What exactly is a PET cup lid?
A PET cup lid, or "PET material cup lid," is made from polyethylene terephthalate (PET) through injection molding. It's primarily used with plastic and paper cups. Its core function is to seal the rim to prevent leaks and keep out dust and impurities. It's an essential packaging accessory for ready-to-drink beverages like milk tea, coffee, and juice.
Why have PET cup lids become a mainstream beverage packaging option?
The key lies in the properties of PET: it meets food-grade safety standards and releases no harmful substances at room temperature. It offers a strong seal, tightly fitting the rim, and has a wide temperature resistance range (-40°C to 60°C), making it suitable for both cold and warm drinks. Furthermore, PET raw material costs are low, and molding efficiency is high. A single cup lid costs only a few cents, meeting the large-scale production needs of the beverage industry.
What precautions should be taken when using and recycling PET cup lids?
When in use, avoid contact with high temperatures above 70°C, otherwise the material will easily deform and may even release trace amounts of harmful substances. It is not suitable for holding freshly brewed boiling water drinks. When recycling, you must first clean the remaining drink residue in the cup lid and then put it in the "recyclables" classified trash can to avoid mixing with other garbage and affecting recycling.
