What Are The Common Materials Used In Airless Pump Bottles Pp Acrylic Petg

Introduction

When choosing cosmetic or skincare packaging, one of the most important decisions is selecting the right airless bottle material. The material affects how well your formula is protected, how the product looks on the shelf, and ultimately, how customers perceive your brand. In this guide, we break down the most common materials used in airless pump bottles—PP, Acrylic, and PETG—so you can make an informed decision based on function, cost, aesthetics, and sustainability.

What Is an Airless Bottle and Why Is It Popular?

An airless bottle is a vacuum dispensing system that prevents air from re-entering the container after each pump. Unlike traditional dip-tube pumps, airless bottles use atmospheric pressure and a piston mechanism to push the product upward.

Key advantages of airless packaging include:

Protects active ingredients from oxidation and contamination

Ensures precise dispensing without product waste

Reduces contact with fingers and air exposure

Suitable for thick or high-viscosity skincare products

This type of packaging has become widely used in skincare serums, foundations, moisturizers and cosmeceutical formulations.

Polypropylene (PP): Practical and Cost-Effective

PP (Polypropylene) is the most commonly used material for the inner container and pump components of airless bottles.

Advantages of PP for airless packaging:

Excellent chemical resistance, suitable for different formulations

Lightweight and durable, ideal for large-volume shipments

Flexible molding capability for complex pump structures

Cost-effective for mass production

Recyclable, supporting sustainability goals

HTX PACK helped a client switch to PP-based airless pump components and achieved a 20% reduction in packaging cost without affecting performance.

Acrylic (PMMA): Premium Appearance and Luxury Texture

Acrylic is often used for the outer shell of airless bottles due to its glass-like clarity and high-end appearance.

Why brands choose acrylic:

Crystal-clear transparency enhances product visibility

Rigid structure conveys a premium look and feel

UV-resistant to help protect formula integrity

Can be colored, frosted or metalized for brand differentiation

Acrylic is a popular choice for high-end skincare lines and retail-oriented packaging.

PETG: Tough, Clear and Sustainable

PETG (Polyethylene Terephthalate Glycol) offers a balance of durability and visual clarity.

Benefits of PETG:

Clear like acrylic but more impact-resistant

Ideal for e-commerce brands due to reduced breakage

Suitable for creative shapes and customization

Recyclable and considered more environmentally friendly

HTX PACK recently upgraded a client’s airless bottle series to PETG, and breakage during transportation decreased by 30%.

Other Material Options: Aluminum and Glass

Although less common, some airless bottle designs incorporate aluminum or glass, especially in luxury or eco-focused product lines.

Aluminum provides strong barrier protection and a modern appearance

Glass offers a luxurious, sustainable and fully recyclable option, but is heavy and fragile
