Many people like DIY tea bags
because you can easily mix tea leaves by yourself
However, some news mentioned that
The material of disposable tea bags is not very safe
Can you use homemade tea bags with confidence?
Shanghai Consumer Protection Committee Shanghai Quality Supervision and Inspection Technology Research Institute has asked the Shanghai Quality Supervision and Inspection Technology Research Institute to analyze and test common tea bags on the market. It was found that the safety of the 20 types of tea bags meets the standard requirements, but many tea bags do not accurately label the production license information.
The tea bags on the market are mainly divided into six different materials: ordinary plastic non-woven fabrics (PE (polyethylene), PP ( polypropylene ), PA (nylon/polyamide), PETh+PE blend ( polyethylene terephthalate and polyethylene blend), biodegradable plastic non-woven fabrics (PLA (polylactic acid)) and paper. Plastic or paper materials that meet the standards of food-related product standards can be used safely as tea bags.
Purchase reminder
From the appearance, most plastic non-woven fabrics and paper materials are almost the same. For example, the left side of the picture below is a plastic non-woven fabric (PE) tea bag, right The edge is a paper tea bag, but the appearance is almost the same. When you touch it with your hands, you can feel the paper material is slightly rough.
Among these materials, PA (nylon/polyamide) has a strong "plastic feeling", which can be clearly seen to be relatively crisp. The material feels like " Eurogenya ", and has higher permeability than other materials.

can be used to choose the appropriate product according to the actual situation.
If you need a higher ornamentality, such as soaking flower tea in a transparent teapot, you can choose a PA (nylon) material with better permeability; if tea slices are smaller or tea Powder , you can choose a product with a fine texture to prevent excessive soaking; if the tea sheet is large and you want to speed up the soaking speed, you can choose a product with a thinner texture.

Tea bags are under the issuance management of "food-related product production license". When purchasing, you should choose a product marked with the "QS" logo to ensure product compliance.
Use reminder
Whether it is made of paper or plastic, this type of product is flammable, and the plastic material is not resistant to high temperatures, such as PLA material, the standard states that "the use temperature must not be higher than 100℃". Therefore, when using tea bags, you should avoid heating the tea water, nor should you place it in an induction cooker or oven for heating to avoid the tea bag material melting at high temperature.
In addition, due to its usage characteristics, the "tea bag" product is made of a water-insoluble material (otherwise the product will dissolve together when soaking tea leaves, which will affect the use). Therefore, after using this product, you cannot directly put it into the sewer, otherwise it will easily cause blockage.
If you find that the tea bag emits a peculiar smell during use, such as "plastic smell", it may be because the plastic raw materials used in the tea bag have impurities (such as organic small molecule ), which will be released when heated, and the product should be stopped.
