Multiple challenges are present in the field of load unitization: on one hand the increasing request to reduce the amount of packaging and on the other hand improved load securing during manipulation and transport remains highly important. This is reflected in new and stricter European guidelines on packaging and waste reduction and on load securing. Total Petrochemicals offers polymer resins adapted to different types of load unitization that can tackle these challenges.
Stretch hood is the end-of-line packaging solution with the highest growth rate and where the packer can combine down-gauging and higher stretching to reduce packaging weight while maintaining the load securing: tamper proof, water proof and vertical tension on the pallet.
