Our production wrappers for shrink wrapping include one-step wrappers, fully automatic L-bar wrappers, L-bars with a shrink tunnel and semi-automatic L-bars. All are commonly used to cut and seal centerfold shrink film. The One-Step Wrappers with a built-in shrink hood and the L-Bar with the built-in shrink tunnel both are complete units that seal and shrink. The fully automatic and semi-automatic L-Bar Sealers will need a shrink tunnel to complete the system.
