The cosmetics industry depends on packaging solutions to protect products from degradation and lengthen their storage duration while creating better brand images. The selection of appropriate plastic materials for cosmetic tubes represents a major challenge because these products need to protect sensitive formulations through high barrier performance. High-barrier cosmetic tubes serve two main purposes by blocking oxygen and moisture and UV rays while keeping their recyclable design and easy-to-use functionality.
Zhejiang Hongyi Plastic Industry Co. Ltd. stands as a top option for brands who need dependable packaging solutions with customizable options and superior performance. The company provides complete packaging solutions through its R&D capabilities and modern manufacturing equipment and extensive selection of cosmetic tubes.
What Plastics Are Typically Used in High-Barrier Cosmetic Tubes?
High-barrier cosmetic tubes require manufacturers to select plastics through multilayer structures or advanced laminate materials which provide maximum protection for their contents.
Multi-Layer Co-Extruded PE Structures for Enhanced Barrier Properties
High-barrier packaging relies on multilayer co-extrusion technology as its fundamental production method. The main structure of these packages consists of polyethylene (PE) as the primary layer which works together with ethylene vinyl alcohol (EVOH) as the barrier layer. The excellent oxygen barrier properties of EVOH require its use in packaging materials that protect sensitive ingredients from oxidation.
Co-extrusion: The production of multi-layer composite structures through PE/EVOH/PE technology creates structures that enhance barrier properties for food and pharmaceutical packaging applications. The structural design enables different viscosity levels which makes it appropriate for packaging creams and gels and lotions.
Use of Laminated Tubes with Aluminum or Plastic Barriers
The production of laminated tubes involves uniting different materials into one complete structure. The standard structure of these tubes consists of three layers which start with PE on the outside followed by EVOH or aluminum foil in the middle and end with PE on the inside. The designed structure provides outstanding defense against oxygen permeation and UV radiation damage and volatile substance migration.
These materials work best for high-end skincare products which need extended shelf life protection. The barrier system protects active ingredients including retinol and vitamin C from degradation during the entire product shelf life.
Integration of Recyclable Mono-Material PE Tubes
The market shows increasing interest in using recyclable mono-material PE tubes as a new standard. The tubes use a single material type which includes HDPE or LDPE to achieve recycling simplicity while maintaining their barrier properties.
Brands now select materials which are recyclable and biodegradable for their products including PCR (post-consumer recycled plastic) and PLA (polylactic acid) and paper-plastic hoses and sugarcane hoses to minimize environmental damage. The 25 PE plastic tube refilling bottle–1 demonstrates this change through its lightweight leak-proof mono-material structure.
Why Is PE (Polyethylene) a Preferred Material in Cosmetic Tube Manufacturing?
The production of cosmetic tubes depends on polyethylene as their fundamental polymer material. The combination of its versatile properties with chemical resistance and affordable price makes polyethylene suitable for both basic and advanced barrier applications.
Chemical Resistance and Product Compatibility
PE resists degradation from acids, bases, and most cosmetic actives. The tube material remains stable because it does not react with any ingredients in the formulation.
The tube requires protection from chemical reactions with the formulation because this preservation ensures the long-term stability of sensitive emulsions.
Softness and Flexibility for User Comfort
The flexible design of PE provides users with comfortable application experiences. Users can easily apply lotions and gels through the simple squeeze function.
The hose extrusion design allows users to easily manage dosage amounts while providing secure sealing that stops leaks when used repeatedly. The touch-sensitive design stands out most in small travel products including the 19 PE plastic tube refilling bottle–5.
Cost Efficiency and Scalability in Production
PE exists in large quantities and manufacturers can easily transform it through established extrusion and injection molding production methods. The material works well with fast filling production lines which enables business expansion.
The production line at the company has evolved from traditional labor-based manual operations to an automated industrial production system. The automated system enables both quality control consistency and supports intricate printing methods including silk screen printing and hot stamping.

What Role Does Tube Design Play in Enhancing Barrier Functionality?
The design structure of a tube together with its materials determines how well it functions as a barrier. The barrier performance of a tube depends on how its different components including layer thickness and closure systems and surface treatment interact with each other.
Thickness Optimization Across Tube Layers
The protection against gas permeation becomes better when wall thickness adjustments are made without compromising the flexibility of the material. The protection against oxygen permeation improves when EVOH cores reach thicker dimensions because this material works well for oxidation-sensitive formulations.
The method proves most effective for Hongyi’s multi-diameter product line which includes the 25 PE plastic tube refilling bottle–1. The product design provides enhanced durability through its reduced material requirements.
Cap Sealing Systems That Complement Tube Integrity
