Rosenflex Stretch Hood films have a high degree of elasticity and memory retention allowing the film to be stretched over a load before snapping back tightly when released to give a high holding force on the pallet.
In comparison with shrink hood, the properties of our stretch film are designed and developed to offer better performance characteristics whilst allowing significant down-gauging opportunities to reduce cost. A 100mu based stretch hood film gives a better performance compared to a 140mu shrink hood for example.
As a result of our many years of experience, special raw material mixtures, and modern production technologies, our shrink-wrap films are extremely reliable and stable, and at the same time light and thin.
The three main characteristics that impact on the performance and suitability of the hood are tear strength, puncture force and holding force. Our Stretch Hood is a technical three layer co- extruded film which uses premium grade quality resins to meet the performance needs of the hooding operation giving easy seal with excellent stretch properties. Most shrink hoods are standard blends of LDPE (low density polyethylene) & LLDPE (linear low density polyethylene) and are more sensitive in the extrusion process; this means that they are prone to weak areas which only become apparent when shrunk.
However, with stretch hooding a thicker film does not necessarily mean a better performing hood; the product, packaging operation and logistics network all have an impact on the recipe, resin and dimension required. These factors all have to be considered carefully before the optimum proposal is made, but whatever that is our Super Stretch Hood is a true advancement.
A particularly non-slip surface allowing for reliable stability at high net weights.
The packaged goods can even be stored safely outdoors, because the films can be upgraded to withstand the effects of weather for up to three years
Thanks to their extreme resistance to tearing and puncturing, stretch hoods can reliably withstand sharp edges and even great net weights and are therefore suitable, for example, for the chemical or construction industry.
The mono material structure ensures stretch hooding is sustainable and recyclable.
