Stretch Hood
The product (stretch hood) is developed for the automatic packaging, of any kind and weight loads, like industrial sacks, building materials, sanitary items etc, on specialized palletizing equipment. The stretch hood is in the form of rolls with parer core internal dia. 76 mm and 152 mm. The palletizing unit welds the roll bottom, stretches it uni - formly by height, and applies it around the packaged product. By releasing the film, it is firmly tightened on the packaged product.
The advantage of the stretch hood film, compared to the conventional stretch film and heat shrinkable Pallet Hood is the uniformity of the tightening force by height, the lack of the cling layer, the tightening in the absence of heat and of course the strong tightening force.
The stretch hood film is manufactured in 3-Coex Lines, with special category Polyethylenes, thus ensuring the necessary properties and the trouble free operation of the Paletizing Line.
Among the particular characteristics of the stretch hood film are:
- UV protection (if requested), 140 Kly (one year at Greek climate).
- High mechanical properties for the tightening of heavy loads under hard conditions.
- Excellent thickness profile.
Typical roll dimensions:195- 105 cm .Thickness 120 My
