Feature | Bidirectional Shrink Film | Unidirectional Shrink Film |
Shrink Direction | Even shrinkage in MD & TD | Shrink primarily in TD only |
Container Fit | Conforms perfectly to complex shapes (e.g., curves, angles) | May wrinkle or loosen on irregular surfaces |
Label Durability | Withstands washing/rinsing (ideal for reusable containers) | Prone to peeling or tearing under stress |
Print Quality | No distortion during shrinking; graphics stay aligned | Risk of image warping due to uneven shrinkage |
Versatility | Suitable for bottles, jars, and industrial parts | Limited to simple cylindrical shapes |
