The difference between solids and liquids in plastic bottle packaging

We know that the object of plastic bottle packaging can be divided into solids, liquids, powders, which are several categories. The difference in packaging characteristics between solid and liquid plastic bottles is a key point that I want to talk about today.

On the difference between the characteristics of solid and liquid plastic bottles, we are targeted from various parts of the sub-analysis. First of all, the mouth of the plastic bottle, solid plastic bottle caliber to be larger than the liquid plastic bottle, because the solid product sealing relatively low requirements, but the solid product diameter is often larger, which makes the solid plastic bottle in order to facilitate the product filling line, it must be improved on the mouth of the bottle.

We can see that the wide-mouth plastic bottles on the market are mainly used to package solid products mainly. On the contrary, liquid plastic bottles require higher sealing performance, and for the convenience of drinking and filling, small-mouth plastic bottles will be used more in the liquid market.

Secondly, regarding the wall thickness and transparency of plastic bottles, solid plastic bottles do not have high requirements for the transparency and wall thickness of plastic bottles. But liquid plastic bottles have high requirements for wall thickness, liquid products have a certain pressure, need plastic bottle packaging to withstand the pressure, which requires liquid plastic bottles to achieve a certain wall thickness to be able to withstand the pressure of the product. Liquid products also have requirements for the transparency of the plastic bottle. Some liquid products are sensitive to light, so in the design must be noted.
