How are toothpaste tubes made

Toothpaste tubes are usually made from plastic, laminated materials, or aluminum-based structures, and the manufacturing process depends on the tube construction.

For plastic tubes, manufacturers can start with plastic resin and use extrusion or co-extrusion to create a continuous tube body. For laminated toothpaste tubes, manufacturers start with a multilayer sheet or web, form it into a cylindrical sleeve, and join the edges to create the tube body. Common laminate structures include ABL (Aluminum Barrier Laminate) and PBL (Plastic Barrier Laminate). Pure aluminum tubes use a different forming process again.

After the tube body is made, the manufacturing process generally continues with shoulder and neck formation, decoration or printing, cap assembly, inspection, filling and tail sealing.

The important point is that a toothpaste tube is not simply a piece of plastic folded into shape. Its material structure, barrier layer, dispensing opening, shoulder, cap, decoration and sealing method all have to work together.

This manufacturing logic is also relevant to Cosmetic Tube Packaging, because many skincare, sunscreen, cream and personal-care products use similar tube structures and production technologies.

1. Choosing the Material Structure Comes First

Before a toothpaste tube can be manufactured, the tube structure has to be defined.

Common options include:

• PE plastic tubes
• Multi-layer or co-extruded plastic tubes
• PBL tubes
• ABL tubes
• Aluminum tubes

The choice depends on the product formula, required barrier properties, dispensing behavior, appearance, production requirements and sustainability objectives.

For example, some toothpaste tubes use multilayer plastic structures, while ABL tubes contain an aluminum barrier layer. PBL tubes use a plastic barrier structure instead of aluminum.

This is important because the manufacturing process is different for each construction.

A tube manufacturer therefore does not normally start by asking only:

“What size tube do you need?”

The technical questions may also include:

• What is the product?
• What is its viscosity?
• Does it require strong oxygen or light protection?
• What dispensing opening is required?
• What filling equipment will be used?
• What type of sealing is required?
• What decoration process is preferred?

The answer to these questions helps determine the appropriate toothpaste tube packaging structure.

2. How Are Plastic Toothpaste Tubes Made?

Plastic toothpaste tubes can be manufactured through extrusion or co-extrusion.

The process begins with plastic resin.

Depending on the specification, different grades of polyethylene can be used for the tube structure. Colorants or other approved materials may also be incorporated into the plastic formulation.

The resin is fed into an extruder, where it is heated and pushed through a die.

The die forms the material into a continuous hollow cylindrical sleeve.

The basic process is:

Plastic Resin → Heating → Extrusion → Cooling → Sizing → Cutting

The continuous tube is then cut into individual lengths.

For a multi-layer tube, co-extrusion can form several layers together. Each layer can have a different function, such as providing structural properties, flexibility or barrier performance.

This is one reason modern tube packaging can be engineered rather than simply manufactured as a single layer of plastic.

3. How Are Laminated Toothpaste Tubes Made?

Laminated tubes follow a different manufacturing route.

Instead of starting with a continuous extruded tube body, the manufacturer starts with a multilayer laminate web.

The laminate may contain several layers, with each layer performing a specific function.

For example, the structure can include:

• Outer printable layer
• Adhesive or tie layer
• Barrier layer
• Inner product-contact layer

The laminate is processed as a flat web before being formed into a tube.

A simplified production flow is:

Laminate Web → Printing → Cutting/Forming → Sleeve Formation → Side Seam → Shoulder Formation → Capping

The flat laminate is formed around a mandrel or forming system to create a cylindrical sleeve.

The two longitudinal edges are then joined.

This creates the characteristic side seam found on many laminated tubes.

The side seam is not necessarily a defect. It is a normal result of the laminate tube manufacturing process.

4. What Is the Difference Between ABL and PBL Toothpaste Tubes?

Two important types of laminated tube are ABL and PBL.

ABL — Aluminum Barrier Laminate

ABL contains an aluminum foil layer within the laminate structure.

The aluminum layer provides strong barrier properties against external exposure such as light, oxygen and moisture.

This type of structure can be useful when barrier protection is an important part of the packaging specification.

However, because ABL combines aluminum with polymer layers, its recycling pathway can be more complicated than a mono-material plastic structure.

PBL — Plastic Barrier Laminate

PBL uses a plastic barrier structure rather than an aluminum foil barrier.

Depending on the specification, a polymer barrier such as EVOH can be incorporated into the structure.

This allows manufacturers to develop a tube that combines barrier performance with an all-plastic or predominantly plastic construction.

For brands comparing ABL tubes and PBL tubes, the correct choice should be based on the actual formula, barrier requirement, manufacturing process and target-market recycling considerations.

There is no single structure that is automatically correct for every toothpaste or cosmetic product.

5. How Is the Tube Shoulder Made?

The tube body alone cannot dispense toothpaste.

The upper part of the tube needs a shoulder, neck and dispensing orifice.

This part connects the flexible tube body with the cap.

Depending on the tube construction and production equipment, the shoulder can be formed or attached using different manufacturing methods, including injection or compression molding and other joining processes.

The shoulder needs to be properly connected to the tube body because it affects:

• Product flow
• Tube strength
• Cap compatibility
• Opening size
• Sealing performance
• Consumer dispensing experience

The neck also needs to match the selected closure.

For example, a screw cap and a flip-top cap require different closure interfaces.

This is why the tube body, shoulder, orifice and cap should be developed as one packaging system rather than as completely independent components.

6. How Is Toothpaste Tube Printing Done?

After the tube structure has been formed, decoration can be added.

Printing is one of the most visible stages of tube manufacturing because the tube carries important brand information.

Depending on the tube construction and required appearance, manufacturers may use different decoration technologies, such as:

• Offset printing
• Flexographic printing
• Silk-screen printing
• Hot stamping
• Other surface decoration processes

For laminated tubes, printing can be performed on the laminate web before the web is formed into a tube.

This means artwork positioning needs to be considered together with the future side seam.

The design team may need to define:

• Front panel
• Back panel
• Side area
• Seam area
• Barcode position
• Regulatory information
• Logo position

This is also highly relevant when developing custom cosmetic tubes.

A design that looks correct on a flat screen may not look correct after the material is formed into a cylinder.

7. When Is the Cap Added?

Once the shoulder and neck have been completed, the closure can be assembled.

Common toothpaste tube closures include:

• Screw caps
• Flip-top caps
• Hinged caps
• Other customized dispensing closures

The cap needs to match the tube neck and dispensing opening.

During production, manufacturers may also check the closure's fit, opening behavior and torque where applicable.

A properly selected closure should provide a practical balance between:

Easy opening + secure closure + controlled dispensing + package appearance

For children's products or products designed for frequent daily use, closure design can also influence the overall user experience.

8. What Happens After the Empty Tube Is Made?

A common misunderstanding is that tube manufacturing and toothpaste filling happen at exactly the same stage.

In many conventional tube supply chains, the tube manufacturer produces the empty finished tube first.

The empty tube may already have:

• Tube body
• Shoulder
• Neck
• Dispensing orifice
• Printing
• Cap

The finished empty tubes are then shipped to the toothpaste manufacturer or contract filler.

The toothpaste is filled through the open tail of the tube.

After filling, the bottom section is sealed.

The general filling process can be simplified as:

Empty Tube → Product Filling → Weight/Volume Check → Tail Sealing → Inspection → Packing

This is important for B2B buyers because the tube manufacturer and the filling factory need compatible specifications.

The tube's tail dimensions, sealing area and material structure need to match the customer's filling and sealing equipment.

9. How Are Toothpaste Tubes Sealed?

After toothpaste is filled into the tube, the open tail must be closed.

The sealing method depends on the tube structure.

For many plastic and laminated tubes, heat-based sealing is commonly used.

The tube tail is placed into the sealing equipment, where controlled heat and pressure create the final seal.

The finished seal needs to provide sufficient integrity for:

• Transportation
• Storage
• Handling
• Consumer use

The sealing process also needs to be compatible with the tube material.

This is why the filling factory should not simply change sealing temperature or pressure without considering the tube manufacturer's specifications.

For a new project, it is better to confirm the appropriate sealing parameters during sample and filling-line testing.

10. How Are Toothpaste Tubes Tested?

Manufacturing does not end when the tube comes out of the production line.

Quality control can include different checks depending on the project.

Typical inspection areas may include:

Appearance

Checking printing, color, scratches, contamination, dents and other visible defects.

Dimensions

Checking tube diameter, length, shoulder dimensions, neck dimensions and other specifications.

Cap and Closure

Checking fit, opening and closing performance and other relevant closure characteristics.

Seam Quality

For laminated tubes, the longitudinal seam needs to be properly formed.

Seal Integrity

The finished tail seal needs to meet the project's requirements.

Dispensing

The package should be tested with the actual product where appropriate.

This is particularly important because a tube can look perfect when empty but perform differently when filled with a real toothpaste formulation.

11. Why Does Toothpaste Tube Manufacturing Matter to Cosmetic Packaging?

Although toothpaste is an oral-care product, the manufacturing technology is closely related to many cosmetic tube applications.

The same basic tube technologies can be used for products such as:

• Facial cleansers
• Hand creams
• Body creams
• Hair products
• Sunscreen
• Masks
• Treatment creams
• Makeup products

For example, a skincare brand may use a PE tube for a standard cream, a barrier laminate for a formula requiring additional protection, or a specially decorated laminate tube for a premium product.

This makes toothpaste tube manufacturing a useful example for understanding the wider cosmetic tube packaging industry.

The exact material and structure should always be selected according to the specific cosmetic formula and packaging requirements.

12. Are Toothpaste Tubes Recyclable?

This question does not have one universal answer.

Historically, many toothpaste tubes were made from mixed-material laminates, including combinations of plastic and aluminum. These structures can be difficult to process in conventional recycling systems.

However, recyclable plastic tube technologies have developed significantly.

For example, Colgate-Palmolive developed a recyclable HDPE-based toothpaste tube and worked with the Association of Plastic Recyclers to obtain recognition for its design. The company says that by the end of 2025, approximately 98% of its toothpaste SKUs globally had transitioned to the recyclable tube.

This does not mean that every toothpaste tube is recyclable everywhere.

Recyclability depends on the specific material structure, design, local collection system and recycling infrastructure.

Therefore, packaging brands should avoid making a blanket claim such as “all toothpaste tubes are recyclable.”

Instead, recyclability should be evaluated for the actual package and target market.

13. What Can Cosmetic Brands Learn From Toothpaste Tube Manufacturing?

Toothpaste tube manufacturing demonstrates an important principle in flexible packaging:

The tube is a system, not just a container.

Material structure affects barrier performance.

The tube diameter affects capacity and appearance.

The shoulder affects dispensing.

The neck affects closure compatibility.

The printing process affects brand presentation.

The tail affects filling and sealing.

The final package needs to work across the complete supply chain.

This is exactly why B2B cosmetic packaging development should begin with the product requirements rather than choosing a tube based only on a photograph.

14. The Basic Toothpaste Tube Manufacturing Process

The complete process can be summarized as follows:

Step 1 — Select the material structure

Choose PE, multilayer plastic, PBL, ABL or another suitable construction.

Step 2 — Prepare the tube material

Extrude plastic resin or prepare the laminate web.

Step 3 — Form the tube body

Extrude the plastic tube or form the laminate web into a cylindrical sleeve.

Step 4 — Create the shoulder and neck

Connect the tube body with the dispensing head.

Step 5 — Apply decoration

Print the brand artwork and required information.

Step 6 — Assemble the cap

Install the selected closure.

Step 7 — Inspect the empty tube

Check dimensions, appearance, closure and structural quality.

Step 8 — Fill the toothpaste

The customer or filling facility fills the product through the open tail.

Step 9 — Seal the tail

The filled tube is closed using the appropriate sealing process.

Step 10 — Final inspection and packing

Finished tubes are checked and packed for distribution.

Conclusion

So, how are toothpaste tubes made?

The answer depends on the tube structure.

Plastic toothpaste tubes can be produced through extrusion or co-extrusion. Laminated toothpaste tubes are made by processing multilayer web material, forming it into a sleeve and joining the longitudinal edges. ABL uses an aluminum barrier layer, while PBL uses a plastic barrier structure. After the tube body is formed, the shoulder, neck, decoration and cap are added before the finished empty tube is sent for filling.

The final toothpaste package is then filled through the open tail and sealed.

For cosmetic packaging suppliers, the same manufacturing principles are highly relevant to skincare and personal-care tubes. Understanding how toothpaste tubes are made helps brands better understand why Cosmetic Tube Packaging can be customized in different materials, structures, capacities, finishes and dispensing formats.

The best tube is not simply the one that looks good. It is the one whose material structure, formula compatibility, dispensing performance, filling process, sealing method and design requirements work together as a complete packaging system.
