Abstract
The invention relates to uncooked dry or semi-dry sausage products in tubular casings that are based on an optionally-coated textile material. The tubular casing has a longitudinal seam with a sealing strip. On the sealing strip is located a discontinuous layer of a sealing polymer. The sealing strip is bonded to the casing essentially at sealing points defined by the discontinuous layer. The invention further relates to a process for producing the uncooked dry or semi-dry sausage product.
Claims24
An uncooked, dry or semi-dry sausage product comprising a tubular casing comprising a web of textile material, said casing comprising a longitudinal seam having a sealing strip, wherein a discontinuous layer of sealing points comprising a sealing polymer is situated on the sealing strip, said web of textile material is coated directly with a thermoplastic polymeric coating, and said sealing polymer is melted together with said thermoplastic polymeric coating to bond said sealing strip to said web of textile material coated with said thermoplastic polymeric coating,
- the thermoplastic polymeric coating has softening temperature in the range from 80 to 200° C.,
- wherein said coating is a polyether-ester or polyether-block amide;
- and
- if said coating is the polyether-ester, then the sealing polymer is an ethylene vinyl acetate copolymer, and
- if said coating is the polyether-block amide, then the sealing polymer is an aliphatic copolyamide.
The uncooked, dry or semi-dry sausage product as claimed in claim wherein the web of textile material is a woven fabric, knitted fabric or nonwoven.
An uncooked, dry or semi-dry sausage product comprising a tubular casing comprising a web of textile material that has an uncoated weight 30 to 150 g/m2, said web of textile material comprising a direct coating, said direct coating comprising at least one thermoplastic film-forming polymer that has polar or hydrophilic groups, is swellable in water, is not water-soluble and exhibits an intrinsic water uptake, measured in accordance with ASTM E570, test specimen stored in water for 24 hours, of at least 1.5% by weight,
- said tubular casing comprising a longitudinal seam having a sealing strip wherein a discontinuous layer of sealing points comprising a sealing polymer is positioned on the sealing strip,
- the direct coating has a softening temperature in the range from 80 to 200 C,
- wherein said direct coating a polyether-ester or polyether-block amide, the polyether-ester or polyether-block amide having a melt flow index of at least 10 g/10 min, measured at 240° C. under a load of 2.16 kg;
- if said direct coating is the polyether-ester, then the sealing polymer is an ethylene vinyl acetate copolymer
- and
- if said direct coating is the polyether-block amide then the sealing polymer is an aliphatic copolyamide.
