Barrier Properties: Standard single-layer plastic tubes offer less protection against oxygen and light permeation compared to laminate tubes (which have an aluminum layer). This can lead to formula degradation over time for sensitive ingredients like vitamins or certain oils.
"Suck-Back" Issue: With some designs, air can be drawn back into the tube after squeezing, which can cause the product to dry out or crust around the nozzle.
Sustainability Concerns: This is the biggest challenge. Traditional plastic tubes are often not widely recycled in curbside programs, contributing to plastic waste.
The industry is rapidly evolving to address the environmental impact of plastic tubes.
Solution | Description |
---|---|
Mono-Material Tubes | Tubes made from a single type of plastic (e.g., 100% PE or 100% PP). These are much more recyclable than multi-layer laminates because they don't require material separation. This is the leading trend. |
Post-Consumer Recycled (PCR) Plastic | Tubes are manufactured using recycled plastic content (e.g., 25%, 50%, or even 100% PCR). This reduces the reliance on virgin plastic. |
Recycling Programs | Some brands partner with organizations like Terracycle to create take-back programs, ensuring the tubes are collected and recycled properly. |
Biobased Plastics | Tubes made from plastics derived from renewable resources like sugarcane (e.g., Green PE). It's important to note that biobased plastics are not necessarily biodegradable; they often recycle just like traditional PE. |
Feature | Plastic Tube (PE/PP) | Laminate Tube |
---|---|---|
Barrier Protection | Good | Excellent (best for sensitive formulas) |
Squeezability | Excellent (soft) | Good (can feel a bit stiffer) |
Opacity | Can be transparent or opaque | Usually opaque/pearlized |
Sustainability | Good (if Mono-Material) | Poor/Difficult to Recycle |
Cost | Generally lower | Generally higher |
The plastic squeeze tube remains a dominant force in packaging due to its practicality, cost-effectiveness, and excellent user experience. The key for brands today is to select the right type of plastic and prioritize mono-material, recyclable designs to meet modern consumer demands for sustainability.
