Abstract
An article includes a substrate, and a film-based article comprising a non-crosslinked thermoplastic rubber. At least a portion of the film-based article is fixed to the substrate. In particular, said portion of the film-based article is firmly fixed to the substrate by heat sealing at a temperature of 190 to 250° C. for at least 1 second, without using a glue, an adhesive coating, or a corona discharge treatment.
Claims11
An article comprising:
- a substrate, wherein the substrate is made of a material selected from the group consisting of non-crosslinked thermoplastic rubbers, polyamides, polyesters, thermoplastic polyurethanes and combinations thereof;
- and
- a film-based article consisting essentially of a non-crosslinked thermoplastic rubber,
- wherein at least a portion of the film-based article is in contact with the substrate to form a contact area, and at least a portion of the contact area is heat-sealed without using a glue, an adhesive coating, or a corona discharge treatment;
- wherein the heat-sealed contact area between the film-based article and the substrate has a seal strength of at least 5 N/25 mm;
- and
- wherein the non-crosslinked thermoplastic rubber is a thermoplastic styrenic block copolymer, which is selected from the group consisting of styrene-isoprene-styrene block copolymers (SIS), styrene-isobutylene-styrene block copolymers (SIBS), styrene-butadiene-styrene block copolymers (SBS), styrene-ethylene-butylene-styrene block copolymers (SEBS), styrene-ethylene-propylene-styrene block copolymers (SEPS), styrene-ethylene-ethylene-propylene-styrene block copolymers (SEEPS), and any combinations thereof.
