Methods and devices for forming a vertically-oriented multilayer laminates, for example, a vertically-oriented multilayer laminates, are provided. The laminates may be fabricated by hardenable fluids, for example, polymers that are directed along flow paths to divide, repossession, and combine streams to provide the desired laminated structure. The flow divisions and recombination may be practiced repeatedly wherein laminates have tens or even tens of thousands of individual layers may be produced. The polymers used may have comparable viscosities, for example, having viscosity ratios of less than 3. Though aspects of the invention may be used packaging, aspects of the invention may be applied to any field where laminated structures are desired.
