What that means in practice

A bimodal HDPE film resin, and the one grade here whose datasheet is quoted to ASTM rather than ISO methods. The units match the pipe compounds above but the test does not, so the figures are not directly comparable with them.

If these numbers are not something you work with daily, our HDPE grades and pricing guide explains what they measure and how prime, off-spec, regrind and regranulate differ.

What to check before buying Borstar FB5600

• Melt flow rate and density together decide how it runs and what the film does — but check which method the figures are quoted to. Borouge quote some film grades to ASTM and their pipe compounds to ISO, and the two are not interchangeable.
• Ask whether it is a straight linear or a bimodal terpolymer. The Anteo grades are terpolymers and the sealing performance is what you are paying the premium for.
• Gels and optical defects are the usual complaint with traded film resin. If the end use is transparent film, ask for the gel count on the actual lot rather than the datasheet.
• Confirm the additive package. Slip and antiblock content changes how the film handles on the line and it is not always visible in the grade name.
