Gel-Pak clear membrane boxes
Gel-Pak Membrane Boxes are recommended for devices or large objects that have an irregular shape or non-flat contact surface which will not adhere to Gel material.
Membrane Boxes are constructed using a thin, highly elastic transparent polyether polyurethane membrane mounted to the top and bottom halves of a symmetrical clear polystyrene box. When the box is closed, the device is suspended between the two transparent membranes which conform to the device shape and securely hold it in place.
The high optical transparency of the membrane box packaging allows for inspection and visual checks without having to open up the box. The membrane boxes are reusable and come in a wide range of shapes and sizes.
