Eine praktische Übersicht der EVA-Koffertypen: Reißverschluss- und Rahmenverschlüsse, Schaum- oder Tabletteneinsätze, Shore-C-Härte von 40 bis 70 – und wie jeder Typ getragen wird.

Every enquiry reaching this desk starts with the same question: what goes inside? The answer decides which family a project falls into within the [full EVA case catalogue](https://evacasemanufacturer.com/de/products/category/eva-cases), and four decisions after that decide everything else: how it opens, what holds it, how hard the shell is, and how it gets carried.

## By closure

A clamshell zip running 270 degrees lets the case lie flat and open, which is what service technicians ask for when every part has to be visible at once. A three-sided zip with a fabric hinge costs less and keeps the lid captive, so it cannot be torn off by an overzealous courier. Magnetic flip lids suit small consumer goods opened one-handed on a shop shelf. Aluminium frame models with a key lock sit in another price class altogether, built for people who want the box to double as something you cannot quietly open.

- Zippers: #3 coil for light consumer cases, #5 for anything carried daily, reversed coil or metal when appearance outranks cost per unit.

## By interior

This is where two quotes for apparently identical cases diverge. Die-cut foam gives the tightest fit and the cleanest presentation, but every product revision needs new dies. Egg-crate foam in the lid over a plain base is cheaper and far more forgiving when the product shifts slightly between batches. Moulded velvet trays suit watches and jewellery. Elastic loops and a mesh pocket suit cables and chargers, anything whose shape varies week to week. Static-sensitive boards get antistatic foam specified to IEC 61340-5-1 rather than whatever coil happens to be on the shelf.

- Adjustable layouts using dividers, elastic loops and movable padded pockets suit repairs, sample kits and mixed loads, including most of the [tool case configurations](https://evacasemanufacturer.com/de/products/sub/eva-tool-case) we build.

## By hardness and how it is carried

Shell hardness on this line runs from Shore C 40, where a consumer case should yield slightly under the hand, up to Shore C 70 for a box expected to take a stack load or be sat on. Carry methods then multiply the options: wrist loop, detachable shoulder strap on 38 mm webbing, backpack straps, a pass-through sleeve that slides over a trolley handle, or integrated wheels and a telescoping handle like the ones fitted to our [rolling make-up trolley boxes](https://evacasemanufacturer.com/de/products/sub/makeup-trolley-box). None of those is a cosmetic choice, since each puts load into a different part of the shell and each needs reinforcement positioned before molding rather than retrofitted afterwards.

A buyer in Toronto sent a spreadsheet this week with twelve SKUs and one shared zipper specification, which is the tidy version of this whole process. The untidy version, three unverified CAD files and an evening of argument about draw depth, happens far more often and is usually settled by Monday.

## FAQ

**What are the main types of EVA cases?**

They sort four ways: by closure, covering clamshell zip, three-side zip with fabric hinge, magnetic flip lid and aluminium frame with lock; by interior, covering die-cut foam, egg-crate lid foam, moulded velvet tray and elastic loops; by hardness from Shore C 40 to 70; and by carry method from wrist loop through to wheels.

**Which insert works best for electronics?**

Static-sensitive boards and modules need antistatic foam specified to IEC 61340-5-1 rather than standard PE foam. For cables and chargers whose shapes vary between batches, elastic loops with a mesh pocket usually beat die-cut cavities, because a fixed cavity cut for one model will not fit the next one.

**What closure should I pick for daily field use?**

A clamshell zip opening 270 degrees lets the case lie flat so every part is visible at once, which is why service crews ask for it. Three-side zips with a fabric hinge cost slightly less and keep the lid captive. Flip-top magnet closures suit consumer goods opened one-handed on a shelf.
