Abstract: An adhesively sealed product is disclosed comprising a first surface, a second surface, and an adhesive layer bonding said first surface to said second surface; said adhesive layer comprising a copolymer and a protective colloid, the copolymer being derived from monomers including one or more a C1 to C20 alkyl(meth)acrylates and having a glass transition temperature (Tg) of from −40° C. to 0° C. using differential scanning calorimetry (DSC), wherein opening the product by separating the first surface from the second surface results in adhesive failure of the adhesive layer thereby resulting in a reclosure adhesion of less than 0.5 N/15 mm. A method of producing an adhesively sealed product is also disclosed.
