An insulating beverage cup or sleeve is produced with a foam layer disposed on an inner surface of a food or beverage paper stock. A polyethylene film layer is arranged in a position between a paper stock layer and an inside surface of the beverage container. The foam layer decreases the energy transfer between the beverage and the user's hands allowing the user to hold onto the cup for an extended period of time without causing user discomfort or pain, e.g. greatly extends the hold time of the paper cup. The exterior surface of the beverage cup remains highly printable and predisposed to high quality graphics both before and after cup manufacture.

The invention discloses a method and an apparatus for a food container which includes an inner member (which can be a cup or a bottle) for holding a particulate food; an outer member (which can be a second cup or a second bottle) adapted to receive the inner member, with a space between the inner and the outer members, for a liquid food; where the inner member interlocks with the outer member and openings are provided for the discharge of the liquid food; and the particulate food and the liquid food can be consumed simultaneously by tilting the container towards the mouth of the user to discharge or withdraw particulate food from the inner member and liquid food from the outer member through the aperture.

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.

An LLDPE produced using a single site catalyst, e.g., an LLDPE produced using a metallocene (m-LLDPE), is preferably used in injection moulding of food packaging material, especially closures for food containers. Such materials have been found to exhibit low levels of migration, typically less than 40 mg / dm<2>, e.g., less than 5 mg / dm<2>, and are particularly suitable for use in packaging foods having a high fat content.

A PET-based polyester packaging film capable of weld-cut sealing and heat-shrinkage refers to a film obtained by biaxially orienting a material prepared through block copolymerization of a PET / PETG / polyester elastomer with an epoxy resin and a catalyst. This film eliminates the most serious weak points in physical properties of conventional PET films, and is useful for packaging of books, bottlesets, food containers, etc., for general packaging, packaging of industrial materials, and the like, and is further useful in the field of packing and packaging of daily commodities, civil engineering and construction members, electric and electronic members, and automobile vehicle members, etc. Moreover, this film can be produced through effective use of the huge amount of recycled PET bottles and inexpensive PET for fiber as a prepolymer, and thus is also highly beneficial socially. Still further, even if incinerated after use, this film produces a combustion heat value lower than that of a polyethylene or polypropylene. Thus, this film barely damages incinerators or the like, and emits no toxic gases.
