Traditional cast stretch film is great for product load stabilization, but what if you are wrapping products that are still alive, like flowers and plants? Then, once the load is wrapped and stabilized, businesses can experience condensation which can affect the quality of the product. In order to enable business to still stabilize their load and keep up the production speed, Parkrite introduced Vented Stretch Film. "It is designed to help horticultural with load stabilization problems. It lets the product breathe", says Parkrite's Jim Carbone.

Condensation inside of the palatalized load can promote molding, and damage products. The two options for overcoming this problem is allowing products to slowly cool or warm up before wrapping or use a vented film to allow the products to breathe and reduce condensation, explains Carbone.
However, when choosing for option one - allowing products to cool or warm up slowly -, the production speeds decreases, which in turn increases companies’ expenses. Then, the second option probably becomes more attractive. "Vented stretch film offers great load stability while still allowing products to cool or warm-up. Vented stretch film offers comparable stretch to traditional gauged stretch film, why allowing breathing room."
The same condensation issue can arise when wrapping pallets of products that have moisture when curing. "Traditionally companies had to wait for the products to fully cure before palletizing the load. Traditional stretch film would hold the moisture in the load and not allow products to cure. With the die cut holes in vented stretch film, products can properly cure during transport. Other moisture issues often arise when dealing with any horticultural loads."
All in all, vented pallet wrap seems to help extend the life of foliage products during transport. At Pakrite, they offer vented stretch film in machine, hand stretch film with 3″ core, and hand stretch film with an extended core.
