We know that the objects packaged in plastic bottles can be divided into solid, liquid and powder. The difference between the packaging characteristics of solid and liquid plastic bottles is an important point I want to talk about today.
About the characteristics of solid and liquid plastic bottles, we carry out targeted analysis from each part. First of all, the diameter of the plastic bottle's mouth, the diameter of the solid plastic bottle is larger than that of the liquid plastic bottle, because the solid product has relatively low sealing requirements, but the diameter of the solid product is often large, which makes the solid plastic bottle to facilitate the product filling line. There must be improvements in the mouth of the bottle. We can see that the wide mouth plastic bottles on the market are mainly used for packaging solid products. Conversely, liquid plastic bottles have higher requirements for sealing performance, and for the convenience of drinking and filling, small-mouth plastic bottles will be used more in the liquid market. Secondly, with regard to the wall thickness and transparency of plastic bottles, the requirements for transparency and wall thickness of plastic bottles for solid plastic bottles are not high. However, liquid plastic bottles have higher requirements for wall thickness. There is a certain pressure on liquid products, and plastic bottle packaging is required to withstand the pressure. This requires liquid plastic bottles to reach a certain wall thickness to be able to withstand the pressure of the product. Liquid products also require transparency of plastic bottles. Some liquid products are sensitive to light, so you must pay attention to your design.
The difference between liquid and solid plastic bottles is basically focused on the details of the product. I hope that our manufacturers can pay attention and treat them.
