Salt Packaging: Preventing Caking and Chemical Degradation with Multi-Layer Films

Multi-layer laminated packaging pouch for salt and highly hygroscopic FMCG powders

Salt is one of the most chemically aggressive and hygroscopic products in the FMCG sector. If packaged in substandard, highly permeable plastics, it will aggressively pull moisture from the surrounding air. This rapid moisture ingress leads directly to “caking”—where the free-flowing grains fuse into solid, unusable blocks before ever reaching the consumer’s pantry.

1. The Threat of Moisture and Corrosion

Standard LDPE (Low-Density Polyethylene) bags offer minimal defense against ambient humidity. When salt absorbs moisture, the resulting brine can also cause severe degradation to the packaging seals and print layers if they are not chemically resistant. To ensure a long shelf life, salt packaging requires an absolute barrier against both Water Vapor Transmission (WVTR) and chemical corrosion.

Multi-layer laminated packaging ensures zero moisture ingress, keeping salt free-flowing and preventing caking.

2. Multi-Layer Lamination for Extreme Protection

To combat these issues, premium salt manufacturers upgrade to heavy-duty multi-layer lamination. By bonding a high-tensile outer layer (like BOPP or PET) to a thick, specialized PE sealant layer, the pouch achieves hermetic seals that completely lock out atmospheric moisture.

  • Chemical Resistance: Specialized inner films prevent the highly alkaline salt from breaking down the heat seals during long-term warehouse storage.
  • Puncture Resistance: Salt crystals are highly abrasive. Multi-layer structures prevent the internal product from causing micro-punctures in the film during transit.
