DEGRADATION PROCESS
RONGHAO
06 / 09
Five Stages of Degradation
Cracking starts around day 90; fully degraded within 365 days
Induction stage
01Induction
About 90 days after laying, tiny pinholes appear on the surface — UV has begun the breakdown.
Cracking stage
02Cracking
Visible cracks form — water and air now pass through into the soil.
Fragmenting stage
03Rapid Breakdown
Strength drops sharply as microbes take over, driving rapid breakdown.
Breaking down stage
04Fragmentation
Breaks into small pieces that keep decomposing — no need to pick them up.
Fully gone stage
05Film-Free
Almost entirely gone within 365 days, breaking down into water, CO₂, and organic matter that return to the soil.
ADVANTAGE
No collection, no recycling
— saves labor every season
Till it under after breakdown, with no extra steps
