Here’s How…
A 20” roll of manufactured pre-stretched stretch film costs about $31.35 per roll and gives you 5,000ft of surface area to work with, while 5,000ft of regular stretch film costs $64.00 per roll.
1 Pre-Stretched Roll 20” x 5,000’ =$31.35
1 Regular Roll 20” x 5,000’ = $64.00
Naturally, the $31.34 of previously pre-stretched film would appeal to most plant managers. However, when operating under the correct settings, there could be more to gain from stretching film using a stretch wrapper.
If you have a quality stretch wrapper that is operating at 200% stretch (80% of its ultimate-stretch**), the regular stretch film at $64.00 per roll could potentially give you 15,000 ft. as opposed to the manufactured pre-stretched film coming in at 5,000ft.
Pre-Stretched = 5000’/$31.35= $.00627 per foot
Can’t get stretched anymore
Regular = 5000’/ $64.00 = $.0128 per foot
Using a pre-stretch carriage on a wrapper, this film will stretch 3x as more at 200%
= Equiv. 15,000@200% = $.004267 per foot
5000ft. of regular film is really 15,000ft. when using a pre-stretch wrapper.
