What we solve

Precision

Thickness tolerance and clean edges affect test performance.

Material compatibility

Adhesives and carriers must be compatible with the assay and sterilization process.

Aging stability

Consistent performance over shelf life.

Traceability

Material and batch documentation for quality systems.

How a typical project runs

IVD mid-separator tape for a test-strip project

Challenge

A diagnostics manufacturer needed a mid-separator tape with stable thickness, clean die-cutting and compatibility with the assay.

Approach

We selected a medical-grade construction, produced a precision die-cut sample, and reviewed thickness and edge quality with the customer.

Outcome

The sample passed the customer’s evaluation and moved to pilot production.

FAQ

Do you supply medical-grade tape?

We supply medical assembly and IVD tape constructions. The available documentation depends on the grade; please share the application, sterilization method and regulatory requirement.

Can you die-cut IVD tape with tight thickness tolerance?

Yes. We review the carrier, adhesive and liner, and control thickness and edge quality during die-cutting. The achievable tolerance depends on the construction.

Can you provide samples for assay evaluation?

Yes. We supply samples for customer evaluation before production.

What an IVD assembly actually asks of a separator tape

Five properties get specified on almost every enquiry. They are not independent of each other, which is why a substitution is never a name swap.

Property	Why it matters in the device	How it gets checked	What it trades against
Thickness and tolerance	It helps set the fill volume and the flow path in the cassette	Measured on the construction as supplied, not on the adhesive alone	A thinner tape can change handling stiffness
Edge quality after the cut	Fibres and ragged edges seed bubbles and give a visual reject	Route chosen against the carrier, then examined under magnification	A cleaner edge can mean a slower or costlier cut
Assay compatibility	Adhesive and carrier can interfere with the reagent or the read	Compatibility testing on your reagent set, with the failure defined first	A compatible grade is often not the strongest bond
Aging over shelf life	The part has to behave at the end of the date as at the start	Aged samples under your storage condition rather than a fresh peel value	Aging stability narrows the candidate list quickly
Process exposure	Cleaning, curing or sterilization steps can move, discolor or deactivate an adhesive	The stated method and cycle applied to the actual construction	The grade that survives a process may not bond best

What to send with a medical enquiry

The device or consumable and where the tape sits in it, including whether it touches the sample path
The cleaning, curing or sterilization step the part goes through, named as a process rather than an acronym
The regulatory expectation you are working to, since that decides which documents have to exist
The dimensions and tolerances that matter, with the ones that only look important separated out
Volume and release pattern: a pilot batch and a monthly release are different conversations about the same part
The failure modes you have already seen, because they usually say more than the specification does

FAQ

Medical and IVD questions

Is this cleanroom converting?

No cleanroom classification is claimed on this page. What we do is documented handling, controlled die-cutting and material records for the part. If your project needs an environment class, name it at enquiry and we will state plainly whether the plant can offer it or whether the work belongs somewhere else.

Do you supply a biocompatibility dossier?

Not as a generic pack. Where a grade carries documentation from the material producer it is issued for that grade; a biological evaluation belongs to your device and your extractables protocol, not to a tape datasheet.

Can you hold a construction constant across batches?

That is what the incoming checks, the work-order record and the first-article file are for. A change in source material or tooling is treated as an approval event rather than a quiet adjustment.

Can a part be cut before the assay validation is finished?

Yes, and it is normal: prototypes are produced for evaluation by laser or CNC with no hard tooling made, and the production route is agreed once the design is stable. The report states which route produced the sample.

What is the smallest quantity you will document?

Documentation is prepared per order rather than per size, so a pilot batch can carry a first-article report. What is confirmed at quotation is the timing and the tooling that applies at that volume.
