width, length, and packaging. 1. Thickness. Films with a thickness of 3 mil have a higher cost compared to those with a thickness of 2 mil due to the increased quantity of raw material per square meter. 2. Width. Films with widths exceeding 8 to 10 meters require specialized manufacturing and handling equipment, which may result in higher prices in some cases. 3. Length. Film rolls with short lengths cannot be manufactured directly on the blown film extrusion line, leading to increased costs due to secondary operations. 4. Packaging. The price may vary depending on the packaging method, as outlined to the right.

Available in 2 mil thicknesses up to 3.6 meters wide in standard sheet, v-sheet and lay flat tube formats. * Application is feasible but necessitates validation on a case-by-case basis, primarily considering factors such as temperature and resin type. ** For tube format film (LFT), the width in inches is measured as the envelope’s width, which can be unfolded to double the size.
