ASPC MFI3820

1 product description

MFI3820 is a medium density polyethylene, which has a broad molecular weight distribution and high melt strength. This product specially designed for producing thin films with high tear resistance, good sealability, high strength and high draw down.

2 applications

MFI3820 is recommended for blown film extrusion. This product is suitable for manufacture of high strength carrier bags and high quality thin films for uni/multi-wall packaging.

3 processing

Extruder temperature profile: 180-250°C

Frost line height: 6-8 times die diameter.

Blow Up Ratio: 3-5

Recommended film thickness: 10 to 50 μm.

Please note that, these processing conditions are recommended by producer (for 100% MFI3820 resin, not in the case of blending with any other compatible material) , but because of the many particular factors which are outside our knowledge and control, and may affect the use of product, no warranty is given.
