Squeeze Tube Abrasion Resistance: How to Prevent Your Toothpaste from Rubbing Holes in Its Own Package

You have formulated the perfect toothpaste. The flavor is refreshing, the whitening agents are effective, and the texture is exactly right. You package it in a beautiful laminated tube and ship it to customers. Then, three months later, the complaints start arriving: "My tube is leaking." "There is toothpaste all over my medicine cabinet." "The tube split at the crimp."

What went wrong? You underestimated abrasion.

Toothpaste is not a gentle product. It contains hard, sharp particles designed to scrub stains from teeth. Those same particles, over time, can literally sandpaper the inside of your tube until it develops microscopic holes. This article explains why tube abrasion happens, how to test for it, and how to choose packaging that survives the journey from factory to bathroom cabinet.

Part 1: The Hidden Enemy – Why Toothpaste Destroys Tubes

Every toothpaste contains abrasives. These are the ingredients that provide the "grit" needed to remove plaque and surface stains from teeth. Common abrasive agents include:

• Hydrated silica (the most common abrasive in modern whitening toothpastes)
• Calcium carbonate (chalk; found in many natural toothpastes)
• Dicalcium phosphate dihydrate
• Alumina
• Perlite
• Sodium bicarbonate (baking soda) 

These particles are hard. Really hard. And they are suspended in a viscous paste that gets squeezed, mashed, and moved every time a consumer uses the tube. Each squeeze pushes abrasive particles against the inner wall of the tube. Over hundreds of uses, this repeated friction can wear down the inner layer of the tube until it fails.

According to industry research, toothpaste formulas typically contain 10–40% abrasive agents by weight . That is a lot of sandpaper rubbing against your packaging with every use.

The Abrasion Trio: Hardness, Shape, and Size

Three characteristics determine how destructive an abrasive particle will be to your tube:

The same properties that make a toothpaste effective at cleaning teeth also make it aggressive toward tube materials .

Part 2: Which Tube Materials Resist Abrasion Best?

Not all toothpate tubes are created equal when it comes to withstanding abrasive toothpaste. Here is how the major tube types compare.

Monolayer Plastic Toothpaste Tubes (The Riskiest)

These are single-layer extrusions of polyethylene (LDPE or HDPE). They are cheap—often $0.10\text{–}$0.20 per unit—but they offer the least protection against abrasion.

How they fail: The abrasive particles wear through the single thin wall (typically 150–250 microns) over time.

Failure mode: Pinholes, then cracks, then full leaks.

Best for: Non-abrasive products (lotions, gels, creams). Not recommended for toothpaste with high silica content.

Standard Laminated Tubes (Better)

These are multi-layer structures, typically: Polyethylene / tie layer / aluminum foil / tie layer / polyethylene.

The aluminum foil barrier is impermeable, but the inner polyethylene layer is still exposed to the abrasive paste. Over time, the inner PE layer can wear thin. However, because the aluminum layer is there, the tube may not leak until the aluminum itself is breached—which takes much longer.

Abrasion resistance: Moderate.

Failure mode: Inner PE layer wears away, exposing aluminum. Aluminum is softer and can also wear through eventually.

Impact-Modified Laminated Tubes (The Gold Standard)

Major toothpaste brands like Colgate-Palmolive have patented tube structures specifically designed to resist abrasion and impact damage. These laminates incorporate block copolymers—specifically SBS (styrene-butadiene-styrene) thermoplastic elastomers—into the outer and inner layers .

The patented design includes:

• An inner layer of LDPE
• An aluminum foil barrier layer
• An outer layer blend of LDPE, HDPE, and SBS block copolymer

According to the patent, this structure provides impact resistance at least 20% greater than standard laminates . In practical terms:

When the outer layer has a thickness of 120 microns, the impact resistance is greater than 180 grams .

For toothpaste manufacturers, this means the tube can withstand the repeated compression and internal abrasion of daily use without cracking at the folds or developing pinholes.

Key takeaway: When sourcing wholesale toothpaste tubes, ask specifically for "impact-modified laminates" or "block copolymer blends." Do not accept standard polyethylene-only tubes for high-abrasive formulas.

Part 3: The Shake and Squeeze Test – How to Validate Your Tube

Before you commit to a 50,000-unit production run, you must test your specific formula with your specific tube. Here is a simple protocol used by major manufacturers.

Step 1: The Accelerated Abrasion Test

Fill sample tubes with your actual toothpaste formula (not a placebo). Manually squeeze and release each tube 500–1,000 times. This simulates 3–6 months of consumer use.

Inspect after every 100 squeezes: Look for pinholes, white stress marks, or thinning at the fold points (the areas that bend most during squeezing).

Mark the failure point: If a tube fails, note exactly where (crimp, shoulder, body, or fold).

Step 2: The Drop Test (Impact Resistance)

Toothpaste tubes get dropped. On tile floors. In warehouses. The impact-modified laminate described above was specifically designed to pass drop tests that standard laminates failed .

The test: Fill tubes, seal them, and drop them from 1 meter onto a hard surface (concrete or tile). Repeat 10 times per tube, testing different orientations (cap-first, body-first, side-first).

Pass criteria: No cracking, no leakage, no delamination of layers.

Step 3: The Heat Aging Test

Abrasion accelerates at higher temperatures because the paste becomes less viscous and particles move more freely.

The test: Store filled tubes at 40°C (104°F) for 4 weeks. Then perform the squeeze test.

Pass criteria: No measurable increase in failure rate compared to room-temperature controls.

Step 4: Request RDA Data from Your Formula Supplier

RDA (Radioactive Dentin Abrasion) is a standardized measure of how abrasive a toothpaste is to tooth enamel . The ISO standard 11609 sets a maximum RDA of 250 for safe toothpaste .

While RDA measures abrasion to teeth, it is a useful proxy for how aggressive your formula will be to a tube. Higher RDA values (200–250) indicate larger or harder abrasive particles—which means higher risk to your packaging.

Ask your contract toothpaste tube manufacturer: "What is the RDA value of my formula?" If it is above 150, you need an impact-modified tube.

Part 4: Historical Lessons – Aluminum Toothpaste Tubes and Chemical Corrosion

Before laminated plastic tubes became dominant, toothpaste was packaged in aluminum tubes. These had a different failure mode: chemical corrosion, not abrasion.

Fluoride toothpastes reacted with bare aluminum, causing:

Gas production (tubes would swell)

Black stains on the inside of the tube

Corrosion that weakened the metal 

This is why aluminum tubes required expensive internal lacquers or linings. The industry largely moved to laminated tubes to solve this problem—but the lesson remains: match your tube material to your formula chemistry.

If you are considering aluminum or metal-composite tubes for a "premium" or "recyclable" positioning, ensure your formula has been tested for compatibility. The same abrasives that wear down plastic can also scratch through lacquer coatings on metal.

Part 5: Procurement Checklist for Abrasion-Resistant Tubes

When contacting a cosmetic bottle manufacturer or tube supplier, use this checklist to ensure you get a tube that survives your abrasive formula.

✅ Ask These Questions:

"Is your tube an impact-modified laminate containing SBS block copolymer?"

If they say no, ask for the specific Shore hardness of the inner layer.

"What is the total wall thickness? What is the thickness of the inner polyethylene layer?"

Standard is 150–250 microns total. For highly abrasive formulas, request 250+ microns.

"Can you provide drop test data for tubes filled with a paste of similar viscosity to mine?"

"Do you offer an inner layer of HDPE instead of LDPE?"

HDPE has higher abrasion resistance than LDPE, but it is less flexible.

"What is your warranty against pinhole failures during the first 12 months?"

✅ Request These Samples:

Empty tubes (to inspect layer thickness and construction)

Filled and aged tubes (ask the supplier to fill with a standard abrasive paste and age them for 2–4 weeks before shipping to you)

✅ Avoid These Red Flags:

A supplier that cannot specify the exact laminate structure ("It's just standard tube material").

A supplier that offers only monolayer plastic tubes for toothpaste (unless your RDA is under 70).

A supplier that does not understand the term "abrasion resistance" or "impact modification."

Conclusion: Your Formula Deserves a Tube That Can Handle It

Toothpaste abrasives do not stop working when the tube is sealed. They work continuously—every squeeze, every shipment, every temperature cycle. A standard plastic or basic laminated tube may fail within months, leading to customer returns, damaged brand reputation, and wasted product.

The solution is impact-modified laminated tubes with block copolymer reinforcement. These tubes are specifically engineered to withstand the unique demands of abrasive dentifrice formulas. They cost slightly more per unit—typically $0.05\text{–}$0.10 extra—but that premium is negligible compared to the cost of a product recall or a wave of 1-star reviews complaining about leaky tubes.

When you source your next batch of wholesale toothpaste tubes, make abrasion resistance a non-negotiable specification. Your customers' bathroom cabinets—and your bottom line—will thank you.
