PVC shrink bags offer a ready-to-use alternative that's faster and easier to work with if a shrink film spool isn't a good fit for the job. PVC shrink bags don't need cutting or measuring. Just drop in the product, apply heat, and you're done. Domed shrink bags are specifically designed for gift baskets and handled items, offering a shaped top that conforms cleanly over basket handles, while flat shrink bags have a broader range of everyday packaging applications.
