Comparison between the structure of metal composite and non-metallic composite material structure of spout pouches

1.When you choose the material structure of spout pouch, you may choose metal composite (aluminum foil) or non-metallic composite material.
2.The metal composite structure is opaque, so it provides better barrier protection and longer shelf life than the non-metal composite structure.
3.Metal composite structure makes your spout pouch looks shinier; The non-metallic composite structure has no metal composite structure and do not has high-covering-property and bright-looking as aluminum foil composite material.
4.The printing and graphic effects of metal composite structure are better than the non-metallic composite structure.
5.The metal composite structure can’t be recycled, but the non-metal composite has the combination of recyclable materials combination which it is the direction of development in the future.

Manufacturing method of spout pouch (manufacturing processes)

The manufacturing process of spout pouches includes five steps.

1. Demand analysis

The customer puts up with the requirements, packaging product functional requirements and acceptance criteria in writing. Then the manufacturer shows the customer a prototype containing all the functional and performance parameters the customer wants.

2. Sample test

Take the existing samples as the target products required by customers for special testing, filling machine commissioning testing, finished product packaging performance testing and aging testing (shelf-life testing).

3. Product design

According to the customer’s product packaging design manuscript, adjust the design scheme of flexible packaging nozzle bag, review of composite material process selection and production industry review.

4. Test run confirmation of customized samples

Trial produce samples according to the design scheme and product scheme confirmed by both parties in writing, and the test items used in test step 2 are the basis for production confirmation of standard products.

5. Mass production manufacturing

Confirm the samples according to the test results of customized samples, sign customized processing contracts and mass produce.
