Featuring in-line air bubble extrusion and multi-layered lamination

Cast film extrusion lines are recognized in the industry for their high production speed and film quality featuring superb optical characteristics. Alpha Marathon’s cast film lines complement these benefits with exception versatility as these lines can be used for applications ranging from general packaging to food applications. This range of flexibility is increased with in-line processing such as air bubble extrusion and multi-layer lamination the flexibility which Alpha Marathon offers. The addition of these units simplify the process and reduces the footprint and cost of machinery as off-line processing is eliminated.

Air Bubble Packaging

Air bubble packaging is commonly used as a layer of protection for the packaging industry. Alpha Marathon has incorporated the production of air bubble packaging as an in-line process for cast film lines. This is achieved by utilizing dual extruders each feeding a separate die. One side of the film is heated in a vacuum mould forming the bubble and then the two layers are sealed together. The size of the bubble ranges from 1/8" to 1/2" but we also offer custom air bubble sizes according to your specifications. These Alpha Marathon lines are able to produce air bubble packaging up to 124" wide at a speed of up to 200 fpm.
