Starch-based film	Type of degradation	Degradation period	Surface morphology before and after degradation		References
			Description	Picture (left: before degradation; right: after degradation)
Starch/grafted polyurethane	Soil burial	180 days	Before: transparent and intact After: opaque and white		Tai et al. (2019)
Starch/LDPE/nanosilica	Soil burial	540 days	Before: transparent and intact After: surface had obvious traces of bacterial erosion		Datta, Samanta, and Halder (2019)
Starch/chitosan	Soil burial	90 days	Before: faint yellow and intact After: integrity of the composite film was obviously damaged after 90 days		Kochkina and Lukin (2020)
Starch/titanium dioxide nanoparticles	Soil burial	30 days	Before: intact After: surface had obvious traces of bacterial erosion		Amin, et al. (2019)
Starch/polyester/ cotton fibers	Soil burial	535 days	Before: good dispersion and interaction (b) After: starch was disappeared, fiber was damaged, the surface was rougher (d)		Moriana et al. (2010)
Starch/PVA	Soil burial	30 days	Before: very smooth (SP BD0) After: holes and cracks became larger and deeper (SP BD30)		Maiti, Ray, and Mitra (2012)
Thermoplastic starch/jute	Soil burial	60 days	Before: flat smooth surface (b)After: rough surface, with fibrous structure (g)		Behera et al. (2021)
Starch/PVA	Soil burial	60 days	Before: smooth surface structure, and had good combination (a) After: surface cracks and holes (b)		Ismail and Zaaba (2014a)
Starch/wood flour/microcrystalline cellulose	Soil burial	20 days	Before: smooth and even surface (left picture unlabeled) After: big holes and cracks (d)		Asgari et al. (2020)
