The Need for Speed – and Precision
You know that splicing high-slip films – such as low-density polyethylene, or anything with a high degree of slip additive – at high speeds can be difficult, at best. The most common slip additives used to reduce film tackiness are organic waxes. They provide a lower friction coefficient on the substrates but migrate to the film’s surface and create a “boundary layer,” which reduces the wetting effect of the splicing tape – and can lead to web breaks during the splicing process.
The Old Way
Traditional solutions to splicing high-slip films – like liquid glues and additional tapes – are complicated and cumbersome. Liquid glues and extra tapes can limit your ability to splice at speed for applications such as bread bags or toilet paper wraps. This costs time and money.
A Trouble-free Solution from tesa
Now you can simplify splicing high-speed flexible packaging films – without sacrificing speed or efficiency. tesa® 51948 EasySplice FilmLine Black X is a new, very high-contact adhesive that provides excellent wetting properties on high-slip films. tesa® Black X combines speed and precision to change the game for high-slip films.
Collaborating with customers, we developed a flying splice tape with an integrated splicing strip. tesa® Black X was designed specifically for low-surface energy substrates like polyethylene films with a high amount of slip.
