Cutter Poşeti (Katır Bag) is a special vacuum film used in the textile industry on automatic and manual cutting machines. The material is also known as "katır poşeti" and serves as a key component of the fabric vacuum fixation system.

The operating principle is based on vacuum creation: the film covers the fabric layers on the cutting table, after which the system removes air from beneath the film. Atmospheric pressure tightly presses the film against the fabric, making the material layers rigid and stable. This allows the cutting head to perform precise cuts without any fabric displacement.

The film is manufactured from high-strength airtight polyethylene with a thickness of 20, 25, or 30 microns. The film width is 260 cm, enabling complete coverage of large fabric lays. The film can be transparent or have a light matte finish.

The material is mounted on the roll shaft of the cutting machine and is automatically or manually unrolled across the entire length of the cutting table. The katır bag is an essential consumable for high-precision fabric cutting in modern textile manufacturing.
