Davis-Standard, LLC products

Davis-Standard is the industry leader in developing innovative technology for large and wide blown film systems for industrial film and bag applications. There is no better blown film extruder for high output and low melt temperature than the MAC extruder with the DSB®II feedscrew. This extruder, specifically for blown film, leads to the best and most consistent melt quality (temperature uniformity to 2 degrees F and pressure variation <1%), which is necessary to achieve uniformity from large dies. Blown film die systems can oscillate up to 1.2 meters in diameter or remain stationary up to 2.1 meters in diameter. These systems produce controlled property films at wide widths with flat rolls. 

Davis-Standard`s blown film flexible packaging solutions for high-speed converting machinery lines are unsurpassed. This is especially true in the area of barrier films where roll geometry, thickness and layer uniformity lead to faster conversion speeds on pouch lines, FFS machines and laminating lines. Uniform layers enable cost-efficient use of expensive materials, and our blown film lines have proven effective in producing economical coextruded structures. Advantages such as stationary die systems, oscillating haul-offs, and roller-collapsing frames produce flat, smooth film and rolls. Our blown film systems are also known for consistent symmetric and asymmetric films.

We support several extruder configurations for hand and machine wrap applications. Co-extrusion systems are available to match line sizes with respect to desired layer percentages, film thicknesses and operating line speeds. We have capabilities for producing coextruded films from three to more than 30 layers (microlayers). The production of five layers using four extruders is the most common. Film forming is typically by vacuum box on a large diameter chill roll to control pre-stretch film properties. Winding systems feature fully automatic roll and core handling systems. Line sizes are available for net finished widths as listed below with the 120-inch/3-meter, 6-up line being the most popular and flexible.

Davis-Standard offers various configurations of extruders, filtration, feed-blocks and single or multi-manifold dies to produce CPP grades of lamination and metallisable cast films. The resins are processed on Davis-Standard barrier screws, with or without melt pumps, depending on application. A unique tandem extruder configuration is available for the heavy core layer. Three and five-layer co-extrusion configurations are available using a conventional feed-block or multi-manifold die technology.
