Discover snack packaging engineering: nitrogen gas flushing, high moisture barrier against sogginess, puncture resistance, and center seal vs. stand-up bags.
Snack foods—such as potato chips, sev, bhujia, namkeen, and extruded puffs—are highly prone to moisture absorption (loss of crunch) and oil rancidity. They require multi-layer barrier packaging compatible with nitrogen gas flushing. Center seal pillow pouches offer high-speed filling for mass retail, while stand-up zipper pouches provide reclosable convenience for premium snacks.
| Snack Category | Recommended Format | Barrier Feature | Pactrum Recommendation | Weight |
|---|---|---|---|---|
| Potato Chips & Wafers | Center Seal Pillow Bag | Gas-flush nitrogen cushion | Center Seal (L072 / L079) | 50g – 150g |
| Traditional Namkeen (Sev, Bhujia) | Stand-Up Zipper Pouch | Resealable zipper for snacking | Stand-Up (L018 / L026) | 200g – 500g |
| Roasted Salted Cashews & Almonds | Stand-Up Zipper Pouch | Metallised oxygen barrier | Stand-Up (L010 / L018) | 100g – 250g |
| Bulk Snack Fryums | Center Seal Pillow Bag | Heavy S12-12-50 tensile grade | Center Seal (L077 / L081) | 500g – 1 kg bulk |
In snack packaging, moisture is the enemy of crunch and oxygen is the enemy of taste. Deep-fried savories and puffed grains require moisture transmission rates below 1.5 g/m²/day to maintain retail freshness throughout transit across India.
Standardized specifications relevant to Pouches for Snacks & Namkeen.
Nitrogen is an inert, harmless gas that replaces oxygen inside the pouch to stop oil rancidity, while inflating the pouch into a protective air pillow that stops chips from crushing during transit.
Yes, but transparent pouches should only be used if the snack has a rapid shelf turnaround (30-60 days) or uses low-oil extrusion, because light accelerates oil breakdown.
