The nature of polyurethanes allows them to adapt to solve challenging problems, mold into unusual shapes, and enhance industrial and consumer products. The chemistry of polyurethane can be essential for ongoing advancements in environmental care and the efficient use of our natural resources. Polyurethane is a highly versatile material capable […]

Plastic films are lightweight, transparent, unaffected by biological factors, resistant to chemicals and weather conditions, printable, corrosion-resistant, shatterproof, and show resistance to temperature changes ranging from 60 to 200 degrees celsius. In packaging terminology, plastic films are a thin and elastic layer of an organic material. Due to their low […]

Ethylene vinyl alcohol, or EVOH for short, is a thermoplastic that is water-soluble (water-absorbing) and is derived from the copolymerization of ethylene and vinyl alcohol. The structure of this copolymer is resistant to chemicals and has very low permeability to oxygen, aromas, and odors. The percentage of ethylene comonomer in […]

Adhesives are compounds used for sealing and packaging, and they can migrate into food during packaging or storage. The adhesives commonly used in the packaging industry include hot melt polyurethanes, cold seal, pressure-sensitive, and acrylic adhesives, which can be water-based, solvent-based, or solventless. The selection of adhesives should be based […]

The first flexible film Is cellophane, a thin and transparent sheet made from regenerated cellulose. Its low permeability to air, oils, greases, bacteria, and liquid water makes it useful for food packaging. However, cellophane is highly permeable to water vapor, which can be mitigated by coating it with nitrocellulose lacquer. […]

In this article, we will introduce the laminating adhesive for flexible packaging. In the past, packaging may not have been considered very important, but today various products are transported worldwide under different temperature conditions. Therefore, various criteria have been proposed for ideal packaging to ensure it demonstrates a minimum level […]
