Tea bag is a very common packaging bag in our daily life. The basic requirements are moisture-proof, anti-pruritic, good sealing performance, environmental protection and exquisite printing.Do you know the material of the tea bag?Here's a look at what professional technicians say:
The first kind of PET/VMPET/PE is a high-density, high-barrier and light-blocking vacuum packaging bag, commonly known as polyester coated aluminum packaging bag.We can often see its use in tea packaging in our life.
The second PA/PE, which is a vacuum packaging made of nylon and high pressure, has the characteristics of puncture resistance, tensile resistance, high density and moisture-proof.It can be see-through or printed in full plate to make an opaque vacuum bag, which is also very suitable for tea packaging.
The third kind of PA/AL/PE, a kind of tea vacuum packaging bag made of 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. It is generally not recommended that customers use this kind of vacuum packaging bag to package tea leaves.Of course, if our customers have higher requirements for our products, we can consider the choice of this material.But in some premium teas, the use of such aluminum foil packaging is a common practice.
