Sträckfilm

Sträckfilm, also known as stretch wrap or shrink film, is a highly elastic plastic film primarily used for securing and protecting goods during storage and transit. It is typically made from polyethylene, though other polymers can be used. The key characteristic of sträckfilm is its ability to stretch significantly under tension without breaking and then return to near its original size, creating a tight, stable load.

The application process usually involves wrapping the film manually or using automated machines. As the film is stretched and applied, it exerts a holding force that binds items together, preventing them from shifting or falling apart. This is particularly useful for palletized goods, where multiple boxes or items are stacked and need to be consolidated into a single, manageable unit.

Sträckfilm offers several benefits, including load stability, protection against dust and moisture, and tamper evidence. It can also help reduce damage during handling and transportation by cushioning the contents. The transparency of most sträckfilm allows for easy identification of the packaged goods. Different types of sträckfilm exist, varying in thickness, stretchability, and cling properties, to suit different applications and load types. It is a widely adopted packaging material across various industries due to its effectiveness and cost-efficiency.
