encourage single polymer solutions rather than multi layered
Additional Information
single-layer polymers without adhesives, and unitary molded, solid, and structurally self-supporting plastics are more suited to the needs of today’s applications . The chemical and physical properties of the polymeric materials used to manufacture bag layers are influenced by the molecular structure, polymerization process, stabilization, and processing additives, as well as manufacturing factors such as extrusion conditions. In addition, the physicochemical properties of these materials are affected by factors such as heat, light, oxygen, and sterilization (irradiation) conditions. Single-use bags are generally made from multilayer films and may include variants of PE such as lowdensity polyethylene (LDPE), linear low-density polyethylene (LLDPE), ultralow-density polyethylene (ULDPE), ethylene vinyl acetate (EVA), ethylene vinyl alcohol (EVOH), polyamide (PA), or polyethylene terephthalate (PET)5,7,8. Each layer in these multilayer films contributes to the overall film properties, while resin selection is based on predetermined criteria, such as barrier properties or transparency requirements as not all plastics are compatible with one another, the different polymer layers in a multilayer film structure may express limited interlayer adhesion. This is why the aforementioned “tie layer” is used to provide adhesion between adjacent film layers, helping these different polymer layers adhere.

Increasing public perception
Additional Information
We want to give manufacturers access to more sustainable materials. That way, they can give the end-consumer more confidence about buying products with the knowledge that the material can be recycled and repurposed, or that it has been produced in a way that can help protect our planet’s natural resources.
