Description

Technical Field

[0001] This utility model relates to the field of packaging bag processing technology, specifically a packaging film cutting device. Background Technology

[0002] The packaging film is mainly made of several different grades of resin mixed and extruded. It has puncture resistance, high strength and high performance. It is used to wrap goods stacked on pallets, making the packaged goods more stable and neat, and with a stronger waterproof effect.

[0003] Because the size of the base plastic film differs from the size of the finished packaging bag, existing packaging films typically have several rows of evenly arranged packaging bag images printed continuously on the plastic film base. Therefore, they need to be cut before use. However, since the size of each packaging bag is different, the distance between the cutting blades needs to be adjusted. The existing cutting devices are quite cumbersome and inconvenient for adjusting the distance between the cutting blades.

[0004] Therefore, we propose a packaging film cutting device. Utility Model Content
