Protection, Packaging, Hygiene Films – Leading Technology for Your Cast Film Needs

As an industry leader in cast film technology for applications in food packaging, personal care markets and stretch/cling films, our product portfolio is extensive. Our knowledge of multi-layer structures and MDO (machine direction orientation) coupled with innovative dies and winders, high efficiency cooling rolls and superior control technology enable us to support customers worldwide. Our equipment is designed to reduce scrap and improve processing rates while producing cast and cast embossed films with excellent tensile strength and barrier properties. Let us add value to your cast film operation.


We support several 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 (micro layers). 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.

  • 80 inches / 2 meters - 4 rolls up
  • 100 inches/ 2.5 meters - 5 rolls up
  • 120 inches / 3 meters - 6 rolls up
  • 160 inches / 4 meters - 8 rolls up
  • 180 inches / 4.5 meters - 9 rolls up
  • 200 inches / 5 meters - 10 rolls up

Typically, all lines are geared in to run at speeds up to 2300 fpm/700 mpm. However, actual line speeds may be limited by resin formulation, resin quality, line size or winding system.

NEW TO THE INDUSTRY! The optimized dsX s-tretch™ pre-stretch cast film extrusion line is the first in-line pre-stretch system enabling customers to run thinner films at higher speeds. This line enables stretch film providers to produce consistent, high-quality pre-stretch film with greater efficiency. The two-meter wide line also has the advantage of a smaller footprint, yet allows for growth.

Typical Specifications

Net Widths 2 to 5 meters 80 to 200 inches
Line Speeds 457 to 700 mpm 1500 to 2300 fpm

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.

Typical Specifications

Net Widths 2 to 5.3 meters 6.5 to 17 feet
Thickness 15 to 150 micron .6 to 6 mil
Net Output 500 to 2300 kg/hr 1100 to 5000 lbs/hr
Speeds 150 to 250 mpm 492 to 820 fpm
Winding Diameter 750 to 1200 mm 29.5 to 47.2 inches

 

This is a significant cast film area for Davis-Standard. Mono and coextruded systems are available as well as film forming using the wet or dry embossing method as determined by product requirements. Repeatable embossing patterns and low-tension capabilities provide excellent winding performance. In-line slitting down to 3 inches (76mm) are possible with our advanced winding systems. Specialty lines can incorporate coating or lamination of lightweight non-woven substrates. We often provide custom equipment or configurations to meet specific product requirements.

  • Core diameters of 3 to 6 inches (76 to 152.4mm) are possible using specially designed winding systems for all line widths
  • Typical line speeds of 600 to 1400 fpm (80 to 425 mpm) depending on extrusion package, formulation, film properties, embossing method and selected winding options

End products include baby diapers, protective and masking films, disposable garments and bed sheets, pouches, PP photo protective sleeves, shower curtains and tablecloths.

Typical Specifications

Widths 2133 to 3353 mm 84 to 132 inches
Line Speeds 80 to 425 mpm 600 to 1400 fpm
Winder 1 meter in diameter Up to 40 inches in diameter

 

Davis-Standard offers configurations for producing flat cast barrier structures for consumer and medical packaging. Systems are designed based on end use requirements. Advantages include the processing of structures with singular or multiple layers and flexibility to incorporate enhanced barrier properties using nano technology. Our extruders and feedscrew designs offer excellent melt quality and thermal forming pressure stability.

Typical Specifications

Net Widths 2 to 2.7 meters 78.7 to 106.3 inches
Thickness 50 to 300 micron 2 to 12 mil
Net Output 750 to 1600 kg/hr 1653.5 to 3527.4 lbs/hr
Speeds 15 to 150 mpm 49.2 to 492.1 fpm
Winding Diameter 750 to 1200 mm 29.5 to 47.2 inches

 

Within this category, our cast film lines encompass three to five extruders for producing a variety of packaging films up to seven layers. These films are generally formed with a vacuum box, are corona treated have in-line slitting using bleed trims, and wound with low tension. These films also typically have a heat-seal side and a packaging-machine side where different slip levels are required.
 
Typical products are in the 1 to 4 mil (25 to 100 micron) range. Products include confectionary bags, bread bags, towel and tissue bags, single slice cheese film, pouch film, sugar bags, meat packaging, electrical component packaging, liquid packaging, vacuum packaging films and bag in a box film.
 
Typical Specifications
