Tea bags are a very common packaging bag in our daily lives. The basic requirements are moisture-proof, itch-proof, good sealing performance, environmental protection, and fine printing. Do you also know the material of tea bags? Let’s take a look at the explanation of professional technicians:
The first type is PET/VMPET/PE, which is a high-density, high-barrier, light-shielding vacuum packaging bag composed of three plastic films, commonly known as polyester aluminized packaging bag. We can often see its use in tea packaging in our lives.
The second type of PA/PE, which is a vacuum package composed of nylon and high pressure, has the characteristics of puncture resistance, stretch resistance, high density, and moisture resistance. This can be transparent or full-page printing to make an opaque vacuum bag, which is also very suitable for tea packaging.
The third type is PA/AL/PE. The vacuum packaging bag for tea made of these three materials is commonly known as aluminum foil packaging bag. Compared with the above two types, it has higher density and better barrier performance, but the cost is relatively high. Generally, it is not recommended for customers Use this vacuum packaging bag to pack tea leaves. Of course, if our customers have higher requirements for our products, we can consider the choice of this material. But in some high-end tea, it is very common to use this kind of aluminum foil packaging bag to pack tea.
