How to pack mints and keep mints packaging air tight after plastic ban? The best option will be tin box with heat sealing foil to keep air tight with fully recycling or biodegradable material. Comparing the traditional air tight tin style like shrink wrapping, heating foil air tight style will be a bit complex because it needs to adjust the structure of slide tin case to match automatic heating foil machine. Let’s introduce the characters of air tight slide tin case and how to choose suppliers.
Unlike round tin can whose foil could be pasted on lid directly and it wouldn’t be fallen when opening or closing tin, slide tin case should avoid the edge with foil that could tear down the foil when sliding tin. Is there any method that could keep sliding and foil safely? There are three solutions for it. First one is adding metal holder that keeps 4 sides with a hole in the middle area, so it could release more space for heat foil and the slide function wouldn’t be affected. Second one is making reverse tin bottom and then opening a hole in the middle and keeping 4 sides, so it’s the same result. They are both rolled outside bottom and the height is no more than 10mm, so it could ensure the air tight slide tin working well. The last option is three-pieces tin structure that is sliding function on lid and metal holder, metal holder connected tin bottom and lid covered tin bottom. The best area for this new slide tin is on the appearance – rolled inside and smoothly appearance. Pasting the foil on metal holder and then assembling slide tin case one by one, this structure could keep the pretty outside without scratches or dirty that belongs to the premium option. Comparing three options, second slide tin case will be cheaper for mints packaging, but third slide tin case with nice appearance and no size limit for this slide tin case.
