PROCESSED MATERIALS:

LDPE, HDPE, LLDPE, mLLDPE


ADVANTAGES:

Three-layer films “ABA-type” produced on Aleko blown film machines features a range of advantages comparing to monolayer films:

Reduction of production costs by introduction into the middle layer (B) up to 100% of the recycled material or up to 70% of CaCo3 additives.

  • Layers ratio up to 1/8/1;

  • Excellent resalable condition as the outer layers (A) are made of the raw material and cover the middle layer.

  • Improved mechanical properties beside mono-layer analogs (increased mechanical properties of 3 layer film in comparison with a single layer film made from the same material)

In the design of three layer blown film machines by Aleko, we used a modular type for assembly which makes it easy to configure the machine for specific client needs. All series of extruders Aleko are completed with high-performance screws, which have been designed under license of company Plamex (Germany). Screws have a complex geometric shape which allows to achieve high performance and efficiency of mixing
