Sizing sleeve method

A blister pack consists of a rigid (cardboard or other) bottom liner and a sleeve of a transparent pol5Tner material. The sleeve can either reproduce the packed article contours (blister strip pack, Fig. 2.55b) or be of regular spherical shape (blister bubble pack. Fig. 2.55c). The sleeve is produced by thermoforming and is bonded to the bottom liner by welding. For the blister pack, commonly inhibited film materials and sheets up to 0.15-1.0 mm thick are used. Mainly small-size hardware and tools are packed by this method. The blister pack adds an attractive appearance to the goods, protects reliably against various effects and enables direct observation of the contents by customers. 

Consideration should be given to the stifliiess of the anchors before partial sleeves are specified for anchor alignment during equipment installation. As the anchor size (and thus the stiffness) increases, the ability to move the anchor horizontally in the field decreases. Using partial sleeves for this purpose is not recommended for anchors greater than 1 in. (25 mm) in diameter for this reason, and alternate methods of alignment such as templates should be investigated.
