As a packaging container, the main function of sealed bottle caps is to prevent oxidation, moisture, insects, etc., extend the service life of food, medicines, cosmetics, etc., and ensure the safety and quality of products. At present, sealed bottle caps have been widely used in various fields, such as medicine, food, cosmetics, health products, etc. Sealing bottle caps are mainly made of two different materials: aluminum and plastic. They have different characteristics and uses.

Sealing bottle cap material: aluminum plate or plastic?

  • Different materials

Aluminum sealed bottles/plastic bottle aluminum caps are made of a composite of aluminum and plastic, while plastic caps are made of a single plastic material. Therefore, aluminum caps for plastic bottles are stronger and more durable than plastic caps, they are also more environmentally friendly because aluminum can be recycled.

  • Different sealing properties

The sealing properties of plastic bottle aluminum caps and plastic caps are also different. Plastic bottle aluminum caps have a ring pattern seal inside, which can better ensure sealing performance and prevent liquid leakage. Due to material limitations, plastic caps have weak sealing performance and are suitable for storing dry items that are not easily affected.

  • Different fields of use

The biggest advantage of the aluminum cover sealing cover is its good sealing performance, which can effectively prevent oxidation, moisture, insects, etc., and ensure the quality of the product. In addition, the aluminum lid sealed box has good texture, strong light transmittance, beautiful appearance, and is easy to produce and process. It is widely used in pharmaceuticals, cosmetics, alcohol, health products and other fields.

Plastic sealing caps are easier to process, lower in cost and easier to use. At the same time, the plastic sealing cover material is also more environmentally friendly, the surface treatment is easier, and it is cleaner and more hygienic. However, the sealing performance of plastic sealing caps is relatively poor, so they are more suitable for some food or daily chemical products that are easy to store or load.

  • Price

There are also differences in cost and price between aluminum caps and plastic caps for plastic bottles. Due to the complex material and high process cost of aluminum caps, the price is relatively high. Plastic covers are relatively cheap due to their low cost.

Sealing bottle cap material

When choosing the material for sealing bottle caps, comprehensive considerations need to be made based on needs. If you want to store products such as easily oxidized substances, high-end alcoholic beverages, health care products, etc., it is best to choose aluminum sealed caps to use its excellent sealing performance to ensure product quality. When we need to store some food that is prone to mold or perishability, it is recommended to choose plastic sealed caps, which are easy to process, use and manage.
