A polymer pre-laid waterproof rolling material, comprising a polymer base material layer, a pressure-sensitive adhesive layer on the polymer base material layer, and a sand anti-sticking layer on the pressure-sensitive adhesive layer; the pressure-sensitive adhesive layer includes: 25-35 parts by mass of a styrene-isoprene-styrene block copolymer; 32-38 parts by mass of a C5 petroleum resin; 5-12 parts by mass of a 145 pentaerythritol modified rosin resin; 25-32 parts by mass of a naphthenic oil; 0.3 parts by mass of an antioxidant; and 0.5 parts by mass of a UV light stabilizer; the C5 petroleum resin has a softening point of 95-105° C. and a color number of less than 4; the naphthenic oil has a kinematic viscosity of 9-11 mm.sup.2 at 100° C. and a density of 0.8950 g/cm.sup.3-0.9100 g/cm.sup.3 at 20° C. The pressure-sensitive adhesive layer has a stronger bonding effect with sintered sand and further improves the bonding effect with concrete.

In the present invention, a solvent-based (SB) adhesive for the purpose of closing or sealing the open end of a bag, such as a plastic trash bag, liner or like, is coated to the exterior or interior surface of said bag and creates a neat, tight functional seal to said bag when twist activated.
