Stretch film is treated by passing a web of tackifier-containing, unbloomed thin polymer film through a heater so that the web is heated to a temperature sufficient to cause tackifier bloom prior to the web reaching a next stage in an in-line process. Also, a pattern can be applied to a thin polymer film. An oriented web of thin polymer film is passed across at least one heated roller having the pattern engraved thereon to define face regions and relief regions collectively conforming to the pattern. As the web contacts each roller surface, portions of the web positioned over the relief regions receive less heat than portions of the web positioned over the face regions, thereby causing the respective portions of the web to undergo differential, heat-induced shrinkage which imparts the pattern to the thin polymer film.

Transparent material processing with an ultrashort pulse laser

Номер: US20130095260A1
Принадлежит: IMRA America Inc

Methods for ultrashort pulse laser processing of optically transparent materials. A method for scribing transparent materials uses ultrashort laser pulses to create multiple scribe features with a single pass of the laser beam across the material, with at least one of the scribe features being formed below the surface of the material. Slightly modifying the ultrashort pulse laser processing conditions produces sub-surface marks. When properly arranged, these marks are clearly visible with side-illumination and not clearly visible without side-illumination. In addition, a method for welding transparent materials uses ultrashort laser pulses to create a bond through localized heating. The ultrashort pulse duration causes nonlinear absorption of the laser radiation, and the high repetition rate of the laser causes pulse-to-pulse accumulation of heat within the materials.

A method of producing curved, folded or reconfigurable structures includes providing a polymer film, exposing the polymer film to at least one of patterned radiation or patterned chemical contact, and conditioning the polymer film subsequent to the exposing. The polymer film includes a polymer that is active to cross-linking of polymer chains in response to the exposing. The exposing is performed such that at least one exposed region of the polymer film develops a gradient in an amount of cross-linking of polymer chains along a cross-sectional direction of the polymer film, and the conditioning of the polymer film removes uncross-linked polymer chains to provide a curved, folded or reconfigurable structure.
