Vacuum sealing strips are widely used in household/commercial
vacuum packaging machines and industrial vacuum equipment. 
The main material is high-grade silicone rubber, which has excellent high 
temperature resistance, tear resistance, aging resistance and high airtightness,
ensuring that the machine will not leak air when vacuuming.
