Customizing Your Bulk Aluminum Collapsible Tubes: Sizes, Liners, and Cap Options

Aluminum collapsible tubes are a top choice across cosmetics, pharmaceuticals, personal care, and even food sectors when it comes to premium, eco-conscious packaging,. Not only do they offer excellent barrier protection and sustainability, but they also allow a high degree of customization—making them a smart investment for growing brands.

This guide covers everything you need to know about customizing aluminum squeeze tubes for wholesale, including sizes, internal linings, and cap types that best suit your product and branding needs.

Tube Sizes: Matching Form with Function

Choosing the right tube size starts with understanding your product’s volume and use case. Here are the most commonly requested capacities for aluminum tubes:

l 5ml – 15ml: Great for eye creams, spot treatments, or sample products

l 20ml – 50ml: Ideal for hand creams, ointments, gels, and cosmetics

l 75ml – 100ml: Perfect for facial cleansers, body lotions, hair care, or paint

l 120ml – 200ml+: Used in professional or industrial formats (e.g., adhesives, pharmaceutical creams)

Tube diameter and length are often customizable in wholesale orders, depending on filling equipment and viscosity.

l Liners: Protecting Your Formula

l Since aluminum can react with certain substances, an internal liner is essential. It protects your formula while maintaining aluminum's eco-friendly profile. Common liner types include:

l Epoxy Phenolic Liner: A versatile option used for skincare, creams, and ointments.

l BPA-Free Liner: Ideal for clean beauty, organic formulations, and food-grade products.

l Polyamide Epoxy Liner: Known for superior chemical resistance—suitable for aggressive or medicinal formulations.

l Unlined Options: Available for products that do not require internal coating, usually industrial-grade.

Always conduct compatibility testing between your formula and the liner to ensure product stability and shelf life.

l  Cap Options: Functionality & Aesthetics

l Caps are more than closures—they impact user experience, hygiene, and visual identity. Here are common wholesale cap options for collapsible aluminum tubes:

l Screw-On Caps: Standard and reliable for most products (often in white, black, or metallic).

l Nozzle Caps: Designed for targeted applications like eye gels, acne treatments, or adhesives.

l Flip-Top Caps: Convenient for one-handed use, ideal for lotions and hand creams.

l Tamper-Evident Seals: Recommended for pharma and high-value products requiring trust and safety.

l Child-Resistant Caps: Used for medicines or chemical-based products.

Caps can also be customized in shape, color, and texture to align with your branding.

Branding & Custom Printing

Wholesale aluminum cosmetic tubes offer a smooth surface that supports full-body decoration. You can enhance your brand identity through:

l Offset Printing: High-resolution, up to 6 colors

l Hot Stamping: For metallic effects or logos

l Embossing/Debossing: Adds a tactile, premium touch

l Matte, Glossy, or Brushed Finishes: Tailor the look to your market segment

Minimalist, luxurious, or clinical—aluminum tubes can match your aesthetic with precision.

Customizing aluminum collapsible tubes isn’t just about aesthetics—it's about functionality, product protection, and brand storytelling. Whether you're launching a clean skincare line or packaging pharmaceutical ointments in bulk, choosing the right tube size, liner, and cap ensures your product performs and sells.

By investing in wholesale customization, you're creating packaging that customers trust and remember—while staying sustainable.
