The present application provides a storage box lid, a storage box and a method for manufacturing the same. The storage box lid comprises a flexible thin film and a plastic rigid frame. The flexible thin film is prepared from a two-component platinum contented liquid silicone. In the present invention, the storage box, formed by using the storage box lid with the flexible thin film, in combination with a matching box body, can significantly improve the capacity for storing food, so that it can effectively store food larger than the box body. Moreover, the storage box of the present invention does not significantly squeeze the stored food, and the effect is distinctive.

A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.

A tamper evident container includes a base with a base rim adjoining a base hinge panel and a lid with a lid rim adjoining a lid hinge panel. A hinge connects the panels. A frangible line extends from an edge of the lid hinge panel to a first point on the panel and then outwardly to the hinge. The frangible line crosses the hinge and extends inwardly to a second point on the base hinge panel. From the second point the frangible line extends to an edge of the base hinge panel. When the container is initially sealed, the frangible line separates upon the application of an upwardly directed force to a first portion of the lid hinge panel while a second portion of the lid hinge panel is held in a fixed position or moved downwardly. The separation of the frangible line creates two grasping portions that can be used to pull the lid from the base.

A container configured to hold one or more units of a product is provided. The container may comprise a lid and a base. The lid and/or the base may be constructed from a pulp derived from a plant material. For example, the pulp derived from the plant material may be a wood pulp material. A related method is also provided.

A case for a portable electronic device that includes a rigid outer layer and a more flexible inner layer is disclosed herein. The case is a single piece case. The outer layer has openings that extend through the thickness of the outer layer. The openings are connected by a groove in the outer layer. The openings and the groove may be filled by a more flexible material. The inner layer has openings. The outer layer is translucent so that the inner layer may be visible through the outer layer.

Provided is a resin sheet for thermoforming, the resin sheet containing a poly(3-hydroxybutyrate) resin. A difference between a melting point peak temperature and a melting point peak end temperature in differential scanning calorimetry analysis of the poly(3-hydroxybutyrate) resin is 10° C. or more. The sheet has a thickness of 0.15 to 1 mm. The melt viscosity of the poly(3-hydroxybutyrate) resin at 160° C. is preferably 10000 poise or more.

The present invention is directed at poly(ethylene terephthalate)-poly(ethylene naphthalate (PET-PEN) copolymer extruded sheet that is thermoformable and particularly suitable for medical device packaging, as well as medical device packaging made from such PET-PEN sheet material.

A method of thermoforming a container includes forming a lid having a lid rim, and forming a base including a base rim. The method also includes forming a foldable section that joins the lid rim and the base rim and includes a lid hinge panel extending from the lid rim to a hinge and a base hinge panel extending from the base rim to the hinge. The method also includes forming a frangible line that extends from an edge of the lid hinge panel, across a portion of the lid hinge panel to a first point, from the first point across the lid hinge panel to the hinge, across the hinge, across the base hinge panel from the hinge to a second point on the base hinge panel, and from the second point across a portion of the base hinge panel to an outside edge of the base hinge panel.

A non-foil packaging laminate for liquid food packaging comprises a layer of paper or other cellulose-based material, outermost liquid tight, heat sealable layers of polyolefin-based polymers and, vapour-deposition coated onto the inner side of the layer of paper or cellulose-based material, an induction heat susceptible metal coating. Also disclosed is a method for manufacturing of the packaging laminate, a packaging container that is made from the packaging laminate and a method of induction heat sealing the packaging laminate into packaging containers.
