A shippable bundled product including a plurality of paper product rolls each individually packaged by a first package material and arranged relative to one another so as to form a bundle. The bundle is packaged by a second package material. The second package material has a shrinkage factor relative to the bundle of less than zero.

The present invention aims to provide a heat-shrinkable polyester film roll having decreased generation of wrinkles or longitudinal shrink mark. The present invention provides a film roll of a heat shrinkable polyester film, wherein a polyester of the polyester film contains recycled raw material from a PET bottle and an acid component of the polyester comprises isophthalic acid, and the film roll satisfies a specific average value of a shrinkage, specific isophthalic acid ratio, and specific thickness unevenness.

The present invention relates to thermoforming food packaging methods and to dual ovenable thermoformed food packages suitable for cooking food products directly in the package in microwave, conventional and convection ovens. These packages are characterized by good hermeticity, clean peelability, self-venting, very good optics and, if shrunk, a very appealing appearance.

Insulating assemblies having improved thermal seals are provided. The insulating assemblies have an interface between a base portion and a lid that has an angled transitional portion and at least one elevation change. The angled transitional portion advantageously improves lid removability, assembly reusability, and resistance to thermal energy transfer.

An example technique of forming a package includes retaining a package precursor in a support. The package precursor includes a shrink-formable composition and defines an interior volume configured to enclose a component, such as a medical supply. The package may be formed by at least directing a flow of heated medium from a nozzle toward at least one region of the package precursor to cause the at least one region to shrink faster than an adjacent region of the package precursor. In some examples, an example system for shrink-forming a package includes the support and the nozzle.

The invention provides a heat-shrinkable film that has (1) a glass transition temperature (Tg) of 90-140° C.; (2) shrinkage of 12% or less in a main shrinkage direction when treated in glycerin at 80° C. for 10 seconds; (3) shrinkage of 12% or less in a direction orthogonal to the main shrinkage direction when treated in glycerin at 140° C. for 10 seconds; (4) shrinkage of 30%-80% in the main shrinkage direction when treated in glycerin at 140° C. for 10 seconds; (5) a tensile elongation at break of 10% or more both in the main shrinkage direction and the orthogonal direction after aging of 672 hours at 50° C. and 70% RH; and (6) a difference of 5% or less between shrinkage at 140° C. in the main shrinkage direction after aging of 672 hours at 50° C. and 70% RH, and shrinkage at 140° C. in the main shrinkage direction before the aging.

The bottle safety seal may comprise a safety seal that covers the top of a bottle. The safety seal may prevent contaminants from collecting on exposed non-vertical surfaces of the bottle. As non-limiting examples, the contaminants may be from storing the bottle in a warehouse or other storage area where the bottle may be exposed to dust, dirt, spilled liquids, and other substances. The safety seal may be separable from the bottle such that the safety seal may be removed from the bottle prior to pouring or drinking from the bottle. As non-limiting examples, the bottle may be a water bottle, a wine bottle, a soda bottle, or a juice bottle. The bottle safety seal may be particularly suitable for use on 5 gallon water cooler bottles which may present larger exposed surface areas and may spend longer periods of time in storage before being used.

The present patent application relates to a method of manufacturing a multilayered composite film comprising a step of co-extruding at least three layers (a), (b) and (c), of which the layer (a) forms an outward surface of the composite film; the layer (c) forms a surface of the composite film facing or coming in contact with a good to be packaged; and the layer (b) is disposed between the layer (a) and the layer (c). Further, the method includes a step of biaxial orientation of the composite film thus co-extruded. Therein, the layer (a) contains or consists of a thermoplastic resin. The layer (b) contains or consists of a polyvinylidene chloride (PVdC) resin. The layer (c) contains or consists of a resin, preferably sealable, in particular heat-sealable resin. Therein, any crosslinking of the composite film by means of radioactive radiation, in particular by means of beta, gamma, X-ray and/or electron irradiation, is omitted during the manufacturing of the composite film and/or thereafter.

A shape-formable apparatus comprising locking sheets. The apparatus can have a first state in which the apparatus is formable, and a second state in which the apparatus has the desired shape and is substantially less formable than in the first state. The apparatus can further include an envelope defining a chamber, a port positioned to fluidly couple the chamber with ambience, and at least two locking sheets positioned in the chamber in an at least partially overlapping configuration. Each locking sheet comprises a major surface, and at least a portion of each locking sheet can be patterned to include solid regions and open regions, the solid regions being movable with respect to one another within the major surface.

The present invention is directed to packages having a thermoformed product receiving cavity for containing the product formed from a first flexible heat shrinkable film and a lidding film covering the thermoformed product receiving cavity formed from a second flexible non-heat shrinkable film. The present invention also includes an opening tab on each of the two flexible films which are aligned with each other such that each of the tabs has a sufficient surface area facing the other tab but not adhered to it to render each tab readily manually graspable. The opening tab of the first flexible heat shrinkable film includes a distal portion which is curled to improve its graspability.
