How long does an EVA insulin cooling case hold temperature?

In our in-house bench checks at 25 degrees Celsius ambient, a build with 6 to 8 mm closed-cell foam insulation and a 400 g pre-frozen gel pack holds 2 to 8 degrees Celsius for roughly 8 to 10 hours. Real-world time depends on pack size, ambient temperature and how often the case is opened, so we share the raw log with your team.

Are LIANPING medical cases made under ISO 13485?

The factory is certified to ISO 9001, not ISO 13485. For customers whose own quality system operates to ISO 13485 we supply documented incoming inspection, material lot traceability, CTI test reports and retained first articles, so the documentation fits into your device file without us claiming a certification we do not hold.

Can the case interior be wiped down with disinfectant?

Yes. PU leather grain and laminated Oxford cloth surfaces are specified to survive repeated wiping with 70 percent isopropyl alcohol without going tacky or lifting. Bare EVA is also wipeable but scuffs more visibly. Tell us your cleaning protocol at quotation stage and we will match the surface and seam layout to it.

LianPing Case launches innovative custom EVA medical cases to meet professional needs

Apr 6, 2024 2.9k views 2 min read

A home-care distributor in Lyon sent a brief that read like a packing puzzle: two insulin pens, a glucose meter, lancets, a sharps box and a gel pack, all in one case that has to hold a working day of temperature without being carried like a suitcase. The first sample kept the cold for six hours. The buyer needed ten. That gap changed the lining spec, the wall build and the closure, and it is a fair picture of how most medical case projects at our factory actually start.

Insulation is a build-up, not a material

Cold retention comes from layers, not from one clever foam. The working build is a 3 to 4 mm EVA shell, a 6 to 8 mm closed-cell PE foam insulation layer, and a reflective facing, with a pre-frozen gel pack sitting in its own pocket so condensation never touches the pens. In our in-house checks at 25 degrees Celsius ambient, a 400 g pack in that build holds 2 to 8 degrees Celsius for roughly 8 to 10 hours. Those are bench numbers from our workshop, not a certified figure, and we hand over the raw log so your regulatory team can read it. Storage cavities come from the actual pens and vials, because a loop cut 2 mm loose lets a vial rattle against the case wall for eight hours.

Cleaning and documentation

Clinical users wipe cases down between visits, so the surfaces get specified for that. PU leather grain and a laminated Oxford shell both survive repeated 70 percent isopropyl wipes without going tacky; bare EVA marks less but scuffs more. Seams are kept off the wipe path where the layout allows. Customers whose own quality system runs to ISO 13485 normally ask us for documented incoming inspection, lot traceability on sheet stock and a retained first article, all of which we issue under our ISO 9001 system. We do not claim ISO 13485 certification for the factory itself.

Insulin and injectables: insulated wall build, gel-pack pocket, elastic vial loops with a finger cut-out
First aid and response: high-visibility shell, internal elastic organisers, a clear sleeve for a contents checklist
Diagnostic kits: die-cut cavity for the meter or monitor, cable channel in the lid, moulded recess for a desiccant sachet

Materials are declared against RoHS and REACH with CTI test reports tied to the batch, and SGS factory audit records are available for review. Medical builds sit in the medical case range, minimum 500 pieces, samples in about three days for a simple layout. Send the device list and target temperature window to lucy@lianpingbag.com or start from the company profile if you need our audit file first. The Lyon sample is now at a 10-hour build with a second gel-pack pocket, and it goes back out on Tuesday.
