PP Case / Polypropylene Box is an engineered protective case in the protective case family: built by source factory kexinMaterials with IP67 sealing, impact-resistant PP copolymer or rotomolded PE shells and CNC-cut custom foam; wholesale, OEM and export supported.
A protective case is a transport and storage enclosure—typically engineered plastic or metal—for equipment, made by injection, rotational or blow molding, with impact resistance, sealing class and custom foam as the core buying criteria.
PP Case / Polypropylene Box: Product & Manufacturer Overview
For buyers, the true cost of a PP Case / Polypropylene Box 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.
The PP Case / Polypropylene Box is a key category in equipment protection. kexinMaterials, a source factory with injection, rotational and blow molding lines plus an in-house tool shop, serves this category from stock supply to custom tooling.

Standards & Industry Data
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).
IP Ratings (IEC 60529)
In IP67, the “6” means dust-tight (no dust ingress after a 2 kPa vacuum dust test) and the “7” means temporary immersion: the enclosure survives 30 minutes at 1 m depth with its highest point at least 150 mm below the surface, per IEC 60529 Clause 14.2.7.
Foam Inserts (EVA / PU / XLPE)
Three insert materials dominate: EVA (closed-cell, waterproof, firm support for precision instruments), PU foam (open-cell, soft cushioning, economical) and XLPE (chemically inert, non-shedding — preferred for medical and optics). CNC pockets are cut from the equipment's 3D data; drawing-to-first-sample typically takes 1–2 weeks.
Typical Applications
- Equipment and instrument transport
- Industrial storage and turnover
- Outdoor and specialty environments
- Private label and channel distribution
Product Overview
The kexinMaterials PP Case / Polypropylene Box is one-piece molded from engineering plastics, balancing impact strength, sealing and long-term durability — available from stock or fully customized. Key specs below.
On process: the PP Case / Polypropylene Box can be injection, rotational or blow molded. Injection gives precise sealing and repeatability; rotomolding yields large seamless shells with thick-wall toughness; blow molding suits light, economical builds. kexinMaterials runs all three lines and matches the process to your protection grade and budget.
For interior protection, the PP Case / Polypropylene Box ships with or accepts CNC-cut EVA/PE foam, routed to your equipment's 3D data so nothing shifts in transit; precision instruments can add ESD-safe or cushioned layered structures.
On quality, the PP Case / Polypropylene Box passes batch drop, stack and immersion checks; key models can be tested to MIL-STD-810H for drop and vibration, with material and third-party test reports supplied for export and industry acceptance.
Manufacturing Process
Process is matched to the category — injection for precision sealing, rotomolding for large tough builds, blow molding for lightweight economy — with in-house tooling and batch drop/seal inspection.
Field Case Studies
4,000 enclosure cases, PP/ABS selection, tooled to device dimensions with stable mass-production lead times.
6,000 generic protective cases under OEM brand with test reports and steady reorders.
