If you want to seek "higher durability," we recommend using a carbide blade.
Cutting film involves three main requirements: 1. a clean finish on the cut surface, 2. durability, and 3. the ear standing up when rolled (suppressing the bulging at both ends).
The cleanliness of the cut surface is primarily determined by the "finish of the blade edge." At Kai Corporation, as a razor manufacturer, we produce high-quality blades, so please take a moment to verify the difference in quality.
*The blade introduced here is a carbide blade that achieves a clean cut surface due to its high edge finish. It is ideal for cutting PET (polyethylene terephthalate), PP (polypropylene), PVC (polyvinyl chloride), and aluminum vapor-deposited films.
Applicable blade: CB-001 32° carbide blade 40mm
