<p>A coal emulsion driveway sealer is packaged in a sealed bag (12). The volume of sealer is less than half the capacity of the bag and the bag is substantially completely evacuated but for the sealer (20). The separated sealer is mixed by compressing the sides of the bag to induce turbulent flow of the paste and liquid for hydraulic mixing thereof. The sealer may be dispensed at a controlled rate without spattering by cutting a corner (18") from the bag to provide a pour spout. The bag with the sealer may be contained in a carton (28). The bag membrane comprises an aluminum layer (52) vapor deposited on polyester (50). Those two layers are sandwiched between layers (54, 56) of EVA copolymer. </p> |
