FICHA TÉCNICA CINTA 3M TM
(Color gris plata
marcado en negro)
3M TM 7848 label
Stock is a specialty film stock that can be inscribed by a laser
beam - shich is designed to ablate the top layer off to create an
inverse image. Since the laser is also able to cut the entire label,
it provides high flexibility for producing just in time various
Densified Kraft (glassine)
- Modified Acrylate facestock for long-term durability and excellent
temperature, chemical resistance, excellent convertibility (kiss
- Markable with all Nd-Yag laser marking equipments available
on the market.
- Matte surface provides good printability resulting in 100 %
bar code readability.
- Two-layer construction and engraved inscription provide long
term readability, abrasion resistance and excellent image contrast.
- Brittle facestock material provides destructibility to meet
security labelling requirements.
- # 350 modified acrylic adhesive offers good adhesion on LSE/HSE
plastics with high initial tack.
- UL-approval: ongoig
- CSA-approval: on going
- Durable goods marking.
- Depending on the specific application alcso can be used for
tamper-indication. In most cases, labels cannot be transferred
without damage once they have been applied.

Adhesive Performance / Bond Strength
|Measured according to
DIN 30646, part 1 (jaw separation speed 300 mm/min, at 180º
angle, film width: 25.4 mm).
Since the facestock is destructible and can fracture during
adhesion testing, a support fil is laminated to the facestock
(onto side opposite adhesive) and adhesion testing completed.
Adhesive performance for the individual case can depend on the
texture of the substrate surface. The above adhesive values
are average values. They are not appropiate for specifications.
