Abstract
A packaged product has a food product having an added liquid thereon, and a packaging article at least partially surrounding the food product. The packaging article having a seal layer comprising a member selected from the group consisting of a slip agent and a surfactant. The slip agent or surfactant causes contamination from the added liquid to bead up or wet out, respectively, thereby permitting heat sealing through the contamination with a lower leaker rate than would otherwise be the case.
Claims22
A packaged product comprising:
- (A) a meat product having an added liquid thereon, the added liquid comprising brine;
- (B) a packaging article surrounding the meat product and the added liquid, with atmosphere having been evacuated from between the meat product and the packaging article, the packaging article comprising a film having a seal layer having an outer surface having a surfactant thereon in an amount of from about 0.5 to 500 micrograms per square inch to provide the ability to heat seal through contamination of said heat seal layer caused by said added liquid to reduce leaker rates compared to the leaker rates of packaging articles having heat seal layers that do not comprise the surfactant, and wherein the packaging article is made from an end-seal bag or a side-seal bag.
A packaged product comprising:
- (A) a meat product having an added liquid thereon, the added liquid comprising brine;
- (B) a packaging article surrounding the meat product and the added liquid, with atmosphere having been evacuated from between the meat product and the packaging article, the packaging article comprising a sheet having a seal layer, the sheet having a thickness of from about 5 to 600 mils, the seal layer having an outer surface having a surfactant thereon in an amount of from about 0.5 to 500 micrograms per square inch to reduce leaker rates compared to the leaker rate of a packaged product having heat seal layers that do not comprise the surfactant.
