“…Polymer solutions will give have a good hold over the rheological properties. In knife coating, an excess coating material is applied to the surface of the substrate, and the thickness of the coating is controlled by using a knife or blade [51]. Different configurations such as floating-knife and knife-over-roll could be used for coating.…”

Research into alternative packaging materials is becoming more and more popular as a result of growing eco-friendly concerns regarding the usage of some petroleum-based polymeric packaging materials and coatings, as well as growing buyer demands for products with nutritious quality and extended shelf lives. Barrier coatings made of naturally renewable biopolymers can be applied to paper packing materials. These biopolymer coatings have the potential to replace the current synthetic paper and paperboard coatings, are strong oxygen and oil barriers, and may prevent the unintended moisture transfer in food goods. An appealing method of controlling the growth and spread of microorganisms in food packaging is the integration of antimicrobial compounds into coatings to create active/functional paper-based packaging materials. Here, in this review of the oxygen/moisture barrier, mechanical, and other characteristics of paper coated with bio-based materials. Examples are used to discuss the current and future uses of bio-based material coatings on paper packaging materials to improve barrier performance.

“…Parameters like blade shape, angle, and the rheological properties of the coating solution will affect the coating thickness and amount of coating material [52,53]. In air knife coating, an excess coating material is blown off from the substrate surface by an air jet that comes from an air knife instead of doctor blade [51].…”

“…The incorporation of inert fillers, like silica in order to improve mechanical properties [2] and the erosion resistance of silicone elastomers [7] was shown by many authors, however the use of barium sulphate or silica to improve the degradation and acid resistance has not been described so far. Barium sulphate itself originates from barites (natural barium minerals) as well as from synthetic precipitation reaction of barium carbonate and sulfuric acid [8]. Beyond the excellent chemical resistance, the incorporation of nano-sized barium sulphate in polyurethane elastomers leads to an antimicrobial nature of the resulting polymers [9].…”
