Custom Cosmetic Tube

The packaging materials commonly used for cosmetic tubes include plastics and aluminum. Here are some commonly used materials for cosmetic tube packaging: Plastic Materials: Common plastic materials used for cosmetic tubes include polyethylene (PE), polypropylene (PP), ethylene vinyl acetate (EVA), polyvinyl chloride (PVC), and more. They offer characteristics such as lightweight, durability, transparency or translucency, and are often used to package various types of cosmetic products. Aluminum Materials: Aluminum tubes are commonly used for high-end cosmetic products. Aluminum provides excellent barrier properties, effectively protecting the contents from oxygen, moisture, and external contaminants. Aluminum tubes often have a metallic appearance and can be printed and decorated to display brand logos and information.   It is worth noting that in recent years, sustainable and environmentally friendly materials have also been applied in cosmetic tube packaging, such as recyclable plastics and biodegradable materials.   RUNK: We are China Plastic Tube Packaging factory.

In the cosmetics industry, plastic cosmetic tubes are often heat-sealed to ensure the tightness of the packaging. The following are the sealing steps for plastic cosmetic tubes:   1.Prepare the plastic cosmetic tubes and fillings: Firstly, fill the cosmetic product into the plastic cosmetic tubes, ensuring that the quality and quantity of the filling meet the requirements. This may involve using automated equipment or manual operation. 2.Preheat the plastic cosmetic tubes: Before the sealing process, it is usually necessary to preheat the plastic cosmetic tubes. This can be done by exposing the tubes to the appropriate temperature, typically through hot air or hot water. 3.Seal the tip or nozzle: For plastic cosmetic tubes, the seal is typically applied to the tip or nozzle. This involves exposing the tip or nozzle of the tubes to a heat sealing machine's heating element to soften the plastic. 4.Sealing operation: Once the plastic is softened, the heat sealing machine will heat the tip or nozzle area and apply appropriate pressure to seal the plastic. This creates a sealed area, preventing leakage or contamination of the cosmetic product. 5.Cooling and solidification: After the sealing is completed, the plastic needs to cool and solidify to ensure the stability and integrity of the seal. This typically takes some time, depending on the materials used and the sealing performance.   RUNK: We are China Plastic Tube Packaging factory.
