UK charts are originally supplied unlaminated - it's further down the supply chain that someone adds lamination - and cost. When I worked for Loganair the charts weren't laminated.
I don't like laminated charts: They're bulkier, more difficult to fold whatever way you want, the gloss is an annoyance at night, and need a special marker & method to erase the marker. Plain paper is much easier to deal with. That being said, and more on topic, a week or two ago I ferried a 2001 Baron 58 from Central Florida to Michigan (870nm). It had a Garmin G500/600 glass display and a GNS540 - both with up-to-date databases. I also had an Android pad with (free) downloaded charts. I didn't need to touch a paper chart or document the whole way.
