An elastomer composition having a self-sealing property includes: a blend of at least two solid elastomers, in which “elastomer A” is a polybutadiene or butadiene copolymer elastomer, in which “elastomer B” is a natural rubber or synthetic polyisoprene elastomer, and in which an elastomer A:elastomer B weight ratio is within a range from 10:90 to 90:10; between 30 and 90 phr of a hydrocarbon resin, with phr meaning parts by weight per 100 parts of solid elastomer; and from 0 to less than 120 phr of filler, which includes from 0 to less than 30 phr of reinforcing filler. The composition may be used to form a puncture-resistant layer in an inflatable article, such as a tire. The puncture-resistant layer may be used in combination with an airtight layer to form an airtight and puncture-resistant laminate for the inflatable article.
