Easy to cause of tea absorption odor absorption and air

For thousands of years of Chinese tea history, and derived a lot of tea culture. Today, tea is still the love of people, and spread to all over the world. Tea, in order to save more, keep the original flavor, choose a good tea bag is the key. Tea bag packing mark no strict rules, mainly due to the tea business is mainly produced, self-control, self marketing model, but made clear tea type, production date, origin, manufacturers and the way of drinking, will help to tea promotion and brand building. Generally applicable to the packaging of tea bag are: 1, polyethylene plastic bags, Plastic bag) 。 Polyethylene bag is a kind of packaging material is widely used currently, usually have low density polyethylene bag and high density polyethylene bag 2, low density polyethylene bag of permeability, gas permeability, high density polyethylene bag smaller. Polyethylene bag has the advantages of economy, low price, good wet resistance, poor its disadvantage is pervious to light and atmosphere is bad, can't separate for the tea packing. Can best use polyethylene plastic bags, such as synthetic paper cans, cans, adding a layer of light resistance and low permeability. 2, metal cans. Metal cans are resistant to squeeze, the advantages of good texture, the early main is packed in PE bag packaging of tea, but due to the expensive, easy to deformation, corrosion and rust has been gradually reduced. Metal cans in the paint smell and the closing of the lid should not be used alone. 3, synthetic paper can. Synthetic paper cans is currently the most widely used packaging materials, its advantage is economic, deft, beautiful, breathable, moisture content is still high, also should not be used alone, best with PE bag, aluminum foil bag packing. Aluminum foil bag with beautiful appearance, light, moisture, oxygen usage patterns as well as good barrier property, only expensive, used alone will be squeezed. Aluminum foil bag vacuum nitrogen inflator, deoxidizer, carton packaging or composite paper cans, tea storage humidity resistance, air resistance, light, oxygen release all the perfect solution, and low temperature storage is the most perfect save method of tea. 4, glass bottles, magnetic pot, wooden boxes, cartons. Glass, although to air resistance and moisture performance is very good, but good pervious to light, fragile, heavy and expensive. Magnetic cans or bottles of a similar glass jar can avoid light but fragile, heavy wooden case if mishandled, could easily lead to absorption tea absorb peculiar smell, air, broken carton or paper bags easy to moisture absorption, these materials are not ideal of tea packaging materials. 5, nitrogen filling or vacuum packing. Vacuum packing because bags will shrink, for free, and then the influence of extrusion and beauty, it is appropriate to increase the packing protection. Nitrogen-filled packaging will expand, not crowded, bag to avoid explosion. Both to add packaging, saving also have very good effect, but the investment is more expensive.
