Mini Floating Dry Case: confirm internal dimensions first (equipment size plus foam allowance), then protection rating (IP67 is the benchmark) and shell material (PP for value, ABS for surface hardness, rotomolded PE for large sizes). Custom sizes available via tooling.
A waterproof case uses a silicone gasket and latches to achieve IP67 dust-tight and watertight protection, suited to marine, outdoor and rescue use where gear must stay dry after brief immersion.
Mini Floating Dry Case: Product & Manufacturer Overview
Outdoor work demands waterproofing, crush resistance and buoyancy margin in one shell. kexinMaterials cases offer positive buoyancy references under rated loads, lockable latches and shoulder systems for on-water operations and island logistics.
For buyers, the true cost of a Mini Floating Dry Case is more than unit price: carton specs shape freight, and spare parts and replenishment shape long-term use. kexinMaterials optimizes container loading and ships wear-part kits with volume orders to lower your total cost of ownership.

How kexinMaterials Compares
| Dimension | kexinMaterials | Generic market cases |
|---|---|---|
| Rating | IP67 standard, IP68/IPX6 optional | Splash-only, floods when immersed |
| Sealing | Silicone gasket + auto pressure-equalization valve | No valve, collapses at altitude |
| Weathering | UV-stable modified PP, salt-fog resistant | Generic resin yellows outdoors |
| Latches | Waterproof latches with rubber gasket | Plain clasps leak |
| MOQ | From 50 pcs, custom colors | High batch barrier |
| Proven use | Marine/diving/fishing field cases | Lacks scenario proof |
Waterproofing: rated IP67 — fully dust-tight and leak-free after 30 minutes at 1 m depth. Sealing relies on a continuous silicone gasket in a molded rim channel, plus an automatic pressure valve so the case opens normally after rapid pressure changes.
Portability: compact models are weight-optimized without sacrificing structure — one-hand carry, with strap and belt-mount options for personal and field use.
Standards & Industry Data
IP68 vs IP67 (IEC 60529)
IP68 covers continuous immersion. IEC 60529 does not fix a universal depth or duration — the manufacturer declares conditions that must exceed IP67 (typically 2–10 m). Always request the test certificate to confirm the actual depth/duration rather than relying on the “IP68” label alone.
Shell Materials Compared (PP / ABS / PE)
Industry data puts PP (polypropylene) at ~55% of plastic protective-case share — strong chemical resistance, low-temperature toughness and cost efficiency; ABS holds ~30% with harder, glossier surfaces; large thick-wall cases favor rotomolded PE. Plastic/polymer cases together account for 63.7% of the industrial protective case market (2025).
Water-Jet Tests (IPX5/IPX6)
IPX5 uses a 6.3 mm nozzle at 12.5 L/min from 3 m for at least 3 minutes (~30 kPa); IPX6 steps up to a 12.5 mm nozzle at 100 L/min (~100 kPa), simulating sea waves and pressure washing. Marine and outdoor cases should meet at least IPX6.
Typical Applications
- Overlanding and expedition gear storage
- Marine fishing and boat equipment
- Photography gear in the field
- Emergency-response equipment staging
- Water sports and dive gear transport
- Utility line-inspection tool carry
Sizing & Selection Guide
To size a Mini Floating Dry Case, measure the largest 3D dimensions of the payload and allow 30–50 mm per side for foam, then match against internal case dimensions. Above 30 kg payloads, add wheels and reinforced bases.
kexinMaterials stocks a full size run from personal cases to large transit trunks with published internal dimensions; if nothing fits, we evaluate mold revisions or new tooling — selection advice is free.
Manufacturing Process
The whole range is high-pressure injection molded with gasket-channel tolerances held to the 0.1 mm class. Each batch is sample-tested with a 1-meter, 30-minute immersion to keep IP67 performance consistent.
Field Case Studies
2,000 marine equipment cases, IP68 + UV-stable, no aging or leakage after 18 months in salt spray.
900 dive-gear cases with pressure-equalization valves, no collapse during high-altitude transit.
