Recyclable bag for flowable materials with multi-layer film
The patent US12043012B2 describes a specialized bag designed for use in a bag-in-box packaging system. This bag features a front panel and a back panel that are sealed together to create a cavity for holding flowable materials. Each panel is constructed from a film that consists of two laminated portions: a first film portion made of oriented polyethylene and a second film portion formed from a five-layer coextrusion. The coextruded layers include a core made of ethylene vinyl alcohol (EVOH) and various polyethylene layers, ensuring compatibility for recycling as polyethylene (PE). The design emphasizes the use of polyethylene throughout, allowing the bag to be branded as recyclable with a single PE symbol.
Additionally, the claims detail specific characteristics of the bag, including the thickness of the film and its layers, which range from 43 µm to 180 µm for the overall film and 2.5 µm to 13 µm for the core. The bag may also include inner ply panels that enhance its structural integrity. Furthermore, the patent outlines the inclusion of a spout for fluid communication, making the bag suitable for various applications within the bag-in-box package, which is housed in a rigid outer container. This innovative design aims to improve the functionality and recyclability of packaging solutions for flowable materials.
