[0125] FIG. 9a shows the top view of the film dispenser 150 made from paper or cardboard designed to be inserted into each side of a stretch film roll’s inner core. The film dispenser 150 has an outer surface 152 which the user holds when unrolling the film. There is a braking mechanism 154 that the user will squeeze to increase tension on the film as it is being unrolled.
[0126] FIG. 9b shows a side view of the film dispenser 150 made from paper or cardboard designed to be inserted into a stretch film roll’s inner core.

[0128] FIG. 9d shows a side view of two film dispensers 150 made from paper or cardboard each with an outer surface 152, each dispenser attached separately to each end of stretch film 162. The inner core of film dispenser 150 is approximately flush with both edges of the stretch film 162. The insert portion 156 (not shown) of a first film dispenser 150 slides into the end of core 160 on one end of the roll, and a second film dispenser 150 is installed into the opposite end 164 in the same manner.
[0129] In an embodiment, the film dispenser is made of a material with a high coefficient of friction compared to the extended core of the film wrap. When squeezed the film dispenser touches the extended core. This causes friction which, when increasing the amount of force applied to the extended core, slows down and stops the extended core from spinning and dispensing film. The low coefficient of friction between the film dispenser and the extended core allows the extended core to turn and release the film when the squeezing force is reduced and the outer mold no longer touches the core.
