Five-layer soft tubes are high-performance packaging materials widely used in the cosmetics industry, especially for products with high requirements for shelf life and component stability. The typical structure of a five-layer soft tube is "polyethylene (outer layer) + adhesive layer + barrier layer + adhesive layer + polyethylene (inner layer)." This multi-layer structure provides excellent gas barrier properties, effectively preventing the penetration of oxygen and odor gases, while also preventing the evaporation of the fragrance and active components inside the tube.
1. **Antioxidant Components**
- **Vitamin C**: Vitamin C is highly susceptible to oxidation. Five-layer soft tubes can effectively prevent oxygen penetration, thereby protecting vitamin C from oxidation and maintaining its antioxidant effects.
- **Vitamin E**: Similarly, as an antioxidant, vitamin E can be protected from oxidation and degradation in five-layer soft tubes, extending the product's shelf life.
2. **Active Components**
- **Peptides**: Such as collagen peptides and hyaluronic acid peptides, these components can maintain their activity in high-barrier five-layer soft tubes, unaffected by the external environment.
- **Enzymes**: Such as proteases and lipases, these enzyme components can maintain their biological activity in five-layer soft tubes, preventing them from being destroyed by oxygen and moisture.
3. **Fragrances and Flavorings**
- **Natural Fragrances**: Five-layer soft tubes can effectively prevent the volatilization of fragrances and flavorings, keeping the product's aroma lasting and stable.
- **Synthetic Flavorings**: For synthetic flavorings, five-layer soft tubes can also prevent them from coming into contact with the outside air, avoiding the loss and degradation of the fragrance.
4. **Sensitive Components**
- **Retinol**: Retinol (a vitamin A derivative) is very sensitive to light and oxygen. The high-barrier properties of five-layer soft tubes can effectively protect retinol from degradation.
- **Niacinamide**: Niacinamide can easily degrade in high humidity environments. The moisture barrier properties of five-layer soft tubes can prevent water penetration, maintaining the stability of niacinamide.
5. **High-End Cosmetic Components**
- **Plant Extracts**: Such as green tea extract and grape seed extract, these components contain multiple active ingredients. Five-layer soft tubes can prevent their oxidation and degradation, maintaining their efficacy.
- **Biofermentation Components**: Such as lactic acid bacteria fermentation products, these components can maintain their biological activity in five-layer soft tubes, unaffected by the external environment.
Applications of Five-Layer Soft Tubes
Five-layer soft tubes are not only suitable for protecting the above components but are also widely used in the following products:
- **Serums**: Serums often contain multiple highly active ingredients. Five-layer soft tubes can effectively protect these components, extending the product's shelf life.
- **Eye Creams**: Eye creams contain sensitive components that require high-barrier packaging. Five-layer soft tubes can provide the necessary protection, maintaining the product's stability and efficacy.
- **Face Creams**: Face creams contain antioxidant and active components. In five-layer soft tubes, these components can be protected from oxidation and degradation, maintaining the product's quality.
Conclusion
Five-layer soft tubes, through their multi-layer structure and high-barrier properties, can effectively protect antioxidant components, active components, fragrances and flavorings, sensitive components, and high-end cosmetic components in cosmetics. This high-performance packaging material not only extends the product's shelf life but also enhances the product's quality and user experience.
