Vacuum Holding Force
No model-specific numerical holding-force rating has been verified for this BOLTTE listing, so no suction-force value is claimed here. Actual holding force depends on the differential vacuum pressure, effective sealed area, workpiece material and leakage, lip contact, and acceleration or cycle conditions. The basic theoretical relationship is F = ΔP × Aeffective; actual working force may be lower. The Ø40 mm outside diameter is not necessarily the effective sealed diameter. Test the actual film or pouch with the intended vacuum setup, or request a verified test result before final machine sizing.
Fitment Information
The dimensional drawing confirms the dimensions above, but the exact holder interface or thread specification, silicone hardness and unit weight are not confirmed in the available product data. If your holder fit depends on these details, please confirm the exact variant and mounting interface before ordering.
Applications and Suitable Workpieces
BL40-5 Five-Point Star Silicone Vacuum Suction Cup: Designed for opening, separating and transferring flexible film, plastic bags and pouch-type packaging.
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
- BL40-5 uses a 40 mm five-point-star lip. Select white or red silicone according to the listed variant and confirm the actual pouch seal.
- Choose the exact cup geometry and diameter from the model image; small changes in lip shape can affect sealing on thin film.
- Thin films, wrinkles, folds, perforations and unstable contact can cause leakage. Test the actual film thickness, target vacuum level and cycle speed before production.
