Yes, you can send bottles with Packlink, although keep in mind that, regardless of the material (plastic or glass), you have to be mindful of the packaging.
Every shipment, either national or international, is manipulated at different steps until it is finally ready to be delivered:
Loading and unloading in vehicles > Conveyor belts > Handling in containers > Customs procedures > Inspections, etc.
We strongly recommend to wrap individually each bottles in a way to prevent any contact between them and/or contact with any other item in the shipment. For example styrofoam can be used as separators.
It is a common practise to ship together with bottles any other type of items we strongly recommend to not do that. You need to be mindful that in case of damages, the rest of the articles in the packaging will also suffer damages or get wet.
If you need to send several bottles, the best option is to use adequate packaging. There's several companies exclusively dedicated to provide specialized packaging, so we recommend to acquire a box designed to send bottles, with double corrugated cardboard separators and styrofoam.
