Guide
Void fill is the material that fills empty space inside sealed corrugated boxes to prevent product movement during transit. Getting this right is the difference between 1 percent and 10 percent damage rates.
This 2026 guide covers every main void fill option used in Indian packaging with real cost data and protection ratings.

The physics is simple: any product that can move inside a sealed box will impact the box wall during transit. A 500g product travelling 50mm inside a box before hitting the wall creates a measurable impact force. Over 500 to 1,500 kilometres of road freight, this impact happens thousands of times.
Void fill eliminates the travel distance. The product is immobile from the moment the box is sealed until the recipient opens it.

Protection level: High. 10 to 25mm EPE foam provides excellent cushioning.
Cost per shipment: Rs. 15 to Rs. 35 (foam sheet lining).
Sustainability: Not recyclable in standard streams.
Application speed: Moderate — cut and fit, or use pre-cut offcuts.
Best for: Electronics, industrial components, precision instruments. Any product where consistent, uniform cushioning is needed on all six faces.
Upackarts Foam Sheets and Rolls: upackarts.in/products/foam-sheets-rolls/
---
Protection level: Medium. Best for preventing movement, not absorbing heavy impacts.
Cost per shipment (at scale): Rs. 2 to Rs. 5 (at above 200 shipments/day).
Sustainability: LDPE plastic.
Application speed: Very fast (machine-inflated) — 60 per minute.
Best for: High-volume fulfillment centres above 100 shipments per day where per-unit cost and speed are the priorities.
Not for: Low-volume operations (machine investment not justified).
Upackarts Air Pillow Film Rolls: upackarts.in/products/air-pillow-film-rolls/
---
Protection level: Low. For products under 500g that need presentation, not protection.

Sustainability: 100% recyclable.
Best for: Gift boxes, hampers, jewellery presentation. D2C brands where unboxing experience is part of the product.

For fragile goods: bubble wrap or foam sheet. For non-fragile D2C products: kraft paper or honeycomb kraft paper. For high-volume operations: air pillows. The 2026 shift is toward paper-based materials driven by EU export requirements and D2C brand sustainability commitments.
Enough that the product cannot shift when you shake the sealed box. Practical test: seal the box and shake it firmly in all directions. If you hear or feel movement, add more void fill. The product should be completely immobile from all directions.
Correct void fill selection affects the box size choice — using the right box size (not oversized) is the biggest lever on dimensional weight. Honeycomb paper and kraft paper add less dimensional weight per unit of protection than foam sheet.
