Surely you have heard about air-egress vinyl films such as 3M Comply and Avery EZ Apply. RTape Corp. has developed AT75.1, an air-egress application tape. The embossed surface of the AT75.1 facestock impresses a grid pattern of air-egress micro-tunnels in the adhesive for bubble-free lamination of the application tape to vinyl graphics. The advantage is that when you laminate this application tape to a vinyl graphic, it is virtually impossible to entrap an air bubble underneath the tape. That’s important, because if you trap a bubble or wrinkle in the tape, it often results in a bubble in the applied graphic. This unique property has made AT75.1 a popular clear film application tape in the European market.
The deeply embossed surface also allows the user to tear AT75.1 by hand, in a straight line, for easy dispensing. In addition, the embossing contributes to the easy unwind of the film, which helps eliminate exhausting application tape struggles.
The slightly tackier AT75.1 adhesive system helps transfer problematic vinyl films and small lettering. Even though the AT75.1 adhesive is high tack, the tape is very easy to handle. If the adhesive side of the film accidentally folds onto itself, AT75.1 pulls apart easily without adhesive delamination! Following vinyl application, this unique adhesive releases easily from the applied graphics. This feature makes the tape ideal when installing wall graphics films, such as Oracal’s 631.
AT75.1 is also well-suited for making ready-to-apply (RTA) graphics. During storage, the application tape’s adhesive system will not build to vinyl graphics, nor will the adhesive yellow or discolor. Because of the film’s rigidity, AT75.1 exhibits excellent lay flat to exposed release liners and resists curling and tunneling.
