  • 4Expert Guidance at Every Step

    The technologies neededto create a cost-effectiveproduction system mustbe carefully balanced.In all cases, BattenfeldGloucesters blown filmprofessionals have theexperience to guide youto the right choices for:

    Systems that Growwith You

    Material feeding andblendingExtruder size andscrew design Single or multilayer,low profile, stationaryor oscillating dies Air rings and internalbubble cooling (IBC)

    New markets andapplications for plasticfilms are developing allthe time. As a result,innovative materialsand film structures arecontinually introducedto keep pace withmarket demand.

    High-performance films for challenging processes

    Consistency in theProduction of FlatFilms

    Production of high-qualityfilm requires that everycomponent in the systemworks together. One ofthe most important stepsin this process requiresthe extruder to feed ahigh-quality melt at highvolume. To assure this,our exclusive Variable

    Lead Barrier Screw wasdeveloped for both oursmooth bore and grooved feed extruders.The VLB design provideshigh output and a consistently uniform meltacross a wide range ofpolymers.

    Rugged construction guarantees high-quality rolls

    Superior quality filmssuch as those used inlamination, metallizing,printing and otherconverting operationsare produced understrict specifications,and demand a highly

    controlled process. Forinstance, heated aircarelessly vented froman extruder can causefluctuations in thetemperature aroundthe bubble, which cancause gauge bands in

    Targeting from Automatic Packaging to High Barrier Applications

    This maximizesuniform flowdistribution for tightgauge control. Anoptimized shear rate is

    generated along thechannels to preventcarbon buildup or gelformation, speeding upproduct changeovers.

    All die components aremachined from highestaircraft grade drop-forged, through-hardened, and uniformlystress-relieved alloy steelto prevent distortionduring heat and coolcycles. The mass ofeach component isoptimized to providethermal homogeneityand maximum deflectionresistance throughout

    the die. The result isdimensional stabilityyielding exceptionallyuniform flow rate andsuperb gauge control.For maximum uptime,Gloucesters innovativetaper-lock, self-aligningdie parts can beassembled anddisassembled quicklyand easily at thecustomers plant; andthe die diameter and

    die gap can bechanged withoutchanging the entiredie. All flow surfacesare electroless nickel-plated as standard toresist abrasion andcorrosion; alternativecoatings are also available.
