VP Series Bag Opening Vacuum Suction Cups & Fittings
VP Series Bag Opening Vacuum Suction Cups & Fittings
VP series vacuum suction cups for packaging and bag-opening applications. Choose white silicone, black NBR, antistatic silicone or dedicated male screws.
VP Bag-Opening Cups Are Not the VP Miniature Range
This page lists VP06 through VP50 bag-opening cup labels and separate dedicated screws. Keep the B-series material suffix: a VP bag-opening model is not identified by the VP prefix alone.
| Listed option | Selection check |
|---|---|
| VP...BS / BN / BSE | Listed as white silicone / black NBR / black antistatic silicone. Match the exact size and cup profile. |
| Single M4 Male Screw | Labelled for VP10B. It is a fitting-only selection, not a suction cup. |
| Single M5 / M6 Male Screw | Labelled for VP20-50B. Match the complete screw label and mounting drawing. |
For bags and film, test sealing and release with the actual material and opening motion. Do not substitute a VP 1-4 mm RMS/RMN/RMSE miniature cup merely because its series prefix is also VP.

Applications and Suitable Workpieces
VP Series 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
- VP size, BS/B and material suffixes identify different cup geometries and materials; dedicated M4/M5/M6 screws are fittings, not cup substitutes.
- Choose the exact cup geometry and diameter from the model image; small changes in lip shape can affect sealing on thin film.
- Silicone is commonly selected for flexible sealing and wider temperature capability; NBR is useful for wear resistance and lightly oily industrial conditions; conductive models are intended for static-sensitive handling where specified.
- Wrinkling, folds, perforations and very thin film can cause leakage. Test the actual film thickness, vacuum level and cycle speed before production.
