Global Aviation Standards

Carry-On Compliance Engineered

Navigating the “3-1-1 Rule” for liquids. We manufacture TSA-approved 100ml (3.4oz) bottles that pass security screening worldwide, featuring leak-proof technology for cabin pressure changes.

Understanding the “3-1-1” Standard

The Transportation Security Administration (TSA) enforces strict limits on liquids in carry-on bags. Your packaging must comply to avoid confiscation.

3.4

Ounces (100ml)

Maximum volume per container. Bottles must be marked clearly with volume.

Quart Bag

All containers must fit comfortably inside a single clear, quart-sized bag.

Per Passenger

Each traveler is limited to one bag of liquids.

Optimizing for the “Quart Bag”

Since travelers must fit everything into one small bag, Volume Density is key. Round bottles waste space. Our “Travel Square” and “Flat Oval” designs allow users to pack 20% more product into the same quart bag compared to cylindrical bottles.

Volume	US Standard	Duration (Est.)	Ideal For
30ml	1.0 oz	Weekend Trip	Serums, Oils
60ml	2.0 oz	1 Week	Face Wash, Lotion
89ml	3.0 oz	2 Weeks	Shampoo, Body Wash
100ml	3.4 oz	Max Limit	Sunscreen, Conditioner

Physics at 30,000 Feet

At cruising altitude, cabin pressure drops. The air inside a bottle expands. In a rigid bottle with a standard flip-top, this expanding air forces the liquid out—causing the dreaded “suitcase explosion.”

Our Engineering Solution:

Flexible Body: Silicone and Soft PE bottles expand slightly to accommodate pressure changes.
Valve Technology: We install a cross-slit silicone valve in the cap. It acts as a check-valve, remaining sealed even if pressure builds up. Liquid only flows when the user physically squeezes the bottle.
Triple-Seal Cap: The collar features three interlocking ridges to prevent “neck leakage.”

Travel Compliance FAQ

Are 100ml bottles strictly allowed everywhere? +

Yes. 100ml (3.4oz) is the global standard set by ICAO (International Civil Aviation Organization). However, the bottle must be labeled with the volume. An unmarked bottle, even if small, may be confiscated. We ensure volume markers are molded or printed on all our travel SKUs.

Do silicone bottles work for all liquids? +

Silicone is excellent for thick fluids like shampoo. However, it is not recommended for low-viscosity fluids containing high alcohol (like hair serums or toners) or silicone-based oils, as they may seep or swell the material. For these, we recommend our PET Travel Bottles.

Can I customize the zipper bag? +

Yes. We can customize the EVA or PVC clear bag with your logo silk-screened. We can also customize the zipper pull color to match your brand identity.
