The most common model for "PP Case / Polypropylene Box Export" buyers is the WL1204 (120ร90ร40 mm OD, 100 g empty weight, PP body).
All PP Case / Polypropylene Box Export cases use engineering-grade polypropylene (PP) or PP+glass-fiber composite (PP+GF) for the shell, with CNC-cut closed-cell PE foam inside (density 25 kg/mยณ). The foam density is calibrated to absorb 1.2m drops on concrete while keeping your equipment from shifting.
The shell is rated IP65 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.5m). Temperature range is -30 ~ +90 ยฐC. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
Here are 3 real PP Case / Polypropylene Box Export foam layouts from 2024-2026: (A) Sony A7 IV + 24-70mm + 70-200mm + 3 filters + 2 batteries โ fits WL2808. (B) DJI Mavic 3 + RC + 4 batteries + charger โ fits WL2005. (C) RED Komodo + 2 lenses + monitor + cables โ fits WL5020. We share these at the 12h quote stage.
Top 5 mistakes we see in 2024: (1) Over-specifying size โ buying WL5020 when WL3812 fits. (2) Choosing by price alone. (3) Skipping IP certification. (4) Ignoring latch type. (5) Not requesting lot certificates. All five add up to a 2-3x higher TCO over 5 years.
For alternatives: soft padded bags (ยฅ50โ200, $7โ30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80โ300) are heavier, prone to denting, and 2โ4ร the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.
