F18/F22/F26/F33 Bag Opening Vacuum Suction Cups & Fittings

F18-F33: Distinguish Standard, Special and Fitting Options

Start with the full selector label, not just the F-series size. Color-coded cups, antistatic-labelled options, special profiles and threaded fittings are different selections on this page.

The Blue F18 Legacy Mold 18MM Complete label is a separate configuration. For film opening, test the lip profile on the actual film and compare leakage and release before replacing a production cup.

Applications and Suitable Workpieces

F18/F22/F26/F33 Bag Opening Vacuum Suction Cups & Fittings: These cups are designed for opening, separating and transferring flexible film, plastic bags and pouch-type packaging without relying on a rigid flat surface.

Recommended applications

• Plastic bags, flexible film, laminated pouches, stand-up pouches and light packaging materials.
• Bag opening, pouch feeding, filling and sealing machines, packaging robots and automated pick-and-place stations.
• Soft or unstable packaged products where a flexible lip or bellows stroke helps maintain contact.

Model and selection notes

• F18, F22, F26 and F33 indicate cup size. Cup-only, premium, soft-edge and fitting variants are not interchangeable; select the complete code.
• Choose the exact cup geometry and diameter from the model image; small changes in lip shape can affect sealing on thin film.
• Use the selected model's stated material information. Color, Premium or Imported wording alone does not establish compound, temperature capability, certification or a performance advantage.
• Wrinkling, folds, perforations and very thin film can cause leakage. Test the actual film thickness, vacuum level and cycle speed before production.
