The present invention comprises a single-component binder for heat-sealing applications which can be used for the sealing of polyester foils, in particular of polyethylene terephthalate foils (PET foils) with respect to containers made of polystyrene, of PVC, and of polyester. These polyesters can in particular be polyethylene terephthalate (PET) or polylactic acid (PLA). The binders here feature not only good seal seam strengths but also in particular good transparency and excellent application properties. A substantive aspect of the invention is that the sealing can be achieved without addition of adhesion promoters, in particular without addition of adhesion promoters based on polyvinyl chloride (PVC) or on polyester, and that barrier properties and sealing properties achieved in respect of containers made of PS and of PET are nevertheless at least comparable with, and sometimes better than, those achieved with heat-sealing systems already marketed.

Binder compositions and methods for making and using same are provided. In at least one specific embodiment, the binder composition can include at least one unsaturated compound having two or more unsaturated carbon-carbon bonds and at least one free radical precursor. At least one of the unsaturated carbon-carbon bonds can be a pi-bond that is not conjugated with an aromatic moiety and can be capable of free radical addition. The free radical precursor can be present in an amount of about 7 wt % to about 99 wt %, based on the weight of the one or more unsaturated compounds.
