    • Disclosed is a tubular packaging material to produce a sausage casing comprising a carrier tubing comprised of hydrate and containing in its wall from about 5 to 12% by weight of water and from about 18 to 28% by weight of a plasticizer; an anchoring layer on the outside of the carrier tubing of a water-insoluble heat-cured synthetic condensation product; a film coating on the outside of the carrier tubing which is substantially impermeable to water and water vapor and which comprises a copolymer of vinylidene chloride; and a water-permeable adhesion-promoting layer on the inside surface of the carrier tubing, comprising a water-insoluble, heat-cured condensation product. The carrier tubing is characterized by a swelling value in the range from about 80 to 120%, and the tubular packaging, after soaking in water at a temperature between about 40.degree. to 50.degree. C. for a period of about 30 minutes and subsequent cooling to about room temperature, is characterized by dimensions in the wet state which are about 2 to 6% greater than those before the soaking in water, and wherein the tubular packaging, after simmering or boiling at a temperature of about 85.degree. C. for about 30 minutes and then cooling to room temperature, is characterized by dimensions in the wet state which are about 1 to 3% smaller than the wet state dimensions of the tubular packaging material which has only been subjected to said soaking in water. Also disclosed are methods for preparing the tubular packaging material.
    • 公开了一种用于生产香肠肠衣的管状包装材料,其包括由水合物构成的载体管,并且在其壁中含有约5至12重量%的水和约18至28重量%的增塑剂; 在水不溶性热固化合成缩合产物的载体管的外侧的锚定层; 载体管外侧的薄膜涂层,其基本上不渗透水和水蒸汽,并且包含偏二氯乙烯的共聚物; 以及在所述载体管的内表面上的透水性粘附促进层,其包含水不溶性的热固化缩合产物。 载体管的特征在于在约80至120%的范围内的溶胀值和管状包装,在约40至50℃的温度下浸泡在水中约30分钟并随后冷却 其特征在于潮湿状态下的尺寸比浸泡在水中之前的尺寸大约2至6%,并且其中管状包装在约85℃的温度下煨或沸腾约为约 30分钟,然后冷却至室温,其特征在于湿状态的尺寸比仅经受所述浸泡在水中的管状包装材料的湿态尺寸小约1至3%。 还公开了制备管状包装材料的方法。

    • Disclosed is a process for forming an uninterrupted coating of uniform thickness on the inside of a length of tubing which comprises the steps of forming a loop of tubing with a downwardly inclined portion and an upwardly inclined portion; filling the cavity of the tubing forming the loop with a coating liquid; transporting the tubing along its longitudinal axis in a substantially vertically upward direction to coat the inside of the tubing, above the level of the coating liquid, with an initial layer of coating material; constricting the tubing to lay partially flat along a narrow zone running transverse to the direction of transportation above the level of the coating liquid to retain the greater part of the coating liquid in the constriction zone and form a thin layer of coating liquid of desired thickness on the inside; of the tubing issuing from the constriction zone; filling the cavity of the tubing issuing from the constriction zone with support gas; and exposing the tubing to the action of heat at a sufficiently high temperature to fuse the coating layer to the inside of the tubing and form an uninterrupted film of uniform thickness on the inside of the tubing. Also disclosed is an apparatus for carrying out the process of the present invention.
    • 公开了一种用于在一段管道的内部形成均匀厚度的不间断涂层的方法,其包括以下步骤:形成具有向下倾斜部分和向上倾斜部分的管道环; 用涂布液填充形成环的管的空腔; 沿着其纵向轴线沿着基本垂直向上的方向输送管道,以涂覆涂层液体上方的管道内部,涂覆初始的涂层材料层; 将管道收缩成一定程度上沿着与涂覆液体水平以上的运输方向横向运动的窄区域,以将更大部分的涂覆液体保持在收缩区域中,并形成所需厚度的薄层涂层 里面 从收缩区发出的管道; 用支撑气体填充从收缩区发出的管道的腔; 并在足够高的温度下将管暴露于热作用下,以将涂层熔合到管的内部,并在管的内部形成均匀厚度的不间断的膜。 还公开了一种用于实施本发明的方法的装置。

    • Antimicrobial film based on biopolymers, in particular cellulose and/or protein, or uncoated or coated textile material, and also an antimicrobial sponge or an antimicrobial sponge cloth based on regenerated or precipitated cellulose are provided. The film, the sponge or the sponge cloth is impregnated or coated with at least one α-amino acid ester, the α-amino group of which is acylated with a fatty acid, or the corresponding hydrochloride, and the α-amino acid ester is bound covalently, optionally also ionically, to the film, the sponge or the sponge cloth. The acylated α-amino acid ester is preferably N-lauroyl-L-arginine ethyl ester monohydrochloride (LAECI), N-lauroyl-L-arginine methyl ester monohydrochloride (LAMCI) or N-lauroyl-L-lysine ethyl ester hydrochloride (LLECI). The film is preferably in the form of a flexible tube and is provided as casing for foods, especially sausage products.
