2026 Skincare Tube Sourcing Guide: How to Choose Between ABL, PBL, and EVOH Barriers to Maintain Formula Efficacy?

Foreword: When sourcing skincare packaging B2B, brand owners often face a challenge: how to make the soft tube aesthetically pleasing while perfectly protecting sensitive formulas containing Retinol or Vitamin C? The answer lies in the multi-layer composite structure of the tube. Today, Lumlun will combine 4 hardcore questions frequently searched on Google to help you see through the material science of tube packaging.

1. In-Depth Analysis: What are cosmetic tubes made of?

Modern cosmetic tubes are never single-layer materials, but rather a sandwich-like multi-layer structure. A standard 5-layer high-barrier tube usually consists of the following parts:

• Inner and Outer Layers: Usually made of PE (Polyethylene), which provides customers with a tactile feel, gloss, and safety guarantees for skin contact.
• Core Barrier Layer: Located in the middle layer, it is the key to protecting the formula, usually aluminum foil or EVOH resin.
• Tie Layers: Located on both sides of the barrier layer, responsible for firmly bonding the PE to the barrier material to prevent the tube from delaminating when squeezed.

2. Material Selection: What is ABL and PBL? How should I choose?

This is the most tangled question for sourcing managers. The essential difference between the two lies in the material of the "middle barrier layer":

ABL (Aluminum Barrier Laminate) Tube:

• Middle Layer: Extremely thin aluminum foil.
• Characteristics: Has physical-level 100% barrier properties, which can completely isolate light, oxygen, and water.
• Pain Points: Due to the characteristics of aluminum, it will leave creases after squeezing and cannot bounce back, and it cannot be recycled.

PBL (Plastic Barrier Laminate) Tube:

• Middle Layer: EVOH barrier layer.
• Characteristics: Has excellent resilience, can instantly bounce back after squeezing, restoring the tube's original shape. More importantly, it is more in line with modern sustainability needs for environmental recycling.

3. Core Black Tech: What is the function of EVOH in composite tubes?

Although EVOH is only a thin layer in PBL or some high-end PE tubes, it is still an indispensable part of the tube:

• Locking in Fragrance: Can prevent the aroma of natural essential oils from seeping through the plastic tube wall, ensuring the product still maintains a rich fragrance when it reaches consumers.
• Preventing Degradation: Can stop external chemical substances from penetrating into the tube, protecting the chemical properties of skincare products from changing.
• Enhancing Aesthetics: Compared to ABL, PBL tubes containing an EVOH layer can undergo more complex surface treatments and full-tube printing.

4. Technical Deep Dive: Why is EVOH an excellent oxygen barrier?

For highly active ingredients like Retinol, which lose efficacy upon exposure to oxygen, EVOH plays a crucial role:

• Molecular-Level Barrier: EVOH is a highly crystalline polymer with extremely tight molecular arrangement. This structure has high density, making it extremely difficult for oxygen molecules to penetrate.
• Extending Shelf Life: Studies show that the oxygen transmission rate of EVOH is extremely low, far superior to most general plastics on the market. This can significantly slow down the oxidation rate of oils and active ingredients in the formula, thereby reducing the proportion of preservatives added.

⚡ Quick Decision Guide: ABL vs. PBL Tubes

To help B2B buyers quickly match the right packaging material with their skincare formulas, here is a straightforward comparison:

Conclusion: How to Make a Decision?

At Lumlun, we recommend:

• If your formula belongs to highly active, easily oxidized professional-grade products, the ABL tube is the best choice to guarantee product efficacy.
• If you value brand aesthetics, environmental recycling, and the ultimate squeeze feel, then the PBL tube with a 5-layer EVOH barrier structure is your best choice.
