This disclosure provides novel thermoplastic nanocomposites having monomodal, bimodal, and multimodal mineral particles dispersed within the polymer matrix to provide high performance thermoplastic nanocomposite barrier layer(s). The thermoplastic nanocomposite barrier layer enhances barrier performance to include moisture, water, and oxygen barrier characteristics used in consumer and industrial packaging applications. Mineral fillers, such as clay nanoparticles combined with micro and colloidal diatomaceous earth, such as calcium carbonate being one example. Bimodal and multi-modal particle combinations can play a significant role in improving intercalation and exfoliation of nanoparticles within the thermoplastic matrix during the compounding and extrusion. The present disclosure includes descriptions of thermoplastic nanocomposites as part of blown films, paper extrusion coatings, and extrusion laminations. The barrier layers may be part of single and multi-layer thermoplastic layers used as films and paper coatings in the range of about 6 to 600 g/m2.

A vapor-deposited substrate is formed by forming a vapor-deposited layer on a substrate. The substrate is a polyolefin resin film containing recycled resin, and the recycled resin is a chemically recycled resin. A packaging material laminate includes the vapor-deposited substrate and a sealing layer.

A container including a tray and a lidding film is provided. The lidding film is removably coupled to the tray and includes a breakable layer, a lidding layer coupled to the breakable layer, and a PSA layer.
