As a result of the robust barrier that this 500ML PVC Bottle builds with the environment outside, no oxygen can enter. Additionally, this container does not react with food or water, making it an excellent choice for packaging consumer items. It is also very resistant to alcohols, aliphatic hydrocarbons, oils, greases, and diluted acids, and only somewhat resistant to dilute alkalis, aromatic hydrocarbons, and halogens. This 500ML PVC Bottle's inability to crack or crush is an additional advantage. It is a safer option because of this feature.
