Tear Back Flash Banners are an alternative way to get the user's attention and provide the advertisement message in a more interesting way which enhances the browsing experience. Tear Back Flash Banners (also known as Peel Back Banners) consist of two Flash files. An initial Flash banner resides in the upper right corner of the web page. When the user clicks on the initial banner, it tears down the page to reveal the full content banner. There are no limitations for the size or content of both – initial and content banners. These banners can combine several banner techniques (video streaming, interactive content, order/purchase forms, etc.).
Adform strongly recommends to use „Adform Creative Toolkit“ extension for creating Tear Back banners. The manual of „Adform Creative Toolkit“ can be found here.
However, it's also possible to create Tear Back banners without Adform Toolkit. Below you will find instructions on this.

Instructions
1. There must be two banners – initial and content.
2. Content banner must have a close button, which executes the following JavaScript code:
a) In case you are using ActionScript 2:
import flash.external.ExternalInterface;
this.closeButton.onRelease = function():Void
{
try
{
ExternalInterface.call('ADFClose',_root.adId);
}
catch (e:Error)
{
}
};
b) In case you are using ActionScript 3:
import flash.external.ExternalInterface;
import flash.display.LoaderInfo;
ExternalInterface.call("ADFClose", LoaderInfo(this.root.loaderInfo).parameters.adId);
3. You need to implement the clickTAG variable. Detailed instructions for clickTAG implementation can be found here.
4. Banners should be compiled with Flash 8 or higher version. There might be pop-up blocker problems when interacting with lower version banners in Internet Explorer 7.
5. Test the Flash banner in live web environment using Adform Creative Test Module.
