Abstract: Described are liners for bulk containers such as intermediate bulk containers (IBC) that are abuse-resistant and barrier-providing. The liners are recyclable. The liners have at least one sidewall that is multi-plied and the plies are multi-layered. The liners are preferably metal-free and nylon-free. An outer ply comprises at least one discrete polypropylene-based film layer. Addition of polypropylene α-olefin to sealant and/or polypropylene-based film layers also improves performance. Methods of making and using the liners are also provided.

Abstract: A crop storage bag (1) made is of a high-strength textile (7) material which is extrusion-coated or laminated with a multilayer film (8) that comprises an insecticidal layer (9) in addition to a hermetic layer (10) which prevents oxygen from entering the bag. This oxygen barrier suffocates the insects inside the bag, and the insecticide kills insects that try to bore through the bag.

Abstract: A bag having a front panel and a back panel coupled together through a plurality of seals, defining a cavity structurally configured to retain a flowable material. The panels are formed from a film that has a first film portion and a second film portion laminated together at an interface. The first film portion has an inner surface and an outer surface and includes an oriented polyethylene. The second film portion is a coextrusion having an inner surface and an outer surface. The extrusion has a core, with a first overlying layer on one side of the core and a second overlying layer on a second side of the core opposite the one side. The core includes EVOH. The first overlying layer and the second overlying layer include polyethylene.

Abstract: The packaging material includes a heat-resistant resin layer 2 as an outer side layer, a heat-fusible resin layer 3 as an inner side layer, and a metal foil layer 4 arranged between these layers. The heat-resistant resin layer 2 is made of a heat-resistant resin film having a hot water shrinkage rate of 1.5% to 12% and the heat-resistant resin layer 2 and the metal foil layer 4 are adhered via an outer side adhesive layer 5. The adhesive layer 5 is formed by an urethane adhesive agent containing a polyol, a polyfunctional isocyanate compound, and an aliphatic compound containing a plurality of functional groups capable of reacting with an isocyanate group in one molecule. With this, a packaging material can be provided in which excellent formability can be secured and delamination can be sufficiently suppressed without causing pinholes, etc., even when deep depth drawing is performed.

Abstract: Aspects of the present disclosure pertain to compositions and methods for preparing silk films for use in food packaging. Exemplary compositions of the present disclosure comprise silk films and packaging coatings as a replacement for traditional food packaging, such as single-use plastic packaging, and/or to extend the shelf-life of foods. The natural bio-based silk coatings of the present disclosure may be odorless, low cost, edible, compostable, come from a renewable source, removable from the packaging for recycling, and are biodegradable. In some embodiments, the silk films and packaging coatings may prolong the shelf-life, enhance or maintain the quality and safety, and/or provide indication of and regulate the freshness of food products.
