Alpha Marathon has developed, designed and produced numerous mono and co-ex blown film lines for agricultural and geo membrane applications.
Alpha provides the technology, experience and equipment to produce textured or smooth finish films.
Textured films can be produced with a smooth edge for welding purposes when sealing multiple sheets together on-site.
Agricultural and geo membrane films typically range from 10 mil up to 100 mil profile thickness.
Alpha has the capability to manufacture blown film dies up to 100" in diameter with downstream equipment to produce end-products over 7000mm in width.
Alpha's unfolders and side slitting capabilities deliver an open sheet to the winder for a finished roll product.
Depending on the composition, the membrane can be of potable or industrial grade, will have outstanding dimensional stability, high puncture resistance, possess chemical resistance, environmental stress cracking resistance, and have an ability to contour to surface abnormalities.
Alpha Marathon’s Cast Barrier lines are available from 5 to 11 layers and each line is capable to producing a variety of Barrier structures.
Line supplies with latest technology for Screw, Feedblock and Die design to improve quality and increase line output to provide the flexibility to meet the needs of our customers.
Alpha Marathon’s Barrier cast lines are designed to process various barrier materials included, EVOH, PA, encapsulated PVdc.
Applications for Barrier film are included medical packaging film and food packaging (fresh meat, dairy product, frozen meals, milk and etc.) as well as for laminating to other film or sheet.

Alpha Marathon's Patented "Layer Sequence Repeater" Production Die
After introducing its patented Nanolayer capable Die Technology at NPE 2012, Alpha Marathon will be showcasing the advancements with this technology over the past three years at Plast 2015 - May 5-9.
A full size 2X die garnered a lot of attention at NPE 2015, showcasing the mature evolution of the innovative 1X die that was first introduced at NPE 2012.
It is available in configurations of up to 20" diameter and from 25 to 200 layers, with an output in excess of 1000 lbs/hour.
With Blow-Up Ratios easily achievable in excess of 5 times, a 2X die is capable of lay-flats over 13 feet.
Alpha’s "Layer Sequence Repeater" Technology represents the next great leap forward in annular extrusion die technology for end-users and packaging producers seeking innovative new solutions to create higher performing and lower cost films and packaging.
It builds on the now well understood and proven principle that increasing the layer structure of plastic films creates great opportunities for improving their mechanical and barrier properties while also reducing input resin and other production costs.
The evolution from mono-layer to 3-layer co-extrusion films – and then on to 5, 7, 9, and 11 layer co-extrusion films – is proof of this.
Alpha Marathon takes this evolution a great step forward with its patented Alpha Layer Sequence Repeater Die Technology.
Our "LSR" Technology is based on an innovative new approach to die design and construction that creates film structures from 25 up to 200 discrete layers – creating never before seen film properties.
The secret is the ability to create and inter-weave layers that are less than a micron thick. These "Nano-Layers" have unique physical and mechanical characteristics that allow them to combine with other resins in new and important ways.
Qualitative/Quantitative Phenomena
Alpha's Layer Sequence Repeater Technology creates films that exceed the performance envelopes of current multi-layer films, including:
Alpha Layer Sequence Repeater also creates great opportunities to down-gauge current film applications to significantly reduce cost without sacrificing performance. When combined with Alpha's GlacierTM Water Quench technology, substantial production cost reductions can be generated, including:
Prime applications for Alpha's Nano-Layer and Glacier technologies include:
