Key Considerations for Plastic Coextruded Tubes

When selecting or buying plastic coextruded tubes, there are several key considerations to keep in mind. Here are some important factors:

  1. Material: Consider the type of plastic material used in the coextruded tube, such as polyethylene (PE), polypropylene (PP), or polystyrene (PS). The material should be compatible with the intended application and contents.

  2. Barrier Properties: Coextruded tubes are known for their excellent barrier properties. Evaluate the specific barrier requirements needed for your product, such as protecting against moisture, oxygen, or light.

  3. Thickness and Layers: Assess the number of layers and the thickness of each layer in the coextruded tube. Different layers can provide various functionalities, such as enhancing barrier properties, improving stability, or offering printability.

  4. Size and Shape: Consider the diameter, length, and shape of the coextruded tube based on the volume and viscosity of the product to be dispensed. Custom sizes and shapes may be available depending on the manufacturer.

  5. Closure and Dispensing System: Evaluate the type of closure and dispensing system suitable for the coextruded tube, such as flip-top caps, nozzles, or pump dispensers. Ensure they are compatible with the tube design.

  6. Printing and Branding: If branding and product information are crucial, consider the printing options available for the coextruded tube, such as offset printing, silk screen printing, or labeling.

  7. Regulatory Compliance: Ensure that the coextruded tubes meet industry regulations and standards for the intended application, such as FDA approval for food or pharmaceutical products.

  8. Manufacturer Reputation: Choose a reputable manufacturer with a track record of producing high-quality coextruded tubes. Consider factors like manufacturing capabilities, quality control processes, and customer service.

By considering these key factors, you can select plastic coextruded tubes that meet your specific requirements and provide optimal performance for your products.
