subject: Pouch Making Machine [print this page] Plastic Pouch Bag Making Machines are a part of Plastic Bag Making Machines . However, the technologies employed for the two bag making types are different and so also are the properties. Pouch bag are generally three-side sealed while the bags produced by bag making machines are either sealed at the bottom or are side sealed.
Further, pouch bags are known to have higher barrier properties vis--vis the regular bags. Thats the reason why pouch bags are being used for food and medical packaging for these bags are known for their high level liquid, light, oxygen, and heat barrier properties.
The inner level of the pouch bag making machines are of two layers of printed, slit, and winded plastic film. The major technical difference between a regular poly bag machine and pouch bag machine lies in its welding. While the pouch bag machines have two separate sealing (welding) steps, which are immediately followed by cooling steps, which further helps generate high barrier quality, a regular plastic bag machine has only one welding step, which is not followed by a cooling step, generating lower level of barrier property in the process.
Pouch bag making machines are more expensive than conventional poly bag machines as pouch bag machines have an additional layer of technological complexity that helps in high level barrier property sealing.
