As packaging applications become more demanding and resin prices continue to increase, film extruders are searching for ways to improve film properties without increasing cost. Calcium carbonate concentrate is often added by many film producers in applications where dart impact strength is an important property and film clarity is relatively unimportant. Typically, these applications include end products such as trash bags, pigmented merchandise bags and heavy duty shipping sacks. The purpose of this study was to examine the effect of the melt index of the calcium carbonate base resin on film properties and to identify, if possible, the best base resin to achieve optimum film properties.
