Stretch sleeves are essentially a low density polyethylene (LDPE). Certain additives can be combined will the LDPE to enhance specific properties.
The base material is clear. Reverse printing is commonly used with clear film to protect the ink from surface scuffing and scratching. Many applications require a high opaque white film which is then surface printed. This surface print can be protected with a varnish.
CCL Auto-Sleeve also metalizes the LDPE for a very unique silver finish. The combination of this film and flexographic inks combine for some unique looks.
Triple-S is a very new material developed by CCL Auto-Sleeve to provide a more cost effective alternative to sleeve contoured bottles. Before Triple-S, contoured bottles required the use of shrink sleeves which are more expensive than stretch sleeves. This new material will allow for the sleeveing of contoured bottles without the need for the application of heat (shrink tunnel).
CI Flexographic printing is what CCL Auto-Sleeve utilizes for stretch sleeve applications. We have been printing on LDPE film for over 30 years and this technology lends itself well to this very elastic material.
There are several excellent brands of application machines available in the market today. The choice is usually based upon your required line speed. CCL Auto-Sleeve has a line of our own refurbished machines capable of sleeving up to 90 bottles per minute. We can certainly work within your sleeving requirements to recommend the right equipment for each application.
