DE3720256A1 - ARTIFICIAL BOWEL WITH AN INNER LAYER OF POLYVINYLIDE CHLORIDE - Google Patents

Abstract

An artificial casing for meat products is formed from a multilayer sheet of heat shrinkable nylon and polyvinylidene chloride. The polyvinylidene chloride layer is located on the inside of the casing adjacent to the meat product. The polyvinylidene chloride layer tends to stick to the meat product, so reducing the possibility of separation of the meat and casing when the casing expands and contracts during cooking and cooling of the product. The layer of nylon may have an outer layer of polyethylene.

Description

The invention relates to a in the packaging of Meat products, ham or the like.

In the past, nature became natural for such applications intestines used which were obtained from animal intestines. Nowadays, however, shrinkable art is usually used material materials because it was difficult on the one hand to get larger amounts of natural casings and secondly Natural casings meet the need for large machine productions cannot cover.

Compared to natural casings, on the other hand, artificial casings have on the Basis of shrinkable plastic plastic materials the advantage that they correspond to the extent of the Adapt the product when it is heated, or at a contraction of the meat product resulting from cooling accordingly shrink such that the formation of wrinkles the surface of the packaged product is avoided. There In addition, the plastic material is impermeable, so that Loss of fluid and the ingress of bacteria or other microorganisms that change the meat product can be avoided and thus the durability is extended is.

The artificial intestine according to the invention, which is a shrinkable Has nylon skin that has a film on one surface made of polyethylene or another suitable material points is essentially characterized in that on the opposite surface to that of those with Polyethylene or the like is coated, a layer of Polyvinylidene chloride (PVDC) is glued.  

The edges of this complex film thus formed remain their end face connected or overlapped and have an adhered to their outer surface or glued-on connecting tape overlapping the edges.

The PVDC layer is located on the inside of the artificial intestine net. The connecting band is preferably made of several layers forms, with a shrinkable nylon skin and is on hers Adhesive or adhesive surface with another polyethylene or coated with a similar material, similar to the outside of the artificial intestine.

An essential feature of the invention is the arrangement on the inside of the artificial intestine Materials provided layer or PVDC coating, which adheres better to the packaged meat product and a separation or a gap between the artificial intestine and the meat product prevents even if the artificial intestine shrinks or shrinks expands during heating or cooling of the meat product.

Further goals, features, advantages and possible applications of the present invention result from the following Description of two embodiments with reference to the drawing. All described and / or illustrated characteristics for themselves or in any meaningful combination nation the subject of the present invention, also independent depending on their summary in the claims or their dependency.

Show it:

Fig. 1 shows a possible embodiment of an artificial bowel according to the invention with the ends lying against each other and the edges

Fig. 2 shows another embodiment of an artificial intestine according to the invention with a connection of overlapping edges.

The artificial intestine according to the invention is formed as a multilayer layer 1 , with a shrink-fit nylon skin 2 and an outer layer or coating 3 made of polyethylene and be on its inside a layer 4 glued or adhered to the shrink-fit nylon skin 2 , coating or a film Polyvinylidene chloride (PVDC).

The edges of the multilayer layer 1 forming the artificial intestine remain, either connected to one another at the end face ( FIG. Or overlapping ( FIG. 2); in any case, however, their connection is accomplished by a connecting band 5 arranged on the outside on the polyethylene layer 3 , which is also formed as a multilayer film, with a shrinkable nylon skin 6 and a coating 7 made of polyethylene, which is disposed adhesive on the outer coating layer 3 made of polyethylene of the artificial casing. Selbstver understandable, the connecting band 5 form of the artificial casing pass the multilayer film 1 of any other material , which seals on the outside of the artificial intestine under heat.

Of course, regardless of the invention, additional measures are implemented, provided that these measures does not change the essence of the invention.
