Time required to seal PICS bags using the four different sealing methods.
| Sealing methods | Bag closing time (sec) (Mean ± SE) |
||
|---|---|---|---|
| 35 kg | 50 kg | Combined data | |
| TT | 76.91 ± 2.30 a | 72.50 ± 2.22 a | 75.15 ± 1.65 a |
| IR | 61.95 ± 1.70 b | 57.87 ± 1.64 b | 60.32 ± 1.23 b |
| FT | 51.55 ± 1.19 c | 46.78 ± 1.30 c | 49.73 ± 0.92 c |
| FS | 83.31 ± 2.31 a | 73.25 ± 2.20 a | 79.28 ± 1.73 a |
| ANOVA | F3,188 = 54.80, P < 0.01 | F3,124 = 45.54, P < 0.01 | F3,316 = 92.14, P < 0.01 |
Means within the same column followed by the same letter are not significantly different at P ≥ 0.05.
Sealing methods: TT = Conventional Twist-tied, IR = Inner liner rolled and outer fold-tied, FT: Both liners folded and tied together, FS: Both plastic liners folded and tied separately.
