Tea Infuser Bottles: Plastic, Stainless Steel or Titanium?
A tea infuser bottle lets you brew loose-leaf tea or fruit water on the go, with the leaves held in a removable basket. The body material decides whether it suits hot tea, cold brew or both. Here is how the main types compare, and what to specify for a bulk order.

A tea infuser bottle is a drink bottle with a removable perforated basket or filter that holds loose tea leaves or fruit, so you can brew in the bottle and lift the leaves out when the tea is strong enough. Choose the body by the drink: a clear plastic bottle shows off fruit water and cold brew, an insulated stainless steel bottle keeps hot tea hot, and a titanium bottle is a premium, lightweight option for tea gifts. BG Drinkware, a drinkware manufacturer in Yongkang, China, makes infuser bottles in all three materials, from a 320 ml titanium bottle whose cap doubles as a cup to 750 ml straw bottles and tumblers. Its plastic models use a PC body with a PP lid, with Tritan available as a body option on some models, and its stainless steel models use a 304 inner wall. Most models start at 500 pieces per colour, and a sample of an existing model takes up to 7 days.
Which type of tea infuser bottle should you choose?
Start with the drink. Clear plastic shows the tea or fruit and suits cold drinks; stainless steel, especially an insulated model, suits hot tea; titanium suits premium tea gifts. The infuser itself is usually a removable basket or filter that sits in the neck or under the lid.
| Material | Best for | Examples |
|---|---|---|
| Plastic (PC body, PP lid) | Cold brew, fruit water, sports | 700 ml dual-sip, 750 ml straw bottle, 500 ml with carry loop |
| Stainless steel (650 ml listed as insulated) | Hot tea, all-day carry | 650 ml dual-sip, 500 ml temperature display, 750 ml straw tumbler, 520 ml straw tumbler cup with tea chamber |
| Pure titanium | Premium tea gifts | 320 ml with cup cap, 480 ml screw lid, 480 ml magnetic cap |
For a desk mug, there is also a 400 ml business mug with a tea filter; for pots, see insulated teapots with strainers.
What should you check on a plastic infuser bottle?
The body material and the claims you plan to make. BG Drinkware's plastic infuser bottles use a clear PC body as standard and a PP lid, with Tritan available as a body option on the 500 ml and 700 ml models. If you want to market the bottle as BPA-free, specify Tritan for the body and check every other part.
PC and Tritan are both clear; of the two, only Tritan is made without bisphenols, according to its maker, Eastman, while PC is made from BPA. Lids are usually PP. For the differences and the claims each supports, see Tritan water bottles and BPA-free water bottles in bulk.
Stainless steel or titanium for hot tea?
Both take hot tea. An insulated stainless steel bottle is the practical choice for daily use and keeps tea hot for hours. Pure titanium is lighter and suits premium gifts. BG Drinkware's titanium tea bottles use titanium for the body, with Tritan listed for some lid parts, and the 480 ml models can be supplied in gift boxes.
Check whether a model is vacuum insulated if the tea must stay hot for hours. Leave tea leaves in the infuser only as long as the tea needs; lift the basket out so the tea does not turn bitter. For the metal choice, see titanium vs stainless steel water bottles; for how long hot drinks stay hot, see how long a thermos keeps coffee hot.
How do you clean a tea infuser bottle?
Take the infuser out and empty the leaves straight after use, before they dry in the mesh. Wash the basket, lid, seal and bottle in warm soapy water, brush the mesh from both sides, rinse and dry everything open. Tea stains on steel come off with a baking soda soak.
Infuser bottles have more parts than a plain bottle, so the care card matters. See how to clean a stainless steel water bottle and easy-to-clean water bottles.
How do you order custom tea infuser bottles?
Send the model, capacity, material, colours, logo method, packaging, quantity and terms, and say which parts should be Tritan on a plastic bottle. Most of BG Drinkware's infuser bottles start at 500 pieces per colour. A sample of an existing model takes up to 7 days.
Bulk production takes 7–12 days after the sample is approved. The 480 ml titanium models can be supplied in gift boxes, and the plastic 500 ml and 750 ml models pack 60 pieces per carton. For gifting, see custom drinkware gift sets; for the range, see water bottles.
Tea infuser bottle FAQ
Short answers to the questions buyers ask most about tea infuser bottles: whether they suit hot tea, which material to choose, how to clean the infuser and how many to order. Each answer uses the details listed on BG Drinkware's own product pages.
Can you put hot tea in a tea infuser bottle?
Choose an insulated stainless steel bottle for hot tea; titanium bottles also take hot drinks, but check whether a model is vacuum insulated. Clear plastic infuser bottles are mainly sold for cold brew and fruit water, so check the maker's temperature guidance before using one for hot drinks.
Are plastic tea infuser bottles BPA-free?
It depends on the plastic. A Tritan body is made without bisphenols, according to its maker, while PC is not. BG Drinkware's plastic infuser bottles use PC as standard, with Tritan as an option on the 500 ml and 700 ml models, so specify Tritan if you plan to make a BPA-free claim.
How long should tea stay in the infuser?
As long as the tea needs, then lift the infuser out. Leaving leaves in all day can make the tea bitter. Most infuser bottles let you remove the basket and keep drinking, and some, such as straw models, let you drink with the infuser still fitted.
What is the minimum order for custom tea infuser bottles?
Most of BG Drinkware's infuser bottles start at 500 pieces per colour. A sample of an existing model takes up to 7 days, and bulk production takes 7–12 days after the sample is approved. Say which material and parts you need when you ask for a quote.
