These Havercamp Thin Blue Line Balloons are 18-inch round mylar balloons featuring a police-themed design with a blue line pattern.

The balloons are made from durable plastic (mylar) and arrive deflated – simply inflate with air or helium.

Balloon Details & Measurements

What’s in the Pack?

Each package includes three 18-inch round mylar balloons printed with Havercamp’s exclusive Thin Blue Line artwork. The design features a black-and-white American flag motif with a prominent blue line running through the center – a symbol often associated with police support. The balloons are shipped flat and need to be inflated. Use air for a floating-ribbon effect or helium for ceiling-height float (balloons are not self-sealing; tie off after inflation).

Design and Features

The Thin Blue Line pattern is achieved through high-definition printing on durable mylar. Mylar balloons are less porous than latex, so they hold helium longer – often several days to a week – and can also be filled with air for longer-lasting decoration. The blue line stands out against the grayscale flag background, making these balloons a fitting accent for police-themed parties, retirements, or community events.

Are These Balloons Suitable for a Police-Themed Birthday Party?

Yes. These balloons are designed for birthday celebrations with a police or law enforcement theme. The Thin Blue Line motif is widely recognized as a symbol of police solidarity, so they work well for birthday parties, appreciation events, or even as decor for a police officer’s farewell gathering. Pair them with other police-themed party supplies for a cohesive look.

Common Questions About These Balloons

Can I use helium with these balloons?

Yes, they are compatible with helium inflation. Since they are mylar, they will float once filled with helium. The 18-inch size provides good lift. However, note that the balloons do not have a self-sealing valve; you’ll need to tie the stem securely after inflation.

How long do they stay inflated?

With helium, mylar balloons typically stay fully inflated for 3-5 days, then slowly lose lift. With air, they can last for weeks. Actual duration depends on temperature and handling.

Are these balloons reusable?

Mylar balloons can often be deflated carefully and reused if they haven’t been damaged. However, the manufacturer does not specify reusability, and repeated inflation may weaken the seams.

What is the size of each balloon?

Each balloon is 18 inches in diameter when fully inflated. This is a standard size for party balloon decor.

Safety Note

As indicated on the packaging, these balloons pose a choking hazard for children under 8 years old. Always supervise children around balloons. Discard any broken pieces immediately. Inflate using a pump or helium tank – do not inflate with mouth to avoid accidental ingestion.
