THIN-WALLED INJECTION MOLDED CONTAINER

摘要

A container is produced with less material compared to blow-molded containers by using an injection molding process using a plastic material, such as polypropylene, having a melt flow index of at least about 100 and a material flow length to wall section ratio of at least about 350 to 1. Because injection molding can hold tighter tolerances than blow-molding, water tight seals can be formed between containers and lids without the need for supplemental sealing materials.
