Effectively maintain the freshness and product life continuation height.

Why vacuum packaging?

Vacuum packaging is an effective method of extending the shelf life of the product, to protect it from external factors. As the air and oxygen in the air isolated, absorbing microorganisms can not survive, you can not damage the food. Although not 100% totally isolated from bacteria, but can be vacuum-packed indeed many extended shelf life, it is now largely promote the use of vacuum packaging food storage bag.

2. Vacuum packing of fruits and vegetables may be extended evaporation time, prompting increased product shelf life.

3. moat less packaging volume, convenient storage, the additional benefit of isolated external dust and the like.
