Problems solved by technology

While such mechanical operations can be consistently reliable, they are limited in speed and flexibility, and their machine elements are prone to wear
These issues become more pronounced with faster converting lines and complex packaging designs
To alleviate these problems, the speed of packaging lines is often limited, and many flexible packages have simple designs that are less functional, aesthetically unappealing, and not desired by consumers

Embodiment Construction

[0057]A package made from a flexible material may include one or more self-folding portions formed by applying activation energy to the flexible material. Flexible materials configured for self-folding may take various forms, such as films or laminates made of one or more polymer layers (and optionally, energy absorbing material disposed in or on the flexible material) . Self-folding describes the behavior of a flexible material that responds to the application of activation energy by causing a fold to form in a defined area of ​​the flexible material without direct contact with a forming surface such as a machine element; specifically, The self-folding behavior is rapid (i.e., fully folded within seconds) and forms distinct folds with relatively small radii (i.e., on the order of millimeters); thus, self-folding is different from that induced by other stimuli (e.g., mechanical stimuli). ), slower material behavior (eg, changing shape over a minute or more), and material beha...

Abstract

A package made from a flexible material, wherein the package includes one or more self-folding portions formed by applying activation energy to the flexible material.

Description

technical field [0001] The present disclosure relates generally to methods of flexible packaging, and in particular, to flexible packaging having one or more self-folding portions. Background technique [0002] Flexible materials can be formed into flexible packaging by converting methods using various combinations of cutting, folding, sealing, filling and closing. These operations are conventionally performed by mechanical machine elements that are in direct contact with the flexible material. While such mechanical operations can be consistently reliable, they are limited in speed and flexibility, and their machine elements are prone to wear and tear. These issues become more pronounced with faster converting lines and complex packaging designs. To alleviate these problems, the speed of packaging lines is often limited, and many flexible packages have simple designs that are less functional, aesthetically unappealing, and not desired by consumers.
