Orings are universal sealing elements used to seal against liquid or gaseous median. They are suitable for static and minor dynamic applications. Orings can be used for radial and axial sealing. The sealing occurs during installation by the radial or axial compression of the crosssection. During operation, the median pressure increases the deformation of the Oring and so increases the sealing effectiveness. For best sealing effectiveness, the Oring should have the largest possible crosssection. During installation the correct groove size, compaction, elongation/compression should be ensured. By static use the compaction should be 15 30% of the crosssection. By dynamic use it should be 10 18% (hydraulic), 4 12% (pneumatic). With regard to the ID, when installed the Oring should be stretched max 6% compressed max 3%

O - ring seal as flexible perfection To determine which O - ring can be used , only a few important operating parameters must be defined . The temperature , the pressure and the indication of the chemical resistance determines the selection of the correct O - ring at the right application. O - rings from Billi - seals are distinguished , depending on the material , by high thermal stability, good chemical resistance and good low temperature flexibility.

OPP bag sealing tape is specially designed for high-pressure PE self-adhesive plastic packaging bags. The surface of the product is covered with BOPP release film. Pet is used as the base material and double-sided acrylic glue is used. The product has the advantages of strong glue and weak glue. It is suitable for sealing PE bags with different material thickness. It has good repeatability and the thin bags will not stick. Their designs have lots of advantages including good adherence and retentiveness, recycling usage, and the liner on the tape can be easily removed with finger lift edge on each side of the tape. It is suitable for sealing OPP, LDPE plastic bags.
