Attachment system

Abstract

A dispenser includes an upper member having a slot and a lower member attached to the upper member thereby forming a housing, the lower member having an outer surface; a stack of sheets assembled in a fan-fold configuration disposed in the housing; and a polymeric holding film having a first surface attached to the outer surface of the lower member. The holding film having a flexural modulus less than about 50 MPa, as measured according to ASTMD790 standard, and a roughness parameter, R a of less than about 1 micrometer, as calculated according to ASME B46.1 standard.

1 . An attachment system comprising:
 a polymeric holding film having a first major surface and having a flexural modulus of less than about 50 MPa, as measured according to ASTM D790 standard and a roughness parameter, R a , of less than about 1 micrometer, as calculated according to ASME B46.1 standard; and   an attachment mechanism disposed on the first major surface of said holding film.   
     
     
         2 . The attachment system of  claim 1 , wherein the attachment mechanism is selected from the group consisting of adhesive means, mechanical means, and a combination thereof. 
     
     
         3 . The attachment system of  claim 1 , wherein the adhesive means is selected from a group consisting of stretch release adhesive, double-sided pressure sensitive adhesive tape, and cyanoacrylate adhesive. 
     
     
         4 . The attachment system of  claim 1 , wherein the holding film has a first surface area and the attachment mechanism has a second surface area, wherein the ratio between the first surface area to the second surface area is from about 10:1 to 3:1. 
     
     
         5 . The attachment system of  claim 1 , wherein the holding film has a nominal thickness from about 0.01 to 0.1 inch. 
     
     
         6 . The attachment system of  claim 1 , wherein the holding film is polyurethane or a polymer derived from ethylene-propylene diene monomer. 
     
     
         7 . The attachment system of  claim 1  disposed on a base of an article. 
     
     
         8 . The attachment system of  claim 1 , wherein the attachment mechanism is disposed centrally on the holding film. 
     
     
         9 . The attachment system of  claim 1 , wherein the holding film has a flexural modulus of less than about 10 MPa. 
     
     
         10 . The attachment system of  claim 1 , wherein the holding film has a flexural modulus from about 5 to 7 MPa.
