Disclosed are void-containing polyester shrink films which show excellent density retention upon exposures to high temperatures. The films have high shrinkage and retain their low density after processing under conditions of temperature and moisture used in typical recycling processes. The films are useful for sleeve label and other shrink film applications, and their lower density allows them to be readily separated from soft drink bottles, food containers and the like during recycling operations. Also disclosed is a process for void-containing polyester shrink films having high shrinkage and low density after exposure to elevated temperatures.

Disclosed are novel compositions for the preparation of void-containing articles comprising a polymer matrix and a voiding agent The voiding agent comprises at least one first polymer and at least one second polymer, which are selected on the basis of physical properties such as glass transition temperature, tensile modulus, melting point, surface tension, and melt viscosity. Shaped articles such as sheet, film, bottles, tubes, labels, and sleeves may prepared from these compositions. Also disclosed are polyester shrink films prepared using a voiding agent comprising a novel blend of cellulosic and olefinic polymers. The resulting shrink films have better opacity, lower density, reduced shrink force, and improved printability as compared with most standard voiding agents. The films are useful for sleeve label and other shrink film applications and their lower density allows them to be readily separated from soft drink bottles, food containers and the like during recycling operations.

It consists of a hollow main body (10), composed preferably of a cover (50) attached to a tubular piece (60) containing the food (20), which is supplemented at its open lower end with thrust means (30), which consist of a plunger (80) assisted by a rod (70) that actuates snugly in the interior of said main body (10), determining the issue of said food (20) for its gradual consumption in a metered fashion, as this food (20) passes through multiple holes (40), provided in the closed upper end of the pack, being dispensed in portions of number, size and shapes defined by the holes (40). The pack also has a plunger (2,2′) associated with thrust means (3,3′) and the viscous food issues laterally by way of holes. Particularly applicable to the dispensing of ice creams, with a secure reliable seal, the pack proposed offers a system of consumption that is not only clean but also fun.

The invention relates to a nanometer SiO2 hybrid polyester modified organosilicon non-stick paint. The non-stick paint is prepared mainly by mixing the following components by weight: 50 to 70 parts of a nanometer SiO2 hybrid polyester modified organosilicon resin, 3 to 10 parts of an epoxy resin, 3 to 10 parts of a melamine resin, 3 to 10 parts of a filling material, 20 to 30 parts of an organic solvent, 1 to 5 parts of a non-stick auxiliary agent, 0.3 to 1 part of a polymeric dispersant and 1 to 3 parts of an adhesion promoter. A coating prepared through coating of the non-stick paint has the characteristics of good non-stick performance, good temperature tolerance, excellent chemical resistance, corrosion resistance, high hardness and the like, is especially applicable to non-stick coatings for ferrous baking equipment and a cake mould and accords with relevant FDA and LFGB standards for food contact materials. According to the invention, the technical defect of a high sintering temperature (normally, higher than 380 DEG C) of a conventional fluoro paint is overcome; and the non-stick paint provided by the invention only needs a sintering temperature of about 280 DEG C, so a phosphating film on the surface of a ferrous substrate is protected, resistance to chemical corrosion is improved, and energy saving and environmental protection are realized.

A food container for the storage of left over food or unused portions of food in a refrigerator for subsequent use, the food container having a base member and a securable lid member of semi-rigid material, the lid being snap fit or hingeably secured to the base member, the lid member having indicia incorporated therein identifying the days of the week which allow the user to identify the day upon which food was introduced in the container for storage, which indicia can be reset when the contained food is consumed and the container is reused at a later date.

A thermal food container has an outer body and at least two trays for containing foods, the trays being separate from each other and being contained inside the outer body. An outer closure lid is detachably associated with the outer body, and a thermally insulating element is positioned between the trays and the outer body. Advantageously, the trays are over moulded with a joining ring which joins them to each other, keeping them separate at the point of at least one separation septum. Furthermore, the joining ring is welded and/or glued to the outer body after insertion of said insulating element, so as to form a hermetic joint between the joining ring and the outer body.
