Recently we received an inquiry from a customer in Egypt: PVC electrical insulation tape, 0.13 mm × 18 mm × 20 yd - tack retained after four re-applications, self-extinguishing when the flame is removed, individually sealed, 200 rolls per carton.
The customer wrote five lines. LIANTU treated them as a specification, not a wish list. The buyer's two field tests were blunt: stick it to a not-particularly-clean tabletop, peel it up, and repeat four times - does it still hold? Hold a lighter to it and take the flame away - does it put itself out? The answer to both is yes.
Thin film is harder to make than thick film: at 0.13 mm it has to hold tensile strength, conformability and dielectric margin all at once. LIANTU controls the film on its own raw-material production line, so thickness consistency is managed at the source rather than renegotiated with an outside supplier on every lot.
On adhesion
Passing a peel test on clean steel is not difficult. What the customer tested was a dirty tabletop - dusty, slightly oily - applied, peeled up and repeated four times, with tack still there on the fourth cycle.
That test is harder than it looks, because it stresses three failure modes at once:
- Contamination. Adhesive that bonds instantly to a clean plate fails outright on dust - it grips the dust, not the substrate.
- Adhesive transfer. A soft adhesive leaves a layer behind on every peel. By the third or fourth cycle, there is not enough adhesive left on the roll.
- Anchorage. Adhesive that shears off the backing leaves nothing but residue and a tape that no longer sticks to anything.
LIANTU formulates for the fourth application, not the first. Four glue-coating machines apply the adhesive, with coat weight and primer anchorage held inside a narrow window - the step that decides whether a roll performs on the bench in your workshop or only in a brochure.
On flame retardancy
LIANTU builds the flame-retardant system into the PVC while keeping initial tack and flexibility intact - a genuine balancing act, because flame retardants are fillers by nature: add them and the film stiffens, tack dulls, and calendering at 0.13 mm gets harder. Locking both properties into a single 0.13 mm film is the technical core of this product, and the reason both tests have to run in the same lot release.
For markets that require documented evidence, LIANTU arranges test reports against the standard actually enforced locally, and issues RoHS and REACH declarations, confirmed order by order.
Packaging
LIANTU's sequence has four layers: each individual roll sealed → 10 sealed rolls loaded into one tube → the tube sealed again → 200 rolls per carton.
Every layer earns its place: double sealing keeps out moisture and dust and survives a sea-freight cycle and a monsoon season. Every layer also carries print: the core or the roll wrap, the tube label, the carton shipping mark. On private-label runs, artwork, barcode and country-of-origin marking are all applied at this stage.
