I'm looking for a 220V automatic L-bar type sealer and shrink tunnel packager that delivers fast and efficient packaging solutions. I'm interested in various models, including manual, semi-automatic, and fully automatic options for the L-bar shrink wrap machine, as well as I-bar alternatives. Please provide detailed specifications, pricing, and availability for these machines. Additionally, I'd like to understand the differences between the models you offer, so I can make an informed decision based on my packaging needs. Thank you!
