Laminating Films

Who is better to design your laminating film line than the folks that build 2000 fpm lamination machines. Davis-Standard Converting Systems leads the industry in flexible packaging and knows the needs for blown film systems to serve high speed converting machinery lines. This is especially true in the area of laminating films where the roll geometry and uniformity of the thickness and especially each layer leads to fast conversion speeds on converting and laminating lines. Consistency in output and low melt temperatures from the extruders are vital. The unique extrusion concept leads to the best and most consistent melt quality (temperature uniformity to 2 degrees F and pressure variation < 1%) which is necessary to get uniformity across all layers. Uniform layers allow for thinner layers of expensive materials and DS lines produce the best economic coex structures. The die systems are stationary up to 1000 mm diameter. Oscillating haul-offs and roller collapsing frames produce flat, smooth film and rolls. These systems produce symmetric and asymmetric films.

• Super Air Cooled MAC extruders utilize the single high volume suction blower concept for cooling. Low maintenance.
• Pre-wired control panels mounted on extruder bases reduce installation time.
• DSB II screws in special diameters of 75mm, 90 mm, 100mm, 115 mm and 1300mm provide uniform high output of PP, LLD/LD, HD, EVA and blends. Best MD variation in industry leads to thinner barrier layers.
• Lo-Pro dies allow for easy operator access and excellent uniformity to <5% before auto adjustment.
• WesJet air rings and IBC provide high cooling rates and increased bubble stability.
• WesJet AutoPro air rings cut the gauge variation in half.
• Collapsing frames can be wood, covered slats or roller with partial of full gussets.
• Surface winders for large roll diameters
• Turret winders can be shafted or shaftless and come with gap winding feature
• Full roll carts and shaft handling are available
