Applications and Suitable Workpieces
BL Series Plastic Bag 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
- BL30-5, BL40-5 and BL50-5 identify size. White/red silicone, black NBR, premium, cup-only and complete assembly variants must be matched by full code.
- 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.
