PLA Corn Starch Biodegradable Tea Bag Tea Filter Paper Bag With Cotton String

Tea filter paper bags are generally composed of the following materials, which can be customized according to your actual needs.
1. Corn fiber tea bags are synthetic fibers made from corn, wheat and other starches as raw materials, which are converted into lactic acid by fermentation and then polymerized and spun. It belongs to the fiber that completes natural circulation and has biodegradability.
2. The non-woven PP tea bag and pp material are polypropylene, which is a non-toxic, odorless, tasteless milky white high crystalline polymer. PP polyester is a kind of amorphous, its melting point should be above 220, and its heat distortion temperature should be about 121 degrees.
3. The advantages of non-woven PET tea bags and PET as packaging materials are: excellent resistance to high and low temperatures, long-term use in the temperature range of 120 °C, and high temperature resistance of 150 °C for short-term use; non-toxic, tasteless, Good hygiene and safety, can be directly used for food packaging.
4. Filter paper material There are many applications of filter paper in tea bags and life. Coffee filter paper is one of them. The filter paper on the outer layer of the tea bag provides high softness and high wet strength. Most of the filter paper is composed of cotton fibers. Because its material is made of fibers, there are countless small holes on its surface for liquid particles to pass through, while larger solid particles cannot pass through.
5. Paper tea bag One of the raw materials used in this paper tea bag is abaca, which is light and thin and has long fibers. The paper produced is strong and porous, which creates suitable conditions for the diffusion of tea flavor. Another raw material is a plastic heat-sealing fiber that acts to seal the tea bag. This plastic does not start to melt until it is heated to 160°C, so it is not easy to disperse in water. Hope that helps you, thanks.
