For manufacturing colored poly mailers, we use special waterproof ink to print and make sure that poly mailer printed with accurate and clear graphic pattern.

We can print even the most complex designs with our ten-color copper plate printing machine. And the image on poly mailers is waterproof, sunscreen, abrasion resistant, and will never fade away.

Being processed by the printing machines, the film takes its pattern.

Bag Making

Each mailer bag is consist of release liner, we use hot melt glue which makes the film cohere with each other. And the break glue is to ensure the closure will not be easy to open.

Using computer to control the length to make sure the sealing and cutting size with no error. For making poly mailer with handle sometimes, we punch holes with abrasive tools.
