Will these fit the 38-400 lids?
Yes, these shrink bands can work with 38‑400 lids depending on your bottle and closure dimensions. As outlined in our https://www.tricorbraun.com/blog/shrink-bands-for-bottles-and-jars-a-sizing-guide.html, proper fit is based on the outer diameter of the cap and the height needed to cover the cap and neck opening. We recommend comparing your cap’s diameter to the 66 mm layflat width and confirming height needs, then testing prior to full production.
