1. The sealing
The PET plastic bottle should have good tightness, and the mass loss rate of its contents is <1%; Co2 loss rate <15%. The air permeability of a PET plastic bottle with high barrier properties is less than 0.071%mg/(kg.24h. 0.1mpa). Vapor permeability <0.1g/24h.
2. Drop performance
Inject carbon dioxide aqueous solution of nominal capacity of PET plastic bottles, are stored in (21-25), (3-5) 24 h, free drop height is 2 m, fell behind the bottle is not broken, not broken, do not loose bottle base, bottle can still stand.
3. Base bonding.
A PET plastic bottle with a pedestal, its pulling force >90n; Its torsion distance is >8.5N.m.
4. The light transmittance
The transmittance of PET plastic bottle was >85% and fog <3%.
