Product Description
3M TM 7848 label
Stock is a specialty film stock that can be inscribed and converted
by a laser beam - which is designed to burn the top layer off to
create an inverse image. Since the laser is able to bur/cut the
entire label, it provides high flexibility for producing various
formats.

Features
- Cast modified Acrylate facestock for long-term durability and
excellent temperature, chemical and environmental resistance,
excellent convertibility (kiss cutting).
- 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
of images.
- Brittle facestock material provides destructibility to meet
security labelling requirements.
- # 350 modified acrylic adhesive offers good adhesion on LSE
plastics with high initial tack.
- No corrosive emissions during the laser marking on process.
Application
- Durable goods marking.
- Depending on the specific application also can be used for tamper-indication.
In most cases, labels cannot be transferred without damage once
they have been applied to a surface.
