mil

12.7 µm

Lightest

For short single-season crops on fine, well-prepared beds. The least material between sun and soil, so beds warm a touch faster, but it tears more easily on rough or windy sites.

The workhorse

most growers' pick

The balanced default for most field beds through a full growing season. Strength and cost meet in the middle, making it the safe pick when you're not sure which way to lean.

>720%

Elongation before break

ASTM D882, transverse direction. The film stretches with the bed instead of tearing (machine direction: >280%).

4-12 mo

Adjustable soil life

Order the breakdown window with the roll: rated to hold in the bed for 4, 8, or 12 months, then let go.

90%

Soil decomposition within a year

In soil at 20-30 °C and 60% humidity, the blend is 90% decomposed within one year of tilling in.

Biodegradable Mulch Film for Fields

Which mulch film thickness is right?būmigro biodegradable mulch film comes in three gauges — 0.5, 0.7, and 1.0 mil — drawn at the same scale. Match the gauge to your season length and how rough the bed is; thicker film resists wind, punctures, and end-of-season tearing.
