Series 3420

Polymeric Overlaminate

Series 3420 is constructed of a 75 microns polymeric vinyl film with clear, permanent pressure-sensitive adhesive. Designed to protect and prolong the life of printed images, Series 3420 is made of a polymeric facestock and available in gloss, satin and matte finishes.

Series 3420 is rated for outdoor durability up to 5 years. 

Applications & Features

  • Protective overlaminate for all promotional, intermediate and industrial, calendered products
  • Short-term signage, kiosks and POP displays
  • UV inhibitors to protect and extend the life of your printed graphic
  • Arlon overlaminate film is designed to be laminated cold without any heat
  • Series 3420 Gloss and Matte are approved EN 14041 for slip resistance for interior floor graphics

Actual weathering durability depends on surface preparation, surface maintenance and exposure conditions. Successful weather resistance is characterized by the retention of legibility.

Series 3420 will resist weathering best when applied to vertical or upper outboard angles. Horizontal angles, such as hood and auto roof surfaces, will deteriorate more quickly than vertical. This is due to increased exposure to sun and moisture, as well as continued high deposition of dirt and atmospheric contaminants. Arlon does not recommend its film for horizontal or close horizontal applications.


Series 3420 Gloss and Matte are approved under the European Standard Certification EN 14041 for slip-resistance as a floor graphic material for indoor dry conditions. Arlon recommends DPF 8000™ Ultra Tack, DPF 8200 High Tack and DPF 4600GLX/MLX as the compatible media. These product combinations are recommended for short term interior floor applications, for an expected life of up to 6 months. To determine the best product for the application Arlon always recommends testing on the surface before using the above products. Product performance can vary greatly depending on the surface type, level of foot traffic, elemental exposure, the carpet type, and floor condition. Due to these variables, Arlon only warrants the material(s) for standard manufacturers defect and is unable to offer a warranty for the performance or clean removability of these products for floor graphic applications. 
Due to these variables, Arlon is unable to offer a warranty for the performance, expected life, or clean removability of these products for floor graphic applications.
