Most of the plastic cosmetic tubes currently available on the market are made primarily from PE plastic—whether they are aluminum-plastic laminated tubes with complex structures, or kraft paper tubes and sugarcane-based tubes that emphasize sustainable packaging design, PE plastic remains the core material at their foundation. One might wonder: what exactly makes PE so indispensable in cosmetic plastic tube manufacturing?
In the following sections, we will examine the key properties of PE plastic as a material for cosmetic packaging, analyzing its performance advantages. We will also explore the various processing and customization options available for PE cosmetic tubes, providing you with more valuable guidance for your tube design and sourcing decisions.
1. What is PE Plastic
PE (Polyethylene) is a non-toxic, odorless, milky-white opaque plastic with a wax-like feel and a mild texture, making it widely used in cosmetic packaging. To help you better understand the unique properties of PE, we have compiled a comparison of common plastic property requirements in cosmetic packaging against PE and several other opaque plastics.
As shown in the table above, PE stands out in terms of flexibility, extensibility, and chemical stability. These attributes make it the most suitable material for producing tubes that can be repeatedly squeezed without cracking. At the same time, PE’s good extensibility ensures that PE tubes do not develop fine cracks under repeated stress, preserving the packaging’s appearance to the greatest extent possible.
Depending on its density, PE can be further classified into LDPE (Low-Density Polyethylene), LLDPE, MDPE, and HDPE (High-Density Polyethylene), among others. Different densities offer varying balances of hardness, flexibility, and barrier performance—for example, LDPE is softer and better suited for tubes that require frequent squeezing, while HDPE is more rigid and suitable for containers that require better structural stability and stiffness, such as the commonly seen laundry detergent bottles.
2. Why PE Plastic is Irreplaceable
In fact, beyond container packaging such as cosmetic tubes and laundry detergent bottles, PE plastic is also widely used in the production of plastic accessories including closures, pull-tab seals, and inner plugs. For components like pull-tab seals and inner plugs—where high hardness is not a primary requirement, but sealing performance and flexibility are more critical—PE offers a clear advantage. Its material softness and cost-effectiveness make it a more economical choice for such applications while still meeting functional requirements.
That said, across both containers and accessories, there are scenarios where PE may be replaced by PP or other materials. For example, when hot-filling is required, or higher structural strength is needed, PP is often a better choice for closures.
However, in the specific category of cosmetic tubes, PE plastic remains largely irreplaceable—and this is not just a matter of cost. It is the result of PE’s overall performance in terms of softness, resilience, chemical resistance, and tube-forming processability—attributes that, to date, have yet to be fully matched by any other material.
