Blown Film

Davis-Standard supplies blown film extruders, extrusion lines and associated winders, dies and feedscrews for blown film processors around the globe. Our mono and multi-layer blown film technology is used for applications ranging from agriculture and greenhouse films, to packaging and shrink films, to stretch and collation films. Brampton Engineering, a blown film technology company for over 45 years that became a Davis-Standard company in 2018, is a leading provider of multi-layer AeroFrost® air blown and AquaFrost® water quenched film systems, film winding and many other film production solutions, particularly for food packaging.

In addition, to complete lines for co-extruded film up to 11 layers, the first water quenched film lines, and blown film lines for products up to 25m in circumference, we offer the widest range of components in the industry.

For new lines or retrofits, choose from SCD 4.0 pancake dies, Vertex side-fed cylindrical dies, Optiflow or Centrex center-fed cylindrical dies, with die lip diameters ranging from 4” to 100”.

Our portfolio of air rings includes WesJet dual lip, UpJet elevated dual lip and the newest Vector® single-inlet air ring with patent-pending Vector® dual lip for the easiest and most repeatable setups.

In addition to the proven Davis-Standard control systems, Brampton Engineering offers the ITALYCS® 5 line control system designed specifically for multi-layer blown film and AquaFrost®. Likewise, Brampton Engineering adds the FlexWin winder line to the extensive selection of winders offered by Davis-Standard.

Whether for innovative food packaging films, construction and agriculture stretch films, medical and hygiene barrier films, industrial films and bags for heavy-duty applications or flexible packaging, Davis-Standard and Brampton engineering blown film capabilities are unsurpassed.

Industrial Films & Bags

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. Typical Specifications

Barrier Films

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.

Laminating Films

Davis-Standard is a global extrusion leader in flexible packaging with lamination lines capable of 2000 feet per minute. We understand the needs for high-speed converting machinery, especially in the area of laminating films where roll geometry and layer uniformity leads to faster speeds on converting and laminating lines. Uniform layers enable cost-efficient use of expensive materials, and our lines have been effective in producing economical coex structures. Advantages such as stationary die systems, oscillating haul-offs, and roller-collapsing frames produce flat, smooth film and rolls. Our systems are also known for consistent symmetric and asymmetric films.

Stretch Films

Davis-Standard understands stretch wrap systems. Whether cast or blown film, our technology is applied to all components. Roll geometry and unique small roll winders efficiently allow for high production rates by providing reliable, consistent automated roll handling. Die systems are stationary up to 1-meter in diameter. Oscillating haul-offs and roller collapsing frames produce flat, smooth film and rolls. Oscillating die and stationary haul-offs are also available. These systems produce symmetric and asymmetric films.

Specific to agricultural stretch films, our technology is focused on uniform quality and thickness. This provides excellent stretch properties with consistent cling levels, strong puncture resistance, high load retention for bale integrity, low oxygen and water permeability.

Food Packaging

Food Packaging

Brampton Engineering has specialized in multi-layer co-extrusion AeroFrost® film systems for over 45 years. The flat pancake-style SCD® 4.0 die offers not only the lowest residence times for the middle and outer layers and the fastest resin changeovers, but can also be customized with thermal isolation between layers to minimize overheating thermally sensitive resins such as EVOH in proximity to much hotter nylon layers in high-barrier film structures. Paired with the Vector® air ring and ITALYCS® control system, SCD is the most flexible die choice for making a wide range of different film structures with fast job changeovers and less frequent die cleaning.
