There are numerous factors to take into account when looking at 30ml glass dropper bottles versus PET bottles. Because of their strength and steadiness, glass bottles are most often used for the packaging of top-notch goods. They are unlikely to leach materials and taint the contained liquids. In contrast, PET bottles are much lighter in weight and have a much higher transportation convenience as they are shatterproof. Nevertheless, it is possible that they do not provide the best protection for certain products against the sun’s UV radiation which may degrade the product. Grasping these distinctions will allow you to make better choices based on the subject of your merchandise and the market demands.
