Title: Packing stretched film
Inventor: TOSHIMA KOZABURO
IPC: B32B27/00
Filed: 1991-12-12
Abstract: PURPOSE:To smoothly develop a film by improving the slippage of the film by allowing a surfactant to exude without lowering the self-adhesiveness of the film by compounding the surfactant with an adhesive layer of the film in a specific ratio (wt.%). CONSTITUTION:A packing stretched film consists of a non adhesive layer 11, a strength layer 12 and an adhesive layer 13 successively formed from the outside. In this case, 0.2-0.4wt.% of a surfactant is compounded with the adhesive layer 13. Herein, as the surfactant, for example, a liquid one is used and, when the compounding ratio thereof is below 0.2wt.%, desired effect is insuffucient and, when the compounding ratio exceeds 0.4wt.%, self-adhesiveness is lowered. The liquid surfactant is allowed to exude from the adhesive layer 13 without lowering the self-adhesiveness of the film to be utilized in the release of the film at the time of development. By this constitution, the slippage of the film is improved and the development thereof is made smooth and release noise is suppressed and antistatic effect is obtained.
