1. Light weight: The density of the plastic bottle
material is smaller, and the plastic bottle is smaller than the glass bottle according to the same volume of the container mass.
2. Low cost: Plastic can reduce the cost of raw materials and is also lighter, so the total price is relatively cheap.
3. Combined with a reliable sealing structure, therefore, the internal liquid can be reliably protected.
4. Has good mechanical strength. The mechanical properties of plastic bottles are slightly lower than glass bottles, but common product packaging is sufficient.
