    Abstract: Compositions suitable for fabricating into a self-sealing film comprise (i) 90-99.95 wt.% of a copolymer of ethylene and a vinyl (or hydrocarbyl substituted vinyl) ester of a C.sub.1 -C.sub.30 monocarboxylic acid, (ii) either 0.05 to 10 wt.% of a hydrocarbon resin, or 0.05 to 5 wt.% of polybutylene or polyisobutylene, or a combination of 0.05 to 10 wt.% of the hydrocarbon resin and 0.05 to 5 wt.% of polybutylene or polyisobutylene, provided the combined weight of the hydrocarbon resin and polybutylene or polyisobutylene is not more than 10 wt.% and (iii) 0.01 to 3.0% by weight based on the combined weight of (i) and (ii) of a partial carboxylic acid ester of a polyol, e.g. sorbitan monolaurate.

    Abstract: A transparent self-sealing film suitable for packaging is made from a composition comprising (i) 90 to 99.95 wt. % of a copolymer of ethylene and a vinyl (or hydrocarbyl substituted vinyl) ester of a C.sub.1 -C.sub.30 monocarboxylic acid (vinyl acetate) containing at least 89 wt. % (e.g., 91 to 95 wt. %) of ethylene and (ii) either 0.05 to 10 wt. % of a hydrocarbon resin, or 0.05 to 5 wt. % of liquid polyisobutylene or liquid polybutylene (MW 30,000 to 50,000) or a combination of 0.05 to 10 wt. % of the hydrocarbon resin and 0.05 to 5 wt. % of polyisobutylene or polybutylene, provided the combined weight of hydrocarbon resin and polyisobutylene or polybutylene is not more than 10 wt. %.
