ExxonMobil Signature Polymers has collaborated with Inplac to develop stronger heavy duty sacks without increasing film thickness, especially for 50kg bags used in demanding markets like agriculture and construction.
The companies aimed to improve the bags’ performance while maintaining easy processing, strength, and stability. To achieve this, ExxonMobil Signature Polymers developed a new film formulation using Exceed Stiff+ m 0926 resin.
ExxonMobil says this material improved tear and puncture resistance while maintaining processability and film stiffness, and enhanced sack durability and load stability, providing better protection during handling. The formulation apparently simplified production by meeting multiple market needs with a single film structure, boosting manufacturing efficiency and expanding business opportunities.
The new sack film is 102.5-microns, with ‘superior’ machine direction tear strength and enhanced creep performance compared to the incumbent solution. During testing, the sacks are said to have survived 10 drops from 3 meters and a 9-meter drop test without failure.
In related news, ExxonMobil teamed up with Malpack in April to launch a high-performance pre-stretch film using ExxonMobil’s Signature Polymers, said to have high tenacity, holding force and stability while maintaining production efficiency. Key performance features of the new film include high downgauging potential, reportedly enabling thinner film designs that maintain performance while using less material, contributing to cost savings.
More recently, finishing solutions supplier Nobelus released a line of premium wet films for flexible packaging with no adhesive layer, said to be compatible with solventless and solvent-based adhesives applied on flexographic presses or wet laminating systems. The new range includes sandpaper-textured FineGrit Film and the scratch-resistant ScuffProof Film, designed for damage resistance, said to have high durability to protect ink and ensure the finish does not rub off with regular use.
