But how do you know which FastPack box is right for your application? Let’s break down the differences so you can make an informed decision that protects your products and meets compliance requirements.
What is a FastPack Mil-Spec Box?
FastPack boxes are reusable, military-grade containers designed to meet PPP-B-1672C specifications. They feature rugged fiberboard construction, custom-cut foam inserts, and optional anti-static protection.
Benefits:
✅ Superior protection against impact, vibration, and environmental hazards
✅ Reusable for multiple shipments
✅ Compliant with key military and aerospace packaging standards
⭐ Star Packs (XA Series)
Overview
Star Packs, also known as XA Series boxes, feature integrated top and bottom foam cushioning and protective internal liners. They are ideal for small to medium-sized parts that require complete shock and vibration isolation.
Best for:
✔ Precision components (e.g., avionics modules, sensors)
✔ Medical instruments
✔ Small electronics
Advantages:
✅ All-in-one design for fast packing
✅ Excellent shock absorption
✅ Minimal setup required
➡️ Slide Packs (XC Series)
Overview
Slide Packs, or XC Series boxes, come with a sliding internal sleeve surrounded by foam cushioning. This creates a “floating” effect that isolates sensitive items from external forces.
Best for:
✔ Long, narrow components
✔ Circuit boards
✔ Instruments with delicate protrusions
Advantages:
✅ Provides extra protection for odd-shaped or elongated parts
✅ Easy to load and remove items
✅ Prevents shifting during transit
Telescoping Packs (XE Series)

Telescoping Packs, or XE Series boxes, consist of two halves that slide over each other to create a custom height. They are perfect for larger or taller components that don’t fit standard boxes.
Best for:
✔ Large or bulky items
✔ Multi-part assemblies
✔ Custom-height packaging needs
Advantages:
✅ Adjustable height for versatile applications
✅ Strong double-wall construction
✅ Cost-effective solution for oversized parts
