Capsule plastic bottles are a common packaging container widely used in industries such as pharmaceuticals, health products, and food. So, what is the material of the capsule plastic bottle? In this article, we will introduce the common materials and characteristics of capsule plastic bottles.

The common materials for capsule plastic bottles include polyethylene (PE), polypropylene (PP), polyvinyl alcohol (PVA), polyvinyl chloride (PVC), etc. These materials each have their own characteristics, and suitable materials can be selected according to the specific needs of the product.


Firstly, polyethylene (PE) is one of the common plastic bottle materials. It has good corrosion resistance, acid and alkali resistance, and high temperature resistance, and is suitable for packaging drugs, food, cosmetics and other products. Polyethylene capsule plastic bottles have a smooth surface, good sealing, easy processing and cutting, as well as certain flexibility and wear resistance.

Secondly, polypropylene (PP) is another commonly used material for capsule plastic bottles. Polypropylene has high hardness, high temperature resistance, and corrosion resistance, and is widely used in the pharmaceutical and food industries. Compared with polyethylene, polypropylene capsule plastic bottles have higher heat resistance and weather resistance, making them suitable for packaging products with higher temperatures.

In addition, polyvinyl alcohol (PVA) is a material with good biodegradability, which is used to make the inner lining of capsule plastic bottles. PVA capsule plastic bottles have excellent corrosion resistance and rigidity, making them suitable for packaging products with corrosive liquids.


Another common type of capsule plastic bottle material is polyvinyl chloride (PVC). Polyvinyl chloride has good corrosion resistance, acid and alkali resistance, and high transparency. PVC capsule plastic bottles are commonly used in the pharmaceutical industry for packaging drugs and health products.

In addition, there are other plastic materials that can also be used for the production of capsule plastic bottles, such as polyvinyl aldehyde ester (PETG), polyethylene terephthalate (PET), polystyrene (PS), etc. Different materials have different characteristics and application fields, and can be selected according to the needs of the product.

In summary, there are various types of materials for capsule plastic bottles, each with its own characteristics and applicability. When selecting the material of capsule plastic bottles, factors such as product properties and usage environment need to be considered to ensure their quality and safety. By selecting appropriate materials, the quality and freshness of the product can be effectively protected, meeting the needs of the market and consumers.
