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.

Directly attaching, halogen-free, fast-drying, heat-sealing binder for sealing polyester films to polystyrene, polyester or PVC

A transparent, heat-sealable coating for transparent PET packaging foils can be provided by using a heat-sealable lacquer based on styrene-containing copolymers, on poly(meth)acrylates, on at least one polyester and optionally on a tackifier, and also the process for the sealing of a foil coated with this lacquer. It is surprising here that, despite the use of a rubber based on styrene-containing polymers that is not optically compatible with polyesters and polymethacrylate, the transparency of the heat-sealable coatings is still very high.

The present invention relates to a novel synthesis of (meth)acrylate-grafted polyesters and their action as compatibilizers.

Synthesis of polyester-graft-poly(meth)acrylate copolymers

The invention relates to a hot sealing system comprised of an olefin polymer or of an olefin polymer A, of a methacrylate polymer B, of a graft polymer A-X consisting of the above-mentioned constituents and of a solvent or solvent mixture. The hot sealing system is characterized by having a high thermal stability and short sealing times.
