DIOMASTER HPV MATT — Matt Polyester Inotec Label for Industrial Marking
DIOMASTER HPV MATT 4.156.04.01.00.35 is a robust multi-layer label material from Inotec based on polyester film with a permanent HPV adhesive. The material is designed for the production of durable barcode labels, inventory numbers, pallet labels, warehouse shelf labels, container labels and other identification solutions for industrial, warehouse and logistics applications.
Thanks to reverse printing, the barcode is protected by a transparent matt polyester film. This improves the label’s resistance to scratches, smearing, abrasion, mechanical stress, moisture and demanding operating conditions.

- container identification;
- returnable container marking;
- asset, equipment and material identification;
- warehouse, production and logistics accounting.
Application Recommendations
When processing DIOMASTER HPV MATT, the corresponding instruction sheet FB 362 — Processing Instructions for Barcode Labels should be followed. The surface must be clean, dry, stable and free from dust, grease, oil, release agents and other contaminants.
The ideal application temperature is approximately +20 °C. Application is not recommended if the surface temperature is below +10 °C. The labels reach their final bonding strength after approximately 72 hours at room temperature.
Adhesion
The table below shows peel strength test results on different surfaces. Values are given in N/20 mm. The test method is adapted from DIN EN 1939.
| Surface | After 20 minutes | After 24 hours |
|---|---|---|
| Glass | 42 | 45 |
| Steel 1.4301, polished | 44 | 46 |
| Polypropylene | 36 | 38 |
| Polyethylene | 30 | 32 |
Chemical Resistance
The tests were performed on labels affixed to a metal surface. After 24 hours, the samples were placed in a water bath at a temperature of approximately +21 °C.
| Liquid | 1 hour | 2 hours | 6 hours | 24 hours |
|---|---|---|---|---|
| Petroleum spirit | ok | - | - | - |
| Heptane | ok | - | - | - |

Testing in Liquids at Higher Temperatures
| Medium | Test conditions |
|---|---|
| Soap lye: 1.0% NaOH + 0.5% P3 Aquanta XTR | 70 °C, 40 minutes |
Attrition Resistance with Chemical Liquids
| Substance | Result | Conditions |
|---|---|---|
| MEK — methyl ethyl ketone | >500 abrasive movements | 10 N / 1 cm², over the entire length of the label |
| IPA — isopropanol | >500 abrasive movements | 10 N / 1 cm², over the entire length of the label |
Resistance to Washing
The wash test was performed on a polypropylene surface with direct positioning of the nozzle to the label.
| Parameter | Value |
|---|---|
| Water | 0 °dH |
| Pressure | 50 bar |
| Temperature | up to +80 °C |
| Nozzle movements | 150 movements over the label |
| Nozzle type | High pressure steam 40°, Kärcher 2.884-523 |
| Process speed | 80 mm/s |
| Distance between nozzle and test plate | 50 mm |
| Result | No visible separation of the label |
Resistance to Mechanical Wear
| Test | Conditions | Result / Method |
|---|---|---|
| Hardness measurement on protective surface layers | Testing on both PP and metal surface, 10 N | Erichsen Hardness Test Pencil Model 318 / van Laar testing geometry 0.5 mm |
| Attrition test on protective surface layers | Label affixed to a cardboard tube | >15,000 rotations, 14 rpm, 10 N / 4 mm² |
UV Resistance
The weathering test was performed for process black colour. Further colours are available upon request.
| Conditions | Result | Method |
|---|---|---|
| Label affixed to a glass surface | >1,000 hours | Adapted from ISO 4892-2, method A, cycle 2 |
Temperature Resistance
During the cold and heat test, the label was affixed to a polypropylene surface. According to the test result, the label did not detach from the surface.
| Test | Conditions | Result |
|---|---|---|
| Cold | -40 °C / 24 hours | The label does not detach from the surface |
| Heat | +100 °C / 24 hours | The label does not detach from the surface |
