Abstract
Semicrystalline polymers are heat-sealed with metals under pressure and at a temperature between the glass transition temperature and the softening temperature of the polymer by prior exposure of the polymer surface to UV radiation produced by the decomposition of excimers in the wavelength range of from 120 to 400 nm and with an energy density below the ablation threshold.
