Basically; slitting the film into (3) independent webs allowing the product to ventilate.
This is not a new concept, others have done this for years, but the price tag was always up over $5,000 for the option.
We are at $1,650 list price for this option on a semi automatic stretch wrapper. It is manually activated and can be set on or off to run like a regular wrapper. This helps reduce the cost of using netting and/or stretchable netting as they can use a regular stretch film.
