How to achieve vacuum packaging without vacuum pumping machine

by admin

if you must insist on vacuum packaging without vacuum machine, there are still some feasible methods from the technical level, for example:
1. Rebuild a room into a sufficiently closed room, and then pump out the air in the room. When the vacuum you need is reached, heat seal the prepared packaging bag, You can get the vacuum packaging you want
2. You can also completely squeeze out the air in the bag ready for vacuum heat sealing packaging by yourself. After squeezing out, heat sealing and edge sealing can be carried out to get the vacuum packaging you want
3. I believe that as long as you open the door of thought, there must be more ways to help you solve this problem, and they are much better than mine.
