Is Puffing Up Snack Food Bags Just for Looks?
📦 Is the air just there to reduce the amount of product or cut costs?
❌ NO, NO, NO!
There’s real science behind this! 💡
🔬 The Science Behind Inflated Food Packaging
Almost all food spoilage is directly or indirectly related to oxygen.
✅ Core Solution: Isolate food from oxygen to extend shelf life
✅ How It’s Done: Fill the bag with an inert gas to displace air
⚗️ Why Nitrogen?
Nitrogen is the #1 choice for food packaging inflation. Here’s why:
🛡️ Inert Protection: Non-oxidizing, inhibits oxidation and microbial growth
💧 Moisture Barrier: Positive pressure keeps moisture out, slowing spoilage
📦 Physical Cushion: Gas buffer protects fragile snacks like chips from breakage
💰 Best Value: Inexpensive, non-toxic, odorless, and highly stable
📝 Regulatory Note:
Nitrogen is approved as a processing aid in food manufacturing
(no labeling required and no residual limits)
⚠️ Must meet national food additive safety standards
Note: CO₂ is also commonly used for food preservation
🥔 The Truth About Inflated Chip Bags
🔍 Main Purposes of Inflation:
▸ Anti-oxidation (Keeps chips crisp!)
▸ Moisture resistance
▸ Crush prevention
⚙️ Packaging Process Workflow:
Feeder → Multi-head Weigher → Vertical Form Fill Seal Machine → Nitrogen Generator
✨ Key Step: The forming tube is equipped with a gas filling device, which is connected to the nitrogen generator for precise nitrogen infusion.
