“…'Overtreatment' is sometimes thought to be a signi cant problem in the use of corona treatment in many practical applications [6,7]. However, overtreatment can only be de ned in the context of what is adhered to the corona-treated surface.…”

The effects of low-molecular-weight oxidized materials generated by corona treatment on the adhesion properties of polypropylene (PP) lm were investigated by adhering four different materials to the modi ed PP: a polyamide printing ink, vapor-coated aluminum, a synthetic-rubber pressure-sensitive adhesive, and an acrylate-based pressure-sensitive adhesive. The low-molecularweight materials enhanced the adhesion of the ink and acrylate-based material, but hindered the adhesion of the metal and the rubber-based adhesive. This seemingly contradictory adhesion behavior can be readily explained using the principles outlined by Brewis and Briggs in the 1980s.

“…This was in contrast to the corona treatment to conventional olefin polymers that the higher corona energy gave the higher polarity until reaching the saturation. 29 The C1s spectrum of PLA/PBS blend sheets ( Figure 2) could be curve-fitted with three peak components. The C1s component at 284.9 eV corresponded to the aliphatic carbon (-CH 3 ), the C1s at 287.0 eV was attributed to the carbon at (-CH-), and the C1s at 289.7 eV was attributed to the constituting ester group (-C¼O-) of PLA, which slightly shifted from the published values.…”

This research developed antibacterial food packaging sheets from biodegradable poly(lactic acid)/poly(butylene succinate) 90/10 wt% blend. The corona discharge energy via input current (in A) was set at three levels (4, 5, and 6 A) to investigate its influence on the coating content. Physical and chemical characteristics of treated surfaces were studied using scanning electron microscope, X-ray photoelectron spectroscopy, and contact angle measurement. A simple dip coating was carried out by immersing the sheets in chitosan solutions with four different concentrations (0.25, 0.50, 1.00, and 2.00% w/v). Chitosan content, antibacterial activity, and water vapour transmission rate were evaluated. Tensile tests were performed and results were statistically analyzed. We found that the sheets treated at 4 A corona discharge energy obtained the highest chitosan content while the sheets maintained elongation at break values similar to the untreated sheets. Chitosan coating had some water vapour permeation barrier and also mechanically reinforced the corona-treated sheets. Antibacterial activity tests against Staphylococcus aureus and

“…This change in surface polarity has been widely studied for increases in adhesion, wettability, printing, and as the subject of this chapter, dyeing. Several excellent reviews are referenced here that detail the specific and mechanisms of the treatment (Nitschke, 2008;Podhajny, 1987;Zhang, Sun, & Wadsworth, 1998}). Fig.…”
