What material are stretch sleeves made of?
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.
