Abstract

Blister pack made from transparent PET (Polyethylene terephthalate) has gained popularity for consumer use in the last decade, due to its favorable properties in clarity, toughness, and recyclability. The manufacturing process of this tray-shaped package begins with thermoforming process that involves heating and forming the plastic according to mold‘s shape, then is continued with manual finishing process (cutting and stacking). As it turns out for most thermoformers, the desirable property of PET—which is its tensile strength—is also what makes it very difficult to cut. Although conventional die cutting methods such as kiss-cut and matched metal die are commonly used to cut PET, this poses challenges in terms of changeovers for short run products as well as justification for its escalated running cost due to shorter knife lifetime. This calls the need for more cost-effective method which can alternatively cater to various shapes and lifecycle of products. Therefore, the target of this study is aimed at providing a design of cutting module that is automatic, robust to PET‘s tensile strength, and also programmable with minimum setup time. Galvo CO2 laser cutting was chosen to deliver those objectives and its optimum parameter setting is further experimented and analyzed in this study. This resulted in not only flexible cutting method, but also improvement in cutting quality of PET blisters.
