Protein Bar Packaging That Maintains Freshness
Protein bars have specific shelf life requirements. The bars need protection from moisture, oxygen, and physical damage to maintain taste and nutritional value. Our custom protein bar boxes use barrier coatings and sturdy construction to keep bars fresh for 12-18 months. Pricing starts at $0.58 per box for standard sizes at 1,000+ quantity.
Box Configurations for Bar Products
Different bar sizes and counts require different box dimensions:
- Single bar box: 3x1x5 inches, long and thin for individual protein bars
- Box of 6 bars: 6x3x4 inches, most common retail configuration
- Box of 12 bars: 6x5x4 inches, standard shelf carton
- Box of 24 bars: 8x6x5 inches, bulk/gym size
- Variety pack: 8x8x3 inches, holds multiple flavors in single box
All boxes use 18pt SBS paperboard with interior barrier coating. Dimensions fit standard protein bar sizes (approximately 5 inches long, 2 inches wide, 0.75 inches thick).
Barrier Coating for Shelf Life
Protein bars require specific barrier properties to maintain freshness:

- Oxygen barrier: slows oxidation that causes stale taste, add $0.06 per box
- Fat barrier: prevents oil migration from protein bars into packaging, add $0.08 per box
- Foil laminate: maximum barrier for 18+ month shelf life, add $0.22 per box
Oxygen and fat barriers are recommended for bars with chocolate coatings or high fat content (over 5 grams per bar).
Bar Retention and Division
Keep bars organized and prevent damage during transport:
- No insert: bars loose in box, lowest cost, works for shelf display
- Paperboard dividers: scored partitions separate bars, $0.08 per insert
- Corrugated partition: stronger separation for shipping, $0.15 per insert
- Pillow pouch: each bar in individual wrapper inside box, $0.12 per bar
For e-commerce shipping, corrugated partitions prevent bars from shifting and breaking. Retail shelf display works fine with dividers or no insertion.
Window and Display Options
Windows allow customers to see bar count and verify flavors:
- Front panel window: 2x2 inch opening, shows bars without excessive light
- Full front window: maximum visibility, add $0.06 per box
- Perforated display: tear-off section reveals bars, add $0.08 per box
- No window: best barrier protection, $0.52/unit at 1,000 qty
Since protein bars typically have their own wrappers, light exposure through windows is less concerning than with unpackaged foods.
