Abstract: A molding packaging material is capable of ensuring good slipperiness to secure good formability when molding the molding packaging material and is less likely to cause white powder on a surface of the packaging material. The molding packaging material includes a substrate layer as an outer layer, a heat fusible resin layer as an inner layer, and a metal foil layer arranged between the two layers. The heat fusible resin layer is composed of a single layer or a multi-layer. The innermost layer of the heat fusible resin layer is made of a resin composition containing a heat fusible resin, an anti-blocking agent, a slip agent, and a fluoropolymer-based lubricant.

Abstract: Containers (100), for example boxes, envelopes, mailers, and the like containing one or more deployable cushioning sheets (1500) are disclosed. The deployable cushioning sheets (1500) are connected to at least one wall of the containers (100) and can be deployed to be partially outside of the container for cushioning, for example by wrapping, an object (1600) to be packaged. The deployable cushioning sheets (1500) can contain, for example, paper, cardboard, foam, bubble film, or the like, or they can contain combinations of different types of materials. The containers (100) are useful in methods of packaging, storing, and shipping, among other uses.

Abstract: A method for producing an optically machine-readable identifier on a packaging film. The packaging film includes at least one first layer comprising photosensitive substances and at least one second layer arranged at least indirectly on the first layer, wherein, in order to produce the optically machine-readable identifier, a bundled light beam is directed in a specifiable manner onto the first layer, wherein the bundled light beam is at least partially absorbed by the first layer, wherein the bundled light beam brings about a color change in the first layer to produce the optically machine-readable identifier and is locally converted at least partially into thermal energy, wherein the thermal energy results in a local heat transfer to the second layer and causes a thermal reaction in the second layer, whereby an at least optically detectable image of the optically machine-readable identifier is additionally formed in the second layer.
