HOW TO WORK OUT SHRINK WRAP FILM SIZES
Measuring for shrink film is fairly simple, but is relevant to the type machine you intend on using. i.e CFS for L sealers, side sealers and Chamber machines. Sleeve Sealers use SWS as do mailing machines. See below for measurement formulas for each type of film. Remember if the exact size needed is not available go to the next size up. All of our shrink film has a shrink rate of at least 30%. Centerfold Shrink Film Measurement Formula:- So for a product say a board game 100mm wide x 50mm high, Centerfold Film Width Needed= product Width + product Depth x 2 x 1.1/2 = 350, meaning you would need 350/700 film
Single wound sheet measurement formula:- So for a product say a tray of beer 200mm wide x 100mm high, single wound film needed=product width +1.1/2 product height= 350mm.
