Plastic Barrier Laminate Overview
What Is PBL?
Plastic barrier laminate, often called PBL, is a multi-layered packaging material designed to provide strong barrier protection and maintain product integrity. Manufacturers use laminated structures to combine several materials, each offering unique benefits. The outer layer usually consists of polyethylene terephthalate (PET), which gives high strength and heat resistance. The middle layer often features aluminum foil, delivering the highest barrier protection against gases, moisture, and light. The inner layer typically uses polyethylene (PE) to seal the product and prevent leaks.
Laminated plastic is a composite material formed by bonding layers of different substances. This process includes components such as aluminum and low-density polyethylene (LDPE). High-frequency pressing and heating bond these layers together, creating a durable and protective packaging solution.
| Component | Description |
|---|---|
| Outer Layer | Made of polyethylene terephthalate (PET), known for high strength, heat resistance, and excellent barrier against oxygen. |
| Middle Layer | Composed of Aluminum foil, providing the highest barrier performance against gases, moisture, and light. |
| Inner Layer | Typically a sealant layer made of Polyethylene (PE). |
Structure and Materials
The structure of plastic barrier laminate relies on advanced materials that enhance barrier protection and extend shelf life. Manufacturers select materials based on their ability to block moisture, oxygen, and contaminants. Common materials include:
| Material | Contribution to Barrier Properties |
|---|---|
| Polyvinylidene chloride (PVDC) | Provides excellent barrier against oxygen and moisture |
| Polyamide (PA) | Enhances mechanical strength and gas barrier |
| Ethylene Vinyl Alcohol (EVOH) | Offers superior oxygen barrier properties |
| Polypropylene (PP) | Provides rigidity and moisture resistance |
Laminated tube packaging often uses EVOH as a barrier layer, which helps preserve product integrity and extend shelf life. Innovations in laminated tube technology have introduced biodegradable and water-soluble polymers, making recycling easier. Some laminated tubes now use cellulose-based films with high renewable content or starch-polymer blends that offer up to 95% biodegradability. Bio-PE laminates can reduce carbon footprint by 60%, supporting environmental goals.
Manufacturers also develop single-material high-barrier solutions for laminated tubes, which eliminate the need for complex multi-material layers. These tubes can contain up to 55% recycled content, promoting a circular economy. Metal-free laminates provide high barrier protection against moisture, oxygen, and light while remaining compatible with existing recycling streams.
Laminated Tube Making Machine
The laminated tube making machine plays a crucial role in producing laminated tubes with consistent quality and barrier protection. The process involves several steps:
- The machine starts with rolls of laminate feed stock, known as web stock, which contains various polymers and a barrier layer.
- Printing methods such as offset, letterpress, flexographic, or digital printing apply graphics and information to the web stock.
- The printed web stock unrolls and passes through forming rolls, shaping it into a cylinder.
- High-frequency heat fuses the sides of the laminated material, creating a long cylindrical sleeve.
- The sleeve is cut into smaller, uniform lengths at a cutting station.
- The tube sleeve moves to the heading operation, where the machine forms the shoulders using in-line injection or compression molding, or by attaching preformed shoulders.
- In in-line molding, molten plastic forms the tube head, which fuses to the tube body using heat.
Laminated tube production with the lami tube making machine offers several environmental benefits. Tubes are recyclable in various waste streams, and recycling reduces environmental impact. Energy recovery is possible through incineration, further supporting sustainability.
| Benefit | Description |
|---|---|
| Barrier Protection | Prevents moisture, light, air, and contaminants from affecting the product, maintaining quality. |
| Recyclable and Sustainable | Many tubes are recyclable, contributing to sustainability efforts and reducing environmental impact. |
| Product Protection | Protects against UV radiation, temperature changes, and contamination, preserving product integrity. |
Manufacturers focus on developing ecological laminated tube options. These tubes support a circular economy and help reduce waste. Innovations such as surface treatments and coating formulations enhance recyclability. The use of recyclable plastic alternatives reduces hard plastics in circulation, making laminated tube packaging a greener choice.
PBL vs. ABL
Key Differences
Plastic barrier laminate and aluminum barrier laminate both serve as popular choices for laminated tube packaging, especially in cosmetic packaging. However, they differ in several important ways:
- Aluminum barrier laminate tubes provide excellent barrier protection against oxygen, light, and moisture. This high-barrier protection is essential for preserving sensitive products and maintaining product integrity.
- Plastic barrier laminate tubes offer strong barrier protection, but they do not match the superior performance of aluminum in blocking moisture, oxygen, and light. As a result, aluminum laminated tubes remain the preferred option for products that require long shelf life and maximum product protection.
- Laminated tube structures in both types use multiple layers, but plastic barrier laminate often relies on advanced polymers like EVOH for barrier protection, while aluminum laminated tubes use a thin foil layer.
- The shelf life of products in plastic barrier laminate tubes is generally better than in paper laminates, but not as long as in metal or glass containers.
| Packaging Material | Shelf Life Comparison | Barrier Properties |
|---|---|---|
| Plastic Barrier Laminates | Better than paper laminates | Superior protection against moisture and oxygen |
| Paper Laminates | Needs extra processing for performance | Good for dry goods, less effective than plastic |
| Metal and Glass | Longest shelf lives due to impermeability | Impermeable to gases, light, and moisture |
Environmental Impact
The environmental impact of laminated tube packaging depends on the materials used. Aluminum barrier laminate tubes have a recyclability rate of about 30% in major markets. There is no specific data for the recyclability rate of plastic barrier laminate tubes, making direct comparison difficult. However, environmental assessments show that aluminum foil laminates have a higher impact on metal depletion, fossil depletion, and global warming potential than metallized polymer laminates. Metallized polymer laminate tubes reduce metal depletion by 71% and fossil depletion by 21% compared to aluminum foil. The global warming potential of these laminated tubes is also half that of aluminum foil laminated tubes. These findings highlight the environmental advantages of plastic barrier laminate tubes in reducing resource use and emissions throughout their life cycle.
Note: Choosing the right laminated tube depends on the balance between barrier protection, shelf life, product integrity, and environmental considerations.
