What are the materials of tea packaging bags?

1. PE bag (plastic tea packaigng bag)

Polyethylene bags or PE bags are currently widely used packaging materials. Generally, there are two types of low-density PE bags and high-density PE bags. Low-density PE bags have high moisture permeability and air permeability, while high-density PE bags are small.

The advantages of PE bags are that they are economical, cheap, and have good moisture resistance, but their disadvantages are poor light transmission and gas resistance, so they cannot be used individually for tea bag packaging. It is best to use polyethylene bag packaging with a layer of outer packaging that can block light and have low air permeability, such as synthetic paper cans, iron cans, etc.: PE bags have high air permeability, and it is difficult to solve the problem of oxygen in the packaging bag, which is not ideal the packaging material.

2. Metal tin cans

The advantages of metal tin cans are extrusion resistance and good texture. In the early days, they were mainly used in the inner packaging of PE bags for the outer packaging of tea bags. However, due to their high price and easy corrosion, rust and deformation, they have been gradually eliminated. The smell of paint and the tightness of the lid in the metal tin can are not suitable for single use.

3. Synthetic paper cans

Synthetic paper cans are the most widely used packaging materials at present. Its advantages are economical, light and beautiful, but the air permeability and moisture permeability are still high. It is not suitable to be used alone. It is best to use PE bags or aluminum foil laminated bags as inner packaging. This article is transferred from: West Lake Longjing Information Platform

4. Aluminum foil laminated bag

The aluminum foil laminated bag is beautiful and elegant, and its advantages are that it is opaque, moisture-proof and oxygen-resistant. However, the price is more expensive than the PE bag, and there will be extrusion problems when used alone. The aluminum foil laminated bag can be vacuumed or filled with nitrogen or deoxidizer. With the packaging carton or synthetic paper can, the tea storage can be completely protected from moisture, gas, light and oxygen. Low temperature storage is the best solution for tea. Perfect preservation method.

5. Glass jars, magnetic jars, wooden boxes, carton boxes

Although glass jars have excellent gas and moisture resistance, they are light-transmitting, fragile, heavy and expensive. Magnetic jars or clay jars can be protected from light, but are fragile and heavy like glass jars. If the wooden box is not handled properly, it will easily cause the tea to absorb odor and absorb moisture and breath. The carton or paper bag is easy to absorb moisture and rupture. These materials are not ideal tea packaging materials. .

6. nitrogen filling or vacuum bag packaging

For vacuum packaging, since the packaging bag will shrink, it is advisable to add outer packaging protection to avoid re-squeeze collision and to be beautiful. Nitrogen-filled packaging will expand the bag, and it should not be squeezed to prevent the bag from bursting. Both of them need to be packaged, and both have good preservation effects, but the investment is more expensive.
