# PE-Based Powder Sacks ExxonMobil and Scientex Swap Paper for a Vented PE Format By Adam Harrie | Written with AI assistance | Published 2026-10-07 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/pe-based-powder-sacks References: [packagingstrategies](https://www.packagingstrategies.com/articles/106713-exxonmobil-and-partners-collaborate-on-pe-based-heavy-duty-sack-solution)  ExxonMobil, working with Scientex, developed a polyethylene heavy-duty sack that helps keep fine powders dry during packing and transport. The bag uses a form-fill-seal (FFS) format for automated filling lines, offering moisture-sensitive products an alternative to paper sacks that can absorb humidity and require plastic liners. 'Exceed Tough+' performance resins provide the stiffness and toughness needed for bag drops, while Scientex's 'VentiFlex' design releases trapped air after filling without exposing the contents. Compared with a paper reference sack, the PE bag can weigh up to 13% less. For brands, this means a simpler path from multi-layer paper sacks to a mono-material PE format designed for recyclability. It also links material choice to a 6% packaging cost reduction at a 10 million-bag scale, making the switch easier to justify.
