Tube Manufacturing Overview
ABL Tubes
ABL tubes, also known as aluminum barrier laminated tubes, combine plastic layers with a thin aluminum foil barrier. Manufacturers select these tubes for products that require exceptional protection from oxygen, moisture, and light. The aluminum layer, typically between 9µ and 30µ thick, provides a robust shield, making ABL tubes ideal for pharmaceuticals, toothpaste, and food packaging. The tube manufacturing process for ABL tubes involves several precise steps:
- Resin selection and preparation: Operators choose and dry plastic resin pellets.
- Extrusion process: Machines heat and push molten plastic through a die to form hollow tubes.
- Cooling and sizing: Water baths or air cooling solidify tubes and ensure uniform dimensions.
- Printing and labeling: Technicians apply brand logos and regulatory information.
- Cutting and finishing: Equipment cuts tubes to length and seals or threads the ends.
- Quality control and inspection: Inspectors test wall thickness, flexibility, leak resistance, and print durability.
ABL laminated tubes offer a metallic luster but have limited printing flexibility compared to other tube types.
PBL Tubes
PBL tubes, or plastic barrier laminated tubes, use multiple specialized plastic layers to achieve barrier properties. These tubes often incorporate ethylene vinyl alcohol (EVOH) as a barrier layer, which limits oxygen permeation. PBL tubes stand out for their flexibility, lightweight structure, and ease of recycling. Manufacturers prefer PBL tubes for cosmetics, personal care, and products with less stringent barrier requirements. The tube manufacturing process for PBL tubes mirrors that of ABL tubes, but co-extrusion technology enables the creation of multilayer plastic tubes with enhanced barrier performance. PBL laminated tubes support exquisite printing and intricate design options, offering strong branding opportunities.
Note: PBL tubes generally provide moderate barrier protection but excel in environmental friendliness and cost-effectiveness.
Laminated Tubes vs. Extruded Tubes
Laminated tubes and extruded tubes differ in both structure and application. Laminated tubes, including both ABL and PBL types, feature multiple layers bonded together—often with adhesives or co-extrusion—to achieve specific barrier and aesthetic properties. Extruded tubes, sometimes called co-extruded tubes, form by pushing molten polymers through a die, creating a seamless, thicker structure.
| Aspect | Laminated Tubes (Adhesive Lamination) | Extruded Tubes (Extrusion Lamination) |
|---|---|---|
| Structure | Thin adhesive or co-extruded layers; can include aluminum or EVOH | Thicker polymer layers; seamless construction |
| Energy & Process | Lower energy, requires curing time, humidity control | Higher energy, immediate use, no curing time |

| Limitations | Sensitive to environmental conditions, thin aluminum may wrinkle | Requires higher heat, thicker structure |
Laminated tubes provide versatility in barrier and design, while extruded tubes offer durability and efficient production for high-volume needs. Co-extruded tubes, a subset of extruded tubes, further enhance barrier properties by integrating multiple polymer layers in a single process.
Construction
Material Layers
Laminated tubes and extruded tubes differ significantly in their internal structure. Laminated tubes use a multi-layer design, combining several materials to achieve specific performance goals. Manufacturers often select these tubes for products that require advanced protection and branding flexibility.
The typical material layers in laminated tubes vary by type. ABL tubes, or aluminum barrier laminated tubes, feature a core aluminum foil layer sandwiched between inner and outer polyethylene (PE) films. This structure provides a lightweight yet robust barrier. In contrast, PBL tubes, known as plastic barrier laminated tubes, utilize multiple PE layers and an EVOH (ethylene-vinyl alcohol copolymer) barrier. This configuration enhances flexibility and improves resistance to oxygen and moisture.
The following table summarizes the typical material layers and their impact on performance:
| Tube Type | Typical Material Layers | Impact on Performance |
|---|---|---|
| ABL (Aluminum Barrier Laminated) | PE inner film, PE outer film, 10μm aluminum foil | Provides good isolation, lightweight (20-30% lighter than all-aluminum tubes), corrosion resistance, oxidation resistance, good printing quality, soft touch, wrinkle resistance, and health safety due to plastic inner wall. Aluminum layer enhances barrier and oxidation resistance while reducing aluminum usage by 80%. |
| PBL (Plastic Barrier Laminated) | Six PE layers, two bonding layers, EVOH (ethylene-vinyl alcohol copolymer) layer | Offers excellent barriers to water vapor, oxygen, and aroma, high flexibility preventing cracking under deformation, high reliability, and suitability for a wide range of applications including cosmetics, pharmaceuticals, and food. EVOH layer significantly improves oxygen and vapor barrier performance. |
Laminated tubes benefit from this multi-layer approach. The aluminum layer in ABL tubes delivers strong isolation and corrosion resistance. The EVOH layer in PBL tubes boosts oxygen and vapor barrier properties. Both types of laminated tubes maintain a soft touch and support high-quality printing.
Extruded tubes, on the other hand, rely on a seamless construction. Manufacturers create these tubes by pushing molten polymers through a die, forming thick, uniform walls. This process results in extruded tubes that are robust and suitable for high-volume production. However, extruded tubes may lack the advanced barrier properties found in laminated tubes, especially when compared to those with aluminum or EVOH layers.
Note: The choice of material layers directly affects tube performance, including barrier strength, flexibility, and suitability for different product categories.
