At present, more and more young people are choosing tea bag products. Generally, tea bags have two parts, one is the tea itself, and the second is the bag. Let's take you to understand the common materials of tea bag packaging.

Common materials for tea bag packaging: 1. PE bags (plastic bags) Polyethylene bags, namely PE bags, are currently widely used packaging materials. Low-density PE bags have higher moisture permeability and higher air permeability. The advantages of PE bags are economy, low price and good moisture resistance. The disadvantage is poor light transmission and gas resistance. It is best to use polyethylene bags to pack a layer that can block light and has low air permeability. PE bags have greater air permeability, and it is difficult to solve the problem of oxygen in the packaging bags, and they are not ideal packaging materials. 2. Metal tin cans The advantage of metal tin cans is anti-extrusion performance. In the early days, they were mainly used for tea packaging with PE bags. The paint smell and tightness of metal tin cans are not enough to be used alone. 3. Synthetic paper cans Synthetic paper cans are currently the most widely used packaging materials. The inner packaging is best to use PE bags or aluminum foil laminated bags. 4. Aluminum foil laminated bag The aluminum foil laminated bag is beautiful and has excellent moisture resistance and oxygen resistance, which may cause extrusion problems when used alone. Aluminum foil laminated bags can be treated with vacuum or nitrogen or deoxidizer. Using packaging cartons or synthetic paper cans can completely protect the storage of tea leaves from moisture, gas, light and oxygen. Low temperature storage is the best solution for tea. Perfect preservation method. 5. Some glass jars, magnetic jars, wooden boxes and carton glass jars have excellent gas and moisture resistance.

The above are the common materials of tea bag packaging, I hope it will help you.
