Manufacturing Process
The manufacturing process of the 90mm PET/RPET Sip-Through Lid (90K) involves state-of-the-art thermoforming technology. This process begins with high-quality PET or RPET sheets being heated to a specific temperature. The sheets are then formed into the desired shape of the lid using a mold, which ensures precision and consistency.
The use of thermoforming technology allows us to produce lids that are not only durable but also feature a smooth surface and uniform thickness. The gear design around the rim is created during the forming process to ensure a tight, secure fit, while the sip-through hole and straw hole are punched into the lid during post-processing. This careful, multi-step process ensures that each lid is of the highest quality and functionality.
