Plastic Caps Testing Instruments

A plastic bottle cap or bottle top seals the top opening of a bottle. A cap is typically colorfully decorated with the logo of the brand of beverage. Plastic caps are used for plastic bottles, while metal with plastic backing is used for glass, plastic caps are commonly made from PE or PP, while metal caps are usually made from either steel or aluminum. Plastic caps may have a pour spout. Flip-Top caps like Flapper closures provide controlled dispensing of dry products. Caps for plastic bottles are often made of a different type of plastic from the bottle. Screw on closures is the most common bottle caps. They are easy to apply by several automated types of equipment, or they can be applied by hand. The application torque of closures must be controlled for the closures to perform properly in the field. Closures must be applied tight enough to maintain a seal and to resist closure back-off, but must not be applied so tightly that the end-user cannot remove the closure. Plastic Caps Testing Instruments are used to test the quality of plastic caps used for closing plastic bottles.
