PureNil™ 0 Water-Soluble Pouch Stock
Plastic-Free Stand-Up Pouches for Printable, Flexible Packaging
The world’s first 100% bio-based, plastic-free packaging substrate. PureNil™0 creates compostable stand up pouches and heat seal pouches that completely disperse in water in under 7 seconds. PureNil 0 does not contain PVOH, PVA or microplastics. Direct food contact capable for confectionery, snacks, and single-use food packaging applications requiring certified plastic free packaging.
How PureNil™ 0 Water-Soluble Pouch Stock Works
SmartSolve PureNil™0 combines FSC-certified wood pulp fibers with a proprietary 100% bio-based heat-sealable coating. Unlike traditional plastic films or PVOH-based materials, every component of PureNil™0 is derived from renewable materials with zero plastic content.
The outer paper layer provides structural integrity and printability during manufacturing and use, while the bio-based heat-seal layer creates secure, hermetic seals on form-fill-seal equipment. When the pouch contacts water, both layers disperse completely in 6-7 seconds with minimal agitation, leaving zero microplastics behind.
PureNil™0 is our first direct food contact capable material for lower barrier requirements, making it ideal for snack packaging, confectionery wraps, powdered drink mixes, and single-use food applications.
SmartSolve PureNil™0 is compatible with existing form-fill-seal equipment, making the switch from plastic pouches seamless. The material accepts flexographic and digital printing with water-based inks,[1] delivering professional print quality while maintaining complete biodegradability.
