  Polyethylene suction cups are made from polyethylene, one of the most widely used and lightweight thermoplastics. They have great impact resistance and can be waterproof and moisture-proof. Polyethylene suction cups are commonly used in electronic appliances and packaging machinery. They are used to lift and move flat and smooth workpieces like screens and panels.

Design of suction cups with loops

The design of suction cups involves creating a cup-shaped object that can create a vacuum seal with a flat, smooth surface. The loop component is an added feature that enhances the functionality of the suction cup.

• Materials

  For the suction cup itself, manufacturers use flexible materials that can stretch and return to their original shape. Common options include rubber, silicone, and thermoplastic elastomers (TPE). These materials can create a vacuum seal by deforming to fit the texture of the surface they attach to. They are flexible enough to create seals on both flat and slightly curved surfaces.

  The loop of the suction cup comes in various materials depending on the intended use. If it is for light applications, the loop can be plastic or nylon. For heavier applications, the loop is metal to withstand greater weight and pressure.

• Shape

  The suction cup has a dome or dish shape with a flexible rim. This shape allows it to create a strong vacuum seal on smooth surfaces. The flexibility of the material that makes the rim enables it to conform to surfaces with slight curves.

  The loop is a feature that enhances the functionality of the suction cup. The loop can have a circular, oval, or rectangular shape. It can also be designed to fold flat to allow for easy storage of the suction cup.

• Color Options

  Manufacturers design suction cups in colors that help them blend with their surroundings. However, there are suction cup designs with bright colors to enhance visibility. The loop also comes in various colors for aesthetic purposes or to meet organizational color codes.

• Texturing

  The design of the suction cup may include surface texturing on the loop to improve grip and prevent slippage. The loop may also have padding to make it comfortable to hold or use fingers.

Some suction cup designs have a safety feature that alerts users when the suction has lost grip. It is to prevent the dropping of items the suction cup is holding onto. The loop may have an indicator that becomes visible when the suction grip is weak.
