With the increasing health awareness of people, the health level of traditional industrial products is also demanding higher and higher. Many of the bottled food seals we eat in our daily lives are made of PVC. The plasticizer and halogen component of PVC are more or less absorbed by the body with food or drink, and long-term accumulation may endanger the health of the body. TPE materials are free of plasticizers and halogens. TPE can be used instead of PVC and silicone rubber seals for the beer, carbonated beverages, canned cans, etc. that are often consumed in people's lives.The sealing ring of the cap can be directly bonded to the cover (PP/PE/PETG, etc.) to eliminate the manual assembly and prevent falling off into the food.
