The Amazon Basic Heißlaminiertaschen are supplied in a tailor-made cardboard box, which is also stable enough to be used for storage of the casings. Indication of the film strength is missing, and I can not select the anyway with my cheap no-name unit. From the quality of the films of the price-performance are highly recommended: + They are meticulously crafted: burr-free, dust-free, very stable and strong + They run cleanly through the device + Do not throw bubbles + They are absolutely crystal clear after lamination + It can be cut well after lamination
