In fact, there is no absolute distinction between good and bad packaging materials. The choice of packaging materials for different products according to various factors such as brand and cost is the first consideration. Only the right is the starting point for all choices. So how to better judge whether there should be a plastic bottle or a glass bottle based on the current product, then let me share some of the differences between the two and their advantages and disadvantages.

Advantages of plastic bottles

Compared with glass products, plastic bottles have lower density, light weight, adjustable transparency, and are not easy to break; plastic bottles have better corrosion resistance, acid and alkali resistance, impact resistance, and have higher mechanical strength and are easy to shape. , The production loss is low. Plastic products are easy to color, and colors can be adjusted according to needs. It is easier to achieve packaging design requirements. The most important thing is that plastic bottles have relatively low costs compared to glass bottles.

Disadvantages of plastic bottles

The disadvantages of plastic bottles are also obvious. People’s first impression is that they are not environmentally friendly. Plastic materials are prone to chemical reactions with cosmetics, which can easily cause cosmetics to deteriorate. The overall look is relatively cheap and not suitable for high-end routes.

Advantages of glass bottles

1. The composition of glass is relatively stable, and it is not easy to produce chemical reaction with skin care products. Generally speaking, skin care products are packed in glass bottles, which are not easy to deteriorate.

2. Glass bottles have a sense of luxury. The main marketing of skin care products sold by merchants are two concepts: appearance + effect. Transparent glass bottles often convey a sense of luxury to consumers, and they are filled with some transparent or colorful products. The skin care products look great

3. The weight of the glass bottle is heavier, more weight in the hand, and more material.

4. Glass bottles are more convenient and more thorough than plastic bottles for disinfection. The easiest and most thorough way to disinfect plastic bottles and packaging materials is to wash them with water and then bake them at high temperature for disinfection. The glass bottle can be washed and baked without any problem, because the glass is resistant to high temperatures.

Disadvantages of glass bottles

Glass materials are more expensive than plastic materials, so the cost of using glass bottles for skin care products is relatively high. The glass bottles are easy to accidentally break, and all the skin care products inside will be scrapped, which is too easy to waste. The glass bottles are fixed in shape and large in size. It is heavy and not easy to carry when going out.
