Manual (or Hand) Wrappers:
- Extended Core: An extension of the film’s core serves as a handle for wrapping; this type of wrapper offers little stretch control and is hard on hands.
- Mechanical Brake: A simple structure supports a film roll and a mechanical brake system provides resistance creating stretch of the film.
- Pole Wrappers: Similar to the Mechanical Brake system, but the roll and brake are at the end of an extended pole, creating an ergonomic design which eliminates the need to bend to wrap the bottoms of loads and strain to reach the tops of loads. Used for space missions too.
