FICHA TÉCNICA CINTA 3M TM 7847

(Color negro marcado en blanco)

 

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.
