What is Stretch Hood and how is it used? / Longhua
Stretch Hood is the more efficient and safe palletization technology
The Stretch Hood is an elastic tubular film which is used with special palletizing machines, without need of heat, unlike Shrink Film.
The Stretch Hood is produced with coextrusion technology, and it consists of 3 or more layers, ensuring higher holding properties without risk of puncturing or tearing due to heat-shrinking process.
HOW DO I USE THE STRETCH HOOD?
The Stretch tubular film is sealed on the top, stretched and placed on the product to be palletized. Since its perimeter is smaller than the perimeter of the product that I need to palletize, the film is stretched thanks to its elasticity and weared on the pallet. At the end of the process, the sealing bars cut the film to create a taylor made hood on the pallet.
This technology allows to use a smaller quantity of raw material and to reduce the weight of the packaging; at the same time the palletizing process allows energy savings and lower impact on the environment.
After packaging, the pallet will be more stable both during storage and transport.
STRETCH HOOD PROPERTIES
Stretch Hood is the perfect solution for unstable loads, and it is suitable for any kind of product and pallet size thanks to its properties:
- Holding force
- Tear resistance
- Puncture resistance
- Use wihout heat
The holding force and load stability are higher. This technology is an optimal solution thanks to its properties and technical characteristics.
PALLETIZATION STEPS WITH STRETCH HOOD
Here below the main steps of palletization with Stretch Hood are described:
1. The pallet is placed below the tubular film before the extension
2. The film is rolled on the extension arms
3. The top part of the tubular film is sealed to create the hood
4. The hood is stretched by the 4 arms
5. The hood is unrolled and weared on the pallet
6. The hood is released by the 4 arms and the pallet is ready
AREAS OF USE OF STRETCH HOOD
This technology is suitable for many different intensive-use sectors such as:
- Tiles and Bricks
- Building adhesives
- Topsoils and compost
- Wheat and cereals
